No bootable device after failed Windows 7 installation via Bootcamp While trying to install Windows 7 via Bootcamp on my MBP Retina today I really messed up.

After getting into the drive selection in the Windows installation utility I deleted the other partitions (3 of them - as I remember one 60mb, one 200mb,) to get more space for my Bootcamp partition. After I deleted them (not formatted anything - just deleted) it just showed one huge unpartitioned disk with the whole ~250gb of my ssd. I realized that I messed up and exited the installation routine just to find out that I can't boot into anything right now.

When I do a regular restart it shows an error message "no bootable device - insert boot disk and press any key" - I also tried the "alt+cmd+r" method which doesn't do anything...

Please send my any ideas/tips how to go on - I have really important documents on that machine and I haven't made any backup.

UPDATE:

I tried to connect it to a second mac via thunderbolt/target disk mode and get the data with testdisk but i'm kind of stuck - when i connect it first it says something like "the medium couldn't be read" but I'm able to see the ssd via disk utility! But what medium should I select in Testdisk?

It looks like you manged to delete a Hidden partitions.

One is Called EFI and it is about 200mb.

The second one is called RecoveryHD and it is about 600mb.

There was a reason for them to be hidden, but if you have the Debug menu show all on, they will show.

The good news is your data is still there, if you did not do further damage.

If you have a bootable USB (always) then use it to start up.

Meanwhile if you must recover your data, use a second Mac and run the Target Disk mode to recover.

Using 3d party disk repairs wont help here, you need to get the EFI back on to your disk, that is only provided by Apple.


Why are iPhone X photos higher quality than iPhone 7? My relative has an iPhone X, while I have both an iPhone 7, and a DSLR camera.

At a recent family event I compared his photos with mine and his iPhone X photos look almost as good as DSLR. I did a quick Google search but couldn't find an obvious answer.

Is the most significant improvement hardware-based, or software-based? If it's the latter, can older iPhones be configured to get these benefits (I noticed his images are in HEIC format which my iPhone 7 only seems to use in Burst mode)?

In addition to the answer offered by Nimesh, there's also the issue of how you compared the photos.

My assumption is that you were just checking them out on your iPhones, and this probably explains a lot of what you noticed because the display on an iPhone X is leaps and bounds above that used in an iPhone 7. More specifically:

the iPhone 7 incorporates a Retina HD LED-backlit LCD display with a resolution of 1334 x 750 pixels
the iPhone X uses a Super Retina HD OLED display with a resolution of 2436 x 1125 pixels

Not only is the iPhone X's resolution much higher, but it uses an OLED screen as opposed to an LCD one. Photos viewed on this will appear to look significantly better than those displayed on an LCD.

In other words, while the iPhone X is definitely taking better photos, how much better they're looking is exaggerated if you're viewing them on an OLED display, as opposed to viewing the photos on the same display.

So, for a valid comparison you'd need to view the photos from both devices on the same display (e.g. on the same computer) to get a better sense of how much difference there was in the quality.


iPad 3 as recording device - How to Connect Firewire 400 from a PreSonus device Have:
iPad 3 (Apple 30-pin connector)
PreSonus Firestudio (firewire 400 output)

How to connect them?

You don't. Firewire isn't compatible with a full fledged USB controller and the 30 pin connector isn't even a full USB connection to connect peripherals.

Sell the Firewire device and buy a device that will work with the iPad is sadly the best advice I have for you.


External SSD for MacbookPro - get the right speed? I have a MacBookPro, Mid 2014.
In the system information, I see that I have an USB 3.0, with speed up to 12Mb/s.
This is already different from what I see on official specifications https://support.apple.com/kb/sp703?locale=en_US where the USB port speed is given as "up to 5Gbps".
So the question is: I want to buy an external SSD drive, giving priority to speed. But will it be meaningful to buy an SSD that boasts up to 550MB/s (68Mbps) when I have only 12Mbps?
Or should I believe that I have 5Gbps?
I'm a bit confused

The external USB3 ports on the MacBook Pro Mid 2014 are definitely capable of 5 Gbps, and so it it is indeed meaningful to connect a SSD that way.
Note that the actual speed of the USB links changes depending on what you connect to it. So if you connect some older, slower device - such as a for example an old USB mouse - you would see the speed listed as being significantly slower. The same can happen if you connect an older USB hub, or you connect several devices to the same port of differing speeds.
Also note that the MacBook Pro has internal USBs for things like the keyboard, trackpad and camera. The speed of these is irrelevant in terms of the performance you'll see with externally connected devices.


Word for Mac - Equations I am finally making the switch from Windows to Mac and one big impediment/irritant is in the switch from Word for Windows to Word for Mac.  I do a lot of mathematical work and have a large number of Word documents with equations in them from the Word 2010/2011 equation feature.  In the Windows version, this is just a Pi symbol that I click to start typing an equation, and I can insert functions, summations, fractions, exponents, things like that really easily.  I have Word 2008 on my Mac right now and none of those documents will even open.  I could try updating to the newest version of Office, but I'm worried that I'll do that, they still won't work, and I'll be out a lot of money.

I'd like to not only open all these documents but also to continue writing mathematical documents the same way I'm used to on Windows.  What can I do?

In a blank document, go to Insert → Object → Microsoft Equation Editor to insert new equations. (If you were using Word for Mac 2011, it would be Insert → Equation.) Do you see that menu item or not? If not, note that Equation Editor isn’t part of the default install, and you might not have it. You’ll need to pop your install disc back in and do a custom install of it. Check the Value Pack Installer.

Can Macs connect to VPNs with MS-CHAPv2? I've been provided directions with how to connect to a VPN on a remote server, but it's just one of those simple "Connect to network, VPN, etc." wizards from Microsoft Windows that establishes a VPN over the WAN Miniport interface. I can connect just fine on Windows.

However, how would I go about this on a mac? I've tried configuring a VPN through the network preferences, but there's no settings anywhere to specify MS-CHAPv2, so authentication fails using all other methods that Mac supports.

Is there any way that I could get this working? I've been looking online but can't really find anything solid. Do I need to find some random VPN client or something that supports this? A little annoyed and stumped here and any help would be greatly appreciated.

I found an answer over on Superuser that seems to involve some work in the terminal. Certainly not an ideal solution...


Software/utility to completely erase cookies/cache What software (or using any other in-built tools) can I use to clear (by clear, I mean scrub from the disk) the cache & cookies in browsers, without affecting the bookmarks etc. I use firefox 4.

Does deleting them from the browser and running disk util to write zeros on the free space do the trick? Also, this is a shared laptop, so not much chance of drastic steps.

The easiest way is to use a free (or paid) utility to do it for you.

Onyx is a free one that does the job, you have an option to clear your browser's different values:

Cocktail is a paid ($14.95) nice utility too, that does what Onyx does and the UI is a little bit more elegant and give you some more flexibility:

Of course, you will have to make sure that you securely empty your thrash if you really want to make sure nobody has access to deleted stuff.

Cocktail has a nice option that may interest you in this regard:

…which should cover your secure concerns :)

(if OnyX has a secure delete, I couldn't find it in the preferences).


Is there any way to convince Apple Mail to write its configuration as text Plist files instead of binary? I'd like to revision-control my mail configuration (both the preferences and the mailbox rules -- especially the latter) but Mail insists on rewriting its preferences as binary plist files as soon as it opens. I'd like to have it keep them in text or XML format, which would allow me to keep them in revision control in a meaningful way. Yes, I could keep them as binaries, but those are awful and result in a lot of ugly changesets.

Probably not, but you could use plutil to convert the binary plist to XML and keep the results in your revision control system.


Receiving spam from myself For the last few weeks, I keep getting the same spam message sent by my iCloud account to my iCloud account. I'm not seeing any other weird behavior in my iCloud.

I did change my linked email to a different one and changed my passwords in both several times but I'm still receiving the emails. How do I get them to stop?

I suggest you to go to Mail.app → View → Message → All Headers and analyze that headers.

If appears any server not related to iCloud, then copy the content of Mail.app → View → Message → Raw Source window and report in spamcop.net.


Which connection interface should I use with my next external HDD? I've recently bought a new macbook pro.

Since my old backup hard drive is failing, I'm planning on buying a new one.
I don't want to spend a lot of cash and I would like a decent amount of extra space, so I'll be going for an HDD not an SSD.

Yet I'm wondering, what would be the best data protocol to buy (USB, FW800, Thunderbolt)?

I'd say thunderbolt is overkill since the speed of an HDD won't come near the speed thunderbolt can go (and it's pricey, and has low availability).

Is it worth it to go FW800 over USB2/3 (my mac has USB2 anyways)? I just want the speediest solution.

If you simply want speed, then FW800 is faster than USB2 (you do not have USB3).

USB has drawbacks which result in a lower then promised sustained speed (FW800>FW400>USB2).

Edit: I've done some research to get real world numbers. While the theoretical speeds are (100MB/s vs 50 MB/s vs 60MB/s) the real world results result are (90MB/s vs 30MB/s vs 30MB/s) due to limits cause by bridge-chips (german source). Since hard drives allow transfer speeds above 30MB/s, you should take FW800.

If you want to be upgrade safe for a future Mac, I'd take USB2/3. Firewire support is probably going to be dropped in the near future (see Macbook Air).

Thunderbolt is overkill - as you said.


Is it possible to block the Wifi access for an individual application(Mac OS X 10.7) I would like to disable the network connection for an individual applications in Mac OS X 10.7

Lets say an example, I don't want to provide the network access for photoshop application.

Is it possible ?

Any help on this is appreciated.

Thanks

Install and use LittleSnitch to easily block outgoing network connections on a per-application basis. (Can also configure incoming blocks as well, if you wish.)

If you're trying to defeat network copy protection in Adobe Photoshop and certain other apps -- you can prevent Photoshop from "phoning home" across the internet, but you can't prevent it from detecting multiple serial numbers on the LAN. At the LAN level it uses protocols other than TCP/IP to see if other same-serial-number copies of the program are running. LittleSnitch can't recognize or filter these non-TCP/IP communications.


Finding stolen AirPods I recently had my AirPods stolen from my bag at college. Soon after, I attempted to locate them using the Find My iPhone app but was unsuccessful in doing so. The AirPods appeared grey in the app and only showed the last location I know I opened them.

Since then, I have repeatedly checked the app, but the location has not been updated since. Unlike other Apple devices, it appears that there is no option to 'lock' the device as there is for iPhones within the app. It has been difficult to work around the problem.

After talking to other people, it has come to my attention that it may have been possible for the person to have reset the AirPods after taking them and this is why I am unable to locate them.

I would be extremely appreciative if someone could give me advice on a course of action recovering the AirPods using the Find My iPhone app. I have already talked to the staff at my college but there is very little they can do which is why I'm hoping I can locate the AirPods myself.

AirPods only note their location in Find My iPhone when they pair with your device. They have no built in location tracker and no way to communicate to the internet except through your paired iPhone or iPad or Apple Watch.

The person may have reset them, but even if they didn't you wouldn't get any location updates unless the thief walked by and remained in range of your device long enough for the AirPods to pair.

The reset doesn't change the identity of the bluetooth module so that may have nothing to do with locating them, either.


MacBook Pro - How to resume APFS decryption process? I was decrypting a drive from Recovery menu and I restarted machine because it was taking a lot of time but now the decryption has been Paused at 42%.

I listed all available options using diskutil apfs and there isn't any option to resume/revert decryption process. I also tried to verify/repair disk option but it is still paused.

I found this command but it is for other file system.

diskutil cs revert /Volumes/title_drive -passphrase

As this file system is new so I was not able to find any helpful material on any site.

Please tell me, how can I resume the decryption process.

The process is totally automatic in High Sierra and there is no command to resume the decryption process other than connecting the Mac to power if it's a portable Mac.

The Apples new file system APFS works differently then older file systems HFS+. The detailed guideline along with new feature detail can be found here.

Now, whenever you'll unlock volume the pending/paused encryption/decryption process will start automatically. But there is a condition, the machine (in my case, MacBook Pro) must should be plugged in. So, whenever you'll unplug the decryption process will stop immediately even if the battery is fully charged since this is presumably a maintenance task that shouldn't deplete the battery energy at any time.


How can I remap the volume buttons for custom use? First of all, I only want to disable the standard volume buttons - I do not want to disable the buttons to change brightness, launchpad...

I need this because I want those buttons to trigger scripts for finer volume adjustment using FastScripts.

Karabiner (Formerly called KeyRemap4MacBook)

allows to intercept the keyplay.

Assign your scripts for fine volume adjustment to F11 and F12 (actually it's a combination of fn+vol. up/vol. down).
Download and install Karabiner.
Open the Karabiner preferences via the menu icon, which is a black square (like a keyboard key), somewhere in your menu bar.
In the Tab Change Key select the options:

Volume Down to F11
Volume Up to F12
F11 to Volume Down
F12 to Volume Up

This will switch the behavior of the function keys with the volume keys: Now you can use fine volume adjustment with one touch and the usual volume adjustment using fn+vol. up/vol. down.

Note that there is also an option "Fine grained volume controls" that enables fine grained volume controls by default, so you can do this purely within Karabiner, without any other scripts.  You can find this in the giant list, under "Change F1..F19 Key & Functional Key" and then the submenu "Change Functional Key".


Can I make the Podcasts App play my unplayed podcasts in chronological order? The new Podcasts app is pretty swell. I'm particularly fond of the 'Unplayed Episodes' button that generates a playlist of all my unplayed podcast episodes, on which I can just hit 'Play' and let a half a dozen episodes of different podcasts just run in order, without having to actually edit or manage a playlist.

But there's one problem: They play newest first. Is there any way to change this playback order so that I can hear my oldest unplayed podcasts first?

Unfortunately, no.

The combined Unplayed Episodes playlist has no settings and defaults to newest first.

As of version 1.01, you can only sort individual subscriptions by oldest first.

Even if you go through the trouble of changing each individual subscription preference to oldest first, Podcasts app will still keep the Unplayed Episodes playlist sorted to newest first.


Automating terminals at startup Is there any way to automate a bunch of terminals starting up at once. I find myself opening several windows and running the same sequence of commands in various tabs. I'd like to stick all this in a single shell file (so I could keep it in version control, share it, etc) rather than have to add it all to a GUI.

Ideally with iTerm, but automating with any terminal program would be interesting to hear about.

You could run your shell script from ~/.bashrc. Then no matter which client you use it will be executed when you open a new shell.


how to keep low-res photos handy, while archiving high-res versions? I have a laptop with a 256Gb SSD that always seems to be full.  A lot of my disk space is used by photos (in Aperture and iPhoto).

What I really want is to have low-res versions of all my photos on the SSD with high-res versions backed up to an external hard drive or Time Capsule.  If I'm visiting family and someone spontaneously decides that they want to see Christmas from 4 years ago, I want to at least have low-res versions to show, even if I need to go home to my external hard drive for high-res versions.  And I want it to sync, such that if I decide while I'm on the road that some photo is crap and delete it, that it deletes the high-res version when I plug back into my external hard drive.

This seems so logical to me that I'm constantly surprised that this problem doesn't seem to be solved.  Aperture "vaults" appear to be just a backup copy of the entire library; they don't let you delete the high-res versions from your main computer.

Am I missing something?  How do you keep photos from filling up the limited space on an SSD?

Depending on how your Aperture library is set up, I think it will do this automatically.

If you use a referenced library (see the Aperture manual for more information on managed vs referenced), Aperture won't store the hi-res masters in its own library - it will leave the file management up to you. It does, however, keep a low-res preview of the image in the library. So you could store your images on an external HDD, but still have access to the low-resolution previews when the HDD isn't available.

I haven't tried this myself, so I'm not sure how small the previews are, but I'm guessing they'd be good enough for the purpose you're describing.


iPhone battery runs down frequently? My iPhone's battery runs down frequently after being fully charged, what can i do?

Based on the "iphone" tag on this question, I'm going to assume you're talking about an iPhone battery.  The lithium-ion batteries used in portable devices have a limited "lifespan" (number of charge cycles) -- their maximum charge capacity diminishes slightly every time they are charged.

Apple has published tips on battery maintenance as well as general tips to get more life out of iPhone batteries.

Unfortunately, iPhone batteries cannot be easily replaced by consumers, but Apple will replace them for $86 with a one-week turnaround.  There are also third parties that offer to do this cheaper, but it may affect your warranty if they are not authorized technicians.

Finally, if you are really into DIY, you can buy the parts online and replace it yourself (about $30 including tools and shipping), though some have suggested that this is a difficult procedure.


Local copy of Xcode (Lion) I have old macbooks with Lion. Because these are testing machines for different tasks, many reinstallations happens. Downloading the Xcode from the AppStore every time (2.5GB) is slow. Further complicating matters is the "download size" of Xcode 4.3.6 (the latest Xcode for Lion) is 2.5GB, but the application size in /Applications is 3.5GB - so happens some unpacking or so.. and want ensure than the simple copy of the Xcode.app is safe as I don't want a heavy solution that requires:

time machine
SuperDuper or command line dd nor any other disk-copy utility
any other backup strategy - incremnetal or not...

Simpy want to know:

is enough copy the Xcode.app from the /Applications folder to another machine?
when I just installed the Xcode from the AppStore, is enough copy the Xcode.app to another notebook (same HW, same OS version).
if not - why - what is the difference in the RESULT (exactly) between copy and installing Xcode from the AppStore.

How can I safely reuse one download for multiple installs?

I believe your best option is to use SuperDuper! to make a backup image of each machine with a clean instal of the OS and any software you know will be needed for testing every time. Once you have created the backup image it will make reinstalls much faster and easier.

I have not tried copying the Xcode.app before, but I think you would be missing a lot of preferences and command line tools if all you copied was the app.

EDIT:
If you download Xcode from the App Store and copy that Xcode.app package to another machine without ever launching it, it should work fine. There should be no preference files or app support until after the first time Xcode is launched. From my point of view though, this is not a very useful way of putting test/development machines together though because when I use Xcode I have it set-up a certain way with command line tools installed which would need to be done on each machine when you copy the Xcode.app.


How can I make a note in a Kindle book in Kindle for Mac? On the Amazon site, it says:

  Click on any word or click and drag over a passage to create a highlight or add a note within a book. Once you've selected text, a pop-up box gives you the option to Highlight, Add Note, Copy, or the More dropdown menu.

But that doesn't seem to work in the Kindle application I have on my Mac.

Is there a way to add a note in a book in Kindle for Mac?

You have to download the latest version (1.8.1 as of this writing) directly from Amazon, the updater doesn't seem to pick it up automatically.


Does Thunderbolt support chaining multiple monitors to a MacBook Pro? This has always been a big want for me. I love using multi-monitor setups but only want a single laptop. Does the 2011 MBP Thunderbolt support chaining multiple monitors together? I know that you can add a monitor and say, a few hard drives, but can you connect it to 2 27" monitors and your flat screen TV (for example)? Thanks!

The MacBook Pro allows two Thunderbolt displays to be hooked up. apple.com/displays


Does "Never Play This Song" apply to one station, or all stations? Just curious if every time I press that X, it means I'll never hear a song. Some songs just aren't right for a station, but it doesn't mean I hate the song. Curious if it bans that song forever from all my stations or just one.

I believe the "Never Play This Song" applies to just the one station.

Apple clarifies this in their page for Apple Music Radio - https://support.apple.com/en-us/HT204944

"While listening to your custom station in Apple Music Radio, tap or click the star icon star icon to fine-tune your station. Tap or click the star again to tell us to Play More Like This. Tap or click the x icon x icon to tell us to Play Less Like This or Never Play This Song."


Unable to turn on bluetooth with Yosemite I can't for the sake of it turn my bluetooth on in Yosemite.
It is greyed out and the menu bar shows bluetooth disabled with a grey wiggle line through it.

Anyone have a solution?

Hopefully you found the solution by now, but I have had this issue numerous times with Yosemite. I have to shutdown the system completely (not a restart) and then it miraculously comes back on. It just shuts off completely for some unknown reason.


KeePass application with synchronization support on a Mac? I'm looking for a KeePass application for use on Mac OSX.

KeePassX and KyPass 3 but both lack support for synchronization of KeePass 2 (.kdbx) databases.

KeePassX will just plain overwrite the database.
KyPass 3 will do you the courtesy of alerting you of a potential data loss before overwriting a database.
KeePass is a third option, but I have't not been able to get the application to work, let alone test synchronization.

What Mac OS X apps support synchronization of the kdbx database that stores credentials in this open source format?

MacPass is an open-source KeePass client for OS X that is able to sync KDBX files.  I came across this looking for an answer to this question myself, finding no real satisfactory answers elsewhere.


What inputs does an iPad have? What possible ways of reading input does an iPad have? Right now I can think of:

Touch screen (multitouch I believe?)
Camera
Brightness adjuster (How does that work? Could it be used for
anything other than the brightness adjustment?)
Orientation detector
The standard input buttons

Is there anything I'm missing?

Besides the obvious USB / Lightning connector and the WiFi / Cellular / Bluetooth technology, the iPad has:

Volume up / down switch
Silent / Screen rotation lock
Microphone
Built-in speaker
The gyroscope
The accelerometer
The ambient light sensor
Micro-SIM card try
Facetime / iSight camera
Multi-Touch display

Bear in mind that these are for the latest version.


Terminal command ls/cd not finding any files on external harddrive I'm having a bit of trouble with my external hdd and terminal. I've been able to access files on it via terminal in the past, but since I upgraded to El Capitan I can't seem to find anything on my external hdd. I can navigate through it and use stuff from it fine using Finder.

But then when I try to find anything using Terminal:

I'm really confused here — this has never happened before. Any ideas?

edit: did ls -l /Volumes:

lrwxr-xr-x   1 root  admin    1 Oct  4 22:05 Macintosh HD -> /
drwx------+  2 Shan  admin   68 Oct 11 17:29 ShanStore
drwxrwxr-x  17 Shan  staff  646 Oct 29 21:41 ShanStore 1

Not sure why it's showing two external hdds — I only have the one

For whatever reason, the drive got mounted/attached under /Volumes/ShanStore 1. The number will not be shown in Finder but bash (in Terminal) is a bit more strict here.

To fix:

Unmount/eject the drive in Finder und shut down the drive
Run sudo rmdir /Volumes/ShanStore /Volumes/ShanStore\ 1 (you'll probably get an error message about a non-existing /Volumes/ShanStore\ 1, which is ok)
Run ls -l /Volumes to (hopefully) see /Volumes/ShanStore gone
Restart the drive again


Mail - Subfolders on own IMAP-Server are all shown under INBOX I've got a problem with my folders within the mail app.
As you can see, I've got three accounts:

an exchange server
my iCloud server
an own imap server

The problem with the IMAP server is, that all of the subfolders are shown under the INBOX and I can't move them to the server-root, because, as you can see down further I have no possibility to move them to the root.

I'm not quite sure wether this is the correct community for this question..
but, would love to hear some tips :)

You can try adding a root folder in Accounts under the Advanced tab.

Mac Mini with lots of I/O errors and related issues, trouble identifying culprit Setup:
Mac Mini 2011 with two drives:

SSD with OS X Yosemite and admin account home folder
HDD with my user home folder

Symptoms:
It began as many months of seemingly random slowdowns/beach balls, but the issues would go away (often after reboot, Safe Boot restart, or reinstall of OS X) then resurface periodically.  Recently (last week), problems escalated to being completely unable to login to my user account (logging into the admin account works fine).  When I try to login to my user, the loginwindow process crashes and it returns me to the list of users.
In Console, I’m also seeing lots of 'kernel: disk1s2: I/O error's (this is the HDD with my user home folder).  By lots, I mean it ranges from 1 per minute to 1 every 10 minutes or so.  Obviously the 3 big suspects are the HDD, the SATA cable, and the logic board.
Troubleshooting:

From the Admin account, I created a new user account stored on the
HDD.  I have been able to login to it, but it is exhibiting similar
symptoms to what I observed in my primary user account (extremely
slow, lots of beachballs).
I reinstalled OS X and tried multiple Safe Boot reboots (both of
which have previously helped when encountering slowdowns and random
beach balls).
I replaced the SATA cable with no improvement.
I removed the HDD and used it as an external USB drive on another Mac
and was able to access/scan the whole drive with no observed issues
or slowdowns and no I/O errors.
Disk Utility ‘Verify Disk’ comes up clean every time and the
S.M.A.R.T. status is Verified.
I ran the Disk Warrior hardware test and it said the drive is
functioning normally.
I ran the Apple Hardware Test (Diagnostics tool) multiple times (both
quick and extended) and it has never reported any errors with the
drive, logic board, RAM, or any other hardware.

It sort of feels like a hard drive problem, but I have no proof of it.  Since everything else comes up clean, I'm left with the logic board, but no way that I know to test it other than the Apple Diagnostics tool (which shows no problems).  I’d hate to waste money on replacing the hard drive or on repairing the logic board without knowing which is failing (if either).
Any suggestions on further troubleshooting steps, particularly to determine if it’s the hard drive or the logic board?
Side note - yes, I have backups to restore from :)
Thanks

Look at something like Scannerz because it was designed to find those types of problems. Here's a link:

http://scsc-online.com/Scannerz.html

Scannerz is fault detection software that monitors and looks for signatures associated with various types of logic board, drive, and system failures. I suspect either a cable, connection, or logic board problem.

I hope it's OK for me to post that link and info.


How can I flip the dash and underscore keys in macOS Sierra? I'd like to remap dash to underscore and vice-versa in macOS Sierra. I type underscore way more frequently than dash, so this is a desirable lifehack. Karabiner doesn't work anymore in Sierra (and the Elements version is a non-starter at this stage), and I can't seem to figure out how to do it in BetterTouchTool or Keyboard Maestro. There seems to be loads of ways to remap keys for shortcuts, but flipping the primary and shift output from the same key is elusive.

Connecting Dell U3011 to retina MacBook Pro via mini DisplayPort I am trying to hook up my Dell u3011 to my retina MacBook Pro using a mini DisplayPort to DisplayPort connector, and finding myself a bit perplexed as to why it doesn't work. Basically the top resolution that Mac OS X allows on the external display is either 1080p or 1280x1024(scaled!), while monitor's native resolution is 2560x1600. I Googled around and people recommend using SwitchResX tool, to fix the issue, but I am curious if there is a way to force the correct resolution with native tools(cli or some obscure settings?).

Note: I am using OS X Mountain Lion. The miniDisplayPort to DisplayPort connector is from Monoprice.

Try resetting the PRAM and see if it detects the proper screen resolutions. If that still doesn't work, you could try cscreen (a command line tool to set a resolution) or SwitchResX.


Cannot assign 'Open With' to a specific application using Mountain Lion I am using Mountain Lion 10.8.2 and Coda 2.0.4.

I want all my .js files to open with Coda (currently js files are assigned to Safari).

When I do a 'Get Info' and change the 'Open with' application I try to select Coda 2 but it immediately bounces back to Safari.

If I choose any other application, like Firefox, XCode, etc it takes it. It only seems to hate Coda 2.

Any idea what's the issue?

Have you tried rebuilding the Launch Services database by running /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed?

If that doesn't work, you could also try defaults write com.apple.LaunchServices LSHandlers -array-add '{LSHandlerContentType=com.netscape.javascript-source;LSHandlerRoleAll=com.panic.Coda;}'. Applying the changes requires restarting (logging out and back in isn't enough).


How to create custom Automator tasks for distribution -- OS X 10.10 Problem

I would like to make custom tasks for Automator to send to friends who are learning or even just to make new Automator apps easer to write without having to repeat the same tasks over and over.
For example:
run shell command (uptime) -> speak text -> copy to clipboard

Would it be at all possible to make a task called Uptime and use one task instead of three?

Any help would be appreciated :)

Using your example, "For example: run shell command (uptime) -> speak text -> copy to clipboard" and to answer your question, "Would it be at all possible to make a task called Uptime and use one task instead of three?", yes... Simply add one Run Shell Script Action  to your Automator Workflow and add the following code:

uptime | pbcopy
pbpaste | say

This pipes the output of uptime to the clipboard and then pipes the content of the clipboard to the say command.  The output of the uptime command is still on the clipboard to paste elsewhere, either by additional commands and or using the keyboard and or other normal methods of pasting from the clipboard.

Note: I'm assuming that when you say "use one task instead of three", you're actually referring to an Automator Action, e.g. Run Shell Script, not the number of commands written into that on Action.

White screen for 10.12.2 upgrade on mac mini When I try to upgrade to 10.12.2, my mac mini reboots to a white screen. The mouse is responsive, but nothing is drawn. In previous upgrades, I could get past this by holding SHIFT for safe mode; and then the upgrade would complete. Not this time. There are no USB devices except the keyboard plugged in. I've reset PRAM/NVRAM, no change. I can boot to recovery. Any other suggestions?

I experienced the same white screen issue after updating to 10.12.2 and was forced to restore from a previous time machine backup (after trying to repair the drive, resetting the PRAM/NVRAM and booting safe mode failed to work).  Stupidly, I tried updating to 10.12.2 again on the restored version and during the reboot process it went back to the white screen.

Don't install 10.12.2 if you have this issue.


Mac Encrypted HDD Please help! Hi everyone I have encrypted a partition of an external hard drive from the mac desktop.
I pressed that key button then pressed memorable and it changed my entire password unknowingly.
I need help.  All I know now is that its 12 characters long.

I have loads of pictures and videos on there from when my kids were born. Please someone help me I beg you.
Also please don't tell me its impossible because nothing is impossible.

You could see about getting a quote from a data recovery team to attempt to reverse engineer your situation. Since you are fairly certain that the key is 12 characters long, that significantly reduces the number of passphrase that must be attempted to unlock the volume.

Also, paying a professional to do this means you are only renting the equipment and/or software to try each combination rather than needing to fund that yourself.

Since the encryption takes time and is reversible, it clearly is possible to brute force this, but I would get a quick feeling for how much of the drive is encrypted by saving the output of diskutil list and diskutil cs list and then ejecting the drive and powering it off until you can get it in the hands of a pro.

Also, you do have to re-type the entire password manually and then confirm the operation, so perhaps you just had a normal software error and didn't establish the encryption. Best of luck with the recovery. Losing data is no fun and having  baby pictures only on one drive is not something I ever like to confront - yet it does happen and the pain is awful in most cases to lose those artifacts of the time and memory.


Orientation won't unlock I have an iPad Air 2. I was having problems with volume until I loaded the 8.1 OS. Now I have volume but my orientation is locked. I checked, orientation is not locked in the slide-up menu and I cannot find in Settings/General where I may have it locked.

Orientation lock was an issue with early versions of iOS 8.

Simplest fix would be to update to 8.3


How to make a Mac forget it ever saw an iOS device? I need this just to be able to test how the machine responds to the first time a device is plugged in - without needing an unlimited supply of 'new' devices.

I connected a 'foreign' iPad [my partner's, not synced to this machine but to her own] to test Photos app's response.  It auto-launched.

Now I want to try again, let it 'see' the device for the first time - so I'm trying to discover what keeps the record of which devices were connected & if I can clean it of just one device without damaging my regular devices' behaviour.

Closest I can find is How do I make iTunes 'forget' a device in Mavericks? which has some discussion regarding Sync Services - but I'm not sure if that's heading in the right direction.

Also relevant - How can I prevent iPhoto from opening everytime I plug my iPad/iPhone? - which is my eventual aim.

I'm not sure exactly, but I can help you figure out which files changed after you plugged in the device.  Hopefully you're comfortable with Terminal.

Start a timer.  Plug in your new device, treat it like you would any other new device - trust it, let it sync, whatever.

Once that's all done, stop your timer, see how long it took and round up in minutes.  Let's assume it took 5:18.  We're going to round up to 6 minutes.

$ find ~ -type f -cmin -6 > ~/Desktop/files_modified.txt

Now you have a file showing all of the files that changed in the last 6 minutes.  Some of these files are going to be relevant and most aren't: when I ran this experiment I got lots of files changing related to Safari, for example.

Good luck, I hope that helps.


Apple TextEdit - where is the file being saved? I used to use Save As… to remember the directory I was saving a file in, but that seems to have disappeared with the latest OS.

I have a file open in TextEdit. How does one go about finding the directory that this file is currently being saved to? I can see the name and I can "open recent" (which just displays the name), but, once open, I can't actually figure out how to determine where this file is located.

Try pressing Command⌘ while you left-click on the document window title text. It will show the folder hierarchy in a pop-up menu.


MacBook Pro 2019 playing sound while updating to 10.14.6 On my new MacBook Pro 2019, while updating to 10.14.6, sound started playing before the update was even finished. It was autoplay from a tab I had on Chrome before updating. It continued playing until I unlocked it and closed the tab.

Is this behavior normal? How can I avoid this? Has anyone encountered something similar?

You’re not crazy. The same exact thing just happened to me updating to 10.15.6. I thought I was going crazy. I was able to stop the Chrome tab playing audio with the pause button on the Touch Bar.
That was the most buck wild thing I’ve ever seen a mac laptop do while updating the OS.


Apps won't sync to jailbroken device from iTunes My iPhone 5s is jailbroken. I want to add some apps to my iPhone from iTunes but all apps don't sync correctly and are dark on my iPhone:

You could try using AppSync to sync the apps, or just redownload them.


Did iMessage beta on Lion finally stop working recently? I tried to send a message using the iMessage beta that I installed on Lion ages ago. The message didn't send, and then I noticed the prompt looked like this:

I tried to exit iMessage and restart it, but it wouldn't let me log in with the following message after entering my Apple ID:

Did Apple finally forcibly disable iMessage on Lion? Are there any solutions to using iMessage for me now? (I know I could upgrade to Mountain Lion, but I'm curious if there are any alternatives.)

Yes, Apple did disable Messages beta for Lion users.  French blogger from Consomac found the following in the French strings of the beta:

source http://consomac.fr/news-1339-messages-pas-sur-lion.html

Although this is not the exact error that you are receiving, inevitably it will ask you to move to Mountain Lion now that it has been released.  I encourage the upgrade, and if this problem recurs after you upgrade, try moving ~/Library/Preferences/com.apple.imservice.iMessage.plist to the desktop and restarting your computer.  You can If this does not work, move it back and edit your question accordingly.


Play music on iPhone via a mixer with wireless connection I want to play musi from my iPhone on a sound system but connected to the mixer wirelessly.

What interface an I get to plug into the mixer that would receive the music output. Looking at distance of about 25 yards and no wi fi hotspot available.

Or can I remotely control An iPad or Mac hard wired to the mixer wirelessly with an iPhone.

Thanks

You can control iTunes on a Mac or PC easily from an iPhone, using Remote which I think would be a lot more reliable than trying to establish a solid bluetooth/wifi connection to stream music to an audience who may not appreciate the occasional silence if the connection goes down ;)

Use it with a running playlist & even if you temporarily lose connection from the remote, at least it will never go quiet.


How to disable composite keys on Mac OS X I've got my mac two months ago and there is a problem that kinda bugs me to death. It is related to input languages and composite characters (those made up from more than one character, for example in Bulgarian Phonetic layout, the characters 'a(cyrillic a) produce ђ ).

I'm looking for a way to disable this behavior as I almost never (let's say never had to use them) and it gets in the way when I need to type ' followed by some other character - for example when I try to write python comments and I'm in Bulgarian Phonetic, when i type 3 ''' and then press enter for next line, a fourth ' is added and I have to delete it and press enter again.

Any ideas on how to disable this behavior. I couldn't find anything on the interwebs, but I believe it's because I can't formulate my search query right, as I don't even know how this feature is called.

Composite keys are bound to the 'Input Source' of your mac.

In your 'System Preferences', in 'Language & Text' you will see the option 'Input Source'.

If you have selected 'U.S. International - PC' for example, you will have the dead key problem. But if you change that to ordinary 'U.S.' you are fine and dead keys won't be a problem any longer.


Restore gmail messages to mail.app after TimeMachine restore I have a dozen different email accounts for different roles, all of which I interact with through mail.app.  I had a hard drive disaster, and restored from TimeMachine.  It did an impressive job of restoring my complex email structure for backed up email, and of course new emails coming in are fine.  But I am missing the month (urgh) of emails between the most recent backup and the restore.  They are still on gmail (some POP and some IMAP accounts).  How do I mark them as not already downloaded, so that they'll be retrieved from gmail?

For the mailbox in question, in the Mail.app, go to Mailbox (top menu), and then select Rebuild. You may need to relaunch the app for the older messages to be downloaded.


Lookup the dictionary with wildcards Since wildcards aren't recognized by the GUI, is there another way?

From the command line you can use look which looks for the string as a prefix of a word in the file- /usr/share/dict/words.

look ent

Right click the word in the Terminal window and select Look Up "....." menu or you can grep /usr/share/dict/words using regular expressions or extended regular expressions. Such as:

grep 'hello$' /usr/share/dict/words


How can I hide an existing user - El Cap I found commands about how to create a user that is hidden,
sudo dscl . create /Users/USERNAME IsHidden 1

but how can I hide an existing user?

The command sudo dscl . create /Users/username IsHidden 1 doesn't really create a full-fledged user. The user misses an UID and a PGID and some more attributes.

Instead it creates a "rump user" with a new Native Attribut Type: IsHidden with the value 1.

You can use the very same command for any existing user and add the IsHidden attribute with the values 0|1 though and after a restart the user account will be hidden in the login screen as well as in fast user switching (and in the System Preferences -> Users & Groups) if the value is set to 1.

Users with an UID ≤ 500 are hidden by default!


Appstore multiple update of the same application When I open up the AppStore, under updates, the application thinks that I need to update the same application several times. In this case Command Line Tools is listed several times in a row. How do I remove these multiple entries from the app store.

The log of your updates are available in:

~/Library/Application Support/App Store/updatejournal.plist

The simple solution is to clear the update logs by deleting the mentioned file.

Here is the guide to remove duplicate if you want to keep the update logs.

Open Terminal.
Convert the updatejournal.plist by entering this line plutil -convert xml1 then drag the updatejournal.plist from Finder into Terminal to expand the path, then press Return. Mine is the following:

plutil -convert xml1 ~/Library/Application\ Support/App\ Store/updatejournal.plist

Open ~/Library/Application\ Support/App\ Store/updatejournal.plist with your favorite text editor (TextEdit works fine).
Find the duplicate update logs. For example, mine is Command Line Tools (OS X 10.10). The point is to delete that entry which is inside the scope of <dict>. So you should delete the content between <dict> and </dict>. Here is line I need to delete. Save the file.

<dict>
    <key>__isSoftwareUpdate</key>
    <true/>
    <key>installDate</key>
    <date>2014-10-17T09:55:17Z</date>
    <key>productKey</key>
    <string>031-08844</string>
    <key>release-notes</key>
    <string>Command Line Developer Tools for OS X 10.10</string>
    <key>title</key>
    <string>Command Line Tools (OS X 10.10)</string>
    <key>version</key>
    <string>6.1</string>
</dict>

Convert the file back to binary1 by entering this line plutil -convert binary1 and drag the updatejournal.plist from Finder, and press Return. Here is mine in Terminal:

plutil -convert binary1 ~/Library/Application\ Support/App\ Store/updatejournal.plist

Open Mac App Store and refresh the Updates section. The duplicate line should disappear. Remember to only delete one entry of duplicate file. Imagine that plist as a spreadsheet with duplicate lines. Just delete one.

Feel free to leave question in comment if the tutorial is vague.


How to get iWork and iLife after upgrading to Yosemite from Mavericks? I bought a mid-2014 MBP Retina (activated on 30/09/2014) from a friend and did a re-installation of Mavericks, then upgraded to Yosemite right after the re-installation (without associating the mac to my Apple account. I only did that after upgrading to Yosemite.)

Now I realise that I cannot get the iWork and iLife apps for free (I should have associated the mac to my Apple account and use it to get iWork and iLife before upgrading, right?).

Is there anyway to get that apps without re-install everything ?

Thank you in advance for your help.

It is not about iCloud account but about Mac Apps store logged in account and upgrading said apps under it.

If you have iLife and iWork trials installed under Mavericks you will get them associated to your Apple ID logged into App Store. Can't say for sure but maybe you have to update them for this. Don't have to download them all the way though when they started updating.

And no there is no way to do it except having Mavericks. You might use another Mac with Mavericks for this (provided it doesn't have iLife and iWork already installed of course) or you might install Mavericks on your Mac — you can create a temporal partition for this, you can use external drive, USB or even SD card for this too.


How to Properly Uninstall Brother Twain Drivers in OS X 10.6 I recently had a situation where I wanted to uninstall a Brother TWAIN driver and rollback to an earlier version on my MBP (OS X 10.6.8). I found instructions on the Brother web site and followed them to the letter. However, I was unable to reinstall the older version (freshly downloaded from the Brother web site) - the installer provided a message indicating that a newer driver was currently installed on my system.

I ended up manually reinstalling the older driver by going into the DMG and extracting the files.

Questions

Are there any other locations that I should have looked to remove files from the newer Brother TWAIN install?
Are the Brother uninstall instructions complete?

To answer both questions at once, it seems that the Brother instructions only cover system level files.  This will not remove any files that you as a user created or installed.  I would go through the instructions again, then repeat the instructions, but for every location where it says "Macintosh HD > Library > x", I would also check at "Macintosh HD >  Users > YourUsername > Library > x".

It is also possible, depending on what version of OS (I see that you are rolling back to 10.6.8 - does that mean you were on 10.7?) that they are system installed.  I wouldn't recommend removing anything from your system folder, but it may be finding the drivers under "Macintosh HD > System > Library".


App store ranking - effect of downloads from multiple countries If I have an app in the app store, it seems to be that the general consensus is

  Higher Downloads = Higher Rank

However, if my app is downloaded 500 times in Australia, will that affect my US ranking? Or are the app stores completely country-independent?

Not sure if this is the correct place to ask this kind of question, you should try the Apple Dev Fora (http://devforums.apple.com). Beside this, no-one will be able to answer this question 100% sure except Apple engineers, however, we can assume Apple is isolation the stats per store, meaning lot of downloads wont affect the rankings in other stores.


iTunes on iMac won't start up after upgrade (error -10699) Yesterday I updated iTunes in my iMac running OS X 10.10.3. According to the information in App Store, the new iTunes version is 12.1.2.

Since then iTunes won't start up. If I click on it, there is no response.

I figured that there is probably a known problem with the upgrade, and that this would be fixed in due course. However, I've been monitoring discussions, and there does not seem to be anything else who is having this problem.

Some research I did on how to solve this problem was to trash the iTunes preferences, and to download and re-install iTunes: I did both, but it still won't start up.

Nothing is logged on any error logs as far as I can see. I did a "tail -f /var/log/system.log" in Terminal App and then attempted to start iTunes, no messages were displayed.

When I try and open iTunes from terminal ("open -a iTunes"), I get a message:
"LSOpenURLsWithRole() failed for the application /Applications/iTunes.app with error -10699."

Open With Role sounds as if there might be a permissions problem, I've repaired permissions with Disk Utility, and I've also tried starting iTunes from the command line using sudo, but no luck.

At this stage I've run out of ideas. Anybody else have an idea what I could try?

I had the same problem and was able to solve it by deleting iTunes and reinstalling.

The Finder tries quite hard to stop you from deleting iTunes; instead you can open Terminal.app and 'sudo rm -rf /Applications/iTunes.app'. You can download the replacement copy of iTunes from https://www.apple.com/itunes/download/


How to set a date visibility Catalina OS? Now I see a date on the top bar in such format

But I would like to change it that I can see also a date, like this(for example`

Fri 10.11.19 10:13

How to do it?

Assuming it hasn't suddenly changed in Catalina after being the same for years…

System Prefs > Date & Time > Clock

Check Show date

As far as I'm aware, there is no option to change the displayed date format. It will use your Language & Region prefs for that, but adjusting date formats in there does not affect the clock display.


How to install Anaconda python for multiple or all users? How to install https://www.anaconda.com/products/individual not just for Administrator?
I was trying to install it from GUI but installation for all users was disabled:

If you want to make Anaconda available to all Users from the Individual Edition, using the, e.g. Anaconda3-2020.07-MacOSX-x86_64.pkg package from the download link at the bottom of the linked web page, e.g. 64-Bit Graphical Installer (462 MB), then do the following:
From an Admin account...

Download e.g.: Anaconda3-2020.07-MacOSX-x86_64.pkg
Install it to: /Users/Shared

Select Install on a specific disk... and navigate to /Users/Shared on the Macintosh HD.

After the GUI install...

For the User doing the original install of Anaconda, if bash is your default shell you should be set because the GUI installer sets up what's necessary in ~/.bash_profile, however, if zsh is your default shell, run the following commands1 in Terminal:

Note: For each additional User, steps 3 thru 5 are required regardless of your default shell.

1 For each additional User setting up, if bash is your default shell just use conda init in step 3.
source /Users/Shared/anaconda3/bin/activate
conda init zsh

For zsh the ~/.zshrc file is created or written to in this step.

Close the current Terminal window and open another.

To control whether or not each shell session has the base environment activated or not, run conda config --set auto_activate_base False or True. To run conda from anywhere without having the base environment activated by default, use conda config --set auto_activate_base False. This only works if you have run conda init or conda init zsh first.

With that done, each User only has to run steps 3 thru 5 from Terminal when logged into their account to have access to what was installed by the Admin from the original GUI install of Anaconda.


Mail - Deleting/Hiding Exchange mailbox's (e.g. RSS Feeds) We're running Exchange 2010 and I have access the server if I can make changes there.

Basically is there a way to hide or delete the RSS Feeds folder that shows up on the Mac Mail app?

When I try to delete it I get:

The mailbox “RSS Feeds” could not be deleted.
The server returned the error: Distinguished folders cannot be deleted.

You can't get rid of it from Outlook 2013 (Windows) either.

Any ideas?

I was hoping you could disable these folders from the Exchange backend but I haven't found anything yet.

There is a way to removed the RSS Feeds folder from Outlook 2013 using MFCMAPI
http://mfcmapi.codeplex.com/
there's a youtube demo here as well
https://www.youtube.com/watch?v=-g45GbCOjx0
Only difference with Outlook 2013 compared to Outlook 2010 in video was that the RSS folder was found in the the IPM_Subtree subfolder.


My 2TB external drive keeps disappearing every time I boot my Mac I have an external LaCie Porsche 9223 2TB drive connected to my Macbook Pro 15 (2015) via USB3. After I converted it to APFS after upgrading to macOS High Sierra, it keeps disappearing randomly from Finder/Disk Utility and the "/Volumes" folder, and nearly every time I boot my Mac.

This is what puzzles me though:

If I clean/remove the Dyld shared cache via Onyx, the drive shows up momentarily on the desktop/Finder sidebar with (seemingly) no problems whatsoever. Disk Utility reports that the disk is OK. The next time I reboot: poof, gone .

Does anyone have a clue what's going on?
And why the "dyld shared cache" cleanup is like a magician's reappearing trick every single time? If I only knew why that works, I would probably/most likely find a way to prevent it from happening again.

Best regards,

Andreas

Macbook Pro (2015), macOS High Sierra 10.13.2, 16gb RAM, 500gb SSD

After upgrading to High Sierra, I had the same issue with my LaCie shared not listed in shared devices, coupled with SMB hanging without connecting to remote servers.

The SMB issue was solved by changing the SMB version to v2 in the /etc/nsmb.conf configuration file and rebooting the Mac as recommended in this post on SMB share deadlock. After the reboot with the new /etc/nsmb.conf, shared devices were again correctly listed in the sidebar including my LaCie shared disk, so I surmise both issues are linked.

The /etc/nsmb.conf file I use is:

$ cat /etc/nsmb.conf
streams=yes
soft=yes
signing_required=no
protocol_vers_map=2
file_ids_off=yes


CPU System agent core (TC0E/TC0F) running very high When my MBP (Retina, 13", Early 2015, identifier MacBookPro12,1) is under load, could either be CPU load or "bus-load", ie wifi, usb, webcam etc the CPU System Agent Core-sensor shows a very high temperature. The SMC-key is either TC0E or TC0F (ie Tango Charlie Zero Echo / Foxtrot). With very high temperature I mean 90C+, and I start to get bus errors here.

I believe this is either due to faulty SMC cooling "instructions" or bad application of coolant paste. I'm leaning towards bad application of coolant paste.

Is there any way I could easily check this? I guess I would void warranty by actually opening the MBP?

If you want to test your temperatures compared to mine:

-- At first, get homebrew, see instructions at http://brew.sh
-- after installing run
> brew cask install istat-menus
-- thereafter
-- scan for all sensors
> istats -scan
-- add the two which go high for me to default set
> istats add TC0E
> istats add TC0F
-- check default + added sensors
> istats

I would do a SMC reset (google on apple)
In addition to iStat, i have Macs Fan Control.
just use iStat to DISPLAY fan speed and CPU gfx core temp
Use Macs Fan Control, MFC, to control fan speed.  By default, my mbp's fan will not come on, and often doesn't even when way beyond 45C!
in MFC drop down menu... Right Side - Sensor-based... Change control...

Sensor-based value: GPU PECI
Temp that fan speed will start to increase from: 30C - 80C
OK to confirm change

I believe MFC is a linear fan curve, as temp increases, fan speed will also go up.  I prefer it this way.  Lost my last mbp to lousy fan control, not happening this time.
my MFC just shows fan icon in menu bar, but no fan speed or temp info.
Remember in MFC's preference... set it to autostart

Im out and about quite a bit with my mbp.  I use a hard shell case from iPearl (search on Amazon... our model is A1502).  Its got little legs I can prop up the rear of my mbp, to keep it cooler.  Fits well, no issues here, I am typing on it right now.

mbp 13" retina 12,1 blah blah,   ~1900 rpm, 35C

As far as CPU System agent core on my mbp, iStat will report it to be 0 at times, then it'll resume back to normal in a sec or two.  Let me know if u figure out that one.  thx.


Restoring deleted iTunes 12 user music libraries After having updated iTunes, my entire music library disappeared. What can I do to restore it?

When iTunes updated, whether automatically or under your permission, it replaced its data which contained information on getting your music. None of the music that you have downloaded via iTunes, or even added into iTunes from a CD won't appear. What only appears is links to stream anything that has been purchased from iTunes, even though it may still exist on your computer.

To fix this, do the following:

Navigate to your computer's music folder.

This is normally the folder called "Music". On Mac OS X computers, you can type this in Terminal:

open music

This should open your music folder.

Navigate to the iTunes folder

In the music folder, you should see an "iTunes" folder, which has a few files. Locate the iTunes Library.itl file. Rename it to iTunes Library (corrupt).itl.

Locate the missing user library

Next, there should be a folder called Previous iTunes Libraries. Inside this folder, should be a few files, which are called iTunes Library followed by the date. Choose the latest file (The order is Year-Month-Day. e.g. 2015-08-18 for August 18th 2015). Copy the file.

Place the user library back to its proper spot

Now that you've copied the iTunes library that holds all the information about your real music libraries, we need to place it back where it belongs. Go back to the folder where you renamed a file to iTunes Library (corrupt).itl. Paste the copied library here, and rename it to iTunes Library.itl.

Restart iTunes and Voila!

Restart iTunes, and your original music libraries should be there! Happy Listening!


Thunderbolt ethernet adapter ist not appearing in netwoks tab I have bought an Apple Thunderbolt Ethernet Adapter and can't seem to get it to work.

It simply does not appear in the Network section of System preferences, even though the System Information dialog shows it is connected.

I have el capitan and a retina macbook pro.

EDIT: I took it to the store and they confirmed it works fine. So it seems to be a software issue.

iPhone 5 says "disabled, connect to iTunes" but iTunes says it "can't connect because of an unexpected error" I rebooted it but it still says "iPhone is disabled, connect to iTunes" even though I don't have a password on it anymore because I rebooted it. When I try to connect it to iTunes it says "Can't connect to iPhone because of an unexpected error.

Focus on iTunes first. You need a working version of iTunes and can test with another phone if you aren’t sure your iTunes is ready to restore any phone and not just the one that’s disabled.

https://support.apple.com/en-us/HT201263

The disabled unlock will be your next hurdle, but get iTunes working unless you want to take the phone to another computer for erasing and determining the unlock status.

Firefox 28 search is easily interruptible When I search on a Firefox page (command-F) the search interrupts itself all the time.

E.g., I start typing "backtick" and, right before I hit t, back disappears and I am now searching just for t.

On the other hand, sometimes the search prompt in a tab persists: I go to another tab, and, when I get back to this one, the search prompt is still active with the old text in it.

This behavior started when I upgraded to FF28 a couple of days ago, however, I seem to recall that I experienced this sort of annoyance some time in the past.

Any idea what might be causing this?

Removing the extension "fast video download (with search menu)" solved the problem.


Disable alert: "Cellular data disabled for [app]" The above alert pops up every time I open an app whose access to cellular data I've turned off. This adds an unnecessary step every time I launch one of these apps. My feeling is, "Who cares if cellular data is disabled for Photos? I just want to see my damn photos." This happens with 3rd party and native apps alike. I first noticed the issue in iOS 7 and am seeing it again in iOS 8. Is there a way to turn off these alerts?

Sadly, there's no way to stop seeing that alert every time you open the app from the cellular data network.

Every time the app tries to connect to the Internet, then you'll see that alert.

In fact, there is one way you'll probably won't like, but just in case... If you put your phone on airplane mode, then you won't see that message (though you'll see the annoying "no data connection" if you perform any activity that asks for connection anyway).


How can I make Vuze work with Lion? (It cannot transfer any data) I'm having a bit of trouble with Vuze after installing 10.7 (and the JRE.)
Vuze can connect to seeds and peers, but no data will transfer! That makes it a bit useless.

So far I have tried:

Running Vuze as root
Switching to the 32 bit JRE
Trying the 4.2.0.5 Vuze beta
Attempting to run it using the Java 1.7 OpenJRE (wouldn't launch.)
Attempting to install the Leopard Java 1.5 JRE (wouldn't install.)

Any ideas would be greatly appreciated!

Essentially, Mac OSX Lion has issues with java.

I'm pretty sure this is a Java issue. Apple's support for Java in 10.7 is severely lacking. I had to download (wasn't installed with 10.7) Java 1.6.0_24 using Apple's ADC (developer) site.

Installed Java and restarted my Mac. Launched Vuze and I was able to receive incoming traffic. Paused the download and it all ended there. Vuze now keeps crashing and I'm still not receiving any incoming traffic again.

Is there a tool that identifies which NSControl is under the cursor? I'm looking for a tool that could help me understand the layout of a closed source Mac OS applications in term of Cocoa controls. I saw this for in Firefox with the 'inspect' feature (for HTML/CSS); I don't expect it to work for every application because of the variety of programming languages and custom classes.

You can use a usability tool from Apple to see the structure of most user interfaces; try the Apple developer tool Accessibility Inspector. I believe it will do what you need.

The latest Xcode download may not include this tool as standard. You may need to download an additional package to find this tool.


Does my MacBook Pro (2016) supports CUDA? I have MacBook Pro with maximum specifications and mostly I use for video rendering stuff. The performance is great but I found that I could make video rendering a lot faster by enabling CUDA.

I explore some sites and found that CUDA works with NVidia Graphics and there are many similar questions but there is a slight difference in model (like Graphic card).

So, can anyone please confirm:

if my MACBook supports CUDA?
if not, what is the best alternative?

MacBook Info:

Model: MacBook Pro (15-inch, 2016)
Graphic:

Intel HD Graphics 530 (1536MB)
AMD Radeon Pro 460 (4096MB)

PS: Many people recommends to check GPU support on this link: https://developer.nvidia.com/cuda-gpus As it's on NVidia website so I am not sure if they are listing all supported OR just NVidia all supported gpus.

CUDA is a NVIDIA technology and only exists on NVIDIA graphics cards. Your MacBook Pro has an AMD graphics card and therefore doesn't support CUDA.


Why are executables called DMG (disk image) files? I am not experienced with OSX but I have been using it recently.

It seems to me the equivalent of an .exe (executable) in Windows is a .dmg (disk image) in OSX.

And you don't install it, you mount it.

I am trying to wrap my head around these terms, why do they call it this?

.dmg files are disk images, similar to an .iso file.

You can think of them like a virtual CD. You put it into the CD drive (mount it), and its contents appear on your computer.

When used for software downloads, they are simply a way to bundle up files, like in a ZIP archive. Their advantage is that it's possible to customize the design (e.g. Finder window background and icon positions, see example below).

The actual program is in a special bundle or package directory with the usually invisible extension .app. It contains an application's resources, like image files, and the actual binary (the ".exe equivalent") that is executed when you start the program. If you want to compare it to a Windows equivalent, the closest would probably be the folder in C:\Program files\ created by a program's installer.

To install such an application from a disk image, you drag and drop it to your hard drive, e.g. the Applications directory. That's what a lot of disk images try to convey in their disk image design: You grab the application, Adium in this case, and drag it onto the Applications folder:


Using zgrep on a remote drive eats space on my local Mac I connect to a remote drive via WebDAV protocol, whereon I have a folder full of about 143 .tar.gz files containing data dumps, whereamong I'm trying to find my email.
Herefor, I use this command:
zgrep -a "my@email.com" /Volumes/storage.address.name/home/folder/Collection\ \#2-\#5\ \&\ Antipublic/*

Once the command is running, I can see my free space on my local MacBook, wherefrom I run the above mentioned command, disappear swiftly, like 0,5 GB per minute. If I let the command run, I would totally run out of space.
Could someone please tell me why is this happening or how to prevent it?

Once the command is running, I can see my free space on my local MacBook...disappear swiftly...
Could someone please tell me why is this happening or how to prevent it?

Operating Locally while connected remotely
The command is acting upon those files as if they were local, even when they are not.  *nix systems have this wonderful feature where you can mount almost anything as if it were a local file/directory.  This "feature" is where you're running into this problem.
To operate on the file, it has to "download" it from the remote, hold it in memory and if necessary, resort to swap space.  If it needs to unzip it (bzip, gzip, compress, etc.) it will likely utilize a temporary file (i.e. mktemp).  Since your command is operating locally, all the resources it will utilize will be local as well - it doesn't know to use your remote for temp space.
You can do a simple experiment to show how this works - move a file from one remote directory to another. Using a simple mount on a NAS (/Volumes/NAS/) if you try to move /Volumes/NAS/folder1/* to /Volumes/NAS/folder2/, this simple operation will need to "download" the files to local machine, then upload them to the destination folder.  However, if you login directly to the server and issue the move command there - for example, mv /home/username/folder1/* /home/username/folder2, it will happen almost instantly.
In your case, it has to extract a number of files from each of those .tar.gz files, download them, store them in a temp location, then load it to memory for as the ASCII text is searched for.
Cleaning up Temp files...
An important consideration to keep in mind is that temp files are not cleaned up until the process has completed or terminated abnormally; if the developer was good about it.  If not, those temp files will be cleared out upon reboot.
If you have 200GB of files to search and a MacBook Air with 128GB or 256GB of storage, you will run out of space very quickly filling it up with nothing but temp files.
How to prevent it
Do you operation on the server (remote machine) itself.  Instead of mounting the remote file/directory locally and operating on it locally, connect via SSH (for example) and issue your command on the remote itself.
Can you specify a different location for the temp directory like the remote?
Technically yes.  For example, gzip uses /tmp and you can set your environment variable to a remote temporary directory (i.e. /Volumes/NAS/tmp).  The problem is, you're still operating on the file locally, so it would "download" the file, and then while extracting them, "upload" all the extracted bits to the remote.


Certain .MOV video file will not play audio in VLC for iOS (iPad) I have tried 2 different iPads. Both have about 7 or 8 other .MOV files (from the same folder) that play just fine. However, this single .MOV file just will not output any audio. It plays fine on the PC (Windows 7). Should I just to convert it to a different video format or what? Thanks.

I was able to convert the .MOV file to a .MP4 file with Handbrake and audio is working now.


Run MacBook Pro with lid closed Is there a simple setting to allow a MacBook to continue running with the lid shut?  All signs that I found pointed to no supposedly due to concerns about overheating, but when docked, a MBP is able to be used if the monitor and keyboard are plugged in.

My use case would be running a terminal command that takes awhile, leaving my desk, locking my account, and closing the lid to keep nosy people out.

After looking a little further, I found what I was looking for on this page: How can I prevent my Macbook Pro 2011 from going to sleep when I close the lid?

Time Machine alternatives to clone one mac book to another Due to nature of how Time Machine works, backing up or restoring large backups is incredibly slow, even with a USB disk instead of a network attached backup unit.

As a result, I am looking for a faster alternative to backup one mac book pro and restore the data on another, in the same manner the Time Machine does.

Can you suggest any tools/apps to achieve this?

Two of the most popular and reliable backup options outside of using Time Machine are:

Carbon Copy Cloner
SuperDuper!

Keep in mind that using something new is still going to take time to do, as you're going to have to clone your data totally from scratch anyway.

So, if you already have a current Time Machine backup, then using that to transfer all your files is certainly a good option. Many people just set it up to do this overnight, so how long it takes isn't really an issue.

However, if you have other reasons for not wanting to use Time Machine, then using Carbon Copy Cloner or SuperDuper! are excellent choices.


Is encrypting then deleting the same as securely erasing? So, recent versions of macOS no longer offer the option to Empty Trash Securely. From what I am reading here and here it seems the general consensus is that it is now best to encrypt files and then delete them.

However, if I create an encrypted disk image and move the files in there, it is using different blocks on the drive... so it does not zero out the blocks on the drive where the data was stored, and we're back where we started.

I've read comments from people saying deleted data is difficult to recover from an SSD anyway, so don't worry about it. Well even if that is true, what if you have a Fusion Drive and you don't even know which part of the drive the data in question resides in?

I'm not finding a clear answer on what the best way is to securely delete at present, which is surprising since it's a pretty common measure when transferring ownership of a computer, etc. Can someone please enlighten me:

Is encrypting then deleting effectively the same as securely erasing?
How can existing data be encrypted (rather than copied into an encrypted .dmg)?

To answer your question 1: You often see encryption mentioned when you speak of securely deleting the contents of a computer.

The reasoning behind this is that if you for example fully encrypt the disk drive on your computer (i.e. use the built-in File Vault encryption as an example) - then no one can access the contents of the drive without the password.

If you then encrypt the drive with a long, random password and immediately forget that password - then you have effectively deleted the data. If you don't know the password, and it is not written down anywhere - noone can access the data.

The caveats are ofcourse if your password is so bad that it can be guessed, or there's a bug in the encryption routines that makes it possible to recover data without the password.

Remember that:

(a) You must not store or remember the password anywhere

(b) You must not add a password hint or anything that makes it possible to guess the password

(c) You should throw away any recovery keys or similar, and make sure you're not storing a copy of passwords/recovery key on iCloud

(d) The password should be sufficiently strong (i.e. long and random)

To answer your question 2: If you have already stored the data unencrypted, you're out of luck. Just copying them into an encrypted image or anything like that won't replace the data on disk. Instead you'll be making an encrypted copy of your data - there's no guarantee that the disk will really delete the non-encrypted data.


Will updating my MacBook Pro to OSX Yosemite delete/ruin my current files on desktop I'm currently working on an Xcode project that I have on my desktop. I'm currently using OSX version 10.9.5. If I update my mac to OSX Yosemite 10.10.3, will this delete all my projects/files with Xcode 6.1 that I have on desktop that i'm working on?

It probably won't, but just to be safe, it never hurts to take a backup! Take a Time Machine backup of your hard drive, and then upgrade. Worst-case scenario, you lose your Xcode files, in which case you can just wipe your hard drive and restore from the backup.


I uninstalled Dropbox but still have .dropbox listed when I do ls -a. Why? I have uninstalled Dropbox from my Applications on OS X but it is still showing as .dropbox in my home directory.  Why is that please?

Removing Dropbox doesn't delete its preferences/cache/etc, which is stored in ~/.dropbox. You can delete this yourself.


What can be done to troubleshoot OS X Wi-Fi self-assigning ip address of 169.xxxxxxxxx when other clients connect? This is incredibly frustrating; I have a new airport extreme and its been working fine for about a month but now it has stopped working. my two MacBooks and dell Inspiron tower cannot connect to the Internet. The weird thing is that my iPhone can. On the MacBooks, the network settings say 'wifi has the self assigned ip address 169.xxx.xxx.xxx and will not be able to connect to the Internet.' why can my iPhone connect but not the computers?

Two avenues can solve this problem:

Find and disable whatever firewall is intercepting the DHCP return traffic since your Mac needs to see what IP address the route is assigning it. When it doesn't get a response, eventually the DHCP request times out and your OS self-assignes an IP in 169 land.
Inspect the network traffic or the router logs to see if and why the Mac DHCP broadcast packet is being ignored. The router could be out of IP addresses, not allowing that MAC address or just an odd network condition is preventing the router from seeing the OS X request for a DHCP address.


Export compressed videos from quicktime screencast / screenrecording I create quite a few screencasts to show colleagues how to do more complex tasks and share bugs that i am finding.

For this I use the File > Screenrecording feature in quicktime.

Once im done recording i save the video to the relevant location, but the exported videos are often 20-30mb even for a relatively short one.

What i tend to do at the moment is then run these videos through Handbrake (open source video compressing software) which gets the videos down to a much more manageable (email-able) size, usually between 2-5mb.

The only issue with this is its another step, and involves opening other software letting it process etc.

Is there a built in export / compression tool in quicktime where i can export smaller videos ?

The easy way is to export instead of save. You can go to File → Export → iPad, iPhone, iPod Touch & Apple TV...

Then pick an option.

iPod touch & iPhone 3GS is the one that give you the smaller file size with a resolution of 640×400.

For the screenshot I test it with a video of 6.9 MB.


Can I sync my iPhone with the new Apple Photos app via iTunes / without iCloud? I would like to sync my photos from my Mac to my iPhone using the new Apple Photos app without using iCloud, like it was possible with the old iPhoto app and iTunes on the Mac.

Yes, it's possible with iTunes 12.1.2 which was released today.


How to duplicate the content of a MiniDV to a DVD? I'd like to save the content of some miniDV tapes to DVDs. I can use iMovie to do it, but iMovie creates a lot of video files and sort them by date. It will be a titan job to reorder them by hand and burn a DVD after that.

Is there a way to ask iMovie to just create 1 giant clip with the content of a tape? or any other way to sort the clips as they stands on the tape (import order will be fine)

Or, eventually, Is there another app that does the job?

There are a few ways to get a single large DV file imported from tape, depending on whether your constraint is budget or time:

1) QuickTime Pro 7 has a recording mode that can see DV devices. Yes, Apple still charges $29.99 for it, but the interface is simple and lets you record a long, single file. Just make sure the capture format in the app's preferences is set to 'Device Native' or something along those lines (I believe it wants to transcode to MPEG-4 by default).

2) WhackedTV was a free sample application provided by Apple to developers to demonstrate video capture frameworks. The app seems to be gone from Apple's site but a third-party mirror is available. This app lets you add a DV video/audio source, configure its capture format, and record as long as you need to. I still use this app on a regular basis.

3) A final option is to script the standard QuickTime 7 player via AppleScript to open a video capture window, which it will allow you to do even if you haven't purchased Pro. Unfortunately, I don't have the original source code for this script, so you would have to open up AppleScript Editor and QT7's dictionary and work it out through trial and error.

Any of these recording approaches will yield a .dv file (or a DV file in a .mov container), either of which can be taken in by iDVD, a simpler DVD app like Burn, or by Handbrake if you wish to transcode to MPEG-4/H.264.


How do I automate a backup of new MobileMe calendar data The new MobileMe iCal data lives in the cloud, and the data on your computer is actually a cache. This support article from Apple explains how to backup calendar data by exporting to an .ics file. I would like to automate that process via AppleScript, Automator or any other method (paid software is fine).

The sticking point with AppleScript is selecting the calendar on the left hand column. In Automator I don't think the available actions support this level of automation.

Automator does support selecting a Calendar. Using the Filter or Find actions, you can Find (Calendar) Where: and then (Title) (Contains): ____


How to set up Reply from email on Apple Mail? I'm experiencing trouble with my Apple Mail app. I've multiple mail accounts configured on it and when I'm replying from any of them, app displays correct value in From field. But just after I send it, in the Sent catalogue appears absolute different (other account's) From email address in that message. And people always get my mail from that one account no matter what I set in the From field when writing. Do you have any ideas what is wrong, what should I do? By the way, I'm using Yosemite OS.

Solving this could actually be as simple as changing one of the preferences:

Apple mail > preferences > composing

..check if "Send new messages from" is set to "Account of selected mailbox"

Are 17″ MacBook Pro for sale by Apple? I have a 2010 Macbook Pro 17″

It does not have a Thunderbolt port. I believe about a year ago Apple released a 17" that had a thunderbolt port. I was thinking about upgrading to a newer 17" model but there is now 17" macbooks in the Apple Store. I want a new Mac, not anything from the refurbished section.

I checked MacRumors and there is no news about a newer 17". I also heard that a 17" with retina display seemed pretty impossible - because of the price / technology limitations etc.

Does Apple still sell a 17 inch portable Mac?

Here's your answer:
Apple discontinues 17 inch MacBook Pro

From the site:

  "But if you’re looking for a reason why Apple offed the 17-inch now, you need go no further than the 15-inch Retina display MacBook Pro. Not only does it offer the most cutting edge technology of any Apple laptop to date, but its 2880-by-1800 pixel display outstrips the 17-inch’s 1920-by-1200 resolution with room to spare. Add in the fact that the new MacBook Pro is thinner and lighter—to the tune of more than 2 pounds—and it seems pretty clear that the Retina display model is the new target for what a powerhouse portable should be."


TCP Congestion Control Algorithm of OSX10.7 How can I find out which algorithm OSX10.7 uses (NewReno, SACK, Tahoe...) and if possible, how can I change it?

This Stack Overflow question should help: How to load a different congestion control algorithm in Mac OS X?

  The LEDBAT congestion control algorithm is built into OSX Lion
  (10.7.X) and does not need to be compiled separately. I don't think it
  would be possible to use LEDBAT in an earlier version of OSX without
  alot of work. LEDBAT provides for 'background' transfers and may be
  selected on a socket by setting the following socket option -
  setsocketopt(sock, SOL_SOCKET, O_TRAFFIC_CLASS, SO_TC_BK,
  sizeof(int)). It also seems that the socket's traffic class may
  affected by the DSCP value in the IP header.

  Additionally OSX has had the facility to load kernel modules for other
  network protocols for some time using their Network Kernel Extensions
  (NKE) - for example there is an NKE module that has been developed for
  the SCTP protocol.

Alternatively, another related question might be useful: How do you set the TCP congestion control algorithm on OS X?

  According to
  http://www.macgeekery.com/gspot/2006-03/mac_os_x_network_tuning_guide
  you can actually modify the algorthims used by Mac OS X by using the
  sysctl command, but you cannot use anything but the New Reno algorithm


Vertical green stripes when iMac starts to boot up An iMac has 5 green vertical bars/stripes that appear on the screen as soon the system starts booting.  The OS is Yosemite (10.10.?)  When I try to boot the computer normally, safe boot, or diagnostics the computer gets just beyond the Apple logo with progress bar and then restarts itself.  I can successfully boot into Single User Mode without the green bars appearing.

My first question is do you know of a fix/reason for the green vertical bars?

Second question:  Do you know of a way to create a backup of the drive or “Macintosh HD” volume while in Single User Mode?  It would be nice if the backup was bootable but not necessary.  I tried “asr” command but it had issues (“could not initialize Disk Arbitration…”) in single user mode.  Can some services be started so that “asr” works?

Thank you for any help

Vertical bars/strips are usually indicative of a display malfunction. If you are also having booting problems, it is more likely GPU failure. You should take the iMac to Apple soon as it likely requires servicing.

To backup your iMac, connect an empty hard drive with enough storage to back up your iMac, then go to System Preferences > Time Machine. Turn Time Machine on, and select the disk you just connected. Allow your Mac to backup before taking it to Apple.


Is there a way to kill an unresponsive applescript launched by an application without killing the application? I've got an AppleScript that I usually launch out of Quicksilver, but occasionally, the script hangs, never exiting. (I think it's waiting on a non-existent window to appear).

This results in Quicksilver being monopolized, waiting for the script to die off.

If this were a Windows box, there would be a "scripting host" process I could end to fix this, but I'm not sure if OS X has a similar process. Nothing jumps out at me in the process list.

Of course, I could just kill and restart Quicksilver, but I'm wondering if there's an explicit way to just kill a runaway applescript that's running in the context of another application?

It looks like the AppleScript is run within Quicksilver’s process (depending on how you run it). If that’s the case, you’d need to relaunch Quicksilver. If it’s not completely frozen, you can do this quickly with ⌃⌘Q.

It might also be possible to set some kind of timeout in the script to prevent it from hanging indefinitely.


Preferences/General - How do I get it to save in Lion? I don't want my apps to open previous windows.  When I go into Prefs/General and unclick "Restore windows when quitting...," and close preferences, it doesn't save it.  When I re-open Prefs/General, it's checked again.

I can't change the preferences in anything.  Safari keeps opening the same last two windows and when I go into Safari Preferences and change "New tabs open with:" to 'Home Page'; once I close and open up again, it's back to 'Top Sites.'

Need to reset permissions? Try the following:

Turn off computer
Reboot Mac into Recovery (press and hold Command+R when you hear the chimes until a screen loads)
Select "Disk Utility"

Select your "Macintosh HD" volume on the left and press "Repair Disk Permissions"

Once that has finished, reboot your computer


My iPhone 7 allows only one device to be connected to its hotspot at a time Model - iPhone 7
iOS version - 13.3
My iPhone 7 allows only one device to be connected to its wifi hotspot at a time,  whichever is the first device. Only very rarely it allows more than one device to be connected. And there isn't anything in the settings that can be tweaked. Google search also doesn't show anyone with this problem. I am at a loss as to why it is happening.
Edit: Updated to latest iOS 14.0, still unresolved

I use hotspot quite a bit and can report that this isn’t how the system is designed. I have many devices connect to one hotspot and am pretty certain I tested that back when I had your iPhone 7 hardware in the US so it should be easy to confirm it’s capable of multiple connections.
What was true in the past was carriers (for example Verizon and AT&T capped connections at 5) can establish these limits for most of their data plans.

How can carrier limit hot spot connections

Since your cellular carrier specifies whether you can use the hotspot or not, have you reached out to them to determine if they have enabled any restrictions or profiles relating to hotspot usage? In the US, all of the carriers I have seen don’t cause this to happen, so I’d hate to tell you to update / wipe your device and test with all content and settings erased if this is something the carrier controls.


Rename a music playlist from "Purchased" to actual album name on iPhone 6, iOS 9? I have a free music album from the iTunes store that shows in my iPhone playlist as "Purchased." I want to rename it to the album name.

Can I do that directly on the phone, or do I need iTunes? How do I do it?

If it makes a difference, then the album is U2 Songs of Innocence. You know, the album that everyone was upset about it because it suddenly appeared in your playlist, whether you wanted it or not.

You cannot rename 'Purchased' - that is where all your 'officially purchased from Apple' [whether you had to pay for it or not] music sits.

You are free to make a new playlist & copy any tracks you wish to it, exactly as you would for any playlist, on phone, pad or Mac.

How can I ask Siri to turn OFF Do Not Disturb mode? As from iOS 6, I can ask Siri something like "Don't Disturb Me", and it replies confirming that Do Not Disturb is activated.

However, I have not been able to deactivate Do Not Disturb mode by voice.

What verbiage should I use?

In the past, You could ask Siri that all you want, but she wasn’t programmed to toggle that switch for you.

Until now on iOS 12 - we now have sweet satisfaction in voice mastery over this toggle.


Is there any USB Network Adapter available for Mac that works with Big Sur? My MacBook 14's wifi sometimes doesn't connect with my router or my mobile hotspot. I bought a USB WiFi adapter but I couldn't find its drivers for macOS Big Sur 11.1.
I searched the internet but couldn't find any product that is compatible with macOS Big Sur 11.1. Does someone know if there area ny USB Wifi Adapters that are compatible with macOS 11.1?
Thanks

TPLink has many to choose from, eg.

Archer T3U Plus

The downside, is they don’t even sign their drivers or installer and force you to relax security on Catalina, but they seem to have the newest drivers even though they haven’t said explicitly they support Big Sur. Be sure you can return them until they support Big Sur officially if you are on a tight budget or can’t pre-test them.


Are deletions in Google contacts synchronized to and from the Address Book? If I select the option to sync my Address Book to Google:

and I delete a contact on the Mac Address Book (or from my iPhone), is the contact automatically deleted in Gmail?

And what about vice versa?

Yes, that is what sync is all about :)

You can try export your Mac Address Book as a backup, and then try the setup and see it for your self.

You can however also do it the other way, by exporting your Google contacts if this is your main contacts, and then try a sync setup.
