Lost Windows Bootcamp boot entry after resizing the partition I have a 2011 iMac that I had used Bootcamp utility to install Windows 7 on. I got overzealous and tried to triple boot Windows, Mac and Linux on the iMac. I no longer need Linux on this iMac but the process corrupted my boot table and now I can't boot into Windows. If I press and hold 'alt/option' key after it reboots it doesn't show me the Windows bootcamp boot entry -- just Mac and Recovery drive.

However, in the file system, I still see all the files for Windows intact. So the file structure is still there, just the boot table entry is messed up somehow. I tried to 'repair' it but Bootcamp utility no longer gives me the optin of making a bootable Windows thumb drive using the Windows ISO that I have. It just asks to download some support software for Windows and that's it.

If this was Linux, I'd use something like 'boot repair' ISO or 'update-grub' to update the boot table but how do I repair the boot entry in Mac?

I have the Windows ISO available and I'm comfortable with command-line.

UPDATE: Details about the system

The optical drive on my system works. I was wondering if I could create a bootable thumb drive though. Bootcamp does not give me this option in the 2011 iMac but I was hoping to the edit the 'info.plist' in Bootcamp's contents folder to add my iMac model in there so that Bootcamp gives me the option of booting from thumb drive. This "patch" is described here: Bootcamp - No ISO Option

But is there any other simpler way to create a bootable thumb drive to install Windows on a Mac?

There are ways to create a bootable Windows installer thumb drive. The problem is you can not use this thumb drive with your computer. The software that searches the USB ports for bootable flash drives is part of the the firmware located on the main logic board. This firmware is not part of the OS X (macOS) operating system. Even though the firmware for the 2011 iMac can boot OS X (macOS) and certain Linux versions from a thumb drive, the Windows 7 installer can not be booted this way. The best option is to use original internal optical (DVD) drive. I would recommend a RW DVD which takes longer to burn, but is reusable.

If the Windows partition is intact, there are three main reasons you can not boot Windows. These reasons are listed below and apply to Mac computers which are booting Windows using the BIOS method.

The values in the partition tables are wrong. There are two partition
tables. The first is the legacy Master Boot Record (MBR) table and
the second is the newer GUID Partition Table (GPT). The bootable
Windows partition must exist in both of these tables. The MBR table is stored at the beginning of the drive, followed by the GPT header and array of partition entries. There is also a backup copy of this GPT header and array at the end of the drive.
The MBR does not contain the correct code needed to boot Windows. The
BIOS boot methods reads at least the first 512 bytes stored on the
boot drive into memory and execute the code contained in this 512
bytes. These bytes are referred to as the MBR which also contains the
MBR table. This code reads the MBR table and determines which
partition to boot Window from. If this code is missing or incorrect,
Windows will not boot.
Finally, the Windows Boot Configuration Data (BCD) is missing or
contains the wrong data. If a change is made to your computer or if
the Windows partition is moved regardless if within the same or to
different computer, the BCD may need to be corrected or simply
recreated. As far as I know, this can only be done (without using a
third party tool) by booting from proper Windows installation media.
In your case this would be a DVD containing the Windows installation
software.

The output from the fdisk command shows the MBR table contains some incorrect values. This output should have appeared as shown below.

users-iMac:~ user$ sudo fdisk /dev/disk0
Disk: /dev/disk0    geometry: 121601/255/63 [1953525168 sectors]

 2: AF 1023 254  63 - 1023 254  63 [    409640 - 1168862256] HFS+
 3: AB 1023 254  63 - 1023 254  63 [1169271896 -    1269536] Darwin Boot

Basically, your forth partition (where Windows resides) has the wrong id (partition type) and is not flaged as active (bootable).

The MBR table can be corrected by using the fdisk command. This command is interactive. An example the the necessary command line entries is shown below.

users-iMac:~ user$ sudo fdisk -e /dev/disk0
Password:
fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory

users-iMac:~ user$

NOTE: For you can just hit a return instead of entering values for the entries shown below. This will instruct fdisk to use the default values. This is what I did in the above example.

Do you wish to edit in CHS mode? [n]
Partition offset [0 - 1953525168]: [1170541432]
Partition size [1 - 782721552]: [782721552]

If you have System Integrity Protect (SIP) enabled, you may have to temporarily disable SIP in order to execute the fdisk command.

If after correcting the MBR table your Mac will not boot Windows, we can try to determine if the other causes listed above may also be at fault.


Curl from Pastebin messes with carriage returns Whenever I use curl to get a file like .profile from Pastebin, the .profile file isn't read properly. I did some checking, and it seems to be down to the carriage returns.

How do I solve this problem? Can I correct the carriage returns in transit?

For reasons that pass understanding pastebin.com raw mode uses Windows line endings - carriage return followed by linefeed - rather than plain linefeed that is used by all right thinking operating systems.

So you need to remove the carriage returns. The easiest way to do this is using tr.

curl https://pastebin.com/raw/qg0r3wt | tr -d '\r' > .profile

That will save the contents of the pastebin qg0r3wt into the file .profile with carriage returns removed.


How do I get a folder to stop forgetting its sorting options? I have a folder (my home folder) which I like to have in icon view and kept arranged by name.

However, every day or so it seems to forget the sorting - although the view options panel seems to think that the option is still valid.   I have to change it to arrange by another criterion and then re-select arrange by name.

This is rather irritating, to say the least.  Does anyone know how to fix the Finder's forgetfulness

"Arrange by Name" is a one-time command to arrange the icons. When an item in the folder gets deleted, or new ones added, they don't adhere to this rule, until you force another "Arrange by Name". It looks like this is the behavior you are seeing.

The solution is to choose "Sort by Name", which applies an ongoing rule.


Is Safari on iPad and iPhone identical? I have an iPad for testing websites I develop but am wondering, does this completely cover me for the same version iOS on a mobile?

And I don't mean roughly, would it be exactly the same code base for Safari regardless of the device (so long as the operating systems were the same)?

The binary might be the same, but the code contains conditionals so that some parts works differently on the iPad compared to the iPhone. Just check out the user interface - they are definitely not identical.

Besides, there's obvious differences in for example screen size, resolution, CPU speed and RAM.

If you haven't got an iPhone to test with you could download Xcode from Apple and use the iPhone simulator to test your web sites with.


Bulk remove provisioning profiles on iPhone Over time I've accumulated many (valid) provisioning profiles on my device, and now have  over 400 in Settings. The only way I know of removing them is going into each one individually.

Is there an easy way to remove many of them at a time?

Turns out that using the Organizer in Xcode allows you to do this.


Create Wi-Fi access point in macOS without Internet connection I want to use Keynote.app on my iPhone to operate a Keynote presentation on my MacBook Pro. In order to do that, both iPhone and Mac needs to be on the same Wi-Fi network. But sometimes, there is no Wi-Fi available or it is really unreliable.

I used to solve this by creating Wi-Fi access point on my MacBook. But with macOS High Sierra, it looks, that you cannot create proper Wi-Fi access point without tethering Internet connection. Because, in case I am not connected to ethernet, after creating the Wi-Fi access point in MacBook, I can see it on my iPhone in the list of available Wi-Fi networks, but it says, it has no Internet connection. So even if I try to connect to it, it shows this little tick icon next to the name of the wi-fi, but there is no Wi-Fi icon in the iPhone status bar. And it acts like it is not connected to the Wi-Fi as I am not able to manipulate the presentation through the Keynote app.

The same counts if I want to control some game with my iPhone (like Real Racing 2, which needs both iPhone and Mac to be on the same Wi-Fi network).

Is there any chance to creating a Wi-Fi access point on MacBook that is not otherwise connected to the Internet? I have tried searching for a solution on StackExchange and on the Web but to no avail.

This sounds like your iPhone deciding not to use the Wifi network it is connected to - perhaps it is instead directing all traffic to the Cellular data connection, since that does have internet access.

Perhaps try Disabling Cellular Data in addition to what you've already done above, so the iPhone has only one available network to send data to.


How to copy an image from screenshot's markup? When I capture a screenshot with Cmd + Shift + 5, I can edit the image within Apple's Markup editor, like so:

Is there a way to copy that image (which may have been edited) without saving it?

I just need to be able to copy it within that interface, so I can delete it clicking in the trash icon in the upper-right corner.

It appears you can just hit cmdc while in the Markup editor and it copies it to your clipboard!
So summary of steps:

cmdshift5
Move the little capture box around, resize as desired, then hit return
Click the little preview image in the bottom right of your screen
Mark up the image as desired
Click somewhere, in a non-marked up area, to unselect any markups currently selected
cmdc
Hit the trash can icon to make it go away, without saving
cmdv it somewhere to paste it.

I used these steps just now to paste this image:

I am on Mojave/10.14. I came here looking for the same thing. I happened to find this comment on Reddit that suggested this.


Considerations when connecting an 11" 2011 MBA and 13" 2012 MBP to a 2560x1440 Dual-link DVI monitor This blog post by Jeff Atwood about the amazingly cheap and sketchy, but awesome 27" 2560x1440 Dual-link DVI Korean monitors got me wanting one.

I have a 11" 2011 MacBook Air and a 13" 2012 MacBook Pro. These monitors are typically no-frills no-thrills Dual-link DVI only, so I would be purchasing an Apple-branded Dual-Link mini-DisplayPort to dual-link DVI adapter and connecting it via the Thunderbolt port on each laptop. The specs for both of these say that it should be able to drive a display with this many pixels without issue.

Is there anything else that I should be taking into consideration other than poor 3D performance at that high of a resolution, or should this setup be fine given the proper adapter?

It should be fine. Apple themselves offer to sell you a 27" display along with the laptop so it clearly is capable of driving that many pixels.

I myself use a 15" 2012 MBP Retina with one of those mini DisplayPort to Dual-Link DVI adapters (hooked up to a Hazro 27" monitor, so cheap no-frills much like you're considering) and its been pretty good. This is in addition to also driving a cinema display of the same size, so I have two external monitors.

I read a lot of reviews around the Internet before buying it, and there's a few horror stories (most of them say make sure you get one with firmware 1.03, but there's no way to tell what firmware you have, till you plug it in! - fortunately mine was 1.03 from the off).

The only issue I have with mine is occasionally (maybe once or twice a day) the Hazro monitor goes blank for a second, then comes back on. I have no idea whats causing this, the MBP doesn't even notice (doesn't try to rearrange windows or anything) and its infrequent enough that I just live with it. It may be a slight incompatibility between some of the equipment.

I do suffer from some occasional oddities if I unplug the external monitors while the MBP is asleep, then wake it up (the internal screen won't come on, I think its the graphics card drivers crashing at the unexpected situation) but I don't believe thats related to the Dual-Link DVI.


How to view page source in Safari browser on an iPhone? I thought there'd be an easy way to do this, but I may have been wrong.
How can I view the source for a web page using Safari browser on an iPhone?

Apple’s native solution is Safari Web Inspector. Currently all developer tools for iOS do still run on macOS so get out your mac and dive in if you want a first party solution.
Here’s a 5 minute tech talk, but the developer site has hours and pages of content depending on what you are going to do with this.

How to reset a salvaged Mac Pro which has previously been managed? My buddy hauls junk and the Art Institute of Philadelphia closed down and had him remove a bunch of old iMac/Mac Pro’s from the college.

I now have my hands on a Mac Pro 2010 tower and Cinema Display or whatever.

This computer has deep freeze, and every time I turn it on it auto logs in to the “student” account which has a password. The other accounts (admin/cs-admin) are locked up too.

I’ve tried recovery mode, for some reason it won’t boot in recovery. In single user the commands to add or delete user accounts won’t work either, I get errors every time.

Worth pointing out is the GPU (Radeon 5770) wont work on Mojave so I need to run High Sierra.
I just installed high Sierra on an external hdd as well.

Is there any way to bypass the existing hard drive in order to just wipe the whole thing clean and have a out of the box copy of Mac OS X?

Been trying to figure this out all night so any help is appreciated

That machine is too old to boot to internet recovery. You will need to bring another OS - perhaps installed on an external hard drive and hold the option key when you boot. A DVD works as well, you will likely be able to copy files off but will need some skills to bypass deep freeze, that’s designed to keep out highly motivated teens with hours of free time.

The easy path is to erase the drive and install the OS you please.

https://support.apple.com/en-us/HT201255

The help above shows the various startup keys and links to other articles on reinstalling.

Eventually, your path will land at the bottom of this article covering other ways to reinstall if you can’t get past deep freeze.

https://support.apple.com/en-us/HT204904

Since you have an external, just use disk utility to wipe and then clone it or rerun the installer once you have backed up any files you want.


Xcode 4.1 does not show any recent projects I would like to ask you what is wrong with my Xcode 4.1. Every time I launch it, it show me that there are "No recents" nevertheless the fact that I have created lots of projects.

P.S.:

  defaults write com.apple.Xcode NSRecentDocumentsLimit X

does not work

Thank you in advance.

Recent items menus can be tied to the "Number of recent items" preferences for the Finder in System Preferences, but this is particularly true for Apple's software now. Setting the OS preference for "Documents" to anything other than "None" will activate that feature in Xcode. I wouldn't have done it that way either.

You might have to Quit and Discard Windows Command-Option-Q, change the number in the general pane and relaunch Xcode. It's a bit convoluted to get the change active with all the recent "save your workspace" changes in Lion.


Any Pdfinfo -terminal tool in OS X? I am trying to find any default tool in OS X by which you can see in Terminal the encodinf of a pdf file.

You can do this visually by clicking info on the file.

For instance, such files which have Mac OS X 10.10.2 Quartz PDFContext I want to get out of my System.
So my task is actually find those files and then find original ones and convert them correctly to right encoding via LaTeX.

Outputs of the commands in answers

Command mdls in fd0's answer

mdls -name kMDItemEncodingApplications -raw OxfordDictionary.pdf

gives

(
    "3-Heights(TM) PDF Producer 2.0.5.0 (http://www.pdf-tools.com); modified using iTextSharp 5.0.0 (c) 1T3XT BVBA"

Installation of brew install Caskroom/cask/pdfinfo wants sudo so I had to reject it in my current settings. The mdls seems to work sufficiently.

How can you see the encoding of pdf-file in OS X Terminal?

Just get Xpdf 3.04 from foolabs.

If your current system is Yosemite get the precompiled binaries: xpdfbin-mac-3.04. The 64-bit installer available there doesn't work. Uncompress/Untar the tar.gz and install this binary package manually:

Copy the 64-bit executables (xpdf, pdftotext, etc.) to to /usr/local/bin.
Copy the man pages (*.1 and *.5) to /usr/local/man/man1 and
/usr/local/man/man5.
Copy the sample-xpdfrc file to /usr/local/etc/xpdfrc.  You'll
probably want to edit its contents (as distributed, everything is
commented out) -- see xpdfrc(5) for details.

Check your $PATH if the executables don't work.

If your current system is Mavericks, Mountain Lion or Lion the above-mentioned 64-bit installer should work.

Now continue like Matteo mentioned:

To extract it with pdfinfo:

pdfinfo file.pdf | grep ^Producer


How to choose keys in keychain access? I would like keychain access to store all my keys and passwords for my ssh accesses.

However, if I store too many keys, I get "Too Many Authentication Failures" since SSH will try to send all keys and passwords.

Is there a way to choose which key or password to send?

Put your per-server SSH-configuration into ~/.ssh/config like this:

Host useKeyOnly.net
user sshuser
Identityfile ~/.ssh/mykey1
IdentitiesOnly yes

Host usePasswordOnly.org
PubkeyAuthentication no
Port 53221

16, 32, 64 GB iPhone / iPod touch: are there any negative effects of size? I am debating between purchasing the 32 vs. 64 GB iPod touch.

I would lean toward a smaller hard drive if there is an effect of size on speed or battery life. Aside from cost, are there any reasons not to get the larger memory? Specifically, is there any effect of hard drive size on speed or battery life?

It shouldn't have any impact on performance or battery life.

I believe the same number of flash memory chips are used in the 32 GB and 64 GB models, just in different capacities, so the power drain would be almost identical. Either way, flash memory  takes up very little power compared to things like the screen and wireless radios, so any impact would almost certainly be unnoticeable.

As for performance, I haven't seen any metrics on it, but iOS performance isn't really affected by device capacity. The possible exception here is when you have very little free space, but that's just a guess.

Bottom line, I would suggest not worrying about it - just buy the capacity based on your budget and needs.


No Users on my MacBook Pro My laptop became unresponsive yesterday and so I forced it to reboot. When it turned on again my user account didn't pop up as it usually does, neither did guest. There was only the option for "Other..." and it prompted me to enter 'User' and 'password' so I entered my name as it would usually appear and my admin password but it wouldn't accept it!

I followed other steps online suggesting I use Terminal to reset my password (although i'm confident I am typing the correct password), but then it says to select a user account and won't give me any options!

I haven't backed up my photos and I'm worried I will lose them all!

You can backup your photos by entering in Single User Mode and then :

Steps

type mount -uw /

Then type du -h /Users/home directory/Picturesby this you can find out the space taken by your photos.(If you don't know the name of your home directory type ls -la /Users

Then plug in another pen drive larger than the size of the photos

Then type mkdir /usb

Then type mount -t [filesystem of pen drive] /dev/diskX /usb (X will be your disk identifier

then Press enter and type rsync -p -o -P /Users/homedirectoryname/Pictures /usb

After the copying process is over type shutdown -h now

This will copy  your entire photos library which you can open on another mac.


Why does Python keep popping up and occupying my CPU? I occasionally get Python popping up and occupies all my CPU

I have no clue why this is happening, because I almost never run Python on my laptop.

Here is an update on December 9, 2020
I think the issue comes from a VS code extension called "Python", and you can check out the corresponding issue in its Github page.

Python with a capital P is the launcher app, found at /System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app
This is used when a python script uses MacOS GUI components, such as creating a window, dialog or file panel.
It's likely that some process is calling a python script to do something. What that is and why it's using so much CPU is unclear without more analysis. In Activity Monitor, you can see what files the process is using, which would be a place to start.


How do I install virgin Leopard on external drive with iMac running Lion? I have a new iMac, quad core with Lion running. I want to install Leopard on an external drive to run some hardware that will not work work Lion.

I have formatted the external drive as Mac OS journalled and used GUID but when trying to install Leopard the Installer will not let me choose different installation drive

Short answer is: You can't. Your iMac will only boot up with OS X version that it originally came with, or newer. Since you mentioned you have a new iMac, guess is it's new enough that it won't boot up using a Leopard install, even if it's on an external drive.


My hard drive is broken on my Mac, I have a new one, but how can I install OS X? I couldn't figure out how to properly explain the issue in my title.

Here is the deal:
My HDD is broken in my MacBook, every time I boot it up it's freezing. I bought a totally new SSD, but I didn't think before I bought it, so now I am stuck in a bad situation. I cannot download a new OS X, because they are downloaded from the App Store and I can't use my MacBook. I can't use disk utility to format the SSD either, because funnily enough, I also need my MacBook to work to do that.

So what options do I have here? The HDD is not operational at all, I do have a Windows desktop if I can do something here though.

Maybe I should also mention my insane stupidity of not having my installation disk either. I have an external harddrive though, so maybe if I could get the OS X iso and get my external Hard drive to install OS on the new SSD. But right now, I'm deep in the water.

You can purchase Snow Leopard from Apple for $19.00US and install it from a optical disk reader. Once Snow Leopard is installed, (it needs to be v.10.6.8,) upgrade to Yosemite through the App Store. Make sure your MacBook is not too new to run Snow Leopard, though.


Terminator (Ubuntu) like app for OS X Yosemite I'm using Ubuntu on a daily basis, and recently (6 months ago) I bought a Mac, so the first thing I did was installing VMWare and Ubuntu on my MBP.

I'm a developer and a huge fan of Terminator. With Terminator, you can open multiple file in one window, code separatly on them, and many other great things.

I thought that if it runs on Ubuntu it could possibly run on Mac OSX but it seems that it doesn't work.

Is there a Terminator-like terminal app for OS X Yosemite?

Use iTerm2. Can do most things that Terminator does.


Trying to upgrade, OS X installer can't find hard drive The hard drive in my mom's MacBook (2,1) was dying so I got her an Adata SSD and replaced the original hard drive with it. I booted it up with her original Mac OS 10.4 install CD and used disk utility to format the SSD to have a single HSF+ partition and successfully installed Mac OS 10.4 on her laptop.

Next I tired to upgrade the OS using my Mac OS 10.5 install CD, but the installer reports that it couldn't detect Mac OS 10.4 on the computer. This is not true, when started, the laptop can boot right into Tiger.

When I turned on disk utility, in the OS 10.5 installer, no hard drive could be found. When I ran the command "diskutil list" in the terminal, in the OS 10.5 installer, no hard drive was found. However when I ran System Profiler, in the installer, I could find that under

Hardware > Serial-ATA

there was an "ADATA SP900" under "Intel ICH7-M AHCI" so the installer knows there is a drive there, even if it isn't detecting it.

How can I get the installer to recognize that I have Mac OS installed on my mom's laptop?

I got it to work by booting my mom's computer in target disk mode and attaching my Mac with a firewire cable and rebooting my computer with the installer cd.

The installer, running on my computer, was able to recognize her disk and I was able to install the update.

Unfortunately this solution required a second mac to work, and both macs need to have a firewire port (which are quickly disappearing from Apple's products).


Xquartz on Mavericks 10.9 fails There is an issue with running xquartz on my system.  I installed it by using the link from the Apple website. However when I run xquartz from terminal I get:

:~$ xquartz
/Applications/Utilities/XQuartz.app/Contents/MacOS/X11: line 10: /usr/local/bin/bash: No such file or directory
/Applications/Utilities/XQuartz.app/Contents/MacOS/X11: line 10: exec: /usr/local/bin/bash: cannot execute: No such file or directory

This is preventing me from launching xquartz/x11 applications that I downloaded through macports.  How can I resolve this so that xquartz runs properly?

/Applications/Utilities/XQuartz.app/Contents/MacOS/X11 is just a shell script that executes whatever is defined as $SHELL in your environment:

case $(basename "${SHELL}") in
    bash)          exec -l "${SHELL}" --login -c 'exec "${@}"' - "${@}" ;;

(etc).

In your case, it look as though $SHELL is set to /usr/local/bin/bash, which doesn't exist. What's interesting, though, is that since you have a prompt at which you have typed xquartz, you clearly are running a shell of some description. However, it doesn't correspond to the value of $SHELL.

Two suggestions for how this might happen:

$SHELL will normally reflect the login shell for your user. You can set that in System Preferences -> Users & Groups -> right click on your username and choose "Advanced Options". If you set this to an invalid value, you won't normally be able to open a terminal... unless you go into the Terminal.app preferences and set the "Shells open with:" option to something which does exist. You'll then get a working terminal with a non-existent $SHELL.
Alternatively, it might be something in your shell startup scripts (.bashrc, .profile, etc) which export a misleading value of $SHELL to the environment. If you have customized any of these, take a look and make sure you're not setting things up incorrectly.


iPad app to access Mac files? Is there an iPad app that that can open Mac files over WiFi on the iPad?

I'm looking for something like Dropbox, I really like the feature it has where you can open the files in Dropbox in other apps on the iPad. I need something like that, just for regular files that are not on Dropbox. Something like Air Video but sends the files to the appropriate application instead of just playing videos in the app.

To be clear, I'm not looking for Splashtop or a similar VNC app. I want to use native iPad apps to open these files.

I'm open to a jailbreak solution, too.

Answering this

  Is there an iPad app that that can open Mac files over WiFi on the
  iPad?

I bought a app called Files Connect on my iPad, I use it to access files over the Network to access shared folders on my Mac using my iPad and iPhone. It is universal app for iPhone/iPad.

It works also with Windows PCs, Dropbox and other services.

You can also use it to access your iPad files using the Mac/Pc (opposite way)

I bought for $5, This is looking too much as a ad (I'm not related to this company), so read description for details.

Bootcamp Windows 7 installation, USB is not recognized only on bootloader I'll abstract my question.

I'm using MacPro4,1 Early 2009. And I'm trying to install Windows 7 Professional x64 SP1. (I'm using Yosemite 10.10.4, and Boot Camp Assistant is 5.1.4)
My Mac has 2 HDDs, one is installed Mac (disk0), the other is formatted as FAT (disk1)
I edited info.plist of Boot Camp Assistant to show USB install option, and created bootable USB with Boot Camp Assistant
OS X recognize my USB as Windows Installation Media. (I tested it with Boot Camp Assistant app)
But when I reboot Mac with USB inserted, bootloader of OS X does not recognize my USB as installation media (When I used alt/option to load bootloader)

…and it shows just black screen with blink cursor
I tried rEFInd. it recognized USB and showed windows, but does not work either.
I also tried to create a new installation USB media from Windows, and it didn't work. (with Windows DVD/USB tool, UltraISO, BOOTICE)

Please note that the USB I have, has already been used to install Windows on several PCs without any problem. (Win 7,8,10)

What should I do?

I checked many Q&As from Apple Discussions, here, Macrumors, and so on. Nothing worked.

I attach answer here as you guys suggested.

SOLVED - Bootcamp Windows 7 installation without USB, ODD

OK, I'll explain how I worked it. I followed almost of all of David's method here and here, but there are little differences.

Before we start, please note that I'm using MacPro4,1 which does not support USB installation of boot camp and I detached ODD. Instead, I attached another HDD in Bay 2.

You need rEFInd, VirtualBox, NTFS support for OS X (like Paragon or NTFS-3G), a bootable Windows installation ISO.
Service Pack applied ISO is also ok.
Update Mac firmware as recent one as possible. here
Open Boot Camp Assistant and download driver files into any usb.
(Just 2nd option of 3 of boot camp. if your boot camp assistant does
not have 3 options, it would be 1st option)
install NTFS support for OS X, rEFInd and VirtualBox.
Format a partition with MS-DOS(FAT) which is going to install
Windows.

I recommend you not to use Boot Camp Assistant app to format. Use Disk Utility instead.

In terminal, type diskutil list and remember disk and partition
number of target partition. In this example, I use disk 1 and
partition 1. So, disk1s1
Unmount partition and set permission.

diskutil unmount /dev/disk1s1

sudo chmod 777 /dev/disk1s1

Create VirtualBox image with raw disk access. anywhere except
bootcamp partition

sudo vboxmanage internalcommands createrawvmdk -filename bootcamp.vmdk -rawdisk /dev/disk1 -partitions 1

sudo chown $USER bootcamp*.vmdk

Open VirtualBox and create a VM. Just set disk as what you already
made, and ISO file of windows installation.
Start VM and install as normally, BUT when you get in 'setting
 computer name' phase, shutdown VM forcibly.
Turn off VirtualBox, and delete all files in the boot camp
 partition (including BOOT folder and bootmgr file - If you can not
 find them in Finder, use terminal to delete them or change Finder
 option with defaults write com.apple.Finder AppleShowAllFiles YES)

Of course, Before open finder, mount partition first.
 (If you didn't installed NTFS support, you can't mount or delete file)

diskutil mount /dev/disk1s1

double click windows ISO and copy all of the item into boot camp
 partition
Reboot Mac and in rEFInd bootloader, select 'Windows NTFS volume'
Install windows again, but DO NOT format boot camp partition.
Installation is finished. When you see desktop, install Boot Camp
 Driver which you downloaded at Step 3
After boot camp driver is installed & if you can see 'Windows' on OS X boot loader (which you can enter by pressing alt/option), you don't need rEFInd anymore. You can delete it in OS X.
You will see bootup selection between 'Windows 7' and 'Windows Setup' when booting Windows. If you don't want to see it,
Go to Control Panel - System - Advanced Settings - Advanced tab - Click Setting button which lies on 'Startup and Restore' section - Uncheck first one.


Should I delete my backup on my iPhone? I want to delete my backup because it’s taking up all my storage but I’m scared too because I don’t want my photos deleted nor my saved games and stuff to be messed up in some way. So if I delete my backup with my games and instagram and Snapchat will it still be the same ??  What happens when you delete your backup ??

If you delete your backup nothing will happen to your current photos or apps. If in the future though you try and restore from your backup your data will be lost.

To free space if you have a compatible computer you can backup to iTunes which won't use any iCloud space and will only use space on the computer.

To backup to iTunes:

Update to the latest version of iTunes.

  Open iTunes and connect your device to your computer.

  If a message asks for your device passcode or to Trust This Computer,
  follow the onscreen steps. If you forgot your passcode, get help.

  Select your iPhone, iPad, or iPod when it appears in iTunes. If your
  device doesn't appear in iTunes, learn what to do.

  If you want to save Health and Activity data from your iOS device or
  Apple Watch, you need to encrypt your backup: Select the box called
  Encrypt [device] backup and create a memorable password. If you don't
  need to save your Health and Activity data, you can make a backup that
  isn't encrypted. Just click Back Up Now.

  When the process ends, you can see if the backup finished successfully
  on the Summary screen in iTunes. Just look under Latest Backup to find
  the date and time.

How to make a test user without a credit card? I'd like to create a test user in iTunes Connect, so I can test in-app purchases. However, iTunes forces me to enter credit card information. Considering this is a test user, for a sandbox environment, that is not supposed to be spending any money, it looks pointless. Is there any way around it? (I know that it is possible to create a new account with no payment option, but then it won't be considered as a test user.)

OK, as it turns out the test user can only be used from within the sandbox environment, which makes certain sense. This is described here.


Two login accounts, admin account password unable to login I made the mistake of making two accounts- admin account and standard account after upgrading to Yosemite beta 10.10.1.
(The reason? I read that it would be "preferable" to set this up because of the security flaw which still has not been addressed, but that's another issue).

When I login, I first have to login with my admin account & password.
Then another screen comes up with both the admin account and the standard account and a black rectangular shape at the left-hand side of the bottom the page which tells me to login. A white rectangle outline is on both the standard account image and the password section. I then enter my apple ID password into that white outlined rectangle. This is how I get into my computer.
(I had many many other problems from Yosemite which I have remedied slowly)

BUT the problem is:
I have locked myself out of the admin account somehow.
The admin password I login with, does not work anywhere else. For instance it does not unlock anything that requires to unlock the padlock - such as System Preferences.

I cannot access Disk Utility, cannot unlock or put in my admin password.
I cannot turn FileVault off or the Firewall
I cannot upgrade software that requires admin password.

What can I do to regain admin access? (I cannot do this in System Preferences because I am locked out). Do I have to reset my default keychain?
What do I need to do?

First, setting up separate admin and standard accounts was NOT a mistake. It is, in fact, a Good Idea™.

When you need to authenticate (for example, to unlock a padlock), you need to enter both your admin name and your admin password. If you're in your admin account, the name will be filled in for you. If you're in your standard account, both the name and password fields will be blank, and you need to enter them both. Be sure to enter the admin's name and the admin's password.

Why is my "New Zealand" bookmarks folder not appearing on my iPhone? I am using iCloud to sync bookmarks from my iMac to my iPhone. But one bookmark folder is not appearing on the iPhone.

On my iMac (OS X 10.7.5), in the iCloud pref pane of System Preferences, I have verified that Bookmarks is checked.

On my iPhone (iOS 6.0), in the iCloud section of Settings, Safari is marked as on.

One difference which I believe is insignificant is that OS X shows the account name as @me.com and iOS shows the account name as @mac.com.

The iMac has a bookmarks folder like this:
Bookmarks Bar > travel > New Zealand > (approximately 15 bookmarks)

The iPhone has:
Bookmarks Bar > travel

and:
New Zealand > (empty)

The top-level New Zealand bookmarks folder does not exist on the iMac.

I tried turning off bookmark syncing on the iPhone, choosing to erase all bookmarks, then I turned it on again. When syncing appeared to be done, the New Zealand folder was not where I expected it (in Bookmarks Bar > travel).

Is there anything I can do to fix this? Should my next step be to report a bug to Apple?

I see that an Apple support document recommends no more than 25,000 bookmarks. I just exported my bookmarks to Safari Bookmarks.html, then ran grep HREF Safari\ Bookmarks.html | wc -l and the result was 3882. So that doesn't appear to be the problem. Next I will work through the troubleshooting steps in TS4001.

I followed the troubleshooting steps in TS4001 (linked in the question), and now the errant folder is on my iPhone with what appears to be the correct list of bookmarks.


Fix Exercise Type in Activity App I did 60m of yoga yesterday and didn’t realize until the end that I had accidentally specified Indoor Cycle as the activity type.  Looking for a place to edit this in the Activity app on my phone and can’t seem to locate this option.  Any suggestions?

Go to Today tab in the Activity tab and swipe to get to yesterday. You should see the activity and its duration in a big box. Tap it, and scroll to find Show all Data. You can delete the particular entry there.

Adding is similar, go to some day you did yoga on, Tap on the said big box and find red + at the top right.


In Reeder for iPhone, how to add defaul recipients for sharing via mail? In the app Reeder for iPhone, when I tap on: "Settings" > "Sharing Services" > "Mail", there appears to be a "Default Recipients" section, with four rows: "Link", "Article", "Text Selection", and "Image". Tapping on any of these rows doesn't seem to trigger anything.

Does Reeder allow one to set up default recipients for mail? How can I do that?

(This is on iOS 6. Reeder's version is 3.0.4.)

It works. Don't tap on the actual word "Link" or "Article" etc... You need to tap the centre of the white space after the word. The keyboard will show up and you can type the default email address :)


iMac Early 2009 restarting after RAM upgrade My iMac is from early 2009 and currently is running Mavericks OS X and has 2 GB of RAM installed. I then purchased 2 x 4 GB strips of RAM that were manufactured by PNY. Specifically, DDR3 RAM which is compatible with 1333 MHz and 1066 MHz.

Once I inserted the RAM into my system after removing the previous RAM, it failed after working for only 5 minutes. However, shortly after, the system rebooted and continued to do this until I shut down the computer on the 4th boot. I then reseated the RAM and ran the system again only to receive the same results. Now that I have replaced the old RAM, the system is working fine.

Does anyone know why this might be happening? Note: this RAM is brand new.

Remove one of the 4 GB strips of RAM so that you are only using half of the total 8 GB that you say you purchased. Does the system run stable? If not, replace that strip of RAM with the one you removed. If the system is still not stable, remove that strip from the slot and insert it into the other slot. If this still does not solve the problem, you may want to try a different brand of RAM.


Return User To Admin Users and Undo Parental Controls For a while, I had only one user, say, User1, on my Mac's High Sierra. Then there arose a need to have some parental controls. To do that I created a new user, say, User2 and made it an admin while User1 was the controlled one.

At present, the need to control is no longer there and all of the information that I need to use is still under User1. My questions are the following.

How can I add User1 to sudo'ers?
Is there a way to get rid of User2 account and restore User1 to its original sole ownership?
How can I make sure all of the deleted user's info and storage is scrapped and freed?

Any help or advice is appreciated.

As User 2

Open Users & Groups
Unlock it with Password
Disable (uncheck) parental controls for user 1
Enable User 1 as Admin

Log out from User 2, log in as User 1

Open Users & Groups
Delete user 2 (you will be offered to save or not the user data)


Macbook Pro 2018 battery not charging dodocool 7-in-1 hub suspected I am having a version of the battery not charging issue on my Macbook Pro 2018 (13-inch, Four Thunderbolt 3 Ports). The symptoms are somewhat different from related issues, such as in this post. I am experiencing the following symptoms:

While power adapter is plugged in, the battery drains, and my system battery indicates "Battery not charging..." even when there are no apps using significant CPU cycles.
The system continues to list the power adapter as the battery source even after I have unplugged it.
I no longer hear the power chime when connecting to a power source.
Battery condition is normal.

I have already tried:

Resetting NVRAM and SMC as suggested here, multiple times.
Attempting to power with different adapters and combinations of third-party USB-C hub accessories.
Booting in safe mode

Bottom line, nothing works. Is there something obvious that I haven't tried?

Update
Apparently some of my USB-C/Thunderbolt 3 ports have ceased to function as well. This is starting to look more and more like a hardware issue related to the USB-C/Thunderbolt controller.

Even further update
A trip to my local Apple authorized repair shop (after my battery had completely drained) revealed that:

a. the battery was able to be charged after some period of "rest"
b. Apple Hardware Diagnostics indicated nothing technically wrong with the machine

Classic bizarro intermittent problem. The only other common thread I've discovered is this: every time this behavior has occurred, I have been using an accessor hub called "dodocool Aluminum Alloy 7-in-1 Multiport Hub with dual USB-C Connectors, model: DC53. I'm starting to suspect that this accessory is at least a necessary cause of the behavior.

It looks like

I will update if the problem persists in the absence of this hub.

I don't fully agree with the steps outlined in the article you reference for resetting the SMC on a MacBook with the T2 security chip installed. Instead, try the following.

Resetting the SMC on a MacBook Pro with T2 chip installed

Fully shut down your MBP.
Press and hold the power button for at least 10 seconds
Let go of the power button and wait 5 seconds
Power up your MBP again

Once you've reset the SMC see if you can charge your MBP. If it's still misbehaving, reset the SMC again but with the following steps instead:

Fully shut down your MBP.
Press and hold the right shift key and the left option and control keys for 7 seconds before then also pressing and holding the power button (or Touch ID button) down for another 7 seconds (i.e. the keys will end up being held down for 14 seconds, the power button for 7 seconds)
Let go of all three keys and the power button
Wait 5 seconds
Power up your MBP again

Now test your MBP again. If you still can't get it charging then it's time to test your hardware with Apple Diagnostics.

Running Apple Diagnostics

Your model MBP uses Apple Diagnostics to test its hardware. You can do this as follows:

Fully shut down your MBP
Restart your MBP
Immediately press the D key and keep it down until you see the Diagnostics screen appear
Wait for Diagnostics to finish (this typically only takes a few minutes)
Once complete, one of two things will appear on the screen:

a No issues found message
a brief description of any errors found plus further instructions

If the diagnostics test does find errors, take a note of what they are

Note: If pressing and holding the D key at Step 3 doesn't work, start again at Step 1 and, at Step 3 press and hold both the OptionD keys instead. This will try and run diagnostics from the internet instead, so you will need to allow more time for it to complete.

If after doing all of the above you still have no joy, then it's time to contact Apple directly.


CD digital audio ripping tool for OS X that has accurate extraction, error detection, and verbose reporting? I'm almost ready to say I have found a good OS X replacement for every piece of software I use on Windows (excluding some Windows development tools), but there's still this gap to fill:

For CD digital audio ripping / extraction, I use a tool on Windows called EAC - Exact Audio Copy.  I like EAC because:

it supports a very reliable extraction mode by default,
it takes advantage of drive features like C2 error correction
(and will tell you if your CD-ROM drive doesn't have it)
it validates tracks were ripped accurately by consulting an online database, and
it reports verbose details about potential issues, when they arise, and I can then listen to the track to see if the issues are perceptible or not.

In a nutshell, I can be confident whether a track was reliably ripped or not when using EAC.

I don't get this sense of confidence from iTunes.  iTunes has an option under Import Settings to Use error correction when reading Audio CDs, but that seems to be the extent of reliability-oriented settings in iTunes. Currently, I'll use iTunes if the disc I'm ripping appears pristine and without scratches – otherwise I turn to EAC.

Is there an application for OS X that, like EAC above, focuses on reliable CD digital audio extraction and provides detailed information?  Thank you.

XLD

It started out as decoder/encoder/transcoder tool but it's branched out in to ripping in recent years (version 20080812 and above have ripping features) and it supports most of your criteria:

Uses the AccurateRip technology, comparing MD5 sums against known-good library of rips to ensure the rip was done correctly.
Uses cdparanoia 10.2 as the ripping and error correction library. Can be used on drives that don't have Accurate Stream and utilize C2 error pointers.

(Source for above)

I can't comment on the "verbose details when errors arise" request because I've never encountered an error ripping with it.

It's free. It will multi-thread to speed up encoding of albums. And it's pretty fast. It's been my encoder/transcoder of choice for years now.

MacBook performance while on battery vs plugged in Should I expect my MacBook Air to run slower while on battery vs while plugged in?

In other words, will it slow down the CPU/graphics/etc while on battery to conserve power?

Yes, sort of. Intel uses a technology called SpeedStep. This technology allows the CPU (and in your case, shared GPU) to adjust its clock speed on the fly, in order to balance performance with power consumption.

When your MacBook Air (MBA) is plugged in (on AC), it is fed the energy it needs, and thus the CPU doesn't have to concern itself with conservation. Conversely, when your MBA is running on battery power, conservation is quite important. In this case, the system will balance performance needs and power consumption in an effort to elongate battery life.

Naturally, your MBA won't be "slower," but the CPU cycles will be allocated in a much more sparingly.

A classic case of software and hardware working together to enhance the user experience (and just another way for Apple to maximize up time).

While I have not personally tried this software, CoolBook claims to have the ability to disable SpeedStep (among other features). Though on their site, they do list that a lack of support for "i3/i5/i7 CPUs", which is unfortunately what most modern Macs are using.


Missing emails on my my laptop vs ipad why am i receiving more emails (gmail) on my ipad than on my laptop. I seem to be getting more email posted to my Ipad than to my laptop.  This morning I received 7 more emails on my Ipad than on my laptop.  Granted they were websites that have something to sell but I have asked for these. Why are they not showing up on my laptop.
Thanks

It's the new gmail interface. Right above the list of emails are three tabs:
Primary   Social    Promotion
You are in Primary, try clicking Promotion and you will see the missing emails.


How do I check where the file in .Trash was removed from? I've some files appearing in Trash folder. How do I check from where they were removed?

I've Tried 'Get Info', but it doesn't tell me from where it was removed. The only option I've is 'Put Back', but again, to where?

How do I check this on OS X 10.9?

Based on the previous information, the information about original location is stored within DS_Store file. In older version of OS X it was just a plain text and now binary format and it's undocumented by Apple, however there is a tool created by Wim L which can reads it.

Written in perl Mac::Finder::DSStore project provides routines for reading and writing the .DS_Store files generated by the OS X.

Using examples/dsstore_dump.pl would attempt to dump a store file's records in a more human-readable format.

Example usage:

$ perl dsstore_dump.pl ~/.Trash/.DS_Store

    &makeEntries("foo.png",
        ptbL => "Users/username/Desktop/",
        ptbN => "foo.png"
    ),

See: dsstore repo at hhhh.org and older repo at GitHub


Any better way to purge the inactive memory? Running purge command in the terminal to free the inactive memory isn't really what I think about Apple.

Lion isn't doing a great at all when it comes to free the inactive memory.
Free memory is reaching 16 MB and applications and the OS are becoming unresponsive, yet OS X isn't reclaiming the inactive memory.

After each session, I put the laptop to sleep. You can say that I shutdown my OS once a month.  Unixes after all aren't created to be rebooted.

OS X Snow Leopard was pretty sleek, I don't know but it looks it is a Lion thing (maybe due iOS brought to Lion features).

Any better way to reclaim the inactive memory on Lion?
[EDIT]
I got 4 GB of RAM

Yes, you can, one command only (run in Terminal):

purge

And recheck inactive RAM


syncing favorites from computer to iphone I can't sync my favorites from my pc to my iphone 3G through icloud, they say it will will do it through the air, yeah not happening? Please HelpI've tried everything even deleting and it goes back to the origional computer that I set it up on??

Do you have the iCloud control panel for Windows installed ? It looks like :

To use this control panel with iCloud bookmark syncing you must have at least :

Windows Vista Service Pack 2 or Windows 7
"Safari 5.1.1 or Internet Explorer 8 or later is required for accessing bookmarks"

You can find an illustrated set-up guide here.


How many external monitors does the iMac 27" with 5k display support? Specs indicate just 1. Has anyone connected more than 1 monitor successfully? How many can you connect in total?

The Late 2015 iMac 5K with AMD 395X can support two external 4K (UHD) displays (at the full 3840x2160 res) with the builtin iMac display set to 5120x2880 FYI. This is the configuration that I am currently running (with 10.11.2), using two LG 27MU67 displays attached via DisplayPort-to-miniDP cables on each of the iMac's thunderbolt ports.


Intel Mac mini - maximum RAM Upgrade I have a Mac mini with a Core 2 Duo processor (2.4 Ghz). I plan to upgrade the RAM in my Mac mini. Currently, it has 2GB right now, 1GB per slot (2 slots total). I would like to buy a new 4GB for a single slot.

This means I would have 4GB in one slot and 1GB in the other slot. I have heard that 32-bit OSes don't support more than 4GB of RAM. Is it the same case here?

To find out the architecture of my Mac OS, I used this command:

uname -p

It shows i386, it means Mac OS X is running 32-bit operating system. Will there be any problem while upgrading RAM?

Summarizing My Question

What is the maximum RAM supported in this Mac mini? (Mac mini 4,1 - new version of Mac mini) Will OS architecture be a constraint while upgrading RAM? Is this constraint applicable to my current case? How?

For starters, OS X doesn't have the silly 64/32-bit dichotomy that Windows and Linux do. For most purposes, you can consider recent versions of OS X to be both 32- and 64-bit at the same time. The limiting factor in almost all cases of upgrading Mac RAM is the hardware chipset.

For your Mac mini 4,1: my copy of Mactracker says that the maximum RAM is 8GB. Your five-gig setup should work fine.


Install second operating system on internal (as VM with Parallels) or external drive? I am using an old MacBook and I want to keep my operating system. For coding with Xcode I would need a newer version of OS X.

My question is, if the performance is better when I:

Install the new operating system on internal HDD via Parallels.
Install it on an extern HDD and boot the laptop from there.

I just want to code in Xcode so the only thing that matters to me is performance.

A native OS is always faster than one running in a virtual machine.

That would seem to be obvious, so edit your Question if I am misunderstanding you, or if you had other issues or complications in mind. If your external drive or connection is slow, then booting to external might be about the same as the VM on internal drive, or even worse if using a USB 2 drive/connection. On a Thunderbolt drive, you will be running faster than than will the VM on internal.

On the other hand, I have successfully done Xcode programming in a VM in Parallels. The performance is surprisingly good.

There are always niggly glitches and bugs in Parallels, and always changing version to version as some get fixed while new ones appear. But I've encountered no showstoppers, just annoyances. The most serious bug suffered by me and reported by others is that the mouse suddenly and inexplicably becomes useless within the VM. The workaround is to suspend and restore the VM. Takes about 10-20 seconds, and solves the problem reliably, but is quite annoying.

Currently, there are still issues with trying to run the VM in Retina mode. While it generally works well enough, it really slows down performance noticeably. And a few apps malfunction, misinterpreting the resolution, causing the content of their windows to be dramatically zoomed in, rendering the app unusable. In addition to some web browsers, this happens in the Xcode Simulator. Workaround is to shutoff Retina mode in your VM’s settings.

Another benefit of a VM is keeping Apple's confusing array of settings and security certificates in Keychain all stored nicely in the VM and kept separate from your own stuff on your real Mac. If doing a clean install or moving to a fresh Mac, would you know how to move all the pieces needed to keep Xcode and iTunesConnect happy?


Is there a way to use automator/write an apple script to change the font in several powerpoint documents? A recurring issue at work:

A powerpoint file needs to be moved in to illustrator and saved as an .eps file. The files are almost always submitted with the font set to Calibri which Illustrator doesn't like for whatever reason. I select all the type and change it to Univers which usually enters Illustrator quite well. I'm looking for a way to speed up this process. I'd like to be able to put all my .ppt files in a folder, select that folder, have all the documents open, the type selected and changed to univers (Univers LT Std 55), then have the file save and close. Any advice?

Thanks!

Short answer:

Yes, it's possible. You just need to use the Record button in Automator to record your own mouse movements as you change the font in one PowerPoint file. Then save this recording as a Folder Action. Now every time you drop a some files into a folder with this action, it will automatically run at your mouse movements on those files.

I'm including a screenshot of a proof-of-concept Folder Action that I made just now, but in all honesty, this will probably take a lot of tinkering around and may not be a very clean way to do it.

Better answer:

There is a better way to do this but it will only work on the new .pptx format presentations, not on any of the old .ppt files.

Basically, all you have to do is rename your powerpoint as .zip and then unzip it like a folder.

Once you open the folder, navigate to:

ppt > slides > slide#.xml

Where the "#" is slide number you want to edit. In my case, I only have slide1.xml but you will probably have others too.

Once you open the xml it should be pretty straightforward to search the xml text for the word Calibri and replace it with the words Univers LT.

That's it :)

All you have to do now is save the xml, zip the folder again, and rename the zipped file back to .pptx.

This may sound tedious to do, but I'm sure it's possible to write a simple 5-10 line bash script that will do exactly this. Unfortunately, I can't do it tonight so perhaps one of the mods can help out and post a script for me.

If I have some time tomorrow, I'll try to write one for you and test it on my computer. :)

How to delete all photos from the iOS 7 camera roll WITHOUT importing them? I have 4000 photos in the camera roll
I don't want import them into my MacBook's iPhoto or nowhere, so
simple want delete them directly in the iPhone (iOS 7).
selecting them one-by-one (you sure agree) is NOT very user friendly

What is the "Apple way" of doing this (usually) simple thing?

On iOS 7

Open the Photos App and make sure you are in the “Photos” section from the three icons at the bottom of the screen;
Look at the top of the screen and make sure the view is “Moments;”
Now you can tap individual thumbnails one at a time to select them, or you can tap the word “Select” that appears at the top of each grouping to select an entire grouping.

On iOS 6

Go to Settings → General → Usage → Photos & Camera;
Swipe on the “Camera Roll” entry;
A “Delete” button appears.

This solution does not work on iOS 7 (last tested on iOS 7.0.4). It is probably a bug.

Any iOS, but using a computer

If you have iOS 7, you can use Image Capture on your Mac to delete photos from the iPhone without importing them:

Plug the iPhone to your Mac with the iPhone cable;
Quit iPhoto if it launches automatically;
Launch Image Capture;
Select the photos you want to delete;
Click the red icon to delete the photos.


Can't boot Mac OS after applying restoring from InstallESD.dmg So I got a very old Macbook Pro to deal with. It comes with the Mac OS X Lion but nobody seems to know its password because it's a rather dated company asset. I tried to wipe it and reinstall the OS via internet recovery, but it requires the original Apple ID by which this MacBook Pro was purchased which I don't have either. I said so because I tried my own Apple ID and it only told me something like service not available/cannot connect to the server while the internet was perfectly fine.
So I downloaded the installer of Mac OS and extracted the InstallESD.dmg, then used it to restore the OS partition after erasing the whole OS partition. However, it seems the installed OS can't boot, as the start disk is not chosen. But in the start disk list, I can only see either a network server of our company, or the Flash drive I used to restore the dmg file. Is there any way I can resolve the matter please?

Any Apple account that purchased the OS should work, but be sure you enter your password plus pin tacked on the end. The installer wasn’t prepared for MFA or TFA so this is a bit of an edge case.

https://support.apple.com/en-us/HT204915

Search to the bottom for the part

Then type your password followed by the six-digit verification code directly into the password field.

But you don’t really state what you want to do, we don’t know your exact model and if you can just connect this to another Mac in target disk mode and run the installer on a new Mac to install to the old one. Hopefully you can go back to recovery and get the normal install path to work from recovery still.
I’ve had good luck installing the OS I want to an external drive and holding option to boot as well if you don’t want to install direct over target disk mode.


How to disable to login screen shortcut (Cmd+Alt+L) I'm trying to find where this shortcut is being configured under Snow Leopard but I simply can not. Any help would be appreciated!

Not sure what you're trying to do, but Safari uses CMD+Alt+L for the downloads window.

Also, I used to use LockMyScreen (which doesn't work in Snow Leopard anymore), and it's shortcut is showing in my Mac as CMD+Alt+L.

I went to System Preferences > Keyboard > Keyboard Shortcuts, then looked in Application Shortcuts.


MacOS cannot copy "special" files...they are marked with "s" Their permission scheme is srwxr-xr-x.
I can't copy them, as I get the following error message.

cp: cannot create special file '/Volumes/Samsung_T5/Dockers/vms/0/00000002.00001003': Operation not permitted

I tried with sudo, but the files are still not copied, although the message is a bit different. This time, it says "Invalid argument."
And yes, I'm trying to move Docker folder to an external disks as it is filling up my hard disk.

This is a (s)ocket type file. As such, it doesn't have any persistent data associated with it and thus it makes no sense to copy it.
Sockets enable communication between two different processes on the same or on different machines. This communication is done using standard Unix/Linux file descriptors, using read() and write() system calls.


Music starts automatically when headphones are plugged into the iPhone I have an iPhone 5 with the last version of iOS, 10.3.2. When I plug in the headphones into the jack, the music application starts automatically on the screen block, and starting to play music. I have no open application in the background when this happens.
What are the reason and can be solved?

Most normal headphones don't do this but some might or might not start playing. Try pausing your music before you unplug. That should work as a temporary fix.


Safari searches in the title bar require tapping "return" twice This began when I upgraded to El Capitan. Sometimes when I search using the title bar of Safari for a google search, I have to hit the return key twice. A single return will sometimes load search results, but not always.

Deleted com.apple.Safari.plist from my Library folder as part of troubleshooting, but it's still occurring.

I've been having this issue and it's started to drive me nuts. I think I've solved it by altering the search preferences for Safari and disabling most of the 'smart search' options. I've not spent the time going through each to determine which particular option caused the issue. I'm just glad I don't have to keep pressing return twice.


move to trash on ~/.Trash folder Why finder application is showing move to trash on ~/.Trash folder? If you will click on move to trash it will show an indefinite progress indicator that will never ends.

Almost all Mac users won't ever see hidden files and folders in Finder. There's no need for Apple to hide actions on stuff which is already hidden in the first place.

Experienced users like you, who know how to show hidden folders in Finder, should also know that moving the Trash into itself is a weird idea.


Remote access to an iMac Pro So I have a friend, who has an iMac Pro with high specs at his home and I thought about accessing his iMac Pro from my Macbook Pro via some kind of remote desktop service. I would do some rather extensive video editing on that iMac Pro, for which my Macbook Pro is just too slow currently as its a rather old one from 2016. My question now is how i would be able to access that iMac Pro from my Macbook Pro, so I can basically do some kind of screen sharing and use Final Cut Pro installed on that iMac Pro. I tried downloading Remote Desktop from the store, but I can only make it work, when both of our devices are in the same network (we tried it on wifi), but I just wasnt able to make it work when we are not both in the same network, which would be the actual case at hand, because I would need to access his iMac Pro from anywhere. I have seen something with SSH, but isnt that only for servers and such? Either way I just wanted to ask, if someone knows how to best get this setup working.

Use either Screens and Screens Connect or TeamViewer.

https://edovia.com/en/screens-connect/ and https://edovia.com/en/screens-mac/
https://www.teamviewer.com/

Both of these broker connections and work with routers to establish connections across the internet and private networks where routing is not set up for ARD.


How do I connect to a VPN through a HTTP/HTTPS proxy? MacBook Pro (Retina, 15-inch, Mid 2015), OS X El Capitan (10.11.1)

I'm currently on a Macbook Pro mid 2015 with OS X 10.11.1 and I need help bypassing my university's proxy server. I believe they use squid/3.3.8.
Applications such as Battle.Net, Steam, Git, uTorrent and Slack are blocked and I need them. Skype & Appstore seem to work.

I have heard that in order to bypass the proxy I'll have to connect to a VPN, my colleagues managed to connect to a VPN but they're all on Windows.
I've tried several free VPN services and apps such as: OpenVPN, TunnelBlick, TunnelBear, CyberGhost and I couldn't connect to them, it always said that the server is unreachable or that the connection failed. I also tried to connect to a paid VPN using iSstp & L2TP over IPSec but again it didn't work.

I could connect to my paid VPN when I was at home and not on proxy. Also I tried to use software like ProxyCap and Proxifier but they didn't work.

I've managed to connect to the VPN using bootcamp and Windows but I don't want to waste space with Windows. There I used a software made by Hideman VPN which is also available on Mac but it doesn't work on Mac.

I want to know if there's any software that can help me to bypass the proxy. Thank you.

I solved this question by Viscosity a commercial VPN client. It lets me chose the protocol and the proxy server before connecting to the vpn.


Using other glyphs in Arabic on the iPad Arabic Keyboard on iPad uses GeezaPro font and obviously keys are limited compared to available glyphs, but what should I do if I want to use a glyph that doesn't have its own key. Is there any way I can add/use it somehow?  The reason I need to do this is so I can write in Persian/Farsi.

If you search the app store for "persian" you should find a few keyboard apps which will make the characters you are missing and which may be useful for email and some other purposes.


Dual boot on macbook pro 2015 (macOS Sierra and Kali Linux) I have a Macbook Pro (Retina, 15-inch, Mid 2015) with macOS Sierra.

For the installation, I have followed this guide: Installing dual boot Sierra and Kali-Linux but at the end, when I go to part 3 I see only the Mac Hardisk and no other available selection.

Someone have any solution?

I used the guide on Kali's official website for me, which is here: http://docs.kali.org/installation/kali-linux-dual-boot-on-mac-hardware. I to have a MacBook Pro Retina running OS Sierra, I hope that will help your installation.


How do you use your iPod shuffle or nano? I bought my first Apple product a few months ago, an iPod shuffle, a tiny little music gadget that's fun to play with. However its getting a little boring because I don't know what I can do with it or places I can use it. Currently, I'm limited to listening to it during sleeptime as a lullaby machine. What do you do with your iPod shuffle/nano? how do you get the most out of it?

Nanos or shuffles are great for workouts at the gym or while running. You can use them just about anywhere. I personally use a Classic for my stuff, but the nano is great if you have a smaller library or want something very mobile.

As far as what you can do with it (other than playing music), it really depends on which generation you have. You obviously can't really run 'apps' on it, but many generations (of nanos) had some small games, radios, could play video, etc.


App to manage copy and paste? I'm looking for an app to manage copy and paste tasks.

What I need is to have shorcuts to the last copied text.

Let's say I copy these 4 lines in 4 times:

111111
222222
333333
444444

Then I'd like to have 4 shortcuts to paste every one of them. Something like:

cmd + 1 (to paste '111111')
cmd + 2 (to paste '222222')
and so on..

The closed match I found is Clipmenu since it seems that you can use the shortcuts I need (cmd + 1, cmd + 2...) but it doesn't work though

I use FlyCut, you can do Cmd-Shift-V and then cycle through your recently copied texts with arrow keys.


How to downgrade to OS Mavericks 10.9.5 from a new pre-installed Yosemite 10.10.1 iMac late 2013? I need to downgrade to OS Mavericks 10.9.5 from a new pre-installed Yosemite 10.10.1 iMac late 2013, can you help me out? Is it possible considering Yosemite was pre-installed?!

The first pre-installed OS on the iMac14,1/iMac14,2 was Mac OS X 10.8.4. You may install any OS version newer than that one.

If you have any personal data on this Mac, save it to an external drive.

After creating a bootable thumb drive using the Mavericks installer, boot to the thumb drive, erase the main disk and install Mavericks.

Restore your personal data from the external drive. Some of the data (Photos library, probably your Mail data) - if you had any - is not backward compatible with the apps (iPhoto, Mail) used in Mavericks.


17" MacBook Pro (early 2011) 16GB RAM, 1600 MHz? Crucial and OWC both say that the 17" MacBook Pro (early 2011) supports 16 GB. But both only offer 1333 MHz when I select to buy.

Rightnow I've got a single 8GB 1600 MHz chip, have had it for years and it works fine.

Would this model have issues with two 8GB 1600 MHz chips?

Your MacBook Pro has two memory slots designed to take 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM memory chips.

Apple's official position is that this model supports up to 8GB of memory, but real world tests have proven the machine to work fine with 16GB, so both Crucial and OWC are correct in what they say.

If both of them sell the 1333MHz chips, assuming they are 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM memory chips, then these will work as they are the correct specs for your machine. Xaxxon's comment about the likely speed of what your 1600MHz chip is running at is correct. Paying for 1600MHz chips are just a waste of money.

If it was me I would go ahead and purchase two of them and install them into your computer to get the 16GB you want.

You could try just purchasing one and adding it to your machine, but you may be risking inconsistent/random performance issues having one 1600MHz chip and one 1333MHz chip installed simultaneously.

Of course, it's up to you and you could just test this and see how you go. But, if it's cheaper to purchase the two at the same time as opposed to buying one and then another later, I'd just buy the two new 1333MHz chips. Having two identical chips is the safest option.


How can I format-erase my main disk through single user mode? I cannot log into my computer anymore and internet recovery is extremely slow, how can i delete the partition and recover to factory stage with single user mode?
Also would erasing it recover my macos to Sierra? I am having troubles with Catalina right now but I am failing to boot my pc.

I did apple diagnostic test but there were no flaws.

You can't realistically recover your OS to factory state from single user mode.  When you boot into single user mode (assuming you enter single user mode with the old style ⌘-S) you have no GUI and a very minimal set of terminal commands.

If you want to reinstall macOS you need to either boot from an external drive (so the internal disk is offline) or from recovery (which loads a minimal OS into RAM).

If you boot from an external disk could install whatever version of macOS you have - but you would need to download the installer from the app store first.

The version you install from recovery depends on the type of recovery to boot into - see How to reinstall macOS from macOS Recovery

    1. Start up from macOS Recovery

  To start up from macOS Recovery, turn on your Mac and immediately
  press and hold one of the following combinations on your keyboard.
  Command-R is generally recommended, especially if your Mac was never
  upgraded to macOS Sierra 10.12.4 or later.

  Command (⌘)-R Reinstall the latest macOS that was installed on your Mac (recommended).

  Option-⌘-R Upgrade to the latest macOS that is compatible with your Mac.

  Shift-Option-⌘-R Reinstall the macOS that came with your Mac, or the closest version still available.

The simplest would be to restart holding Option-⌘-R if you want Catalina


Adjusting light on MacOS High Sierra I have just updated my MacBook Air to High Sierra but weirdly I cannot adjust the brightness with the keys on the keyboard.

Anybody have an idea why this is happening and how to fix?

Are they set to be function keys - there is the "fn" key - have you tried holding that down and tapping the lighting key?

If that works, then you can change the behaviour in system preferences.

You can check this functionality in System Preferences > Keyboard > Keyboard Tab and check to see if the bottom check box ("Use F1, F2, etc...") is checked


Fonts appear fuzzy when connecting my Mac to an external monitor I’ve been having this issue for a long time and I can’t get my head around it.

When I connect my MacBook Pro 2015 to an external 1920x1080 monitor, the font becomes fuzzy and I get dizzy within a few minutes. I tried all suggestions on the official Apple forums but nothing worked.

What I understood is that the problem lies with how macOS renders fonts at different resolutions. I am understanding that it has something to do with aspect ratios and the fact that each pixel is represented by 2 physical pixels to give the Retina effect.

So my MacBook Pro max resolution is 2560x1600 which gives a 1.6 aspect ratio. A 1920x1080 monitor has a 1.78 aspect ratio. So to my understanding, any external monitor should have a 1.6 aspect ratio to be good for my eyes and to avoid font fuzziness.

I saw people recommending ultra HD monitors but those too have the same aspect ratio as 1920x1080, so how are they supposed to be better?

Can someone please explain what I’m missing here?

You're missing something entirely. There's absolutely no requirement of having a 1.6 aspect ratio on external monitors on a Mac.

As long as you do not configure your displays to be mirrored (i.e. showing the exact same image), then the internal and external monitors are treated as separate displays. The resolution and/or aspect ratio of one monitor has no impact at all on the other monitor.

Regarding the 2 physical pixels for Retina effect, you're also missing something entirely here. An external monitor with a 1920x1080 resolution is not going to be in rendered in Retina mode. That is only for high resolution displays. Retina is not part of the equation here at all.

I would ensure that you have chosen font sizes that are large enough for the display. This should cure "fuzziness". You might also want to double-check with a different monitor to ensure that it is not this specific monitor that has a problem.


Remove one song from iTunes account Can I remove one song from my iTunes account so that it doesn't appear on my iPhone without disabling Show All?

Muse made their upcoming album Drones available for preorder at the same time that they made one of its tracks, Psycho, available for purchase so, instantly, I bought Psycho from iTunes and, later on, preordered the Deluxe Edition of Drones from muse.mu. I then found out that the Deluxe Edition of Drones comes with digital downloads of any singles that have been or will be released which I initially ignored as I already owned Psycho but I later realised that the MP3 file had a much higher bitrate than the iTunes file. So, I deleted the iTunes file but, when I play Drones on repeat. Psycho plays twice because iTunes is streaming the track attached to my account and then playing the local, as you can see here:

The song you bought from iTunes Store is not yet downloaded into your iPhone, but will be streamed from iTunes while playing.

There is no option to cancel the purchase and remove the song - from your iPhone. But you can do that from iTunes, from your PC or Mac. Please refer to this to find more about how this request can be made.

Launch iTunes on your PC or Mac.
Click on your name at the top and select Account Info.
Enter password when prompted.
Click on See All under Purchase History.
Click on the arrow next to the group that contains the
purchase you'd like a refund for.
Click on Report a Problem next to the single purchase you'd like a

Is this ram compatible with iMac 27"? I’m looking to upgrade my iMac’s ram but don’t really know much about what’s compatible and what’s not. Is a ram with following features compatible with it?

Crucial 16GB DDR4 2400Mhz SODIMM CL17 DRx8 Ram (PC4-19200)

Thanks a lot.

General
You selected a DDR4-Generation module in the implementation of SO-DIM which is both matching.
But I am not quite sure about the frequency. DDR4 has two standard frequencies: 2400 and 2666 MHz. Normally 2400 is always supported as default, and the 2666 is optional for higher performance.
However Apple is saying you should use a 2666 MHz for the iMac Retina 5K 27-inch 2019 model.
So you should use a memory module that is a Unbuffered Nonparity DDR4 SDRAM 2666MHz (PC4-21333) SO-DIMM. The brand should not matter.
For detailed information what all that means take a look at wikipedia.

Answer:
You selected a 2400 MHz module which normally should work, but apple seams to recommend 2666 MHz. To be 100% sure buy a 2666.
Suggestion:
You selected a Crucial module, on their web site you can search for your system and list all memory modules that are compatible. Here you can only find 2666 MHz modules. So if you want to stick to crucial you can follow this link. That would be my suggestion because the modules match the Apple specificities and are also sold as compatible for your specific system.

Apple Information
On the web site you can view the specifications for the RAM modules.
Memory specifications (iMac Retina 5K, 27-inch, 2019)
This iMac model feature Synchronous Dynamic Random-Access Memory (SDRAM) slots near the bottom of the computer with these memory specifications:
Number of memory slots: 4
Base memory:    8GB (2 x 4GB DIMMs)
Maximum memory: 64GB (4 x 16GB DIMMs)
Use Small Outline Dual Inline Memory Modules (SO-DIMM) that meet all of these criteria:
PC4-21333
Unbuffered
Nonparity
260-pin
2666MHz DDR4 SDRAM


How can I make my microSD card writable? I have a macbook pro running Snow Leopard.  I have Tuxera NTFS drivers.

I have a microSD card, in an adapter, in the slot.  The "lock" slider is in the "unlocked" position.

'Get Info' tells me the drive is formatted to FAT16.  The permissions panel tells me that I can only read.

Disk utility tells me it's not writable.  (It does this for the volume and also for the higher level Apple SD Card Reader Media)

What do I need to do to change permissions to turn this card writable?

I had a PNY 32gb SD Card. Spent hours trying to find out how to make it re-writeable. Well the answer is simple. The slider on the left side of the card must be "up" (the read-writable position) BUT ALSO the tiny "notch" opposite the slider must be covered with a piece of tape. It's really the opposite of the old video tapes, which we had to break the tab if we did not want anything recorded over it. But I can guarantee you I've bought a lot of SD cards and have NEVER had a card that was write-protected out of the package that required me to do anything but raise the slider on the left side.


Is it possible to enable Legacy FileVault for a network user? I am running Mac OS X 10.8 Server with File Sharing and Open Directory providing home directories to network users, so when users log in their home directory is automatically mounted over AFP.

Is it possible to enable "Legacy" FileVault (FileVault 1) where the user's home directory resides inside an encrypted DMG sparsebundle when the user is an Open Directory user whose home directory resides on a network share?

I know this could be done in 10.6 server for mobile clients but I do not know if it can be done in 10.8 server.

I haven't seen anyone hack together a script to re-implement the FileVault encrypted disk image settings, but I have heard of people using a pre-Mountain Lion machine to make more local users and then migrate them to OS X 10.8.

It requires a second machine (or VM if that is up your alley) but I haven't seen any downsides to moving more FileVault 1 type accounts to new systems other than the obvious downsides associated with those accounts:

backups to Time Machine only run when unlocked
compacting of free space can be problematic
slight slow down and chance of breaking some software that assumes hard coded file paths


deleting single entry from history in zsh -- Terminal Is there a straight forward way of deleting a single entry from the shell history in the "new" zsh shell?

I know fc does not support this and I can't even figure out where Apple now stashes the history file (to cope with multiple terminal sessions).

You can either use:

open $HISTFILE && exit

which usually opens TextEdit (or another default text editor - depends on your environment) and remove the line (and the last temporary line containing something like : 1583100426:0;open $HISTFILE && exit) and save the file ("Save Anyway").

or - if you know some exclusive content of the line (in my example below PASSWORD):

setopt HIST_IGNORE_SPACE
 LC_ALL=C sed -i '' '/PASSWORD/d' $HISTFILE

the first command sets the option to not add commands prepended by spaces in the history file
the second command (prepended by a space!) removes all lines containing PASSWORD from the history file

Both commands won't remove unwanted lines in zsh history files in e.g. Time Machine backups!


Why are text files not supported by Quicklook? So I know some questions have already been asked about this like Is there a QuickLook preview for plain-text files with unknown extensions? and QuickLook for files with no extension or an unknown extension, but those questions are regarding fixes as oppose to Apple's reasoning behind not supporting QuickLook for some file types.

I have many text files that I use with TextEdit, some in .rtf format and some in .txt format. I also have many .docx files for school. I'm pretty sure Microsoft created the plugin for QuickLook to work with .docx files. .rtf files are also supported by QuickLook.

Text files seem like the simplest file type, because unlike .rtf files, they lack elaborate text ornamentation and (sometimes) complex formatting.

Why aren't .txt files supported by QuickLook? Are they more elaborate than they seem, or is there something I'm missing?

UPDATE:
Here's an illustration of what I'm talking about:

Normally, text files are supported by QuickLook. If you have one that isn't, chances are that there is something "odd" about the file, at least from the Finder's point of view.

Try opening the file in TextEdit and then choose "Format" and then "Make Rich Text" as shown here:

http://images.luo.ma/TextEdit-Format-Make-Rich-Text.jpg

Type a space (or modify the document in some other minor way).
go back to the "Format" menu and choose "Make Plain Text" again.
Save the file.
Check to see if QuickLook is able to show the file.


(find: *.png: No such file or directory) terminal I am trying to do some batch processing in terminal with texturePacker. The creator of texturePacker said that this is the way that you batch convert a directory of .pngs to .pvr.ccz.

find <directoryname> -name \*.png | sed 's/\.png//g' | \
    xargs -I % -n 1 TexturePacker %.png \
        --sheet %.pvr.ccz \
        --data dummy.plist \
        --algorithm Basic \
        --allow-free-size \
        --no-trim \
        --opt RGBA4444 \
        --dither-fs

But I keep getting this output in the terminal.
(find: *.png: No such file or directory)
Does anyone know why it would be saying that?

Did you specify the name of the directory containing the files: where the placeholder <directoryname> is? Is there at least one file ending in .png in that directory?

Try with the first part of the command:

find <directoryname> -name \*.png

to see if you get the list of files.


How to run a bash script from the desktop? I have a .sh file with a #!/bin/bash header. I'm able to run it from the terminal, using chmod and ./ but is there a way to perform these two operations from the desktop (i.e. by clicking on it) ?

Btw, I'm familiar with linux, but not with OS X.

You can add a .command extension to your text script.

Then use chmod 744 to make it executable.

When opened or double-clicked in the Finder it will then run from the Terminal.


How do you capture the screen with accessibility features turned on? I'm trying to take a screenshot of my screen with Accessibility display features "Invert colors" and "Use grayscale" enabled, but the resulting screenshot images do not have any of the visual modifications. They appear as if the Accessibility features were turned off. Anyone know how to capture this type of image?

Normal: http://3gfp.com/i/normal.png
Inverted & Grayscale: http://3gfp.com/i/inverted-colors_and_grayscale.png

Update: If I capture a movie with QuickTime or ScreenFlow, I get the grayscale effects, but not the inverted colors. Then, I could grab a still from the movie.

Take the screenshot normally, then open the image in Preview.
Press ⌥⌘C to adjust the colour of the image.
Drag the saturation slider down to the minimum.

Swap the colour positions in the histogram.

  Result:


How would TimeMachine work with two external (destination) drives? I would like to backup my data to two external drives. That way I would like this to work is that both disks should have have a full backup of my internal disk. Is this the way TimeMachine would work?

I haven't tried it, but since mountain lion, it just works.


Skype crash in Mac OS X 10.8.3 I am facing the problem on the login of skype, I've searched on the Skype site and found this link.

However, I'm not able to figure out what causes this issue.

I'm using Mac OS X 10.8.3

Here is the link for the crash report.

Update

Since your report shows crash in Thread 0, it might have to do with some other application is garbing all ports. Disable all programs specially if you using VMware, Parallels, or VirtualBox to see if the problem is there. – Borderline 8 mins ago

Based On the above comment :

I see you found the problem being the call recorder :) I assume skype is looking for it, and it gets refused.

Kill that application, and if you want a new recorder try this one.

My MacBook Air suddenly shut down today, is there an easy way to find the associated log entry? My old 2012 MacBook air suddenly shut down. I had the battery recently replaced by a non-Apple shop since Apple has already obsoleted this model.

The battery was somewhere between 60% and 80% when this happened. I wasn't doing anything particularly power-consuming, WiFi was on but I was just editing some slides (no active browsing or movie-watching).

I plugged the power in and restarted. The date was reset to something in 2018 and the time was wrong. I connected to the internet and let it auto-reset.

I've had this new battery a month or two and it's worked fine until today; I can work offline for ~5 hours and still have ~30% charge left.

Question: I've never looked closely at the console reports before so I don't know how to search for a sudden shut down, possibly due to loss of power. I do know that I had to reset the clock after starting again. How can I zero in on "something bad happened" reports?

Battery Information:

  Model Information:
  Serial Number:    W0137xxxxxxxx
  Manufacturer: SMP
  Device Name:  BQ20Z451
  Pack Lot Code:    0
  PCB Lot Code: 0
  Firmware Version: 201
  Hardware Revision:    000a
  Cell Revision:    158
  Charge Information:
  Charge Remaining (mAh):   7596
  Fully Charged:    No
  Charging: Yes
  Full Charge Capacity (mAh):   7845
  Health Information:
  Cycle Count:  31
  Condition:    Normal
  Battery Installed:    Yes
  Amperage (mA):    333
  Voltage (mV): 8362

You can get the previous shutdown cause from the log history.

In macOS Sierra and later with unified logging:

log show --predicate 'eventMessage contains "Previous shutdown cause"' --last 24h

Earlier than macOS Sierra, filer system.log for some recent results:

grep "Previous shutdown cause" /var/log/system.log

Then look up the code on this table I maintain: Previous Shutdown Causes Explained


iOS9 how to change back to ALL CAPITAL keyboard? After using Apple iPhone keyboard for close to 4 years, I'm quite proficient with typing on the keyboard, almost touch typing, while relying on autocorrect.

The new lowercase keyboard totally throws me off.

How can I get my iPhone with iOS9 to go back to default keyboard where all characters are capitalized?

Go to Settings > General > Accessibility > Keyboard and set the 'Show Lowercase Keys' to off.


Connecting LG27UL850 to MacBook Pro 13" 2015 at 3840x2160 60hz I have just bought the LG27UL850 and plugged the LG supplied hdmi cable in to my MacBook Pro 13" 2015. I can only get 3840 x 2160 (low resolution) at 30hz. I want this resolution at 60hz which I know is possible but I'm not sure how. Does anyone know which adapter will help me do this? Thunderbolt 2 to HDMI? Display port to mini display port? Am i the only one that finds this mega confusing?!

A 4k resolution at 60 Hz over HDMI requires HDMI 2.0, which your MacBook Pro does not support.

Instead you'll need to use the Thunderbolt 2 port with a mini-DisplayPort to DisplayPort cable, which supports 3840x2160 at 60 Hz.
