After installation of new SSD, Macbook Pro 15" Retina won't wake up after it goes to sleep mode

That can happen with non-Apple SSD-sticks, even Apple ones from the wrong year's model can cause those exact symptoms. You can't take one from a 2015 MBP 15 and attempt to use it in a 2013 model, although it will work in the 2014.

You'l just have to find the right one for your exact model; Transcend's JetDrive line of SSD-sticks for Macs are well delineated on their product site.


What is the source of the Earth and Moon wallpaper?

It is clearly a Photoshop creation, as the shadows do not concur to the actual position of the celestial objects.


Can I create a self-extracting archive for Mac?

OSX contains an unarchiver so you don't need the equivalent of a .exe so you can extract on any machine and not be stuck as you are on a Mac when you receive a Windows self-extracting archive

To archive select the files in Finder. Command-click or right-click and choose compress from the menu - you will get Archive.zip. To unzip just double click on the .zip file

The tool that does the unarchiving is Archive Utility.app and understands various compression schemes from Wikipaedia including bzip2 which can be better than zip - but you need to compress using a command line tool bzip2


Kindle App Store linkDid you try the official Kindle app? It is a universal app (for iPhone and iPad)


No, the Photos app does not offer a computed "Uploaded" folder that automatically gathers all photos ever uploaded across services.
There's also no other place in the system, nor any log file in the system, that automatically gathers a list of photos uploaded to services via apps on the device.


System Integrity Protection — Is it implemented in Darwin? Or is it OS X only?

SIP is exposed to the file handler code as a new "restricted" class flag ACL as if it were stored in the file system metadata, so the code required to prevent all writes would be fairly transparent to implement so that all other packages would just get an enoperm error if my suspicions are correct.

You are correct that we don't have a source dump yet for 10.11 so I reserve the right to be totally wrong about my suspicions.


Exporting or Viewing Apple Watch heart rate info

On the main screen for health data there is an icon in the upper right (mine is a red silhouette of a person). If you press this icon the next screen gives an option to export data. It is easy to import data into Excel as an XML file. From there you can use normal Excel commands to filter, create charts etc.....


stat command not respecting time format options (High Sierra 10.13.6)

You need to place a S before B which converts the numerals (seconds since epoch) into string output.

stat -f "%SB" -t "%Y-%m-%d" ~/Pictures/to_backup/IMG_2115.JPEG


You can use the following to open Octave with a file:

open -a "Octave" /path/to/file

If you want, alias this to octave by adding this line to your ~/.bash_profile:

alias octave="open -a \"Octave\""

Now you should be able to use octave /path/to/file anywhere.


I want all visited links to have the same color

In Safari you can create a custom style sheet and import it in Safari:

E.g. in Terminal enter:

echo 'a:visited { color: red !important; }' >> ~/Library/Safari/link.css

Then open Safari > Preferences > Advanced > Style Sheet > Other... and choose the links.css.

In older Chrome versions you can modify the file ~/Library/Application\ Support/Google/Chrome/Default/User\ StyleSheets/Custom.css (usually a 0 Bytes file) and add the same line:

echo 'a:visited { color: red !important; }' >> ~/Library/Application\ Support/Google/Chrome/Default/User\ StyleSheets/Custom.css

The support for custom stylesheets has been removed in newer Chrome versions. Here I recommend an extension: Stylist.


Terminal won't open after brew upgrade (dyld library not loaded)

Install iTerm.app You can set up a profile that you can set the start up program do be /bin/bash

Or create a new admin user and use that to restore or reinstall files. I think you might be able to use dscl from that user to change the original users' shell


Incorrect amount of free space on 2009 Macbook

You appear to have a heavily-used computer with a 5-year-old drive. I would be more surprised if it didn't have issues.

Two things you can try:

Step 1. Clone your drive to an external drive using something like Carbon Copy Cloner. Do NOT use block copy mode or Disk Utility, that copies the problems as well.

Step 2. Boot from something else, like the clone, reformat your internal drive and clone back (you can use block copy this time).

If that doesn't solve the issues, your drive has hardware problems. Replace it with an SSD and your issues will go away, plus you will get a huge speed increase.


Can we open/run a file/executable in Finder using the keyboard?

On macOS, to open the selected item, press:

Then space again to close Quick Look.


OSX Installation to MBA (Macbook Air Model A1370) SSD upgrade

Unfortunately, it is not possible to install an M.2 SSD into a MacBook Air (or Pro), because Apple SSDs aren't M.2, and (please correct me if I'm wrong) there are no Apple SSD to M.2 adapters, partially because (this is what I've been told) an M.2 SSD has to be directly mounted to the motherboard. Also, it's quite possible that M.2 SSDs are different dimensions than an Apple SSD, and might not fit in the (computer's) case.

You can however buy an Apple SSD from OWC, which should work perfectly with your MacBook Air.


What's the best OSX for my 2007 3.1 MacBook 2.2Ghz Intel Core 2 Dual, 1GB RAM, currently using OS X 10.5.8?

According to EveryMac the latest OS that your Macbook can run is 10.7.5 (Lion).

A big focus on the preceding release 10.6 (Snow Leopard) was performance. It was the OS update that Apple advertised as having "no new features" as the work was focused on refining and improved the existing ones. Reducing the memory footprint, removing legacy code, the Finder was rewritten in Cocoa, a new Cocoa version of Quicktime was created, etc. In John Siracusa's review of Snow Leopard for Ars Technica he said "Should you buy Mac OS X Snow Leopard? If you're already running Leopard, then the answer is a resounding 'yes.'"

So I'd definitely recommend upgrading to Snow Leopard at least.


Right after you accidentally delete the note, give your iPhone a quick shake and it will prompt a message asking you if you want to undo the last action.

Here is some more information about this feature. (It also mentions that you can restore the OS from a backup - assuming you've synced recently)

Also, there is already another Post that addresses this issue. You might want to look into that as well.


Does Time Machine run backups even when no account is logged on?

Time Machine is a system-level daemon, not a user-level process. Time Machine will work even if you are not logged into your Mac.


Preventing desktop jump when window is open on another desktop?

At least on El Capitan, it is (apparently) necessary to restart the Dock after setting the value of workspaces-auto-swoosh

On the command line:

defaults write com.apple.dock workspaces-auto-swoosh -boolean NO
killall Dock


Generally, even when the actual song files are located on another drive like you state yours is, the iTunes library is still in the ~/Music/iTunes folder on your main computer drive. You can usually get there in Finder by clicking on Music in the sidebar.

Copy the above folder (iTunes) from your old computer to your new one, making sure to put it in the same place. If you already opened iTunes on the new computer, there will probably already be an iTunes folder there, and it's okay to drag it to the trash.

Once you've copied the folder over and you plug in your external hard drive, open iTunes while holding the Option key on the keyboard. When you see a message that asks you to Choose iTunes Library, click Choose Library. Navigate to the Music folder and select iTunes. At this point it may take a few minutes for iTunes to load, depending on the size of your library, but everything should be in place.


Macbook Pro Retina 13" performance for designers

If you can handle going from a 27" screen to a 13" screen (even though it's retina, the 'apparent' resolution is set quite low), then the rest of the system is fast.

Of course, you would want as much RAM and SSD as you can afford (you can't upgrade it later), but there is nothing to worry about with the CPU or the SSD speed.

In fact, the SSD alone will make it seem SUPER fast compared to a 3-4 year-old iMac (assuming it didn't have an SSD in it also).

If you needed an external GPU, then your only laptop Mac option these days is the top-end 15" Retina MBP, but that's larger and quite a bit more expensive than the 13" models.


You can also use Ethernet to connect to a Time Capsule with Wi-Fi disabled.

Connect Time Capsule and Mac via Ethernet cable.
Launch Airport Utility. If Wi-Fi on the Time Capsule is disabled it will show up with a yellow warning sign. Clicking on it only offers to 'Forget this device'.
Click on 'Other Wi-Fi Devices' in the top left corner and under 'Network Interfaces', choose 'Ethernet'.

The Time Capsule should appear. Clicking on it now allows to change its 'Network Mode' by first hitting 'Edit', then choosing the 'Wireless' tab, followed by selecting Wi-Fi from the dropdown menu. Applying the settings will take a few seconds and require a restart.


How to make Airmail to open mailto: protocol link?

I use RCDefaultApp to tweak this type of setting and many other.  Note that while this is an older app nonetheless it still works with OS X 10.11.x too.

It's a Preferences Pane style app and it's freeware. You can read more about it and see screenshots at the web site (linked above).


Uninstalling NTFS-3G and MacFUSE after upgrading from Yosemite to El Capitan

In order to remove MacFUSE, you can following this guide. So:

Access the root account: sudo su
Execute uninstallation scripts:

/Library/Filesystems/osxfusefs.fs/Support/uninstall-macfuse-core.sh
/Library/Filesystems/osxfusefs.fs/Support/uninstall-osxfuse-core.sh
/System/Library/Filesystems/ntfs-3g.fs/Support/uninstall-package.sh

Additionally you can remove files and directories, that uninstallation scripts don't remove:

rm -r /Library/PreferencePanes/MacFUSE.prefPane

(to remove the button from the preferences)

rm /Library/Preferences/com.google.macfuse.plist
rm /Library/Logs/ntfs-3g_util.log
rm /Library/Preferences/org.catacombae.macntfs-3g.DriverSettings.plist
rm /Library/Preferences/org.catacombae.macntfs-3g.DriverSettings.plist.lockfile
rm /private/var/run/ntfs-3g_daemon.pid
rm -r /private/var/root/Library/Caches/autoinstall-macfuse-core
rm -r /Users/admin/Library/Caches/com.github.osxfuse.OSXFUSEPrefPane


show battery in prompt and have it update after every command

You have to escape it, if you want it to rerun every time it gets called. It can easiest be done with the dollar-sign.

_PS1battery="\$(battery_status)"


Putting files outside the user/home folder

If you create (or rename) a folder at the root, OS X will ask for your password. This is because you do not own the root folder. Once the folder exists, you can copy (or add) as many files and folders to it without having to enter a password. In terms of permissions, the only difference, between such a folder and your home folder, is the home folder has an Access Control List (ACL). Entering the command ls -led ~ in a terminal window results in listing the home folder's permissions. On my computer running OS X 10.10.4, I get the following output.

Davids-iMac:/ davidanderson$ ls -lde ~
drwxr-xr-x+ 20 davidanderson  staff  680 Aug  6 21:51 /Users/davidanderson
 0: group:everyone deny delete

The ACL is group:everyone deny delete. I assume denying everyone delete permission prevents the deletion of your home folder.

One small point, normally your files are assigned to the group named staff. If you create a folder in the root folder, the group will be wheel instead of staff. You can correct this by typing the command chgrp staff /newfolder after creating the folder. Substitute your folder name for newfolder.


Does Mavericks have a GUI for NFS mounts as in previous OS X versions?

A late answer, for posterity and the desperate searcher.

The GUI has been moved more or less to Directory Utility, which can be found in /Volumes/[name of your harddrive]/System/Library/CoreServices/Applications. Use -shift-G if you are lost to find your way.

Open Directory Utility and click on the Directory Editor (third) icon.
Select "Mounts" from the dropdown menu Viewing (Node dropdown menu set to "/Local/Default") - if editing is locked, click the lock and enter an admin password.
Click the + icon in the lower left corner of the pane to start a new entry. Set "record name" to the server directory that you want connect to: [IP of server]:/[level1]/[level2] ….

Click "Save"

Click the + icon in the right half of the pane, to add (and save) the values for
VFSLinkDir (full path to the mountpoint, that is, where the remote directory should be inserted), VFSOpts (I am using resvport,nolocks,locallocks,intr,soft,wsize=32768,rsize=32768,nosuid) and VFSType (nfs). The values for AppleMetaNodeLocation and GeneratedUID are generated automatically.

Restart your computer.

Note added: After changing the NAS system I noticed that the above instructions worked with a Seagate BlackArmor NAS, but not with a WD MyCloud Mirror NAS. The WD NAS can be mounted as a NFS share under OS X 10.6.8 without problem. For a working connection with the WD NAS I used the following options: resvport,nolocks,locallocks,nosuid,rw,no_root_squash,no_subtree_check,soft,intr,rsize=8192,wsize=8192,timeo=900,retrans=3,proto=tcp,all_squash (I copied these from another site, maybe not all of them are required).

It is failing to write the partition map on the flash-drive (step before formatting the filesystem) in order to do anything with it, so should be in a safe place to force-quit disk utility.

How to hide xattr lines from "ls -l" output

The ~/.bashrc file had an alias that made that the default. I removed the alias and the extra lines were gone.

The line in my .bashrc file read: alias ls='ls -FGhO@.

Remove the "@" and problem is solved.


ClamXav

It is open source and low resource consumption, but is not free.

There is also a free command line version available in brew, fink, and macports under clamav (less ugly).  There is some minor configuration, but there are decent guides on the ClamAV site and here, for example.


In the app, go to tab More. Then Settings → Sound and disable In-App Sound.


How to change resolution when using screen sharing and no physical screen is connected?

There is a very cool command line utility called cscreen. The developer has a number of versions available. Depending on how old your Mac is, you either want the PPC version, or the Intel version. If your Mac is newer than a 2006 model, you probably want the Intel version.

Once you have downloaded the disk image, double click the image to mount it, then copy the cscreen file to anywhere except the disk image. Now open Terminal. (You can search for it in Spotlight.) Once Terminal is open, you can run cscreen by navigating to it, then typing ./cscreen. For example, if you copied cscreen to your Desktop, you would navigate to the Desktop in Terminal by typing cd ~/Desktop. Once there, you would type ./cscreen.

To change the resolution, we first need to know what resolutions are possible. To find out, we can type ./cscreen -v. This should output something like this:

Now we can choose a resolution. Assuming you want 32 bit colour depth, you can change to the resolution of your choice by typing

cscreen -i <DisplayID> -d 32 -x <width> -y <height>,

and replacing the parts enclosed in <> with the actual values. I haven't tested this with a headless system over VNC, so your milage may vary. The command line option -i <DisplayID> is optional, so if your VNC doesn't register a display ID you may still be able to change the resolution if you omit that part of the command.


Does iPad mini 4 also feature the new and faster 2nd-Generation Touch ID sensor featured in the iPhone 6s?

Apple's iPhone 6s website has a section about Touch ID on the Technology page. It says:

  Touch ID lets you unlock your phone and make purchases with Apple Pay simply by using your ﬁngerprint. It uses highly sophisticated algorithms to recognize and securely match your ﬁngerprint. And the improved Touch ID sensor detects your ﬁngerprint even faster than the previous generation.

By comparison, the iPad mini 4 has a whole page about Touch ID, but it never references a previous generation that's been improved upon. That leads me to think that the iPad mini 4 doesn't share the iPhone 6s's Touch ID 2 technology.


I would assume the repair technician has total control over your files since he or she controls physical access, can remove the storage and image it, knows how to reset passwords, make secondary admin accounts, etc.

Most technicians have high standards and should explain the procedures they will take to guard your data, but you'll still be extending trust to someone with the training and opportunity to make a copy of your data and/or poke around.

As to observing them, unless you reported a software problem and they are going to fix your software, you won't learn anything by logging the keys pressed.

They will use their computers to do research and likely boot off their software to see if your problem is your settings or your particular copy and version of the OS.

If you install audio or video recording software, you may want to get legal advice since you don't want to break any laws spying on them. Again, check the terms of service - you will likely be granting them permission to erase, modify and inspect your computer when you hand them the hardware.

If your goal is to track what they do, why not ask them to provide you with steps and then check their work by running tmutil compare to see which files changed after service from a backup that happened before service?

I've never found key loggers to be useful and other recording software is buggy and slow IMO.

What I do is delete the drive entirely and give them a test account or use FileVault to encrypt everything you care to "watch" and just not give them the password or key to decrypt the volume if for some reason you din't want unauthorized access.


There is nothing wrong with the Boot Camp Assistant. The problem is with the use of APFS. If the APFS configuration is not precisely correct, then the Boot Camp Assistant fails. Eventually, your macOS installation can boot and preform correctly without you knowing there is a problem with the APFS configuration. In such cases, problems first appear when trying to repartition using the Disk Utility, Boot Camp Assistant or the command line.

The stock solution is to backup using Time Machine, then reinstall everything from scratch. The result is a clean system where the Boot Camp Assistant correctly installs Windows on your Mac.

An alternate solution would be to use the Boot Camp Assistant to only download the Boot Camp Support Software (Windows Helper Software). You then would install Windows using a USB flash drive. An example of such a procedure is outlined in the accepted answer to the question "Can I install Win 10 (GPT formatted USB installer) on MacBook Pro without using BootCamp?". In your case, you have already allocated space for Windows. I would recommend modifying step 7.1 to include deleting the OSXRESERVED partition, then using the remaining free space for the Windows installation.

If you want to forgo a Windows installation, them the following commands should recover the lost space.

diskutil eraseVolume free n disk0s3
diskutil apfs resizeContainer disk0s2 0

If the above commands fail to work, then you will need to boot to Recovery Mode and enter the following commands. These commands will not alter your computer. The commands just shows the internal partition table values. Post the results to your question.

sudo fdisk /dev/disk0
sudo gpt -r show /dev/disk0

Apparently, there is some distinction between the command line tools installed for use by Xcode and the tools installed for system-wide use:

https://github.com/Homebrew/brew/issues/5002#issuecomment-425707878

For my machine, running xcode-select --install and choosing to install the tools from the window that popped up helped fix the problem. I was able to confirm that it was fixed when running brew config and seeing a valid entry for CLT:

CLT: 10.0.0.0.1.1535735448
Xcode: 10.0


How do I delete my notes on one device without deleting them from iCloud?

Switching back to mac os from Ubuntu Problems

Yes, when you installed Ubuntu, you overwrote the partition named Macintosh HD. You will need to recreate this partition before installing macOS (OS X).

You can use the Disk Utility application to erase your drive. For name, use Macintosh HD. For the format, use either Mac OS Extended (Journaled) or Mac OS Extended (Journaled, Encrypted).

Sometimes when the previous operating system was Linux, this can fail. If so, perform the steps given below.

From the menu bar, select Utilities→Terminal.
In the Terminal windows enter the following commands.

diskutil  unmountdisk  disk0
diskutil  erasedisk  jhfs+  "Macintosh HD"  GPT  disk0

Quit the Terminal application.
If you want encryption, use the Disk Utility application to erase the drive again.
Install macOS (OS X).

Note: If you install or upgrade to High Sierra and your internal drive is a SSD, then this drive will probably to converted to use the new Apple File System (APFS) format.


Cannot add keyboard shortcuts in Mountain Lion

On the screenshot the panel with more choices is completely withdrawn (on the left). Once you pull it out, it makes it possible to select "Application Shortcuts" and then a "+" button appears which provides the sought functionality.

Bottom line: don't lose your panels!


How Do I Know When I am in Private Mode?

In Mojave, the address bar has different shades of gray/black depending on whether you're in private mode or not.

In light mode it's light gray for not private, and a dark gray for private mode.

In dark mode it's black for private, a fairly medium gray for not private.


I deleted my Bootcamp partition but can't resize my OS X partition

Quick fix:  Fake Bootcamp.

"I partitioned the free space (that OS X couldn't use) as MS-DOS, Bootcamp Assistant thought it was Windows, and was able to remove this MS-DOS partition and restore Mac OS to a single partition."

This is the easiest solution, so try that first.

No luck?  Long fix:

In my case, I couldn't get Disk Utility to create the partition.

I tried using gpt to recreate the partition, but it wouldn't write to the GPT while any of the partitions were mounted.  But since it's my boot partition we're talking about, the disk was in use, because one of the partitions (my boot partition!) is mounted.  So we need to boot from not-this-disk, and unmount all the partitions on the disk, and then use gpt.

Internet Recovery

Boot to Internet Recovery  (hold Cmd+Opt+R during startup), so that the disk will not be in use.  If your machine is too old for Internet Recovery, you should be able to boot from another disk (not another partition) and get the same result.  Note: in this case that the disk numbers (/dev/disk0) may be different for you.

Start Internet Recovery, and go to Utilities -> Terminal.

-bash-3.2# gpt show /dev/disk0

This is the space I want to reclaim.

As a sanity check, take the size (second column), multiply it by 512, and divide by a billion.  The result should match the size of your former Bootcamp partition in GB.

Example: 58593759 * 512 / 1,000,000,000 = 30 GB

Take the start position (first column), that's where we'll tell gpt to make the new partition, with

gpt add -b <start position> -t windows /dev/disk0

In my case, you can see that the start position is 431640960.  You can and should select/Copy/Paste in your own Terminal to get this number copied correctly.

Example: -bash-3.2# gpt add -b 431640960 -t windows /dev/disk0

/dev/disk0s4 added

Finally!

If you got an error No such file or directory, read the next section, and then come back here and try again.

Assuming you got the disk added ok, reboot and use Disk Utility to erase the new partition as MS-DOS.  Run Bootcamp assistant and choose Remove Windows 7.

  Bootcamp has been removed and your disk has been restored to a single volume.

And all it took was my whole day.

unable to open device '/dev/disk0': No such file or directory

When you use the gpt add command, you might get the error

  unable to open device '/dev/disk0': No such file or directory

This message is very confusing.  We just read that device earlier with gpt show.
This message really means "device is in use".

OS X Recovery may have mounted it, and you have to unmount it.  Use the mount command to find your mounted partition and umount it.

-bash-3.2# mount

will produce a huge list of partitions:

/dev/disk2s3 on /
devfs on /dev
/dev/disk3 on /Volumes
/dev/disk4 on /private/var/tmp
/dev/disk5 on /private/var/run
/dev/disk6 on /System/Installation
/dev/disk7 on /private/var/db
/dev/disk8 on /private/var/folders
/dev/disk9 on /private/var/root/Library
/dev/disk10 on /Library/ColorSync/Profiles/Displays
/dev/disk11 on /Library/Preferences
/dev/disk12 on /Library/Preferences/SystemConfiguration
/dev/disk13 on /Library/Keychains
/dev/disk1 /Volumes/Macintosh HD  <--- unmount this /Volumes/<YourDisk>

-bash-3.2# umount /dev/disk1

It will periodically be remounted automatically, so try to hurry or you'll have to unmount it again.


Changing the email shouldn’t make a difference. If you delete the account and make a new one backup information could be lost.

From this Apple Discussion:

  When you delete the account and choose Keep on My iPhone (iPad), contacts, calendars and other synced data will remain on your device.  When you sign in with your new ID to create your new account and choose Merge, these will be uploaded to your new account.  Synced notes and photo stream photos are exceptions to this, which is why you have to take steps to save them prior to deleting the account.


A good iPhone app for it when standing in the dock

I'm using Alarm Clock (there's a free version, but with an ad on the bottom, so not very "beautiful").

It shows the time of the day (obviously) and can also show the date, and the weather/temperature.
Nice touch: sliding your finger increase/decrease brightness.

(But no social network)


If you want to watch Netflix on your Mac, the best way to go is just use Netflix.com (you'll need the Silverlight plugin).

AppleTV doesn't have any capabilities to send streams (ala AirPlay), just receive them from other devices. The reason for this is effectively that the Apple TV doesn't really hold any content. It sources it all from other places, all of which can be accessed from your Mac (i.e. iTunes, Netflix, Hulu, etc.).


How to convert non-utf8 encoding to utf-8 encoding during unzip?


Adjusting graphics cards settings in Mojoave to reduce overheating with external monitor (MacBookPro2018)

The 2018 15" MacBook Pros all have dual-GPUs. The AMD GPU is required to be active when an external screen is connected. There is no way to use the internal (Intel) GPU for external screens.

Fan noise is one of the main nuisances of the recent MacBook Pros in my opinion. When I get too frustrated, I sometimes use Turbo Boost Switcher, which helps a bit. Volta is a similar App, but does not seem to work with 2018 MacBooks. Both Apps deactivate the CPU's Turbo Boost mode, which means less speed, but also less power consumption and less noise.

Update: I forgot to mention AppTamer; another tool which often saves me some noise.


iOS 9: How to disable Location Services for specific apps?

You can still do that.
All you have to do is:

Opening Settings > Privacy > Location services

Now here you can either disable/enable completely the location services, or limit the access to some of the Apps you choose, it's all up to you.

Thus, if you want to disable the geotagging in your photos and videos you'll want to disable the Camera option from this list.

Hope it helped you out!


How do I remove Finder tags from all files in a folder and its subfolders?

You can use Homebrew's tag:

brew install tag
tag -r /path/*

You can combine this with a find command to find specific files/folders + recursive.

find . -exec tag -r {} \;  -print


Mac after reboot only allows one account to logon

FileVault is the clear case where the system will boot to a pre-OS screen and show you only the file vault enabled accounts. When you sign in and authenticate as one of these accounts, that unlocks a decryption key that allows the OS to be readable and starts the actual OS boot process.

You can determine which accounts have been enabled in FileVault by examining that system preference once you’re logged in to the running OS.

Since you managed MDM and JAMF - here is an article with great technical data on the need for a secure token to be provisioned for each FileVault enabled account:

https://derflounder.wordpress.com/2018/01/20/secure-token-and-filevault-on-apple-file-system/

Your IT team should investigate JAMF Connect which extends the typical log in screen to let any AD allowed account log in. It also can be provisioned so that membership in an AD group maps to an admin local account or a non-admin local account. It’s an amazing tool and far better than binding which can have many down sides.

Can I restore a system upgrade from a Time Machine backup?

Unless you excluded the OS files from the backup, Time Machine should've backed that up along with everything else; but in order to recover the entire OS (rather than just your user files), you have to do the restore differently: use the restore tool in Recovery Mode (reachable by starting the Mac with Command and R held down). However, there are a couple of warnings I should give about this route:

I haven't tested it, but I think this form of restore will wipe out everything currently on the disk, replacing it with the earlier backup snapshot. Have you done anything important since the backup? If so, you should back that up before going this route.
If you'd excluded any files/folders from the backup, they'll be missing from the restore as well. It's fairly common to exclude the OS itself from backups, so if you'd done that this form of restore will not give you a bootable system.

Because of the above, I'd be inclined to stick with the restore you have, and simply reinstall the update.

BTW, the question seems to contain a bit of a misunderstanding about how OS updates and backups work. Time Machine (and other backup systems) back up files and folders. An OS update isn't a file or folder that can be backed up as an item; instead, it's a bunch of changes to various system files and folders. If those files and folders are being backed up, the updated versions will be backed up; if not, they won't be. Similarly, you can't restore a system update, you can only restore the changed versions of the various system files (and since you don't know precisely which ones were changed, that pretty much means restoring all of the system files and folders).


How can I save Keynote presentations as an auto-playing slideshow?

The way this is done with Keynote is somewhat different to the PowerPoint approach.

Instead of having to save the presentation as a different file, you only need to change your presentation's settings within the Inspector.

Assuming you're talking about the latest version of Keynote on macOS, follow these steps:

Open your presentation in Keynote
Click on the Document icon at top right of the toolbar
Under Slideshow Settings, tick the Automatically play upon open checkbox
In the Presentation Type drop-down menu,  select Self-Playing
Now save your presentation

Now when you open it up it'll automatically play in presentation mode.

NOTE: Obviously you can play with these settings if you'd like to achieve a different outcome.


“SQLDeveloper.app” fails to open after upgrading to Big Sur

Launch terminal app

Run the following command to list your Java Versions:
/usr/libexec/java_home -V

From the output, the one that is causing the issue is:

"Oracle Corporation" - "Java" /Library/Internet
Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"

You'll need to remove this by typing in the following command:
 sudo rm -rf "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/"

Verify the currently set java_home path and update it as per sqldeveloper version you have installed
sudo vi $HOME/.sqldeveloper/20.4.0/product.conf

Add following entry if its not already added (you may need to change as per version)
SetJavaHome /Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home

Working fine for me with sql developer 20.4 on Mac OS Big Sur


No, just had a fiddle and it appears there is no way to do that.

Neither of these work:

In terminal:

open .

will open the current directory in Finder.

Unhiding it with:

sudo chflags nohidden dirname

Does not work either. (Error --> chflags: dev/: Operation not supported)


What is the relevance of "Low Signal" in battery usage stats?

You’ll see “low signal” when you are using service in a poor reception area. When the phone needs to search for a signal all the time it uses more battery life. We normally see this on Home & Lock Screen and Personal Hotspot. The best thing to do to save battery in these situations is look for a way to get a better signal, or maybe even turn cellular off when you are in really bad reception areas. You can turn off cellular by going to Settings -> Cellular -> Off. With this off you can’t make calls, so you don’t want to leave this off all the time, but it can help in some situations.

"Better" is relative so the percentages would probably vary by situation.


How to connect to wifi from single-user mode?

To my knowledge this is not possible as the necessary services/daemons that enable networking don‘t start in single user mode.


External Thunderbolt drive and Monitor from same port?

Thunderbolt as a technology supports daisy-chaining devices (connecting one device into another). Unfortunately a number of the devices available like the 2.5" GoFlex adapter and the video converters don't have the second port to allow this.

Your option could be to get the 3.5" GoFlex adapter and mount your drive in that and connect the screen to the second port on that.

There are some HDMI splitters on the market but this will just send the same image to each screen.

Apple Enterprise account taking too much time for verification

If you don’t get an initial status after 15 business days, it might be worth checking in with developer support to check if you can help clarify anything. With the recent news of large companies that should have known better being publicly caught using enterprise certificates to surveil non-employees and minors, I would only expect the requirements to qualify for enterprise accounts to get more legalistic and involve more paperwork. Also, there’s not much reason to go enterprise anymore so make sure you even need that capabilities before you undertake the vetting process.

On the good news, I’ve been seeing Apple just decline enterprise accounts and tell people to get a normal account. If Apple hasn’t offered that, I would reach out to the sales channel that took your money and/or developer relations (if you have a personal account) to check if you can submit any information to speed their review.

If they see you as a legitimate business and you have submitted more than a handful of apps through TestFlight then it will be far easier to make the case you are an enterprise. I would expect Apple to make a formal change to say that a requirement for an enterprise account would be to have three individual accounts submit apps to show that you’ve outgrown the normal developer path. You don’t have to release anything on the app stores publicly to show you’re an enterprise and submitting honest builds - everything can be internal testing.

I would expect that the number of enterprise companies that don’t have an account at this point is so low, the majority of applications are not truly enterprise 10 years in to this process.

I tried to enroll my company to Apple Enterprise program, but get message "Cannot enroll in Apple Developer program"
How to appeal rejection by Apple for Developer Enterprise Account?

My answer to the second question above has one public report of this shifting enterprise apps to normal accounts going forward. Time will tell if my hunch is right or if you just need your legal and business departments within the enterprise to contact Apple to show you have several developers and need of enterprise capabilities.


Is iMovie available on the MacBook Air 11 inch?

How to force quit Applescript app from terminal?

Try this:

ps auxwww | fgrep -v fgrep | fgrep -i LightsOn

That should show you the matching process information.

You can also try pkill which should work like this:

pgrep -fl LightsOn

If that shows you the PID, then you can move on to pkill:

pkill -9 -f LightsOn

When you run pkill -9, you're not telling the application to terminate itself, instead you're telling the OS to stop running the program, no matter what the program is doing.

When app gets stuck sending the kill without specifying the signal #, it will automatically assign to it the signal <15>, which means asking the app to terminate it self, it can not do that while stuck.

Which 15 inch macbook with USB has the highest repair score?

iFixit.com has an entire blog about repairability scores:

Laptop Repairability Scores

It's sorted by score from highest (easiest) to lowest (most difficult) or by release date (most recent first).  It includes all makes and models, not just Apple, so if you're looking for an Apple centric list, you'll need to extract the data manually.

IMO, this is an exercise in futility.  Why?

MacBook Airs from 2012 have not only soldered in RAM, but the drives are proprietary making them expensive.  These are the only ones that currently (as of this writing) have SSDs that technically can be upgraded.
MacBook Pros from 2013 on have soldered in RAM and proprietary SSDs as well
2015 MacBook Pros are the only ones with a removable SSD and without the problematic butterfly keyboard
After 2016, you're getting the butterfly keyboard, soldered in RAM and SSD and USB-C

So, if you want high repairability and no USB-C, you're looking at a 2012 model which makes it 6+ years old (soon to be obsolete).  Every manufacturer is going USB-C/Thunderbolt 3 so it's much more economical to just bite the bullet and get a dongle.


Airport Router DHCP Client Identification

It seems there is no way to force a client ID at the router end, so you have to make do with setting it right on the client.  I discovered that my Apple TV and Playstation has spaces in the names that prevented them from setting the ID properly.  Taking the spaces out made them show up properly.  However, some clients manage to register names correctly with spaces, so I guess it's down to the implementation of the IP stack on the client device rather than a server issue.

It's also worth noting that after updating settings or resetting the routers, it appears to show just MACs until it has time at some point doing a lookup against it to set the ID.  I found no way of working out how long this is, seems to be random.

It's also worth noting that some devices that are able to use Wake On LAN over wifi and that are currently in a sleep state will register at a Physical layer, so the router is able to send the relevant command to wake it, and as such the MAC is shown, but no IP (and hence no active DHCP use to pull the ID) until the device wakes and pulls it's IP/registers it's client ID.

Finally, using an old version (5.6.1) of Airport Utility it is possible to view a DHCP lease list of all clients, not just active wireless connections.  Sadly it doesn't work on Mavericks, but you can bodge it to make it work.  Unfortunately, either it does not track the DHCP leases for the guest network, or the lease length (not configurable) is short so pretty much only actively connected guests are shown in this list.


How to make a bootable disk from an image with Toast?

Toast:

"Do not mount the Disk Image first!"
Launch "Toast.app"
Click "Data" icon (upper left) and choose ISO 9660
Select "Copy" icon (upper left) and choose Image File
Click "Select" and "Choose a Disk Image File" from the dialog (do not drag and drop).
Click "Burn" et voilà.

Disk Utility:

Launch "Disk Utility.app"
Click "Burn" icon (upper left)
"Select image to burn" from the dialog (do not drag and drop).
Insert CD / DVD
Click "Burn" using the dialog.

Most effective Option:

Launch "Terminal.app"
Use the following command(s). Replace "imagefile.dmg/.iso" with your dir and/or prefferd name.

hdiutil convert imagefile.dmg -format UDTO -o imagefile.iso
hdiutil burn Imagename.iso

This method uses the exact pre-installed function of "Disk Utility.app" only without the GUI!


Can I get any info about my iTunes Connect customer?

I don't clearly understand if you're using iOS or OS X, but you should receive a receipt from Apple servers with a lot of information about the transaction, including info about the customer. You need to validate this transaction in order to confirm an in-app purchase. more info : https://developer.apple.com/library/ios/releasenotes/General/ValidateAppStoreReceipt/Introduction.html


Select "Sent Items" on Outlook with Keyboard Maestro

Selecting Intractable GUI Elements with Keyboard Maestro

This is one of the most useful aspects of Keyboard Maestro, the ability to manipulate a GUI which is not easily accessed by other scripting options. I'll explain how to use this routine to solve your question, but it can be used for just about anything else.

The recycable core of the method is a sequence of three actions:

Find Image on Screen.
Use Variable in the to set the mouse location mode.
Move or Click Mouse relative to the current mouse location.

Once these three actions are dragged into your macro, you'll need to configure them slightly:

Take a screenshot of the graphical element you would like to select using ⌘-⇧-4.
Drag the screenshot into the Find Image on Screen box.
Test it by hitting try with the Display box checked while the icon is on the screen.
Make sure the same Variable is both set by Find Image on Screen and used by Use Variable.
Adjust the → and ↓ distance so that the button is pressed, in case the image found is slightly larger than the hitbox.

And there you have it. This little block of actions is completely modular, so try to think of other fun uses. Here's my final macro:

How do I avoid update checks for third party software (cobook), dont want to "update" by mistake

The MAS receipt is designed just so you can't do that - otherwise you could hand the app to all your friends without them having to buy it ;-)

Wifi turns off and refuses to turn back on on MacBook Pro Retina with OS X El Capitan

My AirPort Wireless card was broken

Turns out a spider crawled into my computer, nested itself under the wireless card, and died in direct contact with the wireless card. Go figure. The guy who looked at it said there was water damage (ew), and, after disabling the wireless card (software-wise), my crashes stopped as well.

The crashes were the main reason for him to suspect that the wireless card had issues, because the kernel was throwing fatal errors all over the place. If this happens to anyone else (and you know it's the wireless card), what you can do is the following:

Open Terminal.
Use ifconfig to turn the wifi interface to down (should be en0, so using sudo ifconfig en0 down should work)

This makes the computer stop querying the faulty device.

Go to Network in System Preferences.
Remove the Wi-Fi interface (hit the minus button while highlighting it in the leftmost column).

This made my computer stop occasionally crashing at boot.

I know that it was throwing fatal errors because, even though they weren't visible in the kernel logs, when I booted in safe mode, it threw about 50 errors in a second all relating to AirPort Wireless from ARPI.

I'm working on replacing the card - I hope this helps someone else.


Is there anyway to use an iphone/ipad as a mouse/keyboard locally (with a wire)?

There are apps such as Mobile Mouse Remote available which purport to offer various HID functions over USB. (This is not an endorsement of this specific product, just an example.) Connecting over WiFi seems to be more widely requested, but searching the web still turns up several non-wireless solutions.


When and how will it be moved to the App Store for being LIVE?

When the developer is confident the version is ready to go live, he/she just submits the TestFlight build (or a newer one with fixes) like a regular app update. Apple has to review it again (even if you use the same build as for TestFlight) and after approval it will go live.

  Apps, once uploaded, are automatically visible in the TestFlight app, when will this be removed: after 180 days, or 90 days, or when the app is live?

The standard testing period is 90 days, so after that, the app will disappear, but (IIRC) if that version of the app goes live, that ends the availability in TestFlight as well.

  When does the reviewing process start? The moment app is uploaded to TestFlight, or when it is promoted by someone for LIVE?

When the app is uploaded to TestFlight for an alpha test (by users which also have access to the iTunes Connect backend), no review takes place (except for some automated integrity checks). For a beta test via TestFlight, a short (manual) review is conducted by Apple, but nowhere near as rigorous as for an app going live. Again, the "going live"-review is a separate review.

  Who promotes the build for LIVE?

This is part of the process described under 1.

Is there any part of OSX that gets a significant speed boost from Intel AES instructions?

So... A bit of poking lead me to a simple conclusion: it's unlikely Apple will tell you where they use AES-NI instructions within Mac OS or the rest of their software, but they are definitely present and available.

Firstly, Intel talks a bit about AES-NI and where it is used. Some of the comments talk about its presence or lack there-of in the comments. Given that I have homebrew and wine installed on my Mac, I followed the interesting instructions here to test if the openssl dependency of wine is able to use AES:

$ openssl speed aes-256-c
...
The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
aes-256 cbc      69308.49k    74198.23k    75165.95k    74875.63k    76098.51k

$ openssl speed -evp aes-256-cbc
...
The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
aes-256-cbc     421057.71k   432531.16k   447445.08k   450021.03k   444866.56k

These numbers broadly agree with cyberciti's quote about 6x performance improvement using AES-NI.

Finally, we have some actual evidence in the SE community itself: https://stackoverflow.com/questions/12634305/.

Apparently, Apple used to provide an API for Mac OS which would not allow direct use of AES-NI instructions. The work-around used to be using Intel's compiler or building gcc from source. It appears that since 4.6.3, this is no longer the case, and developers can make use of AES-NI if they so choose. The performance improvements are then a function of the developers, not the OS.


How to rebuild iTunes Library with altered file locations without losing playcounts|ratings etc

There are a few AppleScripts from Doug Adams that might help you:

Fix Broken Tracks will merge the data of "dead tracks" (iTunes tracks designated with "!") with the real track that you have re-added to your iTunes Library.
iTunes Track CPR will check your library for "dead tracks" and re-add them while keeping all the previous metadata intact. In order for this script to work, the files need to be moved back to the iTunes Music Folder.
Music Folder Files Not Added displays files in iTunes Media folder which are not in the iTunes library.

It's important to read the manuals for these scripts before running them. Test a script only on a few tracks at first before running it on your entire library.

Theoretically the device list is as follows, running iOS 7 or later:

That said, this is the compatibility list for AirDrop which uses WiFi Direct as of iOS 7. Your mileage may vary with apps that are not utilizing AirDrop for the WiFi Direct functionality.


Is it possible to use a Mac Pro as four different PC's simultaneously using the multiple display output

Yes, this is possible to do. However, you will probably find that you'll need a lot more than 16GB RAM to make this practical.

16GB RAM is more than enough to simultaneously run macOS and a virtual machine. But in your case you're wanting to run macOS and four virtual machines. Remember that you will need to allocate both RAM and VRAM to your virtual machine from the 16GB of RAM you have on board.

My recommendation would be that you have a minimum of 32GB RAM installed so as to make the setup workable. Ideally, you'd install more than that. Officially Apple supports 64GB RAM in these machines, however users have found that they work just as reliably with 128GB RAM installed.

If I was going to do this, I'd actually have 64GB RAM installed and probably share one of the VMs with a Bootcamp installation. However, that's just a suggestion.

Either way, you only need to install Parallels once and then use it to create 4 virtual machines. If you do share one of these with a Bootcamp installation, then you'd obviously need a partition for that, but otherwise there's no need for multiple partitions.

In terms of the four displays, you would just move your VMs around to assign each of them to a different screen.

Finally, since you're using Parallels, you could even use it in 'Coherence' mode so you can have any app you're running on any of the screens without having to worry about which VM was running it.


Is putting the computer to sleep while it's in a hot car a bad idea?

Putting a computer in a hot car is a bad idea. The additional heat, generated by a sleeping MacBook is almost zero.

If you have to leave your computer in the car, and temperatures are (or will reach) near the storage limits (45°C/113°F) you should leave it in an thicker or insulated bag, that will protect the computer from the heat. Avoid direct sunlight at all cost.

Reduce file size of exported PDF from Notability app

Assuming your top priority is to minimize file size. You are going to have to sacrifice and switch over to an image format. Notability uses a vast amount of vectors in order to keep your handing writing sharp and readable at any size, so we will need to discard that information in favor of a simpler , less sharp jpeg file.

If you have photoshop, export all the files from Notability into an image format and bring them into your desktop to work on. Opening all the images inside Photoshop, use the “save for web” feature and select the absolute minimum of colors possible. I suggest 2 colors for the page (background & lines), and and 3-5 colors for pens (black, red, blue, green, is okay with dithering ).

This will allow you to create an image with minimal compression, at a sharper resolution.

If you have GIMP (free and open source <3): You can add an extension that gives you similar functionality to that of Photoshop’s “save for web” function. Here is a guide to how to install and use its different options on TemplateToaster.com.

These are both options for bringing 1920x1080 images down to about ~<80 KB each with readable text and minimal compression.

Edit:

I thought I would include an example that I create with my own notes, exported to Jpeg directly from Goodnotes 5 (this works regardless of program). All images are at the native resoultion of 1668x2154

Below are the results you can expect to see.

On the right, are the original, straight from Goodnotes exported jpegs. On the left, are the images compressed down with the "save for web" plugin on Gimp.

Below are the options that I used for most of the pages, with the exception of pages with images, where instead the "use web-optimized pallete" option was selected. Note how there are only 5 colors.(page, page line, 2 pen colors, white text)

Using this option will retain all text sharpness from the original exported text. Below is difference in quality, on the left is the compressed image, and the right uncompressed.

This should answer your question. As previously stated, you cannot expect to maintain the .pdf format and submit your work under such a tight data budget. The size of all the files combined together in the first image is in relative to a normal folder with all the images inside. When .zipped, you can expect an even larger file reduction (depending of course on the level of compression that you select with something like 7zip). As I predicted in my orignal response, the average file size among the 13 pages is 76.38 kb, just 3.62 kb under.


It is because Activity Monitor displays CPU usage as a percentage of a single core. So 100% means that one core is fully occupied.

The percentage can thus be higher than 100% when a program utilizes multiple cores.

The “yes” program is designed to use only one core, and use it fully. Therefore the behavior you’re seeing is entirely normal.

You may need to connect a USB keyboard if you need to make a change or enter 0 as part of a password, but once you're logged in you can copy / paste the 0 and also enable the keyboard viewer in system preferences.

That lets you get a 0 from the pointer / mouse / trackpad

Additionally, you could shift your keyboard mapping to Dvorak (left or right) and use a different physical key until you decide to get it repaired or see if you're ok using unicode hex input method.

With the unicode hex keyboard, you hold down option and type hex (0030 for zero) instead of ascii code.

How can I type unicode characters without using the mouse?

The main problem with unicode entry is the 0 is used quite a lot, so you'll probably want to set up a shortcut to convert another character to 0 or get a bluetooth keyboard.

To make a shortcut, go to system preferences/keyboard/text/replace with.  To create a custom layout where 0 is on a working key, try Ukelele.


How to disable the rubber banding/elastic scroll effect in OS X Mavericks?

There is no known solution at the moment – Apple seems to have deprecated the NSScrollViewRubberbanding command in 10.9.

You may find that it helps to do Settings > Accessibility > Mouse & Trackpad > Trackpad Options > Scrolling > Without Inertia. This won't actually disable the rubber band effect, but in my experience it makes it less annoying.

A window manager that re-sizes and re-arranges ALL the windows for a given application with one keyboard shortcut?

After testing Stay, I think it does what you want. Just launch your desired apps and store all open windows. You can then restore them on Stay's menu bar icon, with a shortcut key or have them restored automatically, when you launch each of the apps in question, or change displays.
I emailed Matt, Stay's dev and this is what he had to say about automatic restoration when launching apps and window title pattern matching:

Stay does indeed have an option to restore windows when launching apps. It’s the checkbox labelled "Restore Windows as applications are launched” in Stay’s preferences window.
Stay does its best to restore windows that it hasn’t seen before, but which are similar to windows that have been stored in Stay. When you store a window in Stay, it actually stores a set of attributes that it can use to identify that window, rather than a reference to the specific window that’s being stored. So if Stay sees another window that has the same identifying attributes, it will restore that window with the same size and position.
There are situations where this approach doesn’t actually work all that well in practice though, and as such, Stay has a feature designed to help with this called window title pattern matching. There’s documentation on this feature available here:
http://cordlessdog.com/stay/documentation/window-title-pattern-matching
The basic gist of it is that you can control how Stay identifies your windows by telling it how to identify windows by their titles. The simplest use case is to set a pattern of .* (period asterisk) on a stored window, which will make that stored window match all of an application’s windows.


Check your shell config files (i.e. .bashrc, .zshrc, etc.) Chances are, somewhere in there you're calling $(brew --prefix homebrew/php/php71), probably as part of a PATH setting. When you installed php via brew, it provided instructions for setting the path that would have included the above line.

I was seeing the exact same message, and changing this line solved the issue for me. You can change it to $(brew --prefix php@7.1) if you still need it.


I keep getting an error on RedLaser app for iPod Touch 4th generation. How to fix?

kCLErrorDomain is error reporting regarding the OS framework "Core Location." See this document for more info (written for OS X, which iOS is based upon).

So, for troubleshooting, I'd check your location services, maybe disable them/re-enable them and relaunch the app.

If that doesn't work, try re-downloading the app.

If the issue persists after a reinstallation of the app, the next step I would try would be to restore your device.


Anandtech has some nice charts detailing the wattage of the iPhone 4S running various apps, which could be a good starting point for you.

You may also want to check out existing kits/projects, such as MintyBoost - they seem to work reasonably well with iPhones. There's a specific MintyBoost page detailing Apple device charging that may also yield some useful info.


Permanently swapping option and command keys on a non-Apple keyboard

I assume you already know about the Keyboard Pref Pane. I had exactly the same problem with an Ergonomic and an Arc. The settings didn't stick with external keyboards.

Install KeyRemap4MacBook. It works for any Mac, btw. It remaps keys on all keyboards of a Mac - try to use Enter as Right-Cmd, e.g.

Set Cmd to Alt etc. for all keyboards in KeyRemap4MacBook (both right and left).
Switch the keys in the Keyboard Pref Pane for the internal keyboard.
Et voilà!

I figured out that weird hack some time ago. It turned out to be rock solid. Only thing to remember: hardware based utilities such as SteerMouse use the 'real' keys, so you need to switch around some things.


Problem moving application from DMG file

After you download the VLC.dmg, you double click on it to create a installer and it opens new window that looks like this.

Now just "drag" the VLC.app icon to the Application folder.

Alternatively, copy the VLC.app to the desktop and then move it to the Applications folder.

There are some reports regarding the Finder Error -36.

Try the "dot clean" as described here http://osxdaily.com/2015/02/21/fix-error-code-36-finder-mac-os-x/

and explained here: https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/dot_clean.1.html


iOS (iPhone) "Other" storage category is huge

As Steve Chambers commented - this was the ONLY thing that worked:

Backup phone on itunes to your local computer (not iCloud).
Wipe/Reset phone completely.  Delete all data and settings.
When it comes back up, plug into your computer again (or just leave it plugged into your commputer the entire time).
In iTunes, click restore from backup (the one you just made locally on your computer).

It will reload all your apps and settings to nearly the exact same (I had some things that randomly didn't restore properly and had to handle myself).  You'll also have to login again to some apps, but others you won't.
It also takes a long time, and is generally a pain.  But, given that this problem is all over the internet including on apple forums with no response or help from the company (typical), I will depend on this in the future too!


Network Share set permissions don't work

To create a properly working Projects share do the following:

On your external disk create a folder "Projects". Share this Projects with default permissions in Server.app > File Sharing. The default permissions are 755, the default owner is the user who created the folder and his primary group (e.g. adminuser:admin):

drwxr-xr-x+   6 adminuser  admin  -       204 Aug 23 10:54 Projects
 0: user:_spotlight inherited allow list,search,file_inherit,directory_inherit

In this folder create another folder with the name Projects. Change the permissions to 770 and the group to staff:

mkdir Projects
chown adminuser:staff Projects
chmod 770 Projects

The permissions now look like this:

drwxrwx---+   6 adminuser  staff  -       204 Aug 23 10:54 Projects
 0: user:_spotlight inherited allow list,search,file_inherit,directory_inherit

Then add an ACL for the group staff:

chmod +a "group:staff allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit" Projects

with the result:

drwxrwx---+ 2 adminuser  staff  -   68 Aug 23 11:09 Projects
 0: group:staff allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit
 1: user:_spotlight inherited allow list,search,file_inherit,directory_inherit

The complete path to the Projects folder (containing a test folder and a test.txt file - Data is the name of my volume on the external disk) is then:

/Volumes/Data/Projects/Projects:
total 0
drwxrwx---+ 4 adminuser  staff  - 136 Aug 23 11:24 . #this is /Volumes/Data/Projects/Projects
 0: group:staff allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit
 1: user:_spotlight inherited allow list,search,file_inherit,directory_inherit
drwxr-xr-x+ 6 adminuser  admin  - 204 Aug 23 11:09 .. #this is /Volumes/Data/Projects
 0: user:_spotlight inherited allow list,search,file_inherit,directory_inherit
drwxr-xr-x+ 2 adminuser  staff  -  68 Aug 23 11:24 test
 0: group:staff inherited allow list,add_file,search,add_subdirectory,delete_child,readattr,writeattr,readextattr,writeextattr,readsecurity,file_inherit,directory_inherit
 1: user:_spotlight inherited allow list,search,file_inherit,directory_inherit
-rw-r--r--+ 1 adminuser  staff  -   0 Aug 23 11:24 test.txt
 0: group:staff inherited allow read,write,execute,append,readattr,writeattr,readextattr,writeextattr,readsecurity
 1: user:_spotlight inherited allow read,execute

Now any subsequent file and folder of /Volumes/Data/Projects/Projects can be modified by any user in the group staff. You may tweak/tighten some of the permissions by not adding them (e.g. readextattr and writeextattr)


Photos for OS X: How to generate album automatically at import

I just wrote a small Apple Script to import folders and their subfolders as folders and albums into Photos. Have a look at it here: https://github.com/codez/ImportPhotoFolders. You probably need El Capitan to have it work correctly.


Apple Recycling Program
You can recycle it and receive a 10% discount on a new iPod. This is not only profitable for you and apple, but also a responsible way of deposing it.

Apple often achieves a 90 percent recovery rate by weight of the original product.


Force restart iPhone using a software (without iPhone's permission)

There's no way that I can think of to do it via software, but I do have a crude workaround idea.

You can let the battery die (you can accelerate this process by turning up the screen brightness), then plug in the phone. Crude, but the phone will turn itself off when the battery dies and turn itself on when you plug it in. It's effectively a restart.


Numbers error: not enough space in iCloud

This sort of weirdness sometimes comes about with versions and saved application state where the application doesn't want to let go of some data you added.

Do you have a Time Machine backup of the file in question? If not - be sure to copy out any data or log into the cloud version of numbers to be sure you have a cloud version you can live with.

Then clear the saved application state for Numbers by moving this file to your desktop or placing it in the trash can:

~/Library/Containers/com.apple.iWork.Numbers/Data/Library

If you don't have a good backup, I'd get one before deleting anything from your Saved State folders in ~/Library and if the Autosave Information and Saved Application State folders are empty you may need to delete the entire container.

If you're not sure about navigating to ~/Library which is hidden or restoring these files from a backup - Apple Support might be a good place to reach out to, but if you're familiar with moving things from the Library - I've seen clearing these help with oddball errors that you know aren't correct anymore.


Media keys not working for iTunes (pause/play, skip buttons)

This is an intentional change in macOS High Sierra. Rather than the media keys always controlling iTunes, they will now control whatever media is playing at a given moment.

9To5Mac has detailed a way to change this behavior with a third-party application, macOS High Sierra Media Key Enabler for iTunes and Spotify:

  Apple just released High Sierra and it brought good things and annoying things : they changed the behaviour of the media controller keys, they no longer control itunes, they control the video playback in safari. This pissed off a lot of people including me, so I just created a menu bar app to proxy media key events to iTunes/Spotify while Apple fixes this. It doesn't support touchbar yet, only physical buttons.


Time Machine says "There isn't enough space" and says I need 50 petabytes available to back up a one terabyte drive

The comments got me pointed in the right direction. In my case it seemed to be all the Python virtual environments I have. I excluded all that I could find, including ~/.pyenv/. Would be sad to lose those, but not the end of the world. I'll have everything else in source control.

How many copies of Mountain Lion does one App Store download get me?

You can install Mountain Lion on several Macs, provided that you use the same Apple ID for downloading it on them.

The Mountain Lion License Agreement explicitly says:

  Mac App Store License. If you obtained a license for the Apple Software from the Mac App Store, then subject to the terms and conditions of this License and as permitted by the Mac App Store Usage Rules set forth in the App Store Terms and Conditions (http://www.apple.com/legal/itunes/ww/) (“Usage Rules”), you are granted a limited, non-transferable, non-exclusive license:
  (i) to download, install, use, and run for personal, non-commercial use, one (1) copy of the Apple Software directly on each Apple-branded computer running OS X Lion or OS X Snow Leopard (“Mac computer”) that you own or control.

You can read the license by clicking the Terms and Conditions link at the bottom of the App Store window (left of the FAQ currently) and searching the license for the words "product usage" (presuming your store's terms are in english).


iTunes help switching songs from one user to another

Go to Home > Music and copy the "iTunes" folder to an external drive.

If you don't have an external drive big enough, you can move it to Macintosh HD > Users > (Your User Name) > Public > Dropbox. (You can copy it directly to your music file from another user, as those folders are only editable when you are in your account).

Login to your user, and move the "iTunes" folder from wherever it is to Home > Music. Open iTunes: your sister's library should be loaded.

PSS: I by no means am advocating the copy of copyrighted content with this post. I imply your music is legally downloaded, and you are moving the library with the intent of organizing it and not duplicating it in any way. Don't do illegal stuff!


In multi-monitor setup, how to control which workspace a newly launched app appears in?

Problem solved! Let's say that I was not that familiar with apps that were running but had no open windows. Along with that I'd never paid much mind to my Dock (I always hid it with the Genie Effect). And the fbara comment sealed my understanding.

note: When I was messing around with the options settings for apps on the Dock, a few times I was given the choice of selecting both a default monitor and workspace. I am not sure what I did though. I can't get that choice anymore.


For Filemaker Pro/Advanced 12 usually you'll have to contact customer service, provide proof of purchase and ask them to send you a new download link for the installer. (source) The good news is you get free support on installation as part of the license you pay for the software one time and you don't need to pay maintenance to get this help.

But here are links for
the Trial: Filemaker 12 Trial
Filemaker Pro 12.0.3.328 Filemaker Pro 12
Filemaker Pro Advanced 12.0.3.328 Filemaker Pro Advanced 12

For Filemaker Server 11/12 versions:

Server Versions 11/12 open the blue triangle and click the "FileMaker [11/12]  Updater"-link. Scroll down the opening page and a full installer for "FileMaker [11/12]" will be available for download.


see
http://endlessgeek.com/2014/03/batch-convert-iphoto-videos-mp4/

It uses handbrake.
Best way is to experiment manually with a handful of videos and watch out for compression artefacts (the color-bleed-out blocks on faces and other smooth color transitions). When you are satisfied, create a profile with the settings, name it e.g. MyProfile. You can use these settings by invoking the cli version of handbrake inside the batch script with --preset="MyProfile"

Where or how do you store the originals?
Don't throw away information lightheartedly. This is what you do when compressing.

I copy the original folders of my canon camera manually to my external drive, additionally to importing stuff to iphoto.
So iphotos videos are rather.... dependable.

I will modify the script to directly access the originals inside the photo library. This a really bad thing to do, normally.
If you want try to contact me 1'2016. appstackex-imov4m.hofma at the service 0ox with domain .com ;)

If you try this, too, please backup before tampering with the package!

Read http://osxdaily.com/2015/04/22/show-original-file-from-photos-app-mac-finder-osx/ to see the part/video where they open the package in finder.

In finder, you can locate your library, for me and just e.g.it is:
~/Pictures/Fotos-Mediathek.photoslibrary/Masters/
(photoslibrary is the new one since migration of the iphoto database to photos database. Just look in finder, right-click "open library content" or whatever the menue entry reads in english, might be "packet content" (it is "Paketinhalt anzeigen" for me) then open the subfolder "masters", and drag the masters-folder to terminal, then you have text on the command line representing the correct location...

When you do a change directory to the path of masters, you can thereafter find all originals, e.g. by:

find . -type f \( -iname "*.mov" -o -name "*.mp4" -o -name "*.jpg" \)

This is nice for me, because I have a bunch of empty folders in this directory structure created by iphoto / photos. Find does show only results with a nice relative path.


cannot see photo clearly from ipod touch library locally

In Settings, select iCloud, then Photos, and then turn on Download and Keep Originals. This will move all of your iCloud photos in full resolution to your iPod.


Does Spotlight index content that resides only on iCloud Drive after local storage is purged?

Yes Spotlight is indexing iCloud Drive. It could take a while before your iCloud Drive is indexed.

Spotlight even shows if the file you are looking for is located in iCloud Drive.

To test if the metadata is still working after the file is purged I did:

Added test333 in the file comments
Moved it to iCloud Drive
Occupied a lot of space with an empty disk image
The system purged the file
Searched for the comment


How can I mark a podcast as "Listened to" on my iPhone?

Well, you could start playing it and quickly fast-forward to the end.  Or, you could use a different app for podcasts, such as Instacast or Pocket Casts.


brew uses /usr/bin/autom4te in stead of /usr/local/bin/autom4te

I went ahead and renamed the files autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate and ifnames in /usr/bin to force my machine to use the ones made available in /usr/local/bin after a brew link --force autoconf.

Brewing worked without an issue.

I don't know where the files in /usr/bin/ came from or if I borked things up bad by doing this. I'm keeping the renamed files in place, just in case I ever remember what I did today when things start to stink.

(see https://github.com/mxcl/homebrew/issues/20586 for more troubleshooting)


Create a new iOS backup without deleting the previous one

You're close: Preferences > Devices

iCloud Photo Library not fully syncing on iOS

Turn your iPhone off and the back on. If that doesn't help, disable iCloud Photo Library and then turn it back on. If that doesn't help, logout entirely out of iCloud and then re-enable it.


I'm saving debug logs for iTerm2 but why can't I find them?

Perhaps that message is from a time where the temporary directory was indeed /tmp many macOS versions ago. Nowadays macOS manages a private temporary directory per GUI user which is provided as the environment variable $TMPDIR somewhere in /var/folders — try open $TMPDIR/debuglog.txt.


GPS and GLONASS are almost the same things, one operated from the USA and the other from Russia, respectively. The differences are too technical for this question and I won’t get into them.

Also, if your new iPhone 4S ships with iOS 6, you won’t be able to downgrade to iOS 5.

And yes, you can see your location in offline maps.


How can I get rid of excel files that I can't delete

Force quitting finder "fixes" this but is a work-around. If no one has a better fix, I'm going to have to mark this as the answer.

Press option down while right-clicking the finder in the dock, then click "Relaunch". It relaunched the desktop and the random excel file went away.


Why does the 2021 Mac have a lower Ghz processor than the 2017?

I take it you are concerned that in some way a lower GHz indicates less powerful CPU.  But let's look in a little detail at the GHz values and the different 'generation' of CPU.  I will just consider the lowest specs, that is

2017: 3.4GHz quad‑core Intel 7th-generation Core i5 (Turbo Boost up to 3.8GHz)
2021: 3.1GHz 6‑core Intel 10th-generation Core i5, Turbo Boost up to 4.5GHz.

Firstly there is 3-generations of Intel's Core processors between the two.  Without attempting to be specific, we can assume some improvement in efficiency for the same speed processor.
For mostly single-threaded applications (e.g. browser, word processor) the Turbo-boost value is important.  Here we see in increase in processor speed from 3.8 to 4.5 GHz.
The processor load will increase as more applications (and background tasks) are running and as the type of application moves to those being multi-threaded which can use many processor cores.  Such applications include photo and video processing.
At maximum load, all 4 cores (2017) or all 6 cores (2021) will become fully utilised.  When fully utilised the processor speed may reduce to 3.4 GHz (2017) and 3.1 GHz (2021). If we multiply cores by GHz (3.4x4 and 3.1x6) we can see that that the newer processor is capable of considerably more work - the lower speed is outweighed by the increase in core count.
In practice both CPUs will probably run a bit faster than 3.4 and 3.1 GHz when under full load unless the ambient temperature is high.
In summary we have three things making the newer CPU outperform the older one:

Newer generation of processor;
Single threaded speed (maximum Turbo Boost);
Core count (even though base speed is lower).

You also might like to know that, as a power saving measure, both processors will reduce their speed when under a light load.
And, of course, there are considerably higher performance CPUs available for both 2017 and 2021 iMacs if that is desired.
Finally you might like to browse Geekbench results for the two processors:

2017
2021

These show a modest improvement in single threaded performance and a greater improvement in multi threaded.


Reclaim lost space from Bootcamp Partition

I suggest creating the USB flash drive installer, because it takes you 30+ minutes to boot to Internet Recovery. If you want to use Internet Recovery then use the alternate instructions given below.

Backup Macintosh HD with Time Machine to an external drive.
Download High Sierra from the Apps Store. If the download software starts to execute, cancel the execution.
Transfer High Sierra to a USB flash drive. See How to create a bootable installer for macOS.
Restart the Mac and immediately hold down the option key. When the Startup Manager icons appear, choose the installer.
From the menu bar, choose the Terminal application.
Enter the commands given below to create the new Logical Volume Group (LVG)

diskutil  unmount  "Macintosh HD"
diskutil  cs  createLVG  "Macintosh HD"  disk0  disk1

Use the command below to determine the UUID of the new LVG.

diskutil  cs  list

For example, you would look for a line similar to what is shown below.

+-- Logical Volume Group A8CEEF75-6839-4806-B799-97CF0CAABB7C

Enter the command given below to create a new Logical Volume (LV).

diskutil  coreStorage  createVolume  <UUID from previous step>  jhfs+ "Macintosh HD"  100%

For example, drawing on the example in the previous step, you should enter a command similar to what is given below.

diskutil  coreStorage  createVolume  A8CEEF75-6839-4806-B799-97CF0CAABB7C  jhfs+  "Macintosh HD"  100%

  Note: Replace A8CEEF75-6839-4806-B799-97CF0CAABB7C with the UUID you determined in the previous step.

Quit the Terminal and use Time Machine to restore your files.

  Note: The OP has reported a complete verbatim restore works better than selectively restoring files.

Install High Sierra. Be sure to select that you what to keep your files.

Alternate Instructions

  Note: Requires macOS Sierra 10.12.4 or later,.

There instruction require booting to Internet Recovery.

Backup Macintosh HD with Time Machine to an external drive.

  Note: Replace A8CEEF75-6839-4806-B799-97CF0CAABB7C with the UUID you determined in the previous step.

Quit the Terminal and use Time Machine to restore your files.

  Note: The OP has reported a complete verbatim restore works better than selectively restoring files.

Install High Sierra. Be sure to select that you what to keep your files.


bash-command not found; for every command == fear i could screwed up the path

Commands you run in Terminal need to either in one of the directories included in $PATH or you need to call them with ./command if you are in the directory the command is stored in.


I believe I have figured it out. I relocated my iPhoto library but had never opened it afterwards in iPhoto. I believe that iTunes has a memory leak in handling when it tries to access the library that no longer exists. Once I opened iPhoto and selected the new library location the memory leak in iTunes stopped.


I hope you still ready this - it has been a while.

I spent my whole Chrismas and new year holidays fighting with similar situation.

I found out the main issues are:

MBR vs GPT (please google)
disk letter ID (e.g. C: - D: ....)
use some third party software to deal with partition and disk address
use some third party software to Clone the disk.

Good luck !


Force contacts to sync with iCloud right now

I assume it's a little late for your phone call, but for anyone else with this problem you can force both the OS X and iOS Contacts apps to sync with different methods.

OS X
Close (and reopen?) the Contacts app.

iOS (8)
Touch Groups on the top left, then drag down until the spinner at the top fills up.


I currently have OS 10.6 want to upgrade OS

It looks like you can use CS4 with Mavericks according to Adobe's site.

  Is Adobe aware of any major issues, bugs, or odd user experiences when
  using CS5, CS4, or CS3 products with Mac OS X Mavericks (10.9)?

  Yes, Adobe Drive could cause the opening or saving of files to take
  longer. See Files open, save slowly for more information.


How can I silence the screenshot camera sound?

To my knowledge, there technically is not a way to specifically and only disable the camera shutter sound for screenshots, but there are still solutions to stop it from making the sound:

One thing you can do is flip the mute toggle switch on the side of your device to be muted (silent/vibrate). You will see a Ringer Silent icon on the screen and may feel a vibration on an iPhone. After that, there will be no noise from the screenshot (among other things).

On an iPhone, if you don't wan't to get the vibration when turning the phone to silent, or if you want to leave it on silent without getting vibrations, you can go to Settings > Sound and toggle "Vibrate on Silent" off. Then it won't vibrate or make any noise. However, you also won't hear any notification sounds or vibrations at all, so you run the risk of missing some alerts. So in this case what you may want to do is flip the mute toggle to silent right before taking a screenshot (and it won't make any noise from vibration), and then after the screenshot flip it back to normal.

Another alternative, if you don't mind the camera shutter sound but just want it quieter, is that in Settings > Sounds you can slide Ringer and Alerts to minimum. It'll still make sounds, just quietly. But again you run the risk of missing your phone ringing in some situations as it'll be quiet.

Edit: I noticed that on iOS 10.3, when you toggle the mute switch while the camera is open, it does not make any vibration. So you could just toggle it to mute before you take the picture, and then toggle back to normal when you're done.


You could try Settings -> General -> Reset -> Reset Network Settings.

From the docs:

  This will reset all network settings including:

  previously connected Wi-Fi networks and passwords
  recently used Bluetooth accessories
  VPN and APN settings

More information about troubleshooting WiFi networks is available here:

Can I use my iPhone's 18W adapter on my MacBook Pro? And vice versa?

Yes, it is safe to connect the 18W USB-C power adapter to a MacBook Pro. However, I wouldn't expect it to actually be useful for charging the laptop. The charger supports 5V (max 15W) and 9V (max 18W), but with the MacBook Pro you really want a 15V or 20V charger to be able to get some energy transferred in a timely manner.

And yes, it is also safe to use the MacBook Pro's USB-C charger with the iPhone 11 Pro using the correct cable. It should be able to charge your phone just fine.


Hard Drive doesn't show in Recovery Mode

'Going back' & 'update' are mutually exclusive terms.
You will need to re-format the drive to HFS+ first from Disk Utility. El Capitan cannot read or understand the APFS disk format that Catalina uses.
Your edit suggests you are still in Catalina & that your disk is currently APFS.
You will need to start from your external El Capitan boot medium [or from Internet Recovery] in order to be able to format your boot drive [you cannot format the drive you are booted from, for obvious reasons.]
Select the Physical disk in the left column [Apple SSD] & select Erase. Set to GUID/HFS Extended, Journalled.


connect to relative remote iMac via finder hanging

Since Apple removed 'Back to my Mac' from the system, it's been harder to get structures like this to work for the average home user.

The primary issue is that you need to use port forwarding on the remote router - not insurmountable, unless it's your 80-year-old technically-challenged granny who needs to set this up, 2,000 miles away. [Been there, done that].
Even if you are able to set up port forwarding, because you are setting up  commonly-used ports & protocols, you will then find you get a constant stream of random remote requests coming through it, from chancers trying to find a weak spot. You can't lock it down to requests from a specific IP address, because consumer IP addresses can change at any time.

So… forget that idea.

Instead, look at something whereby each user connects outbound to a remote server, which can then allow them to perform a secure handshake, then hook up directly to each other, without your firewall getting in the way.
It is far easier to see out through a firewall than try to punch a hole in. It requires no technical expertise from the user. Your browser does it every day.

There are many solutions to this problem, & the first one that always springs to mind is TeamViewer. I've used it, many years ago, it worked just fine. However, if they ever think you're using this for corporate purposes, they lock you out, rather unforgivingly. I eventually gave up trying to persuade them that one set of parents lived 200 miles in one direction & the other set 2,000 miles in the opposite direction, in a different country.

So, you could try TeamViewer, or one of the many alternatives that have sprung up over the past 10 years.

I normally don't like posting links to online comparisons as they often seem to be only trying to sell you their own solution rather than being fair & even-handed, but this one does appear to be un-biased. Ionos - Alternatives to TeamViewer
Most of those have free versions for home users, so pick one by feature-set; which looks the most useful to you. I'd probably go for AnyDesk these days, partly because it's supported on most platforms but also because it's made by a splinter from TeamViewer & aims to be faster, but I've not yet tried it so I can't honestly say which would be best these days.


Try resetting your phone I was having the same problem, make sure to close ever app before turning your phone off. It's working for me at the moment but I've been having this problem since iOS 6 and also in iOS 7 now, so who knows how long it'll work.


How do i restore data from an iCloud backup to my PC after my hard drive crashed?

iLoot (free) can help you for iCloud restoring! no device needed!
just tried it, worked fine and restored everything.


You can use -E flag, from man:

  -E      Interpret regular expressions followed by -regex and -iregex primaries as extended (modern) regular expressions rather than basic regular expressions (BRE's).  The
               re_format(7) manual page fully describes both formats.

In this case your find command will look like:

find -E ~/Library -regex '.*(citrix|cisco).*' -print 2>/dev/null


How do I move pictures and videos from one iPad to another?

This depends, do you have iCloud? as you can sync through iCloud.

You can also configure all the settings in iTunes. So you can import all the images into iTunes, once they are there you can connect the other iPad and sync them.

If you do not want to keep the iPad 1, you can just connect it to iTunes, sync it and then connect the iPad 2 and restore it from the back up of the 1st iPad.
