I think your conclusion is wrong - even if it looks that way superficially, the snapshot is actually not changed.

The thing that tricks you here is your one of the folders in your path is actually a link. If you're running on pre-Catalina macOS version, you probably have /Users as a symbolic link. If you're running on Catalina, /Users is a firmlink.

This means that when you run ls /private/tmp/snap/Users/dmd/foo to check for the file, you're actually not looking at a file inside the snapshot, but rather the system will traverse the link inside the snapshot and onto your ordinary volume for the actual file.

If you're on Catalina and want to redo your commands without the link interferring with you, you will need to instead use the following command to check for existence of the file inside the snapshot:

ls /private/tmp/snap/System/Volumes/Data/Users/dmd/foo

macOS Catalina - Keyboard and Trackpad not working

It seems that your issue is not with the MacOS itself but rather due to the hardware controller inside your computer. In such cases, you should reset the System Management Controller (SMC) by following the steps below:

Turn off your computer
Press and hold Shift + Control + Option (Alt) + Power Button for 10 seconds
Release the keys and let the MacOS boot up


Why won't Special Characters display certain characters?

First, you may need to enable these groups by clicking the button in the upper left and choosing "Customize List…":

Then find the desired list and check the checkbox:

If you have done this and you see boxes instead of characters, it just means you don't have a font that supports those characters. If you download and install an appropriate font you should start seeing the characters.


I think it's possibly 'Displays have separate Spaces' in System Prefs > Mission Control.
I've had that switched off since it was added to prefs, & only have a menu bar on my main monitor.

I don't want to switch it back to test, it messes things up ;-)


How can I export my Comcast address book to my iPad?

Follow this guide to export your contacts from Comcast in the vCard format (VCF): http://www.watchingthenet.com/export-address-book-contacts-from-comcast-webmail.html

Then, email the vCard file to yourself. Open that email on your iPad and download the attachment. Now you will have your Comcast contacts on your iPad.


Can't find SUMIF in my Numbers functions. Could someone tell me where to find it?

To get to SUMIF you need to call up the function browser. To do that go to the cell where you want the result to appear and hit the '=' key and it will appear as a popup


The asr target option --settype "Apple_HFS" modifies the GPT partition type but not the file system. So the partition "content" is 48465300-0000-11AA-AA11-00306543ECAC (which is an indicator for a normal HFS+ partition) but the file system on disk6s2 still is NTFS/ExFAT/FAT32.

If the disk is empty, simply erase it with Disk Utility to whatever you need.

Changing the partition "content" with gpt or another similar tool doesn't alter the file system. Your volume may not mount if content and file system don't match!

BTW asr is not the proper tool to format volumes, create file systems or to change the partition type. This is rather done with newfs_XY, diskutil and gpt.

To determine or examine the file system you would have to open the volume as raw data and check for specific headers or fs structures.


OS X 10.7 Lion: Reset master password to FileVault 2

It's surprisingly simple.

Delete /Library/Keychains/FileVaultMaster.keychain
Delete /Library/Keychains/FileVaultMaster.cer

When you return to set a new password your old one will have been cleared.

Based on step 4 in How to create and deploy a recovery key for FileVault 2.


Yosemite: Cannot Music / iTunes - black screen and won't accept password

I'm afraid I've got the same problem.

I restarted the Imac yesterday. The close down took more than 3 minutes. This happend before. I forced the closing down by pressing the power button. After normal start up I could not start iTunes anymore. All other apps function properly. The desktop shifts left and a black screen appears. I can operate the dock and other programms though. I can only get out by forced stop of iTunes.
If I attach my iPhone and start iTunes, a screen prompting me to update it appears (on top of the desktop). I cannot operate it however, as it it is complete dead!

I also tried other option as close full screen, launchpad, ect.

Strange thing is that this occurred about the samen time as my wife synced an iPad which belonged to me before. She was asked to enter ID's of which one was my ID related to buys I suppose.
I checked my iCloud account. It is still active.

PS!!
I just cracked it! I moved (not copied!) the itunes library to a temp folder.
I restarted iTunes and it immediately came up with the familiar screen. Probably a new library was created. I then imported the info from the temp folder (trough the menu). The new library was updated. I could notice by syncing the iPhone. Also my music is back and available.


Can You Stop the Migration Assistant Midway Through?

Pressing Command + Q on both machines will exit the migration assistant.

I have a feeling that it copies all files to temporary location before installing them/creating user accounts. So you should be fine. Depending on how far in you might have problems.


Restored a file from Time Machine when Backup Disk not available

I believe it is because Time Machine (in 10.7 and 10.7) keep local backups to augment the external drives.

He is an Apple support article.

"Local snapshots compliment regular Time Machine backups (that are stored on your external disk or Time Capsule), giving you a "safety net" for times when you might be away from your external backup disk or Time Capsule and accidentally delete a file."


Alternative Method to Acquire El Capitan Upgrade

Don't is my recommendation. This is how malware gets introduced into Apple software - like the Xcode ghost where developers were not downloading from Apple and not checking the validity of the software they installed.

If you call AppleCare, they might sell you physical media or even comp the shipping charge if they feel yours is a legitimate need to avoid the download. You could also find someone you trusted to have them make you an installer and ship it to you.

I have known people that went to an Apple store and asked if they could sign in to the App Store on a Mac there and download the installer to a USB drive. Since the store probably runs a caching server, even downloading 10 GB of data would proceed in a matter of minutes.

What is the best way to generate a Yosemite or Mavericks Install USB flash drive?


How can I replace the original AppleIntelCPUPowermanagementClient.kext in OS X Lion?

The first thing you should try is installing the OS X Lion Update 10.7.3 (Client Combo). If that doesn't replace those files then you'd have to reinstall OS X over your existing install.

However, since you're already messing around inside the System folder, you may be interested in trying to copy those files from your Recovery HD partition. To do this, you need to mount the Recovery HD, then mount the Base System image on it.

Mount the Recovery HD in Terminal with this command:

diskutil mount "Recovery HD"

Mount the BaseSystem.dmg with this command:

hdiutil mount /Volumes/Recovery\ HD/com.apple.recovery.boot/BaseSystem.dmg

You can then try copying the files from the "Mac OS X Base System" disk image to your system folder. After copying, make sure the owner/permissions are correct (running Disk Utility's repair permissions would be a good idea).

I haven't tested this, but the file sizes of each is the same in both the Base System image and the full install of OS X, so it seems likely they're the same.


What Icon Display Resolutions and Pixel Densities Should I Use?

Use the resolution given in the name of the image. For @2x images, double the resolution in both directions. PPI does not matter—Apple uses 72 PPI. Do not use any transparency or interlacing.

For example: icon_512x512@2x.png is a 1024x1024 image.


How can I access the same account (and files) from either of two Macs?

Yes, the same is possible with Macs.

Usually you would create such a setup using macOS Server, which includes these features. macOS Server costs $19.99 on the App Store.

This will require you to have either a seperate dedicated server, or assign one of your existing computers to also be a server. The server must be running in order for you to be able to login with such a "shared" account on other computers.

You can also setup this manually, similar to a Linux setup:

This would require you to have some sort of directory setup in order to share the account itself across computers (i.e. typically OpenDirectory or Active Directory - that is variations of LDAP). In your very limited setup you could also manually setup your account on each Mac.

In addition to this you would need a NFS file server to store the actual contents of your home directory (i.e. all your files) on.

The performance of either solution in terms of read/write speed is comparable to the Linux solution, as it is really the exact same type of setup.


Constant beachball and freezes without high CPU usage, "nspace-handler-update: did not find token" message

Finally this gave the clue.

It was caused by Sophos Antivirus.  Uninstalling it fixed the problem.


Mail gone after clean install of El Capitan

I decided to restore my mails by hand. That took me a few hours, but now I am back to normal.

Here is what I did:

Import every local mailbox from the backup
Clean up the mail boxes (Cryptic folders were generated inside every mailbox)
Add the POP accounts.
Write mails from there to get a dedicated "send" folder for each account.
Put the imported mails in the appropriate location (inbox, drafts, sent)
Add the IMAP accounts.

What I realized after going through all those steps, is that the accounts inside of ~/Library/Mail/V3 are not named by there account names anymore. Instead the consist of a cryptic combination of numbers and characters. Maybe that was the cause why Mail did not import anything.

My guess is, that accounts are now referenced by a number/character-code out of security reasons. However, that leaves me wondering how to do a proper backup of mail for a clean install.


AppleScript / Javascript : remove columns in Safari

.removeAttribute(attrName) takes an attribute name, not value.
The attribute name is 'class', the value is 'sortable cardTypeDisplayName'.
However, that's not going to fix the problem either. Removing the attribute from the element doesn't remove the element entirely, it just removes the attribute, such that your example becomes Visa	 — i.e. the column still exists.

To remove all elements with a class attribute exactly matching 'sortable cardTypeDisplayName', you can use the following JavaScript.

document.querySelectorAll("[class=\"sortable cardTypeDisplayName\"]")
        .forEach(el => el.remove());

This problem is with your JavaScript, not AppleScript. Debug your JavaScript in the web browser developer tools first before moving to AppleScript.

To run this JavaScript with AppleScript, keep in mind the quotes that need escaping. Look at the syntax highlighting to see how the quotes in the JavaScript are being parsed as quotes for AppleScript to use on the string itself, rather than given to JavaScript. These quotes need escaping.

tell application "Safari" to ¬
  do JavaScript "document.querySelectorAll(\"[class=\\\"module question-stats\\\"]\").forEach(el => el.remove());" ¬
    in current tab of window 1

tell application "Safari" to ¬
  do JavaScript "document.querySelectorAll('[class=\"module question-stats\"]').forEach(el => el.remove());" ¬
    in current tab of window 1


How to bring focus to Show Fonts dialog (eg. in TextEdit) on a MacBook Pro keyboard?

After you open the Show Fonts window, you can press Ctrl+F6 to bring focus to the floating Fonts window. To return focus to the window you were in, you can press Ctrl+F4.

On a laptop, you'll also need to hold Fn when you press the above keyboard shortcuts unless you go to System Preferences > Keyboard and check "Use all F1, F2, etc. keys as standard function keys".

After you move focus to the Fonts window, you can press Tab and Shift+Tab to cycle focus through the different columns and the search field.


How much data can an app steal from my MacBook if I allow its system-wide execution?

This is not an exact answer to what you are looking for, but it is ONE way that you can keep your system safe.

Basically it is an outbound firewall that I have been using for years (I hold no interest in the company, just a happy customer) and it is called Little Snitch.

Basically, once installed, it monitors ALL network traffic and throws up a warning when it sees any. Training it to respect your preferences can be a bit tedious as it presents a dialog on absolutely everything on the Mac that wants to talk to something on the internet.

But with a little perseverance and some intimate knowledge of what certain processes are you can essentially block anything that wants to initiate anything in the way of an outbound network connection. It's not free but worth every penny.

There are likely other things out there that might do the trick. I think there is a Docker project for the Mac, but I have no expertise or knowledge of it other than it (may) exist. But Little Snitch is a worthy addition to every Mac user's Mac who enjoys fiddling around with more than email, a web browser and a few apps & games.

macOS Sierra caps lock disabled in non-latin languages

I have verified that if you use Ukelele to create a duplicate Hebrew keyboard layout (with a different name of course), Caps Lock will function on it like it does in El Capitan.


How to jailbreak on an iOS 10.2 on an iPhone 5s

As per my little knowledge regarding iOS, I found Yalu jailbreak is updated and release to jailbreak iPhone 5S.

  Step 1: First up, connect your compatible iPhone or iPad device to a
  Windows or Mac computer using a Lightning/USB cable.

  Step 2: As a precaution, make a complete backup of the data on the
  device using iTunes so that you can return to it in case anything goes
  wrong with the jailbreak process you are about to perform.

  Step 3: Launch Cydia Impactor on your computer.

  Step 4: Drag and drop the yalu102 IPA file you downloaded earlier on
  Cydia Impactor.

  Step 6: Wait for Cydia Impactor to install the yalu102 jailbreak app
  onto your iPhone or iPad.

  Step 7: Once installed, disconnect your device from computer and head
  to Settings >  General > Profile(s) & Device Management or General >
  Device Management and hit Trust and then Trust again on the
  certificate you used to install this jailbreak app.

For detailed tutorial, please check Redmond Pie or Team Cydia.


Time on macbook (Mojave) is incorrect with auto-time on (Is apple time server wrong?)

You can trigger the sync manually by running

How to disable AddressBookSourceSync in El Capitan

Not sure if this is really a good idea, but you can run this (as yourself, not root) in Terminal:

launchctl unload -w /System/Library/LaunchAgents/com.apple.AddressBook.SourceSync.plist

FWIW, I had the same problem and even after following the instructions in Tetsujin's link, turning off all Contacts accounts in System Preferences, logging out of iCloud, blowing away the AddressBookSourceSync directories in ~/Library/Caches and ~/Library/Application Support, and of course many reboots, I could not get AddressBookSourceSync to stop blocking sleep. This command “fixed” it. AddressBookSourceSync no longer runs and pmset -g reports nothing preventing sleep.

You can undo the effect with this command:

launchctl load -w /System/Library/LaunchAgents/com.apple.AddressBook.SourceSync.plist


How to configure where Lion fullscreen apps open

Look at System Preferences > Mission Control and see if 'Automatically rearrange spaces based on most recent use' is checked.

When checked, fullscreen windows open to the immediate right.

When unchecked, fullscreen windows open at the far right, after all other desktop spaces.

You can also rearrange desktop spaces by dragging them to the order you prefer in Mission Control.

(I'm running 10.7.3)


Try restarting your iPhone by holding the lock button and home button together until you see an Apple logo appear. If that doesn't work, I'd attribute that issue to a bug. The iPhone 6S is kind of buggy, mine won't play system or Taptic Feedback sounds sometimes. So we may just have to wait for software updates.


Why are some shortcuts modified with the Shift key while others are modified with the Option key?

Well, coming from a Windows background myself, I can state the following:

The Cmd key is usually like Ctrl on Windows (e.g., Ctrl+c == Cmd+c).
As with Windows, the Shift key is a common modifier to the Cmd key.
I believe that Macs traditionally had an Option key, which also came to be known as the Alt key (perhaps to help those accustomed to Windows).
Aside from that, both Ctrl and Option are treated like modifiers on the Cmd key.

Between different Mac applications, there is sorta an effort to have some consistency in what certain key combinations do. For example, Ctrl+Cmd+f is usually a full-screen toggle.

However, the consistency of such keyboard shortcuts can vary per the software publisher.

Now, as a person that is familiar with Windows, you'll notice that Alt doesn't activate a menu mode, such as being able to drill down to a specific menu item.

However,you can create a keyboard shortcut via System Preferences >> Keyboard >> Shortcuts >> App Shortcuts. Just type the shortcut name as it appears in the application's menu.


Is it possible to install Tor Browser on iPad?

If I am understanding you correctly you are trying to download the macOS version of TorBrowser on your iPad?

If that is correct, that will never work. The only place to download/install/buy applications for iOS devices is the App Store which is itself an app on your iPad.

If you want a good Tor Browser on your iPad I use one called "Onion Browser" that seems to do the trick. Just search the App Store for that name and it will pop up. There are likely others that will doo a decent job too, but that is a good place to start.


https://support.apple.com/kb/PH18757?locale=en_US

This link explains it. Its a new(ish) feature. You can zoom to mission control (f3) or for those with a MacBook, and you have new haptic track pad, you just three finger scroll up and if you move your cursor to the top right corner of your screen you will see a plus sign appear. Click on this to add a new desktop.

You can get rid of it by Going back to mission control again (f3), where you will see all open apps, and you can just close it (them) by hovering your cursor over it and an x will appear on top left corner it, or anything else, out from there. If you're in mission control it's easy to inadvertently create additional desktops if you thro your cursor up out of your way.., I've done it a few times.

It can be super useful when you want one open for work and one for play, but that I guess is not the point. Easy to get and get rid of though. Many good publications on how to make most of the feature if you ever want to.


There is Super Remove Dead Tracks, but that's probably not exactly what you want. Then there is iTunes Track CPR which seems to be closer but still not what you need. Maybe contacting one of the authors (or extending the AppleScript code yourself) might help.


Send push notification to iOS without a native app?

No. Unfortunately, you must have an app to send notifications.


Prevent Sierra from opening a Window for a new Volume

I haven't relied on this in the Sierra times, but you might get lucky with the venerable unix fstab functionality and removing your default commands that weren't effective:

diskutil info /Volumes/Web\ Connection

Get the UUID and add a line to your /etc/fstab file

UUID=12345678-1ABC-1CDE-1FGH-123456789012 none hfs rw,noauto

There are some more details at https://discussions.apple.com/docs/DOC-7942 covering a nice use of the vifs command which safely edits the /etc/fstab file in place. Some good discussion on the mounting mechanics are at: How does Mac OS X decide which volumes to mount? One of my disks doesn't mount at boot


Is it possible to use Thunderbolt networking and regular ethernet networking simultaneously?

Yes, that is definitely possible - indeed this is what happens if you hook them up like this.

Thunderbolt 3 enables transfer rates up to a theoretically high of 40 Gbps.

The relative speed depends on the type of Ethernet connection you're comparing it with. If you're using 10-gigabit ethernet - then you're probably not going to see any practical benefit from the Thunderbolt 3 connection (if you're not transferring stuff from disk, you might get huge benefits though). If you're using gigabit or slow ethernet, you're going to see a massive improvement in transfer speeds.


The smoke coming out of your Macbook would lead anyone to conclude that the problem system had either an:

Overheating battery (common on some model MBP's)
Overheating CPU (not at all common unless there is a blockage or other external heat.)

As others have suggested, it is definitely time for you to triage and rescue whatever remains on the HDD and take it to the Apple Store for a further diagnosis. Here are some things you can do in the meantime

Verify if the battery is the problem. Take a careful look at the chassis of the aluminum unibody. Does it seem swollen in some areas? If you use one finger to press on an edge of the MBP, does it rock? Swollen batteries are a common indicator of battery malfunction.
If the battery is removable from the bottom of the MBP, go ahead and remove it. Attach the AC adapter and power on your MBP without the battery installed. This should mitigate your device from turning off because of the heat from a malfunctioning battery. Other things you can do is place your device on a cool, dry kitchen counter while running it without the battery. This will further allow you to use the computer without risk of running into the CPU thermal throttling timer (simple function: too hot -> turn off).
Lastly, if the above tip worked, immediately move your HDD contents to a backup location.

Please report back on your findings and mark answered if this helps.


How critical are macOS Mojave compatibility requirements?

For an unpatched installer the requirements set forth are final. Early 2011 MacBook Pros are not supported and the installer will not work.

That does not mean that it does not work at all.

Using dosdude1's Mojave patcher you can install it easily, but with quite a number of some caveats:

  Current Issues

  Graphics anomalies: Currently, pre-metal video cards used in Mojave will produce a weird darkish grey Menu Bar and Finder sidebar when using the light theme. In the dark theme, these anomalies are not present, while other, less obvious anomalies are present (window corners may not render properly, bottom part of dock menus may have artifacts). A workaround for graphics anomalies in light mode is to enable Reduce Transparency in System Preferences > Accessibility > Display (this might create additional side effects beside the obvious loss of transpareny as some systems with pre-metal AMD graphics render the dock in dark gray).
  AMD Radeon HD 5xxx/6xxx series GPU acceleration: Currently, it is not possible to get full graphics acceleration when running Mojave on a system with a Radeon HD 5xxx or 6xxx series GPU. Mojave will be almost UNUSABLE without graphics acceleration. This includes the 15" and 17" MacBook Pro systems (MacBookPro8,2 and 8,3). If you want to enable GPU acceleration on these machines, you'll need to disable the AMD GPU (This will work on MacBook Pro 8,2 and 8,3 systems ONLY. You CANNOT disable the AMD GPU in an iMac.) Weird colors will also be produced when running Mojave with one of these video cards installed/enabled. To disable the AMD GPU on a 2011 MacBook Pro 8,2 or 8,3, follow the guide found here.

Concerning the last sentence: "To disable the AMD GPU on a 2011 MacBook Pro 8,2 or 8,3, follow the guide found here", I might add: and here ;)

Notice that disabling AMD on that machine also means losing the ability to drive a second monitor. Bad for multi-monitor setups, doing presentations… –– Also note that while the integrated Intel HD3000 will provide you with some GUI acceleration,  (but nothing like the Metal-API, as noted in Nimesh's answer) it is known to be a bit buggy, and increasingly hardware acceleration gets blacklisted by applications like Firefox, Chrome and VLC…

So, curiously: a defective discrete GPU makes a hacked Mojave install in these machines more attractive than a working one, as with a toasted dGPU you will lose less in the process.

Whether the upgrade is worth it for his machine is another issue. In a comment you wrote that

  replaced the keyboard and the battery to get more life out of my MBP. I don't want to let go of my matt screen! And all my lovely ports!

This leaves it undetermined whether you upgraded from platter hard disk to SSD. The forced conversion to APFS renders this option undesirable on hard disks. On an SSD that might be not an issue, but I still don't like APFS and regard that filesystem as immature.

Then High Sierra and even Sierra are presumably still supported for some time regarding security updates or application compatibility. From that perspective there is no need to let go of that machine right now.

As this is totally unsupported by Apple: an early 2011 MBP might break at any time with a future update from Apple. Unless you really need a 10.14-only application –– or maybe die to get darkmode? – there is currently no compelling reason to do this if you want to work with that machine.

A final piece of opinion. If you love your machine with its matte screen, new battery, new keyboard and all those lovely ports: then experience tells me that any Mac lover is well advised to not upgrade immediately to an .0-OS-release from Apple. Do not upgrade now, wait a bit.

To accomodate the more general question title:

With a patched installer these are "the real" bare minimum requirements right now:

  Requirements:

  Early-2008 or newer Mac Pro, iMac, or MacBook Pro:
  MacPro3,1
  MacPro4,1
  iMac8,1
  iMac9,1
  iMac10,x
  iMac11,x (systems with AMD Radeon HD 5xxx and 6xxx series GPUs will be almost unusable when running Mojave. More details are located in the Known Issues section below.)
  iMac12,x (systems with AMD Radeon HD 5xxx and 6xxx series GPUs will be almost unusable when running Mojave. More details are located in the Known Issues section below.)
  MacBookPro4,1
  MacBookPro5,x
  MacBookPro6,x
  MacBookPro7,1
  MacBookPro8,x
  Late-2008 or newer MacBook Air or Aluminum Unibody MacBook:
  MacBookAir2,1
  MacBookAir3,x
  MacBookAir4,x
  MacBook5,1
  Early-2009 or newer Mac Mini or white MacBook:
  Macmini3,1
  Macmini4,1
  Macmini5,x
  MacBook5,2
  MacBook6,1
  MacBook7,1
  Early-2008 or newer Xserve:
  Xserve2,1

How can I get iTunes to recognize my iPhone 4S again without having to re-configure all my apps?

Coincidentally, that happened to me just one week ago when Wifi sync died en route. The solution is simple, but totally non-intuitive: do the exact opposite of what feels right, and all will be well (not exactly Apple’s finest hour in UI intuitiveness):

Choose “set up as new phone” on the initial screen. In the dialog that pop ups give your phone the name it had before (important – if your case is similar to mine, it will be pre-filled). This will re-register the phone with iTunes sync.
Your phone will do an initial sync with all sync options (music, movies, ebooks etc.) disabled except apps, which are set to “sync all” (if you have a lot of apps in iTunes you are not usually syncing to your phone, the initial sync will flood your phone with these. Delete them out of iTunes beforehand, or from the iPhone after the initial sync). Apps already on the phone will not be overwritten and won’t lose their settings.
At this point, all media will still be both in Tunes and on the phone, but not in a synchronized state. Re-check all your sync settings. Acknowledge the “all media on this phone will be deleted” warning. Don’t fret: as long as you are syncing with the same iTunes library as before, nothing will be deleted in the next step.
Trigger a sync manually. iTunes will compare what is on the iPhone and what it is meant to sync, and will not re-transfer media already on your phone. Once done, both media libraries will be in sync again. One gotcha though: make sure the downsample setting on the first option page is set as it was before (i.e. on if you downsample music to 128 Kb/s in sync, off otherwise), or you music will be re-synced because bitrates do not match – quite a pain if you have a large library.

After that, your phone will be back ins sync without undue hassle (i.e. worrying about out of date backups in iTunes, iCloud restore etc.).


Service to remove all white space from a string?

In Automator, create a new Service with the following settings:

Service receives selected [text] in [Terminal]

Add a Run AppleScript actions, replacing the default code with the code below:

Example AppleScript code:

on run {input, parameters}

    set selText to item 1 of input as text
    set AppleScript's text item delimiters to {space, tab, linefeed, return}
    set selText to text items of selText
    set AppleScript's text item delimiters to {}
    set selText to selText as string

    display dialog ¬
        "The selection contains " & (count characters of selText) ¬
        & " characters." & linefeed & linefeed & selText ¬
        buttons {"OK"} default button 1

end run

Save the Automator Service as, e.g.: Count Selected Characters

Now in Terminal, select the wanted selection, e.g:

Right-click and select Count Selected Characters from the Services context menu.

Example output of the selection show above:

Note: The example AppleScript code is just that and does not employ any error handling and is meant only to show one of many ways accomplish a task. The onus is always upon the User to add/use appropriate error handling as needed/wanted.


If I use Find My IPhone to check on the location of someone in my friend list, can they telll?

There is no immediate indication on the device that it is currently being tracked, only that GPS is in use by something.

Invoking the GPS will cause the location services arrow to appear in the top bar. The catch is that going into the settings, General -> Privacy, the user can tell what. If FMI is being used currently, the arrow in its box will be purple, and if it was used in the last 24 hours, the arrow in its box will be grey.

However, the user can disable the Find My Iphone feature with a simple toggle in the same menu.

Sizzling Sound on Yosemite in Multi-Output (Aggregate Device) from the 2. Device

Try making sure that your source format (Hz) and bitrate are set to the same on both devices.  My guess is that if they are different, you may have one receiving information at one rate but transmitting as another.


The "2Do" application shows a blue dot in app's titlebar on macOS - what is it for?

The button is specific to the app "2Do" which you're running. It is not a general macOS "thing".
You are not the first person to ask why the meaning of the dot is, or what it does (if anything) when pressed. For example there's a Reddit thread about it here:
https://www.reddit.com/r/MacOS/comments/aw08z5/what_does_this_blue_button_next_to_the_traffic/
However even though the manual for 2Do shows a screenshots with this blue dot - it is not explained what the purpose of it is.
I would suggest contacting the support for 2Do to find out more!


My Macbook Pro (2011) won't boot into single user mode

You may considering using these steps to start up your Mac in single-user mode or verbose mode:

Shut down your Mac.
Press the power button to start up your Mac.
Immediately hold down the following keys:

Hold down Command-S for single-user mode.
Hold down Command-V for verbose mode.

You've successfully entered single-user mode or verbose mode when you see white text appear on the screen.

Hope it works.


Most likely what you are seeing is the cached image of the app. Your iPhone takes picture snapshots of apps as they run, specifically so that when you go into the app switcher, you see a graphic that looks like the app. It also refreshes this image from time to time. Most likely, you're just seeing a stale picture.

Also on an unrelated note, with the way iOS works, closing apps the way you are doing has virtually no impact on battery life. Placebo effect possibly, but not much more.


How to get rid of a shared folder on Mac

Open a Finder window, then open preferences (Finder > Preferences...). Go to the 'Sidebar' tab and uncheck the options under 'Shared':

If you want to make sure your computer doesn't appear on other computers like this, go to System Preferences > Sharing and uncheck File Sharing:


How to be connected to two different LANs simultaneously?

Martin,

You have set up two conflicting networks in the Mac.

The way to fix this is to tell the Mac exactly what you want to do which is, I assume, to share your Mac's WiFi 'net connection over Ethernet to your Linux box.

The first thing you need to do is take out all references to a network over the Ethernet interface as Sharing will take care of all that. So if you have manually set IP addresses and such then take all that out.

Open System Preferences > Sharing and select Internet Sharing. Then in the drop down "Share your connection from: " choose "Wi-Fi" and in the box tick "Ethernet".

This should fix your problem but it might require rebooting the Linux box.


Search all archived mails in the server in Apple Mail for OSX Mavericks

I can confirm that the IOS 8 Mail app (and on IOS 7) searches all IMAP mailboxes on all 5 of my mail accounts on different servers when I use the search box via the "All Mailboxes" list item in IOS Mail. It can take a little while sometimes but it always works for me.

In Mavericks Mac Mail I leave the Inbox selected when I search otherwise it seems to search only the selected mailbox.

In the case of Gmail Archived mail it must depend upon how Google has implemented their Archive mailbox. But if it is a regular IMAP mailbox, your search will include its contents.


All contacts have disappeared from iPhone

I would start from a computer and log into iCloud.com and inspect that your account is in good order and add a contact / review what contacts are already stored in the cloud.

At that point, you can troubleshoot the iOS to iCloud sync in knowing that it isn't a problem with your account itself or a server side error.


Use the Enter Time Machine command from the Time Machine menu to restore the folder ~/Library/Application Support/Google/Chrome from a Time Machine backup made before you deleted the cookies. Note: all changes to your Chrome settings and preferences will be reset to the time of the backup.

Make sure Chrome is not running.

Here's Apple's guide to restoring files with Time Machine.


Image Quality of Images Shared via Messages MMS

Typically the size of the SMS package is controlled by the network provider but it is on average 3 Meg per message.

So a single photo will look sharp. How ever if you try to send multiple photos they have to fit in the 3 Meg bucket, and will be reduced in size.

You best option is to use Dropbox or Google drive, Photobucket ect.... if you want to send larger then 3 Meg files.

Basically select all photos and just upload to one of the services and then share (send link) to the other party.


External monitor causes very high CPU usage

There has been some unconfirmed reports that the NVIDA drivers that came with High Sierra are not operating correctly.

Suggestion is to get updated Drivers from NVIDA directly.

Some have suggested to change the resolution back and fore to fix the problem.

It also looks like your system is no doing Graphics switching.

Check in System Preference that the Auto Graphic switching is turned on.

Also it could be very useful to us if you copy/paste some 30-50 lines in from your Console at the time when you plug in the external monitor so we can see what is going on.


Anaconda macOS GUI installation changes - should I remove the old folder in the current user account?

I removed the old folder. All seems to be working.


I updated to 10.11.4 (15E65) and now I suddenly have 100 more GBs of space free?

I think you might be on to something here, the .MobileBackups folder is supposed to be invisible, but sometimes does actually take up storage space. The other thing is caches, they can easily grow to gigabytes in size, though I wouldn't expect them to take up 100 GB by themselves...

Whatever the case, if you still have your files in your home folder, then you're probably good! But I hope you made a backup before installing the update anyways, right?!


how do i disable my messages from showing up on my macbook air

Open Preferences in the Messages app and log out of your Apple ID. That will prevent your device from receiving any messages there.

Additionally you can disable message forwarding in the Messages settings on your iPhone.


Apple Mail - Making Reply and Forward Attributions the SAME?

I'd be very interested in this if you can pull it off, as that reply header format is super annoying to me.

For the previous version of Mail, a guy at Purdue wrote a plug-in to do exactly what we're looking for here.  He's since moved off OS X so he isn't maintaining the code for Lion, but it might serve as a good starting point for you.  The source is at:
https://github.com/saptarshiguha/ReplyWithHeaders

The author gave me the following tip (all Greek to me, but might be helpful to you):

  Fixing this to work in Lion might be as simple as including new UUIDs
  (plugins require something called UUID compatibility IDs), or a
  rewrite (the Mail internals might have changed).

Hope this helps!  I know a lot of people that would be very excited to fix this little shortcoming in Lion Mail.

Under System Preferences -> Energy Saver, select the checkbox "Wake for network access". Note that for Mac laptops this can only be enabled while the laptop is connected to a power source.

Accessing the Mac over the network from your Linux machine, such as through SSH, will wake the machine.


Yes, using third party tools, like Power Manager, you can trigger scripts based on your UPS state.

Thirty party tools can monitor the UPS state through the IOKit and receive callbacks on state changes; thus avoiding polling.

If you are comfortable with shell script or AppleScript, Power Manager provides hooks for scripting your UPS in these languages.

I wrote Power Manager, so feel free to ask technical questions.


10.6.8 Update Combo Failed Unknown Error

Set the date on the Mac back to to for example 1st of May 2012 using "Date & Time" in System Preferences. Remember to turn off "Set date and time automatically".

Remember to set the time and date back when you're done updating.


What bluetooth audio codec does iOS use for Airpods?

You can't tell which codec is used on iOS, but AirPods use SBC or AAC.
On macOS, you can check which one is in use by going to the Bluetooth menu, clicking on your Airpods with the "Alt" key pressed.


Sync iPhone/iPad with iTunes after library rebuild

In researching solutions, I found this discussion at apple.com in which somebody suggests "damaging" the iTunes library. This lead to a very useful post which discusses how iTunes uses the data it has to recreate what it doesn't have and gives instructions on how to damage (without deleting) the file -- spoiler: erase the data, leave the file.

Fortunately, I had backed up the iTunes files before I recreated the iTunes library.

I copied my backed up files back into the iTunes directory and launched iTunes and rebuilt what it needed to. There were no apps listed in the Apps display though.

When I connected my iPad, iTunes didn't complain about this being an unknown device. As it started to sync, it prompted my to transfer purchases (i.e. the apps on my iPad which didn't show in iTunes) -- but with no hint of having to erase anything. The sync took longer than normal, but everything is there and I can even find the songs which were originally hidden.

iPad is fine, will sync my wife's iPhone tonight.


Is iTunes for Windows affected by the code responsible for the goto fail vulnerability?

The "goto fail" bug was part of a OS X library that checked that a valid SSL certificate also matched the host records it was exchanging traffic with.

Since many applications use SSL first identify a web site securely and then encrypt the traffic, having the library in the core OS lets each program not have to do the work to validate a cert. By patching/fixing this library the problem is solved for all applications that relied on that fucntion.

On OS X, iTuned relied on the system to validate SSL certs and thus didn't need a patch. There isn't a published vulnerability listed (yet) for iTunes for Windows, so you should be in the clear for that one issue.

Of course iTunes could have other security issues that aren't published or patched yet, but there's not any evidence that Windows iTunes is vulnerable today to the same code problem.


Prompt for iOS

Prompt allows you to remotely SSH into another machine. Without jailbreaking, there is no way to use Terminal to access your file system. However, I've found that if you do jailbreak your phone and want to use Prompt as a Terminal, you can set it to SSH to server 127.0.0.1 and authenticate with the standard iPhone root credentials.

Remoter: Remote Desktop (VNC) for iOS

This app does basically the same thing just a little differently. By default it allows a VNC connection for screen sharing, but it has different add ons that you can purchase that allow SSH, Telnet, and RDP.


'Wallet and Apple Pay' missing from Macbook Pro settings

Only MacBook Pro with Touch ID have a ‘Wallet and Apple Pay’ preference pane, as these Macs are the only ones which have the necessary hardware support for storing cards for Apple Pay on device.

On older Macs, Apple Pay is still supported with a compatible iPhone. No configuration is available on the Mac, since the Mac delegates to the iPhone for Apple Pay.

To enable Apple Pay on your Mac using your iPhone, go to Settings → Wallet & Apple Pay and turn on ‘Allow Payments on Mac’.


Can I move Xcode and Android Studio to SD card

Can you? Yes.

Is it wise? Perhaps not.

Flash storage is notoriously frail. Once it fails, that's, it, it's gone, usually taking everything on there with it.

The adage "Any data not stored in at least three distinct locations ought to be considered temporary" is not one to take lightly.

Other than that - it will run like molasses from an SD card.

Flash on USB sticks/SD cards is not the same as on an SSD drive - this has a better explanation than I could possibly compete with -
SuperUser - What's the technical difference between a flash drive and an SSD?

In the end, it’s your choice what you store externally, so if other things are more vital than code, keep them on the internal storage. If code is the priority, move photos or music or video files to SD storage.


Automatically open a terminal window and run a command, robustly

Save whatever script you wish to a file and when you change the extension to .command

Finder will robustly make a command line window that’s new to run that command / script. This works for whatever #!/bin/whatever shell or script you start the text file.

AppleScript can open documents just like when Finder clicks on them to open, this should be a fairly universal way to accomplish your task.

How to reset the $PATH in terminal OS X El Capitan? tried previous posts but did not work

First, run PATH=/bin:/usr/bin in Terminal.

Then open ~/.bash_profile (in terminal, nano/vim/favorite editor ~/.bash_profile) or open Finder, then press Shift+Command+G and paste it in. Then you can comment out the path line. There is no need to delete .bash_profile in its entirety, and it isn't recommended.

You will have to click "Allow" till done, or use script that does that, but since it is usually one time action just do it manually.


How to uninstall deprecated Unsubscribe plugin from Mail.app?

UnsubMailPluginMail App for OS X is a leftover from a free program which later switched to become a user pay software. The program vanished but the plugin stayed to pop up and annoy you.

To remove it:

Open your Finder window.
Proceed to the Go menu.
Then down to Go to Folder....
Then in the window delete existing wording and type in
/Library/Mail/.

When the folder opens, locate the plugin and move it to Trash.

Flickering/Blinking MacBook Pro 2015 (While Static)

The first things I'd try are to reset both the NVRAM and SMC in that order. Before following the steps below, ensure you have no external hardware connected (so, unplug your external display) and make sure you use the built-in keyboard.

Reset the NVRAM

Older Macs had what's called Parameter RAM (PRAM), newer Macs use Non-Volatile Random-Access Memory (NVRAM). Here’s how to reset the NVRAM on your particular MBP:

Shut down your machine. Yes, a full shut down, not just logging out.
Press the power button and then press the commandoptionpr keys. You have to make sure you press these keys before the gray screen appears or it won’t work.
Hold those keys down until your Mac reboots again and you here the startup chime.
Let go of the keys and let your Mac reboot normally.

Note: When you log back in you may need to readjust some of your system preferences (e.g. speaker volume, screen resolution, startup disk selection, time zone information, etc).

Reset the SMC

To reset the SMC on your particular MBP, follow these steps:

Shut down your computer
Keep the power cable plugged in.
Press at the same time shiftoptioncontrol (on the left side of the keyboard) and the power button
Let go
Turn your computer back on with the power button.

After resetting both the NVRAM and SMC, use your computer to determine if the issue still persists.


How to set application icon using command line?

The following approach worked to replace default icon (located at /Applications/Hello World.app/Contents/Resources/applet.icns for example) of "Hello World" application created using "Script Editor" with another icns icon file (Firefox icon for example).
cp "/Applications/Firefox.app/Contents/Resources/firefox.icns" "/Applications/Hello World.app/Contents/Resources/applet.icns"
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -f "/Applications/Hello World.app"

How to import iPhone pictures directly to Flickr to save space?

Assuming you have a Flicker on your iPhone!!

Click the camera button.

This will take you to the camera screen.

To the left of the camera shutter button is a symbol that looks like 4 layered squares, click that.

This opens up your photo albums, depending on how many albums you have, but usually 'camera roll' will be listed at the top, click and open.

Click on the image you want to upload and hit the 'done' button to the top right - you now be sent to the filter page, from here you can add filters or crop. To access the editing click the pencil symbol, when you finished click done and you'll be brought back to the filters page, add filter or not, then click 'next.

Now you should be at the 'Details' page, here you can add title, description, change privacy levels, share to fb, twitter, tumblr, add location data.

If you want to add tags, add to sets or groups you need to click on 'Advanced'.

When you've finished adding at the info you need to click 'upload'. Job done :)


Is it possible to whitelist contacts using the iOS iMessage app or iOS parental controls?

There is not a way to whitelist contacts as the default in Screen Time.  However, you can choose specific contacts to whitelist during downtime.  This only gets you part of what you're asking for but, as per the comments, you wanted more info on how to do this.  The answer assumes you're using iOS 13 (wasn't mentioned in your question).  Source:

Set Communication Limits

Open "Settings" on your kid’s iPhone
Swipe down if needed and tap "Screen Time"
Choose "Communication Limits"
You can now pick communication limits during allowed screen time and downtime.  Based on the way this feature works, you may want to review your kid’s contacts to make sure you approve of all of them.

Contacts Only

The first option is to set communication limits for allowed Screen Time use. This offers “Everyone” or “Contacts Only” as the two options. When “Contacts Only” is selected, your child won’t be able to edit contacts.

Specific Contacts

The next communication limits apply to device downtime. When Contacts Only is selected for the “During Allowed Screen Time” portion, you’ll see the choice for Contacts Only for downtime or Specific Contacts.

Once you choose “Specific Contacts,” you can whitelist the contacts you’d like to permit.


Trying to install Windows 10 on early 2008 MBP without using the BootCamp Assistant

Just a thought, but can you install Win 7 using the bootcamp that is designed for your system and then once installed upgrade to Win 10?

Note that the Windows 10 bootcamp drivers will not likely support your hardware but I have had some moderate success updating bootcamp drivers on Windows installations from within Windows by identifying any unsupported hardware by their hardware ID (in device manager) and then downloading the driver directly from the manufacturer.

Power off your VM, open Parallels Desktop, select the VM you wish to modify then in the menu bar select Virtual Machine -> Configure...

You'll get a Options window where you can change all the settings of the VM.  Specifically to your application problem, you can modify those settings underneath Options -> Applications.  I'd uncheck "Share Windows applications with Mac".

After completing that step you'll need to manually rebuild the LaunchServices database.  Open Terminal and run the following (without the $):

 $ /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
 $ killall Finder


How do I turn on my iPhone 4 if the home or power button doesn't work and connecting to a power source doesn't either?

If an iPhone is off, and you connect it to a power source (either a charger or computer), it will always turn on. !!!

If that is not working then something more serious is going on. Bring it in for repair.

Just in case it is locked-up, try holding the Home button for 30 seconds, but that might be a fruitless exercise.


How can I make use of info from a `file-bookmark` entry in a plist?

The data in file-bookmarks can be converted to an NSURL object.  If you know at least a little about macOS programming, you can load this data using the UserDefaults system and parse it back into a path using NSURL's URLByResolvingBookmarkData method.

There is some Objective-C sample code over at StackOverflow that still works on Mojave, reading data from FXRecentFolders and outputting the path to stdout.  I am not skilled enough in Swift, but it is probably not difficult to convert that to some equivalent Swift.

NextDNS has an option for Google Safe Browsing. It's on by default but you can disable it from the nextdns.io dashboard.


disable temporary autoconf inet6 address

A similar question on SuperUser prompted me to look into sysctl settings, with the following setting available to prefer the permanent IPv6 autoconf addresses to the temporary ones:

% sudo sysctl -w net.inet6.ip6.prefer_tempaddr=0
Password:
net.inet6.ip6.prefer_tempaddr: 1 -> 0
%

For ssh sessions that aren't expecting any ongoing interaction, this would make it possible to go to sleep, and wake up within a number of minutes without any SSH connections suffering a disconnect (which would previously happen due to the prior IPv6 address being de-provisioned upon the wakeup from sleep).   (Don't need no mosh!)


Why does Safari cache old pages on iPhone even after you've downloaded the new page?

I would imagine this has something to do with Core Data, memory warnings, or both. If Apple is using its own kit, then it is saving the cache in a Core Data store, which is, essentially, an unordered set. My theory is that when you go to a site, Safari is going to the Core Data store and grabbing the first instance of the URL in question if it exists, which can be old, new, whatever. But since I also don't think that Apple would be nearly that sloppy, I'd say that every page attempts to cache, but the amount of data required to properly cache a site is beholden to memory warnings, which you, as the user, should never, ever see, only this time the newer page simply doesn't get cached and that's why you get random older pages in view.

Okay, that was a bit technical. In short, I think Safari attempts to maintain a clean cache, but memory limitations of the device don't always allow that to happen.


Recover Meteor JS MongoDB from Time Machine Backup

Yes - use tmutil to see if the files you are missing were even backed up:

tmutil isexcluded /path/to/the/folder

If you don't have them backed up, you'll have to redo the work. If you did have them backed up, you can copy files using terminal from the destination to your desktop:

cp -rp /Volumes/Backup/Backup.backupdb/host/2015-08-25-000102/Macintosh\ HD/path/to/the/folder ~/Desktop/

Is Time Machine sufficient in the case of a reformat?

Time Machine will be able to restore all files.
Depending on what you want to restore, you may restore the whole partition or only single files or folders.
Setting up Time Machine you may choose which folders or files to exclude from the backup.

Here is an example of the Time Machine UI:

You may navigate with the Time Machine.app in your Time Machine backup similar like the Finder does on your Mac. You have a third dimension representing time though. If you click on the up arrow you'll move backwards in time. This is also indicated on the time scale on the bottom right side.

If you now want to restore just the blue Adobe folder highlight it and click "Restore" and it will be copied to your main volume overwriting any previous file/folder there.


What happens when you walk out of range from iPhone / Macbook Pro with bluetooth headphones?

SHORT ANSWER

In a nutshell, when I'm out of range the music does not start playing through the speakers of the connected device.

LONG ANSWER

I own a pair of Bose Bluetooth headphones that I've been using with an iPhone, iPad, MacBook Pro and an iMac. I've had these for about 15 months and have been very happy with them.

The pair I own maintain a charge for about 7hrs and are able of being paired with 8 different devices. They can also be connected to two devices at the same time!

Now that I've provided that context, my comments below will make more sense.

If I connect my Bose Bluetooth headphones to my iPhone for playing music they work great. If I move beyond a certain range, the music is no longer heard on the headphones, but as far as the iPhone is concerned the music is still playing. During this period, the music is not heard from the iPhone speaker. If I move the headphones further out of range so that the connection is totally lost, then the iPhone stops playing music altogether (i.e. the pause button becomes a play button again).

However, I have had another issue that may or may not be relevant in your case. I also use my headphones for long phone calls when I work at home (usually 1 or 2 days per week). This works fine, however, if I happen to have another device within range that is also paired to my headphones (remember they can be paired to 8 devices, and connected to two devices simultaneously) then that other device may connect to my headphones. Once that happens, if I get a notification or if the other device was already playing music or a video, then this causes some sort of weird interference with my call. This interference was only happening when I was on a call, not if I was using them just to listen to music.

Now, this issue may be peculiar to my set up as there are lots of variables involved, such as:

the model and specs of headphones
the model and specs of all the paired devices
how many devices you've paired
whether these devices are in range
what these devices are doing at the time

In my case, once I figured out what the problem was, I chose to 'forget' my headphones from the other devices and now only pair/connect to them on my iPhone (as that's what I use the headphones with for 95% of the time). And if I need to connect them to another device for a while, I just connect them then. This has worked very well for me, as I rarely need to use them with another device.

I hope this helps!


Disable the sleep function of the macbook touch bar

You can use my script until Apple adds a preference for the Touch Bar.

It simulates keyboard activity by sending the command for the fn-key every 60 seconds. You should not notice it while typing. Keep in mind, however, that this will prevent display sleep / system sleep as well.

Copy and paste the following code into the "Script Editor" application on your MacBook Pro with Touch Bar:

(*
1. Save as an Application: Script Editor > File > Export… > File Format: Application
2. Check "Stay open after run handler"
3. Run the app or add it to your login items: System Preferences > Users & Groups > User > Login Items > Press the "+" button

# http://apple.stackexchange.com/questions/269174/disable-the-sleep-function-of-the-macbook-touch-bar
*)

on idle
    tell application "System Events" to keystroke (key code 63) -- press fn key
    delay 60
end idle

Please let us know if this solves your issue.


You can designate certain apps to show function keys instead of app controls (in the touch bar) by adding them in System Preferences → Keyboard → Shortcuts → Function Keys.

Related: Is it possible to set touch bar in F1-F12 mode for a specific app?


Renewed Apple developer account with wrong credit card

There isn't any issue if the payment has made though and your account is renewed. You can simply pay back your brother :)

In theory you should be able to contact Apple Developer support and ask for a cancellation, but since you said you wish to renew anyways, I don't think it is necessary. If you are concerned that your card may get charged by Apple Developer for some developer service, be assured that there's no other charges associated with Apple Developer Program membership, that may get billed on your card without your consent.

Next year, when renewing, you can use your card again. Please note not to use your brother's card again without thinking twice!

It is possible to change the payment method associated with your Apple ID anytime.


Ipod nano touch podcast sync issues (can't delete some podcasts)

The podcasts part of iTunes just manage those you have either subscribed to, or subscribed and unsubscribed but still have episodes. It looks like your issue is related to trying to manually manage these, which will let you add the files to your iPod, but iTunes really doesn't know about the structure behind them.

I would recommend having it manage them for you. In that case, you can also tell it to delete those (or keep those) you want after you listen.

For example, I have a couple of concerts from NPR on my iPod that I keep, but my other daily/weekly podcasts delete after they have been listened too.

I expect the reason you are seeing the difference between iTunes and the iPod is the way you are currently mixing the two methods.

Is it possible to use an iPhone without data?

This is most certainly possible. The first few months I had an iPhone, I didn’t have a data plan either.

In Belgium (where I live), iPhones are generally sold separately, without a data plan / SIM — they’re officially unlocked iPhones.

So, the answer to your question is: yes, it’s possible to use an iPhone without a data plan — but you can only change the SIM card if you own a SIM-unlocked iPhone.


Show thumbnails of AVI and WMV files in finder

Apparently I was a bit trigger-happy with the bounty, because after a bit more Googling, I stumbled upon QLVideo, which:

  "-- allows macOS Finder to display thumbnails, static QuickLook previews, cover art and metadata for most types of video files."

The Github page has an installer (.pkg) under the releases page, but if you have Homebrew installed, you can also use brew cask install qlvideo on command line (that's what I used — and thumbnails started generating immediately).

It even has couple of settings available:

  defaults write uk.org.marginal.qlvideo SnapshotAlways -bool XX

  Controls whether QuickLook "Preview" shows static snapshot(s) even if
  a playable preview is available. Default is NO.

  defaults write uk.org.marginal.qlvideo SnapshotCount -int XX

  Maximum number of
  snapshots to show in a QuickLook "Preview". Default is 10.

  defaults write uk.org.marginal.qlvideo SnapshotTime -int XX

  Time offset in
  seconds for thumbnails and for single snapshots. Unless the video clip
  is shorter than twice this value, in which case the snapshot is taken
  at the mid-point. Default is 60.
  This setting doesn't affect thumbnails that have already been generated - use qlmanage -r cache and re-start Finder to force regeneration of existing thumbnails.


Easiest way to scan ISBN number from books

Delicious Monster makes an awesome piece of software called Delicious Library that's intended to do exactly what you're after: scan and catalog your library (of books and other things). And it all works through your iMacs built-in iSight camera. And it works very, very well. From their website:

  “Wait, I just hold a CD or DVD or video game or book or whatever up to my webcam, and it magically reads the UPC and downloads that item’s cover and all pertinent information about it, and displays all my stuff on photorealistic shelves? I’ll take it! Right now! This is why I bought a computer in the first place! ”

Yea, it's very cool to watch it in action. Very easy to use.


Reinstalling OS X Lion after erasing the HD

You can purchase Lion at Apple on a DVD: https://www.apple.com/shop/product/D6377Z/A/os-x-mountain-lion I guess that is the only legal way to install Lion on a clean Mac.


In OSX the terminal  by default starts a login session so reads .bash_profile etc. (The GUI login process that asks for your name and password does not use shell scripts and starts no shell it is all done from launchd and the workspace)
On other Unices xterm runs a non login shell by default so they read .bashrc as the scripts that present you with your password etc at login call the login session and all terminals are sub process of this and inherit the shell environment.
From the GNU document you referred to

Invoked as an interactive non-login shell
When an interactive shell that is not a login shell is started, Bash
reads and executes commands from ~/.bashrc, if that file exists. This
may be inhibited by using the --norc option. The --rcfile file option
will force Bash to read and execute commands from file instead of
~/.bashrc.
So, typically, your ~/.bash_profile contains the line
if [ -f ~/.bashrc ]; then . ~/.bashrc; fi

after (or before) any
login-specific initializations.

How do I take a steathy picture with my iSight camera from the command line?

Use imagesnap. It can be installed with brew install imagesnap or by downloading the binary from the website.

One use for it is to take series of snapshots:

while :; do

    sleep ${1-1}
done

It doesn't crop images horizontally either. (Photo Booth changes the aspect ratio to 3:2.)

Hopefully it's not a hardware error and you can just fix this with a clean erase. Installing to an external dive may also help you determine if it's an issue with procedure or your installer vs the ssd.


Is there a good command-line ID3 tool for OS X?

If you have Homebrew installed (highly recommended), you can just do:

brew install id3lib

This installs several id3 command-line tools, including id3tag, id3convert, id3cp and id3info.  No need for python or perl scripting; just use regular shell commands.

Usage: id3tag [OPTIONS]... [FILES]...
   -h         --help            Print help and exit
   -V         --version         Print version and exit
   -1         --v1tag           Render only the id3v1 tag (default=off)
   -2         --v2tag           Render only the id3v2 tag (default=off)
   -aSTRING   --artist=STRING   Set the artist information
   -ASTRING   --album=STRING    Set the album title information
   -sSTRING   --song=STRING     Set the title information
   -cSTRING   --comment=STRING  Set the comment information
   -CSTRING   --desc=STRING     Set the comment description
   -ySTRING   --year=STRING     Set the year
   -tSTRING   --track=STRING    Set the track number
   -TSTRING   --total=STRING    Set the total number of tracks
   -gSHORT    --genre=SHORT     Set the genre
   -w         --warning         Turn on warnings (for debugging) (default=off)
   -n         --notice          Turn on notices (for debugging) (default=off)


As seen here, it is possible to clean Cached Files manually, or you can install a third-party cleaner such as CleanMyMac 3. However, I would recommend leaving the Cached Files the way they are, as it can greatly speed up load times of applications running on your computer.

Can’t connect to Time Capsule in recovery mode (Big Sur)

After over an hour on the phone with Apple, it was suggested I try to use Migration Assistant to restore from backup. That worked for me.
EDIT: While it did work, there was a major issue: While trying to run Python/Jupyter in PyCharm, I repeatedly get malware warnings that have to be manually suppressed, individually. I mean, every file associated with a Python package in the virtual environment seems to be identified as possible malware. I called Apple about the issue, but no one knew how to globally suppress the malware warnings. There are way too many files to manually suppress them all.
I found an alternative, create a new project in PyCharm, copy in Python/Jupyer files (not packages, but files I created), then add the packages needed to run everything.


Why can't the account password be same as the iCloud password?

Absent any explicit statement from Apple, it's as good as it gets: The reason it enforces different passwords is because it's a good security practice.

The fact you are able to change it later shows that they haven't implemented cross-checking in the later stage but it also shows there are no technical reasons why it has to be the way it is.


When running a script from the scripts menu, where is console output captured?

How to backup and restore iPad apps locally on a Windows machine? (without re-downloading from internet) (also resume app downloads)

This article from OSXDaily Get iTunes 12.6.3 with App Store for Mac and Windows suggests to download the special 12.6.3 version, which restores the previous lost functionality.

Also, the newest version 12.7, when connecting the first time a device, asks if you like to restore the old feature - this was the behaviour in my case.

There is no need to use the same network. Usually you can simply populate your DNS-server with the IPs and the names of the hosts in the 192.168.2.0 network.

If you restricted allowed DNS queries to a particular network (i.e 10.0.100.0/24), you have to extend this to the 192.168.2.0/24 net.

In the network settings of the devices in the 192.168.2.0/24 network you have to set up your internal DNS-server as DNS-server.


How to run secondary Skype after recent Microsoft update?

After reading Ian's answer, I find it is a great solution to this my question. I am posting my own answer just to share my findings based on Ian's link as I faced difficulty on using above answer's path and settings.

Copy the skype shortcut paste thereon to create new skype shortcut.
Rename it as you want just to distinguish from the primary shortcut.
Now, go to its properties and append following string in Target
property
Skype --secondary --datapath="C:\Login_1"
Hence the new full string will be "C:\Program Files
(x86)\Microsoft\Skype for Desktop\Skype.exe" Skype --secondary
--datapath="C:\Login_1"
Click on this shortcut and you are done.


Is there a way to pipe the `hdiutil create` into a raw stream without needing to store it first?

It doesn't immediately seem possible, no.
The hdiutil tool itself has no option to write to stdout.
It cannot be tricked by using /dev/fd/1 as the output file either.
Creating a named pipe using the mkfifo command doesn't work, as the hdiutil checks for the existence of the file before starting.
In this case it is possible easier for you to simply stream over the raw disk contents, and then convert it to a dmg on the receiving end (depending on which utilities you have available there). In your case it is a simple dmg file, so converting it is just a matter of adding a small footer structure to the end of the file after transferring it.
You could transfer the raw data using a command like:
dd if=/dev/rdisk3 bs=1m | curl -TX - PUT -H "Authorization: Token" --output /dev/null "https://uploadlink.com"

How can I verify that a DIY Fusion Drive is working as it should?

You can use the command-line iostat tool to monitor disk activity on a per-drive basis.

Runnning iostat disk1 disk2 1 will give you an output of disk activity for disk1 and disk2 every second. You'll want to change the disk identifiers to match those of your HDD and SSD.

By running this command while you write a bunch of data to your drive (the dd command can be useful for this), you can watch which drives the writes are hitting. Once you fill up your SSD, it should start writing to the HDD, and once the writes are done, you should see some activity transferring ~4 GB off the SSD to the HDD.

You can also test whether data is promoted off the HDD by reading some data off the HDD (again, dd is useful for this). Depending on how much use your Fusion drive has already had, you may need to repeatedly read the same data in order to get it promoted, but once it happens, you should see some transfer activity, once you're done all your reading.

For some more detailed descriptions of how and what to look for on a DIY Fusion drive, check out the latest posts on this Tumblr.


How can I get iTunes to automatically refresh the media library?

What you call a “design” flaw, is not such thing. It’s a design decision made by the iTunes team. Although iTunes lets you “manually manage your library”, it’s never intended to let you move things around in the filesystem, add, remove or modify files.

The premise for iTunes happiness is that you always add the items to the library and modify things from within iTunes. You have the choice to let iTunes “organize” the library (which will copy the media to the iTunes library folder and organize it there as he wants) or you can leave it wherever you originally had it, but iTunes doesn’t “read” or “monitor" the filesystem for changes. It knows things changed when the library.xml is changed, and the only application that does that is iTunes itself.

Is this the best way?

Yes and no, it has advantages, but a lot of people miss the “Winamp-like” ease of use and it’s understandable. On the other hand, it simplifies a lot of things for a lot of people. It has decently worked for quite a few years now.

But that’s the topic for another discussion. :)

How can I allow a non-root user to use ports below 1024?

If you can't change your app to use a port above 1024 then the easiest way would be to take the port it is using and map it to a port above 1024.

You can do that using the firewall, ipfw is the tool for setting the firewall. You could also do it using 'nc' - sometimes known as ncat or netcat.

There is a question here that gives more details. The thread also mentions "AuthBind" which is an open source package to that allows just this - opening ports below 1024 without granting root privileges.

How can I use my Bluetooth speaker for 2 Apps Spotify + Microphone Apps at same time?

Rex.

What will work out of the gate is to:

Start something playing in the background (including Spotify).
Open GarageBand, and make a new project to record the microphone.
On the righthand side of the GarageBand window, turn on the monitor.

It will help you to go to the Advanced section of Song Settings, and switch on "Run in Background." That way the mic will be what's in the background, not your music app.

Now you'll hear your voice on top of the other audio - there might be a really big delay between when you speak/sing and when you hear it on the speaker, but this will have to do with what hardware is involved. Turning on "Send MIDI clock" might help, and turning off all effects on the track might as well... but better would be to try different hardware.

Either Audiobus 3 or AUM should do this too - neither is a free program, however, and I didn't test them.

Good luck!


After installing Java for OS X 2014-001 it works.

http://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US


Install 2 different OS X versions on the same machine/hdd

This is entirely possible. I use either of both of the following variants depending on what I'm trying to test:

Virtual machines

You can run OS X 10.7 and newer inside recent versions of Parallels and VMWare Fusion. You can also run the server variants of older OS X versions this way; these older server variants also work on VirtualBox, which is free for personal use.

Advantages:

Run multiple versions of OSX at the same time
Should be easier to automate (script) testing
Snapshots for easy rollback to previous OS states (e.g. different patch levels, etc.)
No need to repartition your disk

Disadvantages:

Noticeably slower than natively installed OSX.
If the software you want to test uses 3D acceleration or other non-USB hardware features, you will likely run into problems. Even USB devices may or may not work properly.
Parallels and VMWare Fusion cost money (but realistically, it isn't much)
Requires lots of RAM. It's just about doable with 4GiB, but I'd recommend 6-8 or more. RAM is pretty cheap, but some Macs are limited to 4GiB or non-upgradeable.

I don't have Parallels, but when I tried it, installation was pretty straightforward. VMWare Fusion just requires the Lion Installer.app (or Mountain Lion Installer.app) from the App Store for setting up a VM. When it asks for a disk or disk image, just drag the installer .app from Finder into the assistant window.

Multi-boot

You can install additional instances of OSX on your computers, and easily switch between them, either via Startup Disk in System Preferences or by holding the Alt/Option key when you hear the boot chime.

You can either repartition your existing disk - shrink it via Disk Utility and add an extra partition during setup - or install onto an extra hard drive or SSD. This can be an external USB or Firewire drive. Some Thunderbolt drives are also bootable.

The Installer.app

It's a good thing you've already purchased Lion, as you can no longer buy it from the App Store. The easiest will be to download it on your Mac running Snow Leopard: open the App Store, ensure you're logged in with your correct Apple ID and click the "Purchased" tab. You should be able to download Lion there.

When the download is done, it'll be an App in the Applications directory. Do not run it as that would upgrade your Snow Leopard install. If going the VM route, you can use the .app directly, otherwise you'll need to extract the InstallESD.dmg from the .app bundle and "restore" it to a USB stick (min 4GB) via Disk Utility. You can then boot from this stick by holding the Alt key when you hear the chime.

I also recommend backing up the installer app, as re-downloading it from the App Store from Mountain Lion is not possible out of the box. There are work-arounds, but I wouldn't rely on them continuing to exist.


Importing into Photos: Unable to get metadata

I managed to work around this issue/bug by dragging the photos from Finder into Photos manually in batches (e.g. 200 or 300 pictures at once).


How to uninstall Java 1.8 under OS X 10.10 Yosemite?

http://docs.oracle.com/javase/8/docs/technotes/guides/install/mac_jre.html#A1096890 says

To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.
Remove one directory and one file (a symlink), as follows:

Navigate to /Library/Internet Plug-Ins and remove the JavaAppletPlugin.plugin directory.

Navigate to /Library/PreferencePanes and remove JavaControlPanel.prefpane.

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS

Done that. Looking good. I still think it's bad intentions behind not offering an uninstaller. Glad this is off my system.
Commands for the ‘Terminal’ly-inclined:
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane


Sound effects for commands completing in inactive tabs/windows

It's certainly achievable if you're using scripts, I often use

tput bel

at the point where work is complete. This will not only beep the terminal but put a badge on the dock icon as well.

In terms of handling exit codes then you can string a couple together for a different sound:

if command_or_exit_status
then
# exit OK
        tput bel
else
# not ok
        tput bel; tput bel;
fi

For anyone saying not to delete it because it's the EFI partition, it's not. "EFI EFI"(disk0s1) is the real EFI partition. The new EFI partition is just one that was improperly created during OP's failed installation of Ubuntu.

This will erase the partition and make it show up in Disk Utility(change PartitionName to whatever you want):

sudo diskutil eraseVolume JHFS+ PartitionName disk0s4

Now you can remove the partition like normal in Disk Utility(source):

  Open Disk Utility.
  Click the partition that you wish to delete under the logical
  volume.
  Click the Erase tab and make sure Mac OS X Extended (Journaled) is selected.
  Click the Erase button.
  Click the logical volume.
  Click the Partition tab.
  Highlight the partition that you erased in step 4.
  Click the ‘-‘ sign and click Remove.
  Use the drag handle to reallocate the space back relinquished
  by the deleted partition.
  Click Apply → Partition.

What is the minimum charging requirements to charge an Iphone 7. Current and Voltage

You need 5V.

The trick is going to be supplying the correct amount of current.  1.5A is probably the minimum, but you're not going to "quick charge" with that amount.  To quick charge you need at least 18W or 3.6A of current.


How do I get Split Screen to work on an iPad

Can a MacBook Pro13-inc, 2.9GHz Dual-core Intel Core i7 use CL9 memory reliably?

Personally, I wouldn't risk buying anything that is not explicitly supported. You may run into problems in the long term if the memory modules draw too much power or are too fast/slow.

You may want to check corsair.com/en-us/…, a 2x8GB memory module pack with 11-11-11-30 CAS timing (that is, CL=11, as Apple recommends). Corsair states that their "memory kits are tested at Apple Developer Compatibility Labs and work with most MacBook® Pro, iMac®, and Mac mini systems shipped in 2011 and newer."

Since you mention in a comment that you plan on installing 16 GB while Apple only officially supports 8 GB: I bought 16 GB for my MacBook Pro (15-inch, Early 2011) and it works like a charm, although Apple's documentation states the maximum installable memory is 8 GB.

Since my Mac has a non supported configuration, if I go to a Genius Appointment in an Apple Store I consequently replace my non-stardard modules with the original ones.

To summarize:

Stick to Apple's specs (speed, type, voltage, format, etc).
If other people confirm that more than the supported amount of RAM works, it is definitely worth a try. It will either work or fail, but it won't burn your computer's motherboard of anything. See this question at superuser for some opinions on this topic.

(Disclamer: I'm in no way affiliated to Corsair.)


Is there any way to Select All on a PDF on an iPad?

There are two ways on the iPad to select all text inside a PDF:

Select / highlight one word by long pressing and then tap on select all from the options that pop up.
External Trackpad:
Basically, the same approach as with the touchscreen, but instead of long pressing, you have tap with two fingers on the trackpad to select a word.

Can you stop websites from opening apps?

The link you click on is called a Universal Link and it allows the web developer to create a link that opens the associated app automatically, even if not installed.

  When a user is browsing your website in Safari and they tap a universal link to a URL in the same domain as the current webpage, iOS respects the user’s most likely intent and opens the link in Safari. If the user taps a universal link to a URL in a different domain, iOS opens the link in your app.

What this means is if you’re already on the Reddit site for example, if you click a link, it won’t launch the app.  However, if you click on a link from somewhere else, like a web search, it will launch the app.   This is the default behavior in iOS 9 and up.

While the documentation references Safari, Chrome and Firefox both respect the universal links.

You can “bypass” this In Safari on a per site basis by long pressing the link then selecting “Open in Safari”. Every link after that will open in Safari.  You can reset it by long pressing the link again and selecting “open in app”.

Because Chrome and Firefox respect the link, once you set it in Safari, the other browsers will follow suit.


Select specific tabs with Command-# key in Safari?

It's not something you can do out-of-the-box, but there are ways to hack around that. This article will give details:

http://www.andrewsavory.com/blog/2012/2423

Essentially, the trick is to create a series of scripts and use something like FastScripts (or something like Alfred or LaunchBar) to run the scripts.


Try holding down the alt key while powering on your Mac. This should yield a boot device selection.

If this doesn’t help, try booting in Recovery Mode as outlined here: http://support.apple.com/en-us/HT4718
There you can run Disk Utility to check wether your partition is corrupted.


Just noting that Safari 8 has an option to import directly from Chrome. In Safari, select File > Import From from menu bar.


Selling original RAM to OWC after installing an upgrade

Will Apple give me a hard time if I need to take my Mac in for some unrelated issue and I should therefore keep it and swap it back in should that need arise?

If you bought the product in the US, they legally cannot give you a hard time about it due to the Magnuson–Moss Warranty Act.  Specifically, using 3rd party parts cannot void your warranty. Outside the US, check your local/federal laws specific to your country.
Where the Act applies to your question is with respect to using 3rd party parts.  Specifically, they cannot "tie in" genuine Apple Parts (i.e. hard drives or memory) to keep the warranty in tact:

(c) Prohibition on conditions for written or implied warranty; waiver by Commission; No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer’s using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade, or corporate name;

The FTC has opined on this very question and I've written about it as part of an existing answer: Apple cannot void your warranty solely for using a 3rd party accessory.  Note, "accessory" isn't limited to peripheral device like mouse or keyboard, but any compatible part like memory, hard drives, etc.
Can they try to give you grief about it?  Sure.  But that's where going in armed with the knowledge of what your rights are will help immensely.  Further, speaking from a pragmatic side of things, all they (or you) have to do is simply remove the memory.  Just because you bought it with 16GB of RAM doesn't mean you must take it in as you bought it - you can bring it in with 8GB (remove the 3rd party memory).
And again, speaking from a pragmatic point of view, the odds of more than one memory module failing at the time same time is very low.  If a module fails you can remove the failed component and continue to function, so there's no need to keep backups of memory unless you're in a mission critical environment where uptime is key.

I've added this rule to the end of /Applications/Reeder.app/Contents/Resources/article.css:

iframe[src*="feedads"],
iframe[src*="doubleclick"],
iframe[src*="plusone.google"],
a[href*=".ads."],
a[href*="feedads"],
a[href*="feedburner"],
a[href*="doubleclick"],
a[href*="//ads."],
a[href*="api.tweetmeme"],
a[href*="delicious.com/post?"],
a[href*="digg.com/submit?"],
a[href*="google.com/bookmarks/mark?"],

img[src*="feedads"],
img[src*="feedburner"],
img[src*="share-buttons"],

    display: none !important;
}

Most of the selectors were taken from a CSS file posted by the original developer of NetNewsWire.

You could also block domains that serve ads in /etc/hosts.
