Using iMac in Target Display Mode with a MacBook Pro

I don’t know if it’ll work with the Mini DisplayPort. I was stuck in a nasty half boot to grey screen problem last November on my 2011 27” iMac. While I was troubleshooting I tried the mini display port and tried TDM but it didn’t work. So I bought a Thunderbolt cable and then a FireWire cable or vice versa. The Thunderbolt cable worked... but I think the FireWire worked too. Now I’m starting to doubt my memory. I was going the other direction though. iMac TDM on a MBP. I tried the MDP port w/my old 2009 MBP & the 2012 MBP. Neither worked with my iMac. It That was just my experience. It’s worth trying a TB or a FW cable. I just remember the mini display port didn’t work for TDM for me. Which sucked because I had multiple mini display cables/adapters lying around from porting my laptops to the TV but I had a tough time finding the other cables in my town. The only Thunderbolt cable I could buy was super short. That’s how I’m certain that it definitely worked. I had to stack books to get the laptop close enough.   I think I had no choice but to order the FireWire online. Hope you get it to work. :-)


Is there any way to hamstring my system?

Pulling the RAM seems a reliable way to constrain that resource.

Running in virtualization should help if you can tell your preferred stack to allocate less threads or cores, but I would question your main assumption that these are the critical bottlenecks for making your simulations valuable.

Why not let the simulations run full speed and just measure where the bottlenecks on the Mac arise. You can measure VM paging, IO statistics and time to run each job on your mac and then run a similar test on the production hardware.

If the code is 2 to 1 faster on the Mac and you don't have paging or IO contention, that should scale quite well to the measurements on the Linux hardware. I totally get the wish to control this and eliminate variables, but since systems need to be balanced everywhere - what is a bottleneck on one system / architecture is often not the same bottleneck on another.


How do I open an EPUB from an email in iBooks on my iPad?

In all cases I have tested, iOS recognizes epub files and will offer to send them directly to iBooks.

I have tested this from the email all, dropbox app as well as mobile safari.

Other apps like Evernote and AirSharing also are able to receive my epub files, so if you are not able to do this, perhaps it's an encoding issue or something about how the files are being attached to the emails and not necessarily a problem with iOS.


How do I change the bitrate field of an mp3 file?

Sorry but if the file has been encoded at the wrong bitrate, then they'll need to be re-encoded i.e. you'll need to rip them from a CD again. The bitrate refers to the amount of data that is used to store a second of audio. There is no way to increase this, in any meaningful way, once it's been created.

However if the file are encoded with Variable Bit Rate (VBR) encoding there does seem to be a common problem where the bitrate is misreported. If I'm reading things correctly it's because software like iTunes just looks at the bitrate of the first chunk of the file (which might just be silence or something simply resulting in a low bitrate encoding) and report that as the bitrate even though subsequent chunks might have completely different (higher) rates. There does appear to be a tool to fix this called vbrfix. However there doesn't seem to be an easy to get this tool for Macs.

If you are relatively confident with using the Terminal you could try the following:

Download http://http.debian.net/debian/pool/main/v/vbrfix/vbrfix_0.24+dfsg.orig.tar.xz
Decompress the file with something like The Unarchiver (macOS native Årchive Utility won't know what to make of it)
Open a Terminal window and cd to the path of the unarchived files
Run ./configure and then make to compile the vbrfixc binary
Assuming the binary compiles successfully cd into the "vbrfixc" folder and you should find the vbrfixc binary.
Run it with ./vbrfixc -log input.mp3 output.mp3.

If the file is a VBR MP3 file this will attempt to fix it by placing a blank chunk at the beginning of the file with a bitrate that is more representative of the entire file.


Apple Watch 3 - How to track movement in tennis?

we have also developed a smartwatch app for the tennis players - BestShot

It tracks both the tennis swings and the health data, combining it in a game performance scorecard, which can be accessed on a phone companion app. We have been working on it for a year and we are now testing it with a few tennis players and coaches. Hopefully you will find it useful too.


Prettify OS X console by coloring output?

you should change the Terminal.app preferences->advanced into xterm-color.
enter the following into your ~/.profile

for enable colored ls:

export CLICOLOR=1;
export LSCOLORS=exfxcxdxbxegedabagacad;

and from now, you will get colored ls output.

There is an easy fix, but it's not so elegant. You can change the default icon used for time machine disks to the icon used for your drobo disk. This can be done by swapping out the system's time machine volume icon located in:

/System/Library/CoreServices/SystemIcons.bundle/Contents/Resources

Note: this will only be an elegant solution if the Drobo is the only time machine disk you use for that machine. Be sure to back up the original Time Machine icon just incase you want it back in the future.


Boot camp assistant: Size of winddows support software download

It seems that something else must be wrong because the Bootcamp Support Software should be less than 1GB if I remember correctly.

iTunes offers this option in the sync panel out of the box, at least with an iPhone:


Tool to quickly hide/blur/redact text in screenshot?

Skitch can do this quickly. See?

Just click the blur button in the side bar and draw over your image to obscure things.

Please note that this app saves files to Evernote by default which can be a problem for sensitive content. You may want to disable it by not signing into your Evernote account or by making the following setting changes:

Set Sync -> Save New Skitch Notes to Evernote to Manual
Uncheck Sharing -> Automatically Share and Copy Link after creating new Skitch Notes


Failed to install ghostscript, during Imagemagick installation

:debug:main Privilege de-escalation not attempted as not running as root.

It seems from the error log that you aren't running as root even though you used sudo. You need to make sure you're in an admin account then use sudo port install imagemagick.


The easy way to do this would be to use Keyboard Maestro and just create two macros, one for 'q' which inserts '`' and one for '`' which inserts 'q'

It also does a ton of other awesome stuff and is one of my favorite OS X utilities, but it’s not free (there's a free trial 30 days it’s ~ $35 IIRC).

However, my guess is that you could also do it using KeyRemap4MacBook using the private.xml feature under "Misc & Uninstall"

I am not qualified to explain what needs to be in the private.xml file, however, I can point you to the documentation for
A simple example of private.xml which shows some examples and explains the format of the file.

There is also a free Mac OS X app Key Codes which you will probably want to use to help you find the correct key code values.


Yes, it is compatible with both 1000Base-T and 100Base-T. I own the Mac Mini 2018 with 10 Gbps option and have tried both configurations in practice.

It doesn’t appear to be compatible with 10Base-T, but you’ll be hard pressed to find such equipment anywhere these days.

You can find Apple’s description of the network support at the following link:

https://support.apple.com/en-us/HT208405

It similarly describes that 100Base-T is a supported configuration, while 10Base-T is not. Look at the included table for instructions on which cable types to use for the various supported speeds.


OS X - How do I remove photos from my iPhone using the Photos app after import?

I'd go for the 'not quite cave-man' approach - though still a bit manual...

Launch Image Capture.

Plug in iDevice

Select any/all photos you wish to delete

The Delete button is at the bottom of the window [the 'no-entry' sign]

After comments - the button is still there in Yosemite.
Update Nov 2015 - the button is still there in El Capitan, though it is now black & white, not red.
Picture updated to Image Capture 6.7 after further queries on the button not being there.
Update July 2016, as people are still missing this bit...
If the Delete button doesn't appear, eject & re-plug the phone.


chown to remote folder: Operation not permitted

Many foreign file systems (such as the Windows-native ones like FAT16/FAT32 etc) do not have a concept of file ownership on the filesystem level, and so the system call to change the owner is blocked with an error message.


how to select multiple consecutive files in icon view in finder?

There's no exact equivalent that I'm aware of; I usually rubberband-select a region and then command-click the ones I don't want.

Mouse down at the top left of the area you want to select, drag to the bottom right of the area, release.  A rubberband will be highlighted as you drag the mouse; all icons within the rubberband will be selected.  It's also possible to chain these by holding Shift or Option for the second and successive selections, so you can add additional selections or deselect icons selected previously.


Is there an app to ping IP's periodically to check latency?

How about a web service that will do this for you?

Check out host-tracker.com.  It will ping an IP address (or http-get or traceroute) for you from a collection of sensor sites.  It looks like it will email you error notifications.

I haven't used the site, so can't speak to how well it works.


macOS does not have a native drag and drop method to create a symlink in the same manner as creating an alias in Finder. By default, symlinks are created by using ln from the command line in Terminal.

In Terminal:

$ ln
usage: ln [-Ffhinsv] source_file [target_file]
       ln [-Ffhinsv] source_file ... target_dir
       link source_file target_file
$

For additional details, use: man ln

For a homegrown solution using Automator and AppleScript, the following is a bare-bones example of an Automator Service (QuickAction in macOS Mojave) that when assigned a keyboard shortcut, e.g. ⌘S in System Preferences > Keyboard > Shortcuts > Services, will create a symlink of the selected items in Finder at the selected destination folder that is brought up by pressing e.g. ⌘S:

This Service (QuickAction) will be available on the Services menu in Finder or from right-click Context menu, and or the assigned keyboard shortcut once an item or items are selected in Finder.

Bare-bones example AppleScript code:

on run {input, parameters}

    if input is equal to {} then return

    activate

    set posixPath to POSIX path of (choose folder with prompt ¬
        "Select destination folder for Symlink..." default location ¬
        (path to desktop folder) with invisibles)

    repeat with thisItem in input
        set thisItem to POSIX path of (thisItem as alias)
        try
            do shell script "ln -s " & quoted form of thisItem & ¬
                space & quoted form of posixPath
        end try
    end repeat

end run

The example AppleScript code assumes you have write privileges at the selected destination folder, other then the selected items source folder, and as coded only creates the symlink if it doesn't already exist. Changes can be made to the code to accommodate other options.

Note: The example AppleScript code is just that and, other then a single try statement, does not contain any additional error handling as may be appropriate. The onus is upon the user to add any error handling as may be appropriate, needed or wanted. Have a look at the try statement and error statement in the AppleScript Language Guide. See also, Working with Errors.


Does the Health App in iOS sync intraday to iCloud?

Your Health data is backed up to iCloud as part of your device's backup. (Your device backup includes data stored on your phone by apps, your Settings, the layout of your home screen, etc.)

I'm guessing you have iCloud set up to automatically back up your device each day, which it typically does each night when you're at home connected to Wi-Fi. So when you restored your phone, the iCloud backup you restored from probably had all your Health data up to about the end of the previous day.

This is different from how other apps sync with iCloud. When you (e.g.) create a new task in Things, the Things app probably saves that data to iCloud right away so that you can see it on your other devices, etc. So unlike your device backup, which was only current up to the previous night, your other apps/services that use iCloud were probably current up to the moment you experienced your problem.


How to see count of unread emails from the Mail app in the Mac OS menu bar?

So I can't live without the mail count in the menu bar. I was using mail unread menu for a while until it wasn't compatible anymore, I then used Dockstar which wasn't updated anymore either.
I finally found my gem, and finally could update to Mojave.
It is MBI, you have to compile it yourself with xcode, but it works as advertised!


Importing images from internet to new albums in iTunes

Save your image cover -> Go to the album -> Right click on the empty cover -> Get Info -> Artwork -> click on add Artwork

Or simply right click on the empty cover -> Get album artwork


If you download classes from iTunes U, there are stored on your computer hard drive. Then You can handle those files to be sync with the device you think about, with the tool you uselaly use... There no big difference.


Does macOS Sierra support the new iMessage effects

Sierra doesn't support all the effects from iOS.  I don't have a definitive list from Apple and I haven't seen one on their site.

On my Sierra I'm missing all the backgrounds and text effects.  I can see any stickers sent to me.


iPhone 4S shutting down 20-30 % - battery already replaced

Few ideas:

Have you tried a full blown factory restore?
Are you SURE everything internally on your phone is secured and exactly as it was when you first opened it? Might be worth it to open it up again and double check.
Have you contacted the battery seller? I've personally never heard of 'em, but then again I've never been in the market for a new iPhone battery. I would contact them and let them know about the issue. It very well could be that you were sent a dud.
Last resort: Get it replaced. Not sure what would've gone wrong with the battery replacement, but there ya go. Contact your cell phone service provider or an Apple Store and see if you can either get it fixed by them or get a replacement.


Bought a movie on Apple TV 2. Can't play on computer

Movies rented on your Apple TV are not transferable to any other device and can only be viewed on your Apple TV.

See here under 'additional information'. If you purchase on your computer, you can move to Apple TV, but not the other way around it seems.


Full video+audio recording with QuickTime on Mac OS High Sierra?

There are three different auto levels involved with a recording. The first two can be set from System Preferences, as shown below.

The input volume is the record level from either the built-in mic or input jack. The output volume controls level for the internal speakers other device (such as headphone) you may plug into the output jack. The third auto level is set in QuickTime, as shown below.

This is the level used monitor what is being recorded. This is not the same level as the output volume shown in System Preferences.

If you are using the built-in mic or an external microphone and the internal or some other external speakers, then the System Preferences output volume and/or the Quick time level should set to zero.

Although not directly asked in our question, I might as well add the following:

If you are trying to make a recording where the sound is being produced by the computer, then you need to plug a jumper into the input and output jacks. Say for example, you want to record video either from the camera or the screen and you want to sound to be music from iTunes, then you will to feed the sound from the output jack back into the input jack.


Can not delete individual messages from iMessage

How to delete individual messages changed a little as of iOS 8.

Hold your thumb on the message, until you see the "copy | more" bubble and pick "more" then you will be able to select messages individually and trash them.


Creating Multiple iPhone encrypted backups

You can sync (and backup) your iDevice with one computer only, so the problem of assigning different passwords doesn't come up at all.


How specific/secure/selective is Touch ID?

Apple, iOS Security, November 2018, p. 10

  The probability that a random person in the population could unlock
  your iPhone is 1 in 50,000 with Touch ID or 1 in 1,000,000 with Face ID. This probability increases with multiple enrolled fingerprints (up to 1 in 10,000 with five fingerprints) or appearances (up to 1 in 500,000 with two appearances). For additional protection, both Touch ID and Face ID allow only five unsuccessful match attempts before a passcode is required to obtain access to your device.


Unable to backup macbook using time machine

As suggested, the only solution was to back up the whole system using a rsync command, and reinstall the OS from scratch.


Binding a keyboard shortcut to shut down

You don't need to map the power button, that menu is already mapped to control+eject

Other useful shutdown/restart/logoff key mappings are below which might be of interest too

Prompt to save work and restart the Mac - Control+Command+Eject

Prompt to save work and shutdown the Mac - Control+Option+Command+Eject

Sleep - Command+Option+Eject

Sleep displays - Shift+Control+Eject

If the computer isn't responding and you need to force it to power off, you can hold down the power button for 6 seconds, you'll lose unsaved work though.

These power shortcuts are listed on the apple support pages


RBENV managed Rubies: VIM upgrade forcing homebrew to install Ruby

Ruby is a dependency for building vim with Homebrew according to the package details:

--HEAD
    Install HEAD version

But as you can see, it only requires ruby 1.8. It's installing a ruby because rbenv likely isn't returning an installed ruby when the ruby shim is called by the build package.

Given vim will dynamically link to your Ruby installation, I highly recommend you just switch to system ruby before you brew install or upgrade vim. Something like:

brew uninstall vim ruby
brew cleanup
rbenv global system
brew install --build-from-source vim --with-custom-ruby

The installer will happily use system ruby on the Mac, which has a high enough version, during installation and the resulting binaries created won't segfault if you happen to remove the specific ruby version they were built against, which is a real problem if you use a rbenv-controlled ruby at build time.

Alternatively you can build without ruby support:

brew install vim --without-ruby

But that's probably not what you want.


Will an iOS device fall back to 802.11a when 802.11n is unavailable?

The wireless chipset samples all spectrums and chooses the frequency that has the highest potential speed with a joinable SSID and won't generally switch to a different network unless there are errors or a drop.

Since the protocols are different there isn't so much a negotiation as a decision tree which of the several channels to join.


You'll need to install a third-party app like VLC or Plex to play off a Samba/SMB share. I believe VLC can read directly off a Samba share, but Plex might need you to mount the share on a computer and install Plex Server on that computer.

You can then play just about any modern video file thru those apps.

If you are limited to the built-in apps, you'll need to put your movies in MP4 format, with an AAC audio track as the first track (AC-3 surround sound can be included after the AAC track).  (I might be wrong about this for ATV 4K, maybe it supports other formats than the previous 2 ATV's.)  Then, you'll still need a computer running iTunes, load your videos into iTunes, then turn on Home Sharing in iTunes and on the ATV.


On OS X El Capitan, what is the difference between /Library/ and /System/Library/?

/System/Library is for stuff that doesn't change and is installed by Apple. Files here help the operating system run.
/Library is for things that may change and that pertain to all users on a computer.
And for completeness (although not mentioned in the question):
~/Library is where things that may change specific to a particular user go.


I haven't used the "Connect to Server" menu command in years.  I go into Terminal and type either a command or open and a URL that does what I want.  In your case, since sftp is a command, try sftp bang.bong.boom.ac.in


Can I install OS X lion on a disk that is OS X Extended Journaled encrypted?

I'd say this is more work than it's worth since Lion clearly isn't expecting to be able to deal with the new encryption scheme. You'd be better off running Lion virtually as that's far less work to do than hacking together the parts of Mountain Lion needed for file vault 2.

The obvious catch-22 is where you need to expose that disk to Lion to get it encrypted in the first place, the recovery HD placed on that drive will allow the installer to prompt for a password and get the CoreStorage keys set up to unlock that volume for the installer.

As mentioned in the comments, it's easiest to connect your encrypted Mac to another Mac in target disk mode to get the Lion installer to run (or better to just image things) - but advanced knowledge of fdesetup and the boot process also might allow other solutions. You will likely have continual problems with automatic rebooting since Lion isn't going to know how to decrypt the boot volume nor will the Recovery Boot image want to hand off to Lion since it's not supposed to know how to handle Filevault 2 drives in the first place.

Disadvantages of encrypting SSD disk at time of disposing of computer vs. at first use?

No, it won't be as effective. Encrypting before writing anything (/anything important) is the best (most secure) option, but if you miss the opportunity to do that there are still methods better than retroactive encryption.
(Note: this is mostly inapplicable to the built-in SSD in newer Macs with the T2 chip or "Apple Silicon" CPUs, since they automatically encrypt the data volume, with an encryption key protected by the Secure Enclave. Turning on FileVault on these models doesn't encrypt the volume, since it already is encrypted -- it encrypts the encryption key. However, any data stored on other volumes or other SSDs is not protected by this, so the following discussion does apply.)
When you retroactively encrypt a drive, what you're basically doing is overwriting the old (unencrypted) data with an encrypted version. Overwriting the whole disk with zeros or random data is better for several reasons:

Encrypted data might be decryptable if the key/password leaks, is guessable, accidentally gets stored somewhere else, etc. Zeroes and random data cannot be decrypted because they don't contain any (relevant) information. Encrypting sounds like it's providing some extra level of protection, but this is illusory.
Depending on how the encrypt procedure works, it might not bother to encrypt "unused" portions of the disk -- but they might still contain leftover copies of old files (Ezekiel Elin mentioned this in a comment). I don't know exactly how macOS' current implementation works, but I know that overwriting the whole drive with zeroes/random data doesn't have this problem (well... with a caveat I'll get to).
macOS' volume encryption works at the volume level, and doesn't encrypt parts of the disk outside of your data volume. And there are a few types of info that may be stored outside of that.

There's also a problem that even overwriting with zeroes or random data doesn't solve: the SSD itself doesn't expose all of its storage space to the computer, so if you erase/overwrite "everything" from the computer... you haven't actually erased/overwritten everything. Reading the hidden residual data generally involves disassembling the SSD and bypassing its controller to read from the raw chips, so it's not something people are likely to do unless they think there's something of serious value on your SSD, so you probably don't have to worry about this. See my answer here and the links in it for the gory technical details. Long story short, overwriting the entire exposed space twice is generally -- but not necessarily -- enough to overwrite all the actual data.
So, in summary: if there's something of really high value on the drive, either don't ever write it unencrypted in the first place, or physically destroy the drive before disposing of it. For reasonable-level sensitive data (e.g. your banking info), overwrite twice with zeroes and/or random data before selling/donating/whatever.


How to make secure backups using superduper?

What you can do is make an encrypted disk images on your external hard drive. You can see this image as a extra external drive upon your external drive.

If you make it large enough (like 500GB or more depending on the size of your external drive).
You can give the disk image a password (Choose 128-bit AES (and/or 256-bit AES)) and whenever you want to access the disk image, you'll be asked for the password.

In this way, there is a save way to protect your backups with a strong password.


How can I change the title of a boot image?

This is an older post, but I came across it today and figured I'd share what I found.

The 'bless' command seems to make this work. First make sure the disk is mounted, find out which folder it is mounted to, and:

sudo bless --folder <mount_path> -label <desired_label>

For example:

sudo bless --folder "/Volumes/Mac OS X Lion Install ESD" -label "Lion Install"

Whatever you put for the label is what should show up at the choose disk screen when holding option during a boot.

Note that you'll probably want to do this in addition to renaming in Finder or Get Info just to keep them somewhat in sync and make them easier to identify in either case.


Hard wired link between webcam and led indicator?

I just read another article about that on Ars Technica

Yes the LED is hardwired
But it can still be bypassed

Only downside of this article, it was only tested on "old" (late PPC, early Intel) macs.


Backing up entire drive (10.4.11) to FAT32 external for complete wipe

FAT32 isn't up to faithfully preserving Mac permissions, links and metadata. If you cannot repartition the drive as GUID/HFS+ it would be best to make a Disk Image on the FAT and back up to that image.

If your drive was 120G and had at least 10G free space you should be fine with settings like this to create the image. The sparse image is nice since it only fills as files are copied but it can expand to the size specified if needed.

Then you could then use Disk Utility to "restore" the data from Macintosh HD to the mounted image file. The HFS+ data would all be properly encoded and stored in one big file on the FAT drive. I don't know file size limitations on FAT anymore so that would be the one flaw in this plan if you needed an image larger than could be stored on the drive as formatted.


Is there a way to keep my iPhone from receiving calls/texts/alerts while listening to music?

Coming in iOS 6, you'll have the option to set "Do Not Disturb" mode in the device's Settings.  DND allows you to block out a time window where calls and alerts will be silenced.

You can optionally configure it to allow calls from "favorites" or repeated calls to still come through.


El Capitan, Finder.app, and Fan Performance

Same here, apparently it may have to do with Path Finder + Finder combination, I'm reading on the PF forum... I'll check it out more in detail later.

Can I view my Xbox 360 Screen on my Mac by using an HDMI to minidisplay port adapter?

You cannot use the minidisplay port for input. Your best chance to get video input on your Mac is by using a video capture device (from Elgato for example).


Are local backups of iCloud photos and camera roll redundant?

"iCloud is sync, not backup" that is an argument I've heard whenever things go wrong in iCloud syncing etc. Backup is always good. You'd value it when you'd need it.

  Does icloud photos strip any metadata or change the quality?

None that I've observed so far. All my photos sync across iPhone and Mac and I do edits etc., on both of them. Metadata is not lost.


You will need an OS that can read the HFS+ filesystem. If you are running Windows, give MacDrive a try. You will have a trial period which will be plenty of time to allow you to at least pull the contents of the drive.

Once you access the Time Machine partition, look for the following directory: Backups.backupdb. In there, you will see a folder named after the machine you used to create the backups (e.g., cqm's Mac). Navigating into it will show a list of all the backups, each folder having a unique time stamp. Going into those folders will provide you with the general structure of your Mac (folders like Applications, Library, etc.). You'll want to go into Users and then your username. From there, just browse the contents and pull the files you are in need of.

Time Machine works by hard linking the files (saves space), but the general structure is identical to that of OS X. So finding things shouldn't be an issue.

Hard linking is a neat feature often overlooked. Unlike symlinks, which create a pointer at the OS level to the original file, hard linking actually creates a pointer at the file system level, so for all intents and purposes, they are treated as one file. Let me explain.

When a file is written to the disk, a pointer to that information is also made. When you, for example, delete something, typically the system just removes the pointer. But the data still remains on the disk. This is how recovery software works. It scans for the data and restores that pointer.

Hard linking, creates another pointer to the original data. If you remove one hard link, the other will function without problems (unlike symlinks, which are destroyed when the original file pointer is removed, resulting in a broken link). Finder won't differentiate between a real file and it's respective hard link, but you can see what files are hard linked using the ls command:

-rw-r--r--  2 cksum  staff  24806 Dec 27 12:02 icon.png
-rw-r--r--  2 cksum  staff  24806 Dec 27 12:02 icon2.png

As you can see from the above example, the "2" before the username (cksum) denotes that they are hard linked. If you created another hard link (e.g., icon3.png), that number would change to 3. Run an ls on any folder and you'll see that all the files will typically have a 1 before them. This means they are not hard linked.

As I said above, Time Machine uses hard links to cut down on the space it requires. And you can do the same. Rather than copying files or working with symlinks, it's possible to hard link content all over, and have your computer treat them as unique content. The beauty of this method is it will not inflate the data stored on your hard drive, since no new data is being written, just a new pointer.


Will a US bought iPad (newest) on Verizon work in India?

Recently, Airtel Launched 4G/LTE services in Bangalore, but it made no difference to iPAD 3 community. When I contacted Airtel technical support, they offered me a LTE Indoor Wireless Gateways. Their claim is that one can carry LTE wifi-spot along with iPAD  not a bad idea for those who are travelling with all their electronic gadgets.

Technically, new iPAD now supports 700 MHz and 2100MHz LTE bands, and in India, DOT has allotted 2300 to 23400 MHz spectrum for BWA/LTE. Secondly, difference is of-course LTE technology modes namely Time Division Duplex (TDD – also called as TD-LTE ), Frequency Division Duplex (FDD – also called FD-LTE) and half FDD. Apple LTE Specs are following for AT&T & Verizon FD-LTE network configuration, and Airtel got a TD-LTE network. So all new iPad 3 users in Kolkata and Bangalore will have to settle down for a 3G network.

In India 2100 MHz band is used by defense is about to vacate 5 MHz for BWA sooner or later. 700 MHz band is used by BSNL, Defence and other disaster management agencies, about 40 MHz bandwidth is used and TRAI has recommended to get this frequency band vacated for BWA usage.

BSNL had opted itself out of BWA/LTE space, which will make private players to dominate and bring in their price plans. Further, it will be interesting watch others including Qualcomm, Infotel (Reliance subsidiary), Aircel and Tikona who have won e-actions during mid 2010, and their plans on LTE deployment. Missing harmony between spectrum winners will result in issues in interoperability, and end users will have to bare that pain. It will be similar to current TV Set Top Boxes stories, they are not portable between satellite dish service providers, though equipment are generic.

But, it’s not because Airtel which uses TD-LTE technology, iPAD which wont able to connect (as one Airtel communicated to me) but because of frequency band which iPADs built with (700 & 2100 MHz) and DOT allocated (2300 MHz). I wish, Apple to push new baseband update (aka modem firmware – not sure about other dependencies such as Antennas and etc) with 2300 MHz band offered by DOT for BWA. There is difference between India operators and American operators, American Operators spend in millions for interoperability and Field Testing. FT is also done in India, with much reduced scope & coverage. Remember they have also invested in huge for spectrum, equipment and other assets, so they surely have done due-diligence to confirm deployment obligations from DOT/TRAI/Government to protect end users like you and me.


New SIM card does not support data traffic in old iPhone

I heard back from the carrier. They informed that the subscription for the new SIM card only accepts 4G connections and not older. So these types of subscriptions will work for iPhone 5 and newer, but not iPhone 4S and older.


iPad and MacBook Pro won't both connect to my wifi

The router IP might not be http://192.168.0.1

On your Mac go into System Preferences and select Network then Wi-Fi in the left hand list.

Just under the Status: line it should tell you your current IP address, make a note of it.

At the bottom right click on Advanced. Now select TCP/IP and Configure IPv4: should be set to Use DHCP. This pane will also tell you your router address a little further down.

Now you can point your browser to the correct IP address for your router and see what it is saying.

You can also open up Settings on your iPad and go to Wi-Fi then click on the little 'i' in a circle icon and it will tell you the IP address it is using and the address of the router.

If the IP address being used by both is the same then there's your problem.


Remove separator and last opened apps from the dock

Drag the folders away from the Dock and wait until the cursor changes to indicate they will be removed, and let go. You have to do this one at a time for folder stacks as Monomeeth says.

To prevent minimized windows from showing to the right of the separator, go to System Preferences > Dock and check the “minimize windows into application icon” setting.


Can I replace the logic board in a 17" 2009 MacBook Pro with one from a 15" 2009 MacBook Pro?

As far as I understand your question, you say that you have found a 17" 2009 MacBook Pro that has a working LCD panel, but not a working system. You already have a working 15" 2009 MacBook Pro, and you want to know if you can transfer the system board from the 15" MacBook Pro and connect it to the 17" LCD in order to get a working system with a larger screen size.

The answer is unfortunately no, that won't work. The 15" and 17" logic boards are vastly different, and will not support each other's displays.


macOS native VPN can't cifs:// into file server on another network

Use smb:// for file shares and vnc:// for screen shares. I’ve not had good success with cifs:// and Finder.

If smb fails, check for open ports using network utility and look at the console on Mac and error log on the server/Linux/pc side. Network utility will show you if you have an ip / network conflict. The vpn possibly can’t route any traffic correctly if both non-routable networks conflict. Either the local or remote will have to change NAT range or move to IPv6.


Not receiving anything in Mail.app inbox

It's possible that your mailbox quota may have been exceeded, thus making it so you don't receive any new messages. If that's not the case, then I would completely remove the account from Mail or explore around ~/Library/Mail and edit/remove some files if necessary.


Apple never releases information about memory. The current rumour is 512 MB. You should wait until some opens it up (e.g. iFixit).

And there you go . iPad-2-Wi-Fi-Teardown. 512 MB of Samsung manufactured RAM.


Assuming you don't require them to open literally simultaneously, but simply rapidly, this is quite doable.

First, add the iCloud Tabs icon () to your Safari toolbar, if it isn't there already. To do this, right-click the toolbar, select "Customize Toolbar…", and drag the icon to where you want it.

Once the icon is in your toolbar, click it. A list of tabs open on your other devices will appear. To quickly open lots or all of these pages in Safari, simply hold down the command key (⌘) while you click each site you want to open.

Command-clicking a link, bookmark, or other reference to a page will, by default, open it in a background tab. If you find, when you command-click one of the items in the list, that it opens in the foreground and closes the iCloud Tabs menu, either shift-command-click, or deselect "When a new tab or window opens, make it active" in Safari's tab preferences (Safari > Preferences… > Tabs).

Edit: The third-party tool CloudyTabs is a menu bar application which includes the ability to open all your iCloud tabs at once. (h/t Matt Sephton for finding it!)


How can I download WWDC 2013 videos straight to my iPad?

Not really a way to how to download them directly. In order to get in touch with your iPod, iPhone and iPad using a computer is actually iTunes since iTunes will sync the iOS Software.

This is a common issue with Apple Wired Mice (a.k.a. Mighty Mouse) products. There is no permanent fix, the issue happens when the mouse gets dirt from your fingers building up in the mechanism, and eventually jams.

You can fix it temporarily by following these instructions. There is a section "Magic Trackpad, Magic Mouse, Wireless Mighty Mouse, and Apple Wireless Mouse, Wired Apple Mouse, Wired Mighty Mouse", the instructions are in the second paragraph:

  If the scroll ball on your Mighty Mouse has become discolored or
  dirty, use a clean, lint-free cloth lightly moistened with water to
  clean it. Wipe the ball and the surrounding area, making sure to
  rotate the ball itself to ensure complete coverage. If the scrolling
  feels rough or if the scroll ball isn't scrolling up, down, or
  side-to-side, hold the Mighty Mouse upside down and roll the ball
  vigorously while cleaning it to help dislodge any particles that might
  have collected on the internal hardware. Watch a QuickTime movie
  demonstration of this procedure. (The movie is approximately 600 KB.)


Who can I contact to discuss adding features to Apple's operating systems?

If you are suggesting new features or enhancements, try:

http://www.apple.com/feedback/

If you are reporting bugs, try:

https://bugreport.apple.com/

If you need to discuss extensive changes or a new direction you believe Apple should take, I suspect you will have to apply for a job with the department you believe your ideas will have most value in, and then find those who make the design decisions, and convince them that your ideas are the best direction going forward.

Can I upgrade the SSD drive in Mac Mini M1?

Both the memory and the SDD are not upgradable. Storage can be expanded by adding an external drive. Apple specifications state the internal drive has speeds up to 3.4 GB/s. Samsung specifications state the X5 Thunderbolt 3 SSD has speeds up to 2.8 GB/s. So storage can be expanded by adding an external Samsung X5 drive, albeit at a 18% drop in speed.
I am using a 2018 Mac mini with a 256 GB internal SSD. I quickly learned this was not enough storage. A 500 GB Samsung X5 SSD was added. The Mac was configured so macOS resided on the internal drive while the each user's home folder resided on the Samsung X5 drive. This allowed macOS to operate a maximum speed, while there was sight drop in speed when accessing user files.

Note: The Samsung X5 drive has TRIM support when used with macOS.

I should point out that at the time of purchase you can upgrade the 2020 Mac mini to an internal 1 TB SSD for $400. Samsung's list price for a 1 TB X5 SSD is also $400.
A user's home folder location can be set from the User & Groups pane of the System Preferences application. See the article Move Your Mac's Home Folder to a New Location.


How can I prevent the iPad from getting my iPhone texts or calls?

Energy saver 101 : sleeps after or when battery is at x hours?

It means the computer will sleep after an hour.
The computer (if it's a laptop) will automatically hibernate when the battery is very low (this is hibernatemode 3). Is that sufficient or do you really want the computer to sleep when there's 1 hour of battery left?


Recieving Error Code 60 connecting iCal to OS X Server

This may help:

Open iCal on your client computer > Preferences
Go to the Accounts tab
Go to Server Settings tab
Make sure there is a port number entered. It should match the port number being used by the iCal server. Originally, this setting was on "Auto" and it worked fine. The "Auto" option no longer works. Also, be sure to check "Use SSL" if you are doing so. (In my setup, I have it on port 8443, with SSL on.)

Also make sure everything has been updated.


How do I get dual colour theme for numerals duo watch face?

Source:

Apple Watch Series 3 running watchOS 6 are limited (at this time) as to the colors used in the Numerals Duo face.  S4 and above can have multiple colors.

S3 watches can also use the Numerals Mono face.  That's just an outline of the numbers with no color fill.


Where should a command line tool store cache files in OS X?

It depends on the type of data being cached - is it per user or system wide?

If per user, there's nothing wrong with using a dot-prefixed directory in the user's home directory (that's what it's for, after all, and very much the UNIX way) or perhaps /tmp/<username> if the data is not to be persisted. If it's system wide and meant to be persisted, check the hier manual page - /var/db/<appname> may be an option?

One other Mac OS-specific option is to use /var/folders (as documented in hier(7)). As mentioned, you can retrieve the user-specific temporary directory by calling getconf DARWIN_USER_CACHE_DIR.


CHM reader with Dropbox/Google Drive support in iPad?

This app looks to be your best bet. It has very limited reviews and very mixed feelings towards it.

It supports opening .chm files from Google Drive, but from one of the reviews, it has a bunch of ads that prevent viewing the files. You might need to pay the IAP (in-app purchase) for the "Pro Version." I'm not suggesting you do, as I haven't used it, but it is worth a try.


Clipboard paste hangs application for 30s

Open the Terminal application, found in /Applications/Utilities/

This will terminate and relaunch the pboard process, which is the clipboard daemon for Mac OS. This should resolve your issue.


What's the better way to expand my small SSD?

A traditional USB flash stick will not cut it for your purposes. This is not a question of R/W speed. Regardless of the R/W speeds (I own an excellent 128GB PNY Turbo stick), the on-board controller (the microchip that serves as the brains behind the drive’s operation) is built for low-cycle I/O operations. If you plan to run virtualization software from an external drive, with portability/size being the caveat, your best bet is purchasing an mSATA-based SSD with an exclosure.

Here’s a good image to put the size into perspective:

Bottom line: you won’t be able to reliably run a VM from a USB based flash drive. You need a dedicated external drive with a controller engineered to handle the operations you plan to execute.

I would assume the same procedure would be followed as the answer posted to this question
"Merge Partitions with Disk Utility in El Capitan Gives operation Failed error".

In other words, the commands would be as shown below.

diskutil  erasevolume  "Free Space"  ""  /dev/disk0s7
diskutil  erasevolume  "Free Space"  ""  /dev/disk0s6
diskutil  erasevolume  "Free Space"  ""  /dev/disk0s5
diskutil  erasevolume  "Free Space"  ""  /dev/disk0s4
diskutil  cs  resizestack  F6E64063-7D4B-4D75-AAC5-C4D128919CD3  0

  Note: You need to keep partitions disk0s1, disk0s2 and disk0s3.

I would advise executing the command diskutil list after entering each of the above commands. If something unexpected happens, send me a comment.


Why do m4r ring tones show up in Library in Finder, but do not show up in iTunes?

iTunes uses a database to track the contents of your library, not the file system. Adding the files to the folder isn't sufficient to make them show up in iTunes, you have to "import" them in to iTunes as well so they get added to the database.

To add your ringtone files to iTunes select File > Add to Library... from the menu or press Command+O.

Navigate to where you downloaded the ringtone files and select all of them in the finder dialog box.

Press the Open button to complete the import process.

You should now see them as ringtones in the My Tones section in iTunes.


Macbook Pro with External Monitor Keeps Readjustng

The displays's physical connection is disconnecting and reconnecting causing the Mac to automatically detect settings from the display upon re-connecting, this seems to indicate a physical hardware issue.

Monitor Cable:

First  make sure the cable is securely attached to the monitor too.

Failing that, I would try a different cable and see if the problem persists, there may be a short or continuity issue in the wires within the cabling.

Monitor:

Additionally try a different monitor and see if the problem persists, it is entirely possible that the Monitor's internal electronics may be failing.

The MacBook Pro:

If the problem persists after trying another cable or monitor it may be an issue with the DVI port or even the connection of the DVI port to the motherboard on the MacBook Pro.

If you try gently applying very slight force to the cable end near the MacBook Pro while the monitor is connected in directions such as: up, down, left, right, etc and that causes a change in what your observing, the DVI port may be failing.


Cannot install apps via macOS Big Sur App Store

Okay, I found the solution. I found an Apple Developer forum (that I had to access via Google cache for some reason) that discussed related issues.
To re-iterate here:

Sign out of Mac App Store

Store > Sign Out

Navigate to ~/Library/Caches in Finder

Keyboard Shortcut Cmd+Shift+G (Go to Folder)
Enter ~/Library/Caches

Click "Go"

Find the following folders in the Finder window and move them to the trash

com.apple.appstore
com.apple.appstoreagent

Reboot

 > Restart...

Launch Mac App Store & Sign in

Testing App Store downloads/installs after the above steps seems to have resolved the issues.


What are the advantages of Time Capsule over Airport Extreme with an external hard drive?

As above the Time Capsule is the easy solution.

I can only really comment on your second point, I bought one about 3 years ago and 18 months ago the hard drive failed, it seemed to be a known problem as Apple replaced the Time Capsule free of charge even though it was outside of the warranty period. What could not be replaced however was the 18 months of backups as Apple would not have replaced the Time Capsule had I opened it up to get a the drive and try to recover the data. So after that experience I won't be buying another Time Capsule.

If you are not particularly after a router there are now other companies that offer Time Machine compatible network storage, which may be worth looking at.


Can iOS apps read your clipboard, and can it be stopped?

Any iOS can always access the clipboard, there isn't really a way to prevent this from happening. Recent iOS versions show a little info box at the top of the screen when this happens so you should be at least aware if an app does this "in the background".
PS: An app can not access clipboards on other devices. What happens with Handoff is that the clipboards are synced across devices by the OSes (macOS and iOS) in the background so that at the moment an app access the clipboard it may get the content you just copied into it a few seconds ago on your Mac.


Without knowing if Apple Techs fully evaluated the state of your system (you seem to have asked someone the repair cost), in the past batteries will swell and cause odd keyboard behavior before proceeding to various other bad effects including:

  Warping the back cover
  Leaking acid into the internals

Not saying I am right or wrong, but you have a chance to get ahead of this if it is true.


A junk mail that don't want to be deleted

Recommended Bluetooth Receiver for Speakers?

Yes, indeed there are a few bluetooth receivers out there you can buy.

Altough I don't own one, products made by Logitech never disappointed me. So I'd recommend the Logitech Wireless Speaker Adapter for Bluetooth Audio Devices. It also got good customer reviews on amazon.com.

It features the needed 3,5mm Headphone jack and supports many bluetooth devices(including Android phones and iPhones).

But please do your own research before asking these questions and check out this guide. Stackexchange is not the platform for shopping questions. Also see this site for further information.

Sites that I find useful before purchasing hardware are The Wirecutter and the subreddit /r/BuyItForLife. The last one especially is the place to go for such types of questions.


Mac boot menu not showing up with different keyboards

I also use a non-mac keyboard and have seen the issue where it skips the boot menu. The native keyboard works both from a cold boot and a soft reboot. The 3rd party keyboard only works from a cold boot and not from a reboot. You should be able to power down your Mac and power it back on and have the boot menu work with any keyboard.

I've also read a few places that it matters which USB port you use for the third party keyboard (for the boot menu specifically). You could try moving the keyboard around to see if you get the desired behavior. YMMV.


These are for the most part physical network adapters which exist within your computer. Even if you remove them all from System Preferences --> Network, ifconfig will still report them all.

VLAN Configurations

While you can't add or remove hardware ports with networksetup, you can enable and disable devices with networksetup -removepreferredwirelessnetwork <device name> <network>

You can get a full list of the available networksetup commands with man networksetup and some nice examples.

If you really want to disable the hardware completely so it doesn't show up, get out your Torx screwdrives and a solder gun. Why would someone want to do so? For the same reasons, one might disconnect iSight Camera or the microphone. If you aren't going to use an interface (particularly a wireless one), it's a constant security hasard.

For VMware and other virtual machines, you'll want to remove their .kext extensions which install virtual interfaces. While I'm on board for disconnecting microphones and video cameras, I don't think removing network interfaces would help much as your computer is vulnerable as soon as it's online. If I did want a truly secure computer, I'd make sure it simply had no networking hardware inside or on the motherboard. This probably means stepping back a few generations.

This kind of secure box should then be kept in a physically secure location. I know a lawyer with a safe room in his office where just such a computer stands. It never touches the internet or any other networking device. If he wants copy out of it, he doesn't use a removable device such as a USB card or a floppy drive. He prints. If he wants a digital version, someone scans and OCR's the printed output.

If I take the hard drive out of my macBook Pro and put it in a non-apple laptop, will it boot?

It won't boot, building a hackintosch machine takes more effort than just swapping a hdd.
Macs have a different bios than windows pc's and this is not stored on your hdd but in the machine itself.
Osx needs this special bios to run and "talk to" the components of your mac.
Also, osx might not have the drivers available for the components in your pc.

you could google for info to make a hackintosch


What attachment do you need to plug the Apple EarPods that came with the iPhone 8 Plus into a Samsung Galaxy Note 20 Ultra (USB Type-C)?

You will need a Lightning to USB Type-C adapter, such as

This adapter claims to work for connecting EarPods to a MacBook. It doesn’t mention your Samsung phone, but this is the necessary physical conversion required.


Attaching OneDrive File to Email in Outlook App

This modal is unrelated to iOS Files app — it’s a custom presentation by the Outlook app. The app displays common account providers in the list to help promote the ability to log in to these providers for the purpose of attaching files, with the ‘x’ button to dismiss this.

The ‘normal’ way of adding a storage provider to Outlook with or without actually having a file to add is through Outlook’s settings. Open Outlook’s settings using the gear icon from within the app, then choose Add Account followed by Add Storage Account. You can then choose a provider from the full list of available providers.

Is there a configurable "word-of-the-day"-screensaver/ -widget

AFAIK - there's word-of-the-day screensaver that comes packed with every Mac OS X (since Tiger). You can configure it on a "per dictionary" basis. So if you need a limited list of some words, just create your own dictionary, install it on the system and I believe you'll be able to use it in a screensaver yourself.


URL Scheme for switching between 3G and 4G

Do you have an app called Launcher?

  Launcher with Notification Center Widgets by Cromulent Labs
  https://appsto.re/gb/iLR81.i

You can create a custom URL Scheme and add it to your Today Widget

Paste the below into the URL textbox and give it a name.

Cellular/Mobile Data:

prefs:root=MOBILE_DATA_SETTINGS_ID

This gets you to the "Mobile Data" section.

I'll see if there is a path to "Mobile Data Options" -> "Voice & Data"

See this post: https://stackoverflow.com/q/8246070
You could try getting to the settings page for the network


You can't normally install command-line software without administrator permissions. Do as it says and run with sudo, and you will be able to proceed.

This isn't "forcing" it, it's just elevating your permissions to do something that isn't safe to have accessible to non-administrators, thus requiring sudo.


macbook Random reboot and forgot the time

Time to swing the voodoo chicken.

Things to try, in increasing order of intrusiveness:

1) PRAM reset: Reboot machine, holding Command+Option+P+R. Machine will begin to boot, and then automatically reboot itself. Let this cycle continue for 2-3 reboots, then let go and let the machine boot normally. Yeah, I know.

2) SMC reset (the more likely one): http://support.apple.com/kb/HT3964

It's entirely possible that the SMC itself is malfunctioning, which would require a logic board replacement. From your description, I think it's unlikely that this is a software-related issue.

How to find the hashed password from the 32 character password keychain shows me?

It's not quite clear from your question whether the password you need is actually stored in Keychain itself or elsewhere.

As a general rule in security, if a password is recognised by a mathematical hash, then it is never stored anywhere in plaintext.

The result of the hash is stored, not the actual password - so that when the correct password is input by the user, the hash of that input matches the stored hash result. Doing it this way means that brute force is the only way to 'guess' the password; it can never be reverse-engineered.

Having said that - Keychain does store original passwords for you & these can be retrieved from Keychain Access by selecting the appropriate entry & entering your keychain password.
Keychain Access is in Applications > Utilities
Keychain does this by encrypting the entire keychain using a separate hash structure & can be locked/unlocked by anyone with the appropriate password.


Time Machine - can it share external drive with Windows backups?

Your preferred setup is not possible: OS X can't share an NTFS disk with Windows for backup because Time Machine needs HFS+ (from http://support.apple.com/kb/HT1427):

  Manually preparing a new disk for Time Machine

  (...)

  If you want to partition the disk, click the Partition tab and
  select a layout. Make sure "Mac OS Extended (Journaled)" is selected
  in the Format menu for the partition that will be used for backups.
  Click Apply.

Luckily, you don't need two separate drives. Using partitioning you can trick your computer into thinking it is connected to more than one drive, although there's only one. In this case, two partitions will suffice, one HFS+ and one NTFS.

(Why only one NTFS partition although you back up 3 Windows computers? Because Windows stores backups in folders named after the computer name  so there are no conflicts whatsoever (see this post). You can use one NTFS partition to store backups of multiple Windows computers.)

I'd recommend that you create the HFS+ partition on your Mac first, then, on your Windows computer, format the other partition to NTFS:

Plug your drive into your Mac.
Open Disk Utility (in Applications/Utilities).
Select the drive and select the Partition tab.
Create two partitions. Format the first partition as HFS+ (and give it a name like "Time Machine"). Leave the other partition as "Free Space". See  here for more details.
Eject the drive and plug it into your Windows computer.
Format the second partition as NTFS.

When you're done, plug the drive again into every Mac/Windows computer and select the corresponding partition as backup drive (see here for OS X and here for Windows).

To prevent the NTFS partition from being mounted every time you connect the drive into your Mac add this entry to /etc/fstab (as explained here):

LABEL=BACKUP_WINDOWS none fusefs_txantfs noauto

Replace BACKUP_WINDOWS with the NTFS partition name.

This setup works like a charm.

I have a very similar configuration:

My external 1 TB drive, which I use for backing up my Mac and my wife's Windows PC, has two partitions called "Time Machine" and "BACKUP_WINDOWS":


Is it possible to define the width/height of a Terminal window with this command: osascript -e \'tell application "Terminal" to do script

Open a Terminal window and position it on the screen where you want it and resize it to the size you want.

Then in Terminal, execute the following command:

osascript -e 'tell application "Terminal" to get bounds of front window'

It will return a four-item list of integers, e.g:

0, 22, 730, 531

Now move the Terminal window to a different position on the screen and resize it.

Then in Terminal, execute the following command, while substituting the actual list returned from the get bounds command, e.g:

osascript -e 'tell application "Terminal" to set bounds of front window to {0, 22, 730, 531}'

You'll see that the window gets repositioned and resized to what it was when you ran the get bounds command.


You can download Ukelele. It is an free keyboard layout editor, and you can make a new layout for your keyboard where simple redefine the keys. In the package are sample keyboards and a manual/tutorial too.


Best method to disable Radeon card in 2011 MacBook Pro?

gfxCardStatus disables the automatic graphics switching that macOS performs when a high performance application wishes to use the discrete graphics. When macOS boots, it detects both GPUs and uses software to switch to the discrete graphics when required. Since both GPUs are detected on boot, both GPUs are powered up, though the discrete graphics quickly switch into a lower power mode until required.
Disabling the discrete graphics using the kext method completely disables the discrete GPU so it doesn't power on. This is especially useful if the GPU has an issue that causing the machine to kernel panic. The gfxCardStatus method wouldn't prevent this, but the kext changes would.


Prompt for encrypted disk password on startup

You can remove yourself from being able to unlock the disk:

Touch ID doesn't work after several tries

Put your finger in different positions on the sensor.
This video seems to explain it very well.

Also take a look at Apple's documentation.


Mac requires password every time I wake it

You didn't say where you set the preference, or your OS X version.

System Preferences → Security & Privacy → General has a setting:

In OSX 10.9 / 10.10: "Require password Immediately after sleep or screen saver begins."
In OSX Mavericks: "Require password for sleep and screen saver", followed by the time.

That item should be turned on and set to your preferred time.

If it already was, turn it off, quit System Preferences, then relaunch System Preferences and turn it on, then set your preferred time.


cannot add shortcut to switch to desktop 2 when apps are fullscreen on 10.8.4

Full screen apps do not count as a desktop.

So if you set up looks something like the above, you can not switch to desktop 2 because there isn't one. What you have is one Desktop and two spaces.

If you want to be able to switch between full screen apps, without cycling through each space you could change your Mission Control settings.

By checking the highlighted box you can switch full screen app spaces by using the command+tab keyboard shortcut.

Also, in order to create a shortcut for Desktop 2 you need to have at least two desktops running open before you open System Preferences.


The answer, unfortunately in your case, is "no". Apple's Mail.app does not have the ability to group maiboxes by account rather than by function.

Any mailboxes other than these "special" ones stored on IMAP servers do get sorted by account, down in the sidebar section where mailboxes that are stored "On My Mac" are listed.

Thus, if you set up IMAP accounts so that Mail.app does not store "Sent", "Drafts", "Junk" and "Trash" mailboxes on the server but rather stores them "On My Mac", you could sort of simiulate some of the look that you want and those IMAP mailboxes would get listed down with any other IMAP mailboxes that are on the server. However, set up in this way, the functionality of the various menu commands and automatic things that Mail.app does with those folders would not work (well they would "work" but just not using the IMAP mailboxes), and you would have two sets of all these "special" mailboxes listed in the sidebar - those on the servers below and those stored locallay listed above all grouped together in the manner you don't like.


Non-existing URLs redirect to "searchguide - level 3" in Safari

One reason could be that you are using Level3’s DNS servers (4.2.2.1 through 4.2.2.6) which will redirect you to their search engine for any unknown domain name.

Change it back or choose one of Google's public DNS server, for example 8.8.8.8

After renewing IOS developer membership, my apps are "pending contract"

Ugh. Another needless roadblock in the already painful experience of iOS development. Here's how I finally managed to fix this: Click on Edit to edit the bank information, then View/Edit details for the existing account. Without changing anything, click Next and Save. Then you gotta wait 24 hours, even though you didn't change anything hahaha!


Can I use Siri to remember a parking spot?

Source:

Yes, you can use Siri for this.

Simply say "Siri, remember where I parked my car."

Siri will drop a pin at the GPS location you're at.  You can use Maps to go back to this location.

As long as the parking location is marked, you can launch the stock Maps app on your iPhone and easily get walking directions to your parked car. This way, you’ll never have that lost look on your face ever again.

When you want to delete this parking spot, say "Siri, forget where I parked my car."  This will make Siri delete the pin.


How can I use Siri to send a pre-made SMS?

There are apps that do this, see Canned.

Really what you need (and I use) is a transit app of some kind. I like Transit.

I can't think of a way to get Siri to do this. One workaround is to make keyboard shortcuts so that you type "LGS" and iOS will autocorrect it to "123456".


Yosemite bluetooth audio is choppy/skips

It's an issue with the amount of power/bandwidth supplied to the BluetoothAudioAgent, the daemon in charge of streaming. Apparently most people have had success by entering the following command in terminal.app:

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" -int 40

Source: http://lifehacker.com/fix-your-bluetooth-audio-in-yosemite-with-this-terminal-1670380974

The source article lists Yosemite as the specific OS this applies to, but I know that this fix also works back to Mavericks and (possibly) Snow Leopard (untested).

I am having this exact issue at the moment and entered that command with non-noticeable results. I'm going to reboot the machine and see if that takes the new settings into account. But it seems like this command is the way that the wide majority of people have resolved this issue.

EDIT: Just rebooted, the audio quality is significantly better. No noticeable choppiness whatsoever (knock on wood). It appears that the command I posted above does seem to resolve the issue.

EDIT 2 (2015-8-24): The above command does help in many cases and produces noticeable quality improvements. Unfortunately, however, Yosemite is very moody with regard to bluetooth audio. The problem compounds itself when in proximity of other bluetooth devices. To expand on my previous answer above, I highly recommend entering the following additional commands to increase other bluetooth audio parameters:

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 48
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 40
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool Min (editable)" 40
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 58
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 58
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 48

EDIT 3 (2015-9-08): Alright. I'm sorry I keep updating this answer, but I keep finding more information about this issue (since improving bluetooth audio on Yosemite is a long-term effort, apparently). I've found several sources that cut straight to the mustard and set everything to 80 which appears to be the maximum allowable value for Bitpool settings. If the above settings don't work well enough for you, try the "All In™" approach.

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool Min (editable)" 80
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 80
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 80
defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 80

To see your current defaults:

defaults read com.apple.BluetoothAudioAgent

Edit 4 (2016-07-14): One more (hopefully last) edit. Make sure that you restart the bluetoothaudiod (or coreaudiod) service after making changes to these settings.

sudo killall bluetoothaudiod

Or, if you are on El Capitan:

sudo killall coreaudiod

Credit for this goes to the multiple wise nerds below who suggested it. (Thank you!)


Here are the specs for this mini according to Wikipedia. Note that this Mac (and most Macs I'm familiar with) has an audio line-in which is a high-level input, but no mic-in (low level). That means you'll need an external microphone amplifier between the mic and the line-in input. The USB mic is doing all of that for you - amplifying the mic and converting the audio signal to digital.


Airdrop already forms a mesh and doesn’t need WiFi networks to broadcast airdrop.

Existing  Apple hardware
builds a point to point mesh and you can airdrop across the mesh far larger distance than the range of your device alone.

So you don’t need to build anything but could have a functioning mesh.

There are improvements in hardware about to ship so we can revisit this answer when iOS 13 ships and matures and the new hardware ships and embargo expires for people that have seeded devices for review.


I use an app extension called ViewExif to look at the metadata.

https://apps.apple.com/us/app/viewexif/id945320815

If you have a date problem, those photos could be dated September 2021 and will be the newest until that date passes. That seems to be the easiest explanation. If not, then you’ll need to review the database - fix options with Apple or reset your library that stores the ordering of photos.
I would start with checking that the dates aren’t just not what you expect. It’s often a lot easier to change dates - look at this on the Mac Photos app if you can sync via iCloud or perhaps enable iCloud and use the web page to check as well.


Publish an Aperture smart album to Facebook

Select the photos in the Album, see if that works for you.


Second gen nano won't connect to computer

You seem to have done everything you can before resorting to really trying to restore it (which will wipe it). Bear in mind that an Apple store will probably wipe it or (if under warranty) replace it.


If you use a Magic Mouse, then yes!
Head over to System Preferences > Mouse. You will find an option there to set it to a two finger swipe to the left/right.

For other mice, ususally no. Some mice, like Logitech Master support all kinds of stuff though with the Logitech Options.
A workaround would be to set a Hot Corner (System Preferences > Mission Control > Hot Corners), then you don't need your keyboard, but it'll take longer.

My MacBook shows the screensaver seemingly forever! How do I tell it to just go blank after an hour or two without suspending the laptop?

Go into System Preferences and search for Energy Saver and (after you enter administrator privileges) you can change the settings to stop the display after some period of time.
Thanks @Steve Chambers for the detail - the Energy Saver settings aren't visible until you search for it.


How to find "intersection" of two strings?

In the absence of any other examples or formal criteria for how matching ought to be performed, I've just given an example here of the simplest way to obtain the difference between two strings:

    set A to "I like cherries, apples, berries"
    set B to "I like cherries, apples, berries, cookies"

    set the text item delimiters to {null, A}

    return text items of B as text --> ", cookies"

This works if one string is contained entirely within (i.e. is a substring of) the other, as was the case with your given strings.  If string A were to be `"But I like cherries, apples, berries" or "I like cherries, apples, berries.", the above method will not work.

It also won't work if string B contains the word "null" where string A does not.


What os is best for my MacBook Pro Retina 13-inch, Mid 2014?

"Best" is subjective, but given that your Mac supports macOS Mojave, that would be recommended as it's the most current version (unless you have a specific reason not to install it, like a mission-critical app that you know isn't compatible with it, though that's unlikely).

Additionally, Apple generally only releases security updates for the current version of macOS and the preceding major version. So, when the successor to macOS Mojave is released, presumably around a year from now, High Sierra will likely stop receiving security updates and you'll want to move to Mojave at that point anyway.


The right answer is probably this:

Distill sourcePath in_file destinationPath out_file adobePDFSettingsPath opt_file

And the paths have to be absolute, not relative.


How can I tell if a particular directory is connected to a remote machine?

The command df will include a list of all NFS shares, and their mount points. If a directory's path includes an NFS mount point, it stored on that machine.


Try resetting your router and add in the security features you use, one by one, until you see what 'breaks' push notifications.


Any fixes for persistent NO SOUND issue on 16" MBP (2020) OS 11.2…?

(Apologies if these seem redundant after all the support calls you’ve done...)

After erase & reinstalling, did you check speakers before installing your audio apps?
Does Safe Mode (Shift during boot) help?
What is the output of ioreg -r -c AppleHDAEngineInput ; ioreg -r -c AppleHDAEngineOutput?
What audio devices have you been attaching to your system? (Wondering if something might be overdriving the input preamp past an absolute maximum rating...)

UPDATE:

Yes I did check speakers before migrating. They worked.

This is a very important piece of data - it rules out hardware as being at fault. So now we’re solely focusing on what pieces of software in your migration caused this regression.
We can do this a few ways:

Create a new user account, reboot, log in with the new account first, and check your audio. This won’t help unless the cause is a user-specific misconfiguration.
You can try uninstalling one audio app at a time. This won’t help if the uninstaller of the offending software doesn’t do a thorough cleanup.
Reformat and reinstall the OS but do not migrate. Instead, install your audio software, one app at a time, until you see the failure. This is the most reliable (and most time-consuming) path towards root cause.

The ioreg command requires Xcode to be installed. If you don’t want to install it (understandably so), you can download IOJones and use its filter bar to search for AppleHDAEngineInput and AppleHDAEngineOutput.


Where does the Mac version of the iPhone Configuration Utility store its data?

~/Library/MobileDevice/Devices

The files appear to be stored as a plist with the device's UDID as the name.


Is there an iPhone 3GS app that stores incoming SMSes encrypted?

I don't think that's possible. You could send Encrypted SMS, though. So, in the end, you'll have them encrypted. Black SMS could do the trick. Extracted from Gizmodo's review:

  Here's how it works. When you download the Black SMS app, you attach a password to your message and then type whatever you'd like into the app. Once the message is complete, hit Send and the app will automatically open your SMS app. Paste the message and the recipient (and everyone else) will only see a black text bubble. SECRET AND ENCRYPTED BLACK TEXT BUBBLE, that is. The person on the receiving end then copies the black bubble and unlocks the message by pasting it into Black SMS with the password. If it sounds convoluted, well, it is. But hey, keeping secrets ain't easy.


2013 iMac 27" SSD Failure, Power Supply or Both?

Troubleshooting is often a process of elimination and requires time.

Considering all the steps you've already taken, the first thing I'd do next is to test your hardware with Apple Diagnostics.

Run Apple Diagnostics

Follow the steps below to run Apple Diagnostics:

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

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

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

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

Regardless, take a note of what happens and let me know how you went.


Apple Music Smart Playlist not syncing correctly with iPhone

I can confirm that somehow my library was the one out of sync. Songs that my computer thought were marked as liked were not marked as liked on my phone.


Not sure how to require password for keychain but here's how I handle sharing my computer:

My admin account is password protected and I have a "Guest" account setup that anyone can access without my intervention (just choose the account). It sets up a clean/empty environment every time. None of your data will be there and anything they create will not be stored.


Why is this folder 4.2mb? It only has a handful of relatively small text files in it!

Redirect Local Port through bridge to Internet Shared static IP

The proper command to redirect http traffic in your case is:

echo "rdr on $ext inet proto tcp from any to 10.0.0.36 port = 80 -> 192.168.2.34 port 80" | sudo pfctl -a com.apple/HTTP -f -

With $ext: the interface of the iMac connected to the router/modem (probably either en0 or en1). A redirect is done on the incoming interface and traffic! Therefore rdr on bridge100 ... doesn't make any sense here: you don't expect HTTP traffic with the destination 192.168.2.34 from the bridge100 to the network behind the very same bridge100.

The above command uses the temporary sub-anchor com.apple/HTTP and after a reboot it will be gone.

If you want to enable it permanently, create a separate anchor as outlined in this answer: pfctl - howto add an anchor and make it active / load it or here: Port Forwarding on Mac Pro with macOS Sierra.

A pass out route-to ... is only required if you want to redirect outgoing traffic from the iMac.

In theory an additional static route is required on the (TG852G) router/modem:

route to 192.168.2.0/24 via 10.0.0.36

Here (different router though) it worked without it.

Double-NAT solutions are generally not recommended in SOHO environments and I suggest to attach the Debian Linux server directly to one of the Ethernet ports of the router/modem or an interconnected switch.

iPad turned itself off and won't turn back on

That sounds like behavior consistent with a dead battery. How long did you leave it plugged in?

I'd plug it in and leave it charging for 15+ minutes, then hold the home button and power button simultaneously for 10 seconds to do a hard reset. If that doesn't work, it's off to the Apple Store to get a new one.


Where are the memory and kernel logs stored in macOS Catalina?

The easiest thing to do is to bring up Console, then for each log you are interested in, simply right-click and choose 'Reveal in Finder'. Your logs may vary. (If you don't know where Console is, simply search for it in Spotlight.)

Apple has a unified log system now, so you don’t want to just look at files like traditional unix logging. The log stats command will parse all available logs and let you know the current volume of information, how long it lives before being discarded, what severity of messages are so you can craft log show commands to dump specific entries of interest. Major events like a kernel panic do drop structured text files with details, but the logs are the best source.

https://developer.apple.com/documentation/kernel/debugging

For an intro to kernel debugging Apple does a great job. You can get Xcode for free and it has Instruments so you can inspect the system as it runs and also develop a kernel extension if you need to cause crashes or really get to low level.

Safari calls this the Web Inspector, so you’ll want to make your support clear by using the terms people will see. These developer tools are awesome for precisely what you seek.

Go to the settings app, Safari, Advanced.

As you can see this is a tethered operation where the data is shown on the desktop Safari. Most developers need to outsource this way and testing if you don’t find a Mac and iPad for testing and QA, but it’s entirely possible your users will help you to this level. It’s hard to be the developer and the tester since you know how you intended to use the app and can’t conceive of breaking it like someone who doesn’t know it uses the page in my experience. Also, timing delays and sketchy networks are hard to simulate in practice even when you enable the Network Link Conditioner on your simulator and devices for testing.

MBP Retina 13", very contrast images stays on the screen

Sounds like the Ghosting-Effece, even though I can't watch the Video because it says it´s private.
This effect can happen, when your screen shows the same image over an longer period. It is visible, when you switch to a blank image.

This problem is covered by your warranty from apple. The will most likely change the display for a new one.


'Mail can't connect to the account' keeps appearing

The quickest way to run through the potential problems is to follow these steps:

Check the keychain to find any entries that match your email accounts, then delete all of them. Reboot.
Try to connect again, entering your passwords again.  Check email again and see if the error reoccurs.
If the error happens again, delete your email accounts using the system preferences, reboot, and then add them back. Check email again.

If the error continues to occur after doing all that, you might think about taking your Mac into the Apple genius bar.


How can I create a Windows 7 USB from Mac OS to work on a PC?

Usually the person asking the question does not give enough information for a answer to be generated. So, I will try anyway.

Does, the PC have a working bootable DVD drive? If so, just use the OS X Disk Utility application to burn the iso to a DVD.

If your PC can boot from a flash drive, then you have two options. First, use some machine running windows to transfer the iso to the flash drive. Or, install windows 7 to a bootcamp partition on your Mac. Do not activate windows. You can use it for 30 days. Make the iso to flash drive transfer and install on the PC. Finally, remove the bootcamp partition. The last step is fairly easy, if your Mac is not using Core Storage.

The Microsoft software to transfer to the flash drive can be found at Windows USB/DVD Download Tool. The tool does not download software. Rather, the tool assumes you already have the iso and need to either burn a DVD or transfer to a flash drive.

If you edit and refine your question, I can update my answer to better fit your problem.


Songs stuck in Automatically Add To itunes folder

iTunes will put any songs that aren't compatible into a Not Added folder (underneath Automatically Add).  If your music wasn't compatible then you would find them in the Not Added folder.  So it seems that they are compatible, just not getting deleted.

I would check the permissions on these files and see if iTunes has permission to delete them.  Command-i on the files and folder concerned and ensure your use can read and write them.

Another solution is to open the Console.app application (found in the utility folder in Applications) and observe the output of that whilst iTunes is adding the music and see if there are any specific error messages that may point to why it isn't deleting the files.


MacBook Mac OS X Install DVD not loading on new hard drive

It seems like the install DVD is unreadable for some reason, either the disk is bad (DVDs are less durable than you might think), or the drive is bad (have you attempted to read any other disks lately?).

In any event, the easiest way to get around it is to boot off your old hard drive, and clone it to your new one. You'll need a USB external closure that can take a 2.5" SATA drive (they can typically be had for around $20 or $30). Put your old drive in that, plug it in, and hold down option as you boot. You'll get a selector screen, and  your old drive should be available to boot off of (it will likely be labelled Macintosh HD and have the orange external drive icon). Select that, and your Mac will boot just as it did previously. From here, there are a couple ways to get your new drive working.

Clone Your Old Drive

Unless you really want a fresh install for some reason, this is my recommended method. It will copy your entire system over to your new drive, so you'll get larger capacity, but without the hassle of re-installing everything.

To clone your drive, open up Disk Utility (found in Applications/Utilities, or just use Spotlight). In the right hand pane, you should see your old boot drive, and your new drive. Select your old drive, click the Restore tab, set Source to your old drive, and Destination to your new drive. Then click Restore. This will likely take a few hours, but once you're done, you should be able to restart and boot into your new internal drive.

Fresh Install from USB

If you want to do a fresh install, you can try reading the installation disk to a USB drive, which may be more reliable. You'll need a sufficiently large USB hard drive or memory stick (for 10.5, you may need 8 GB, but it's possible 4 GB will do).

To start, insert the installation DVD and check that you can read it. If you can, then you're good to go, otherwise you'll need to get another copy elsewhere, or a newer version of OS X (or you can try the clone method).

The procedure to copy the installation disk is the same as cloning the hard drives, you just switch the Source to the installation disk, and Destination to your USB drive. Once the copy is complete, reboot and hold option, and select your USB installation disk from the boot menu. You should then see the standard OS X installer and you can proceed as normal.


It's not an extension but the Quix bookmark has a handy host command that works with any browser - even mobile safari.

Dragging and dropping a file onto a Terminal window doesn’t escape the path under zsh 5.2

This behavior seems to be caused by zsh’s bracketed paste feature, which is on by default as of version 5.1. I found that if I added

unset zle_bracketed_paste

to my zshrc then dropping files onto Terminal works correctly with zsh 5.2.

(This blog post mentions bracketed-paste-magic, which seems like it could be used to support dropping files without turning off the entire bracketed paste feature. I think you would need to write code to make that happen, though; simply turning on bracketed-paste-magic didn’t fix my problem.)


4k screen can handle 60hz 90° rotated, but not in 0°

Your model MacBook Pro has an Intel Iris 5100 GPU that uses up to 1.5 GB of your main RAM as its graphics memory. It supports an HDMI-compatible device, including 4K, while using one Thunderbolt display, or supports two Thunderbolt displays.

In terms of external resolution, officially your Mac can display up to 2560x1600 pixels (using Thunderbolt) or up to 3840x2160 pixels at 30Hz or 4096x2160 pixels at 24Hz (using HDMI). This is why you're being limited to the choices you're getting.
