Reset volume control to 80% before shutdown

I have generated a script to run this for you. I have just tested it out on a computer running sierra, but it should be fine with your system. It consists of three files. All of these can be compiled using the setup script available for direct download from Github. When you download, just open it, and press the play button ► located at the top corner of the program.

Edit: I realized it is not downloading the files. Be sure to right click the Setup Download and save link as...

Then create something so people can get it easily; I used script editor and wrote a bit of AppleScript.


How to access internet on an Apple iBook G3 without Airport Card?

That is going to be tricky because any new usb wifi adapters are probably not going to have the driver support with the OS you are going to be using.
(If you are right about the model the maximum OS is 10.4.11.)

Amazon has original airport cards for sale and it looks like they aren't too expensive compared to newer adapters (~$20). That's the solution I'd use to get that computer online.


Can't access external SATA HDD via enclosure

Your "Update (GUESS):" is exactly correct macOS has no (native) ability to read/write filesystems common to Linux.
Heck it can only READ NTFS file systems without 3rd party software.
Also you cant just plug a bootable Linux installation (Or Windows, for that matter) into a Mac and expect it to just boot.
It is possible to work with and install both Windows and Linux on Apple hardware. Apple offers Boot Camp software that enables Windows 10 to be installed and run. But with Linux you will have to seek out how to install Linux on your Mac.
People here on AD may be able to help you with that. There are also lots of places online (mostly Linux-centric) that can help you install Linux on your Mac. But you cant just plug a Linux disk into your Mac and expect it to be bootable. Heck you need additional software just to read and write to the disk itself.


Of course there is a .plist file to (backup and) delete.

First of all close your Mac's Bluetooth
Open Finder
From toolbar select -> Go -> Go To Folder
Copy paste this path /Library/Preferences
Locate the file com.apple.Bluetooth.plist and rename it to
com.apple.BluetoothOLD.plist
Then do the step 3 again and
Copy paste this address ~/Library/Preferences/ByHost
Locate a file that starts with com.apple.Bluetooth... and rename
it.
Restart your Mac
Re-enable your Bluetooth and try again

Do you need to activate an iPhone 5s with the original carrier sim card before you can factory unlock it?

No. A factory unlock feeds the unlock status to the collective database that iTunes or the device polls when it does the activation.

Once the carrier has confirmed unlock status (or Apple feeds the unlock status to the carriers when you buy an iPhone factory unlocked out of the box) - the next restore event will alert you that the device is now unlocked.

In the case of a third party unlock - again, as long as the device sees that it is whitelisted when activation time happens, it doesn't matter who caused your phone's device ID to be cleared - just that it matches perfectly for the unlock to succeed.


Normally from the command line, you would use the diskutil command with the zeroDisk, randomDisk or secureErase options to securely wipe a disk. However, I would imagine this doesn't work on the disk you've just booted from. So I suspect you'll either have to find another Mac and connect yours in target disk mode via a Firewire cable, or physically remove the drive and connect it to another Mac using a disk caddy, to wipe it the way you wish.


Does PhotoStream sync to my Mac when iPhoto is not open?

Yes! A process called PhotoStreamAgent runs at login, and idles in the background, downloading new photos when they're uploaded to your Photo Stream.

There exist both /Applications/Aperture.app/Contents/Library/LoginItems/PhotoStreamAgent.app and /Applications/iPhoto.app/Contents/Library/LoginItems/PhotoStreamAgent.app, indicating that this background-downloading behavior works no matter which application you use to manage your photo library.

(And as Asmus points out, photos are stored in ~/Library/Application Support/iLifeAssetManagement/assets)


Sure. In Settings > General > Cellular > disable Cellular Data

This will restrict all data to Wi-Fi

Anyway to restore AFP as the default in 10.10?

You can still connect to AFP servers, you just need to make sure to include the afp:// at the beginning of the server name/IP. Unfortunately, I have not found a way to restore the default to AFP.


It looks like the "File" tab of the track info window has what you're looking for.


Have you tried deleting your iCloud account (which includes your iCloud account in the messages app) and re-adding it? There might be a stale config file somewhere that just needs to be re-created. Try either removing/re-adding your entire iCloud account or just unchecking/checking the "Messages" option under your iCloud account in System Preferences.


This is a progress bar under Downloads folder. It sometimes doesn't go away after completing the downloads. One solution for this is to enter this command in Terminal:

Macbook Pro freezes after I enter my password

ONE SOLUTION: if you've a spare OSX hard drive, re-fit it, and connect the SSD via SATA_USB cable. Boot holding alt, and select the SSD. It should be able to logon without issue. Next, shut the machine down, take out the old hard drive and refit the new, power her up, and the problem, for me at least, was solved.


OS X Server 10.7.4: VPN Authentication Failed for new users

Have you somehow set things up so you need to add each new user explicitly to a security group to allow VPN? Check the Access tab in server admin to ensure all users are allowed to authenticate for VPN connections.


You are set since Apple only uses the passphrase to help generate entropy on the actual key that's used to unlock the data. Apple wrote a very clear white paper that covers the protections and goes into some technical detail.

https://support.apple.com/guide/security/passcodes-and-passwords-sec20230a10d/1/web/1

If you set up a device with the same passcode 5 times in a row - none of the keys would be the same and no one could get at the data from the device even if you told them your passcode.
You are correct - they key is destroyed instantaneously and the data is cryptographically erased. You don't need any special tool to overwrite any of the data since it was previously encrypted and that encryption exists at rest. When you erase the device, the key that unlocks the data was destroyed and no passphrase will get that key back since it never left the Secure Enclave.

iCloud is more complicated, since your data lives in Apple’s servers and can be seen on the web, via API on official and unofficial apps, on Windows and on macOS and other devices in addition to your phone.
The encryption keys used to encrypt this data when it leaves your device are not the same keys as the ones used to lock the files at rest on the iPhone hardware.
So, you buy a new phone and take a picture of your pet. That pet photo is encrypted at rest with a key that’s entangled with your device passphrase, not actually encrypted with that passphrase alone.
Now - when you sign up for an AppleID or iCloud account - a different password generates a different set of key pairs both in the cloud and on device. Now things are much more complicated than just a device encrypting data at rest, since we have multiple key pairs and signing certificates and multiple computers involved just to get data to iCloud from your phone.
The process to sync the data to the cloud doesn’t need to know how to decrypt the data from storage to show it to you or send it to the cloud since iOS and iPhone hardware handle that encryption transparently to the apps. The running OS isn’t necessarily aware the data is encrypted like a fish doesn’t need to know it’s in the water to swim.
A different encryption is added before that data backs up or syncs to iCloud servers. In the case with the wiped device, when you sign in to iCloud, new key pairs are generated from that sign in event and used to decrypt the pet photo that comes down from the iCloud backup to your wiped phone (or new phone). The iCloud “app” decrypts the data and then the iOS stores it using the new local encryption key from the Secure Enclave (since your passphrase unlocked the device). Once sync is done and the file written to local storage, it is encrypted at rest with a different key than the key used to encrypt the data when it moved to cloud from old device and  back to the new device from the cloud.
To wrap up, the pet photo can be encrypted many times, using different keys based on where it’s heading. The same file gets transformed (in a reversible manner) so that when it’s decrypted, the data is the same file so it looks to us like your pet each time we look at that photo.
The hardware encryption is different than the software decryption and pulling this off in a way that people can use and not make mistakes in security is a very hard problem to solve.


Inserting a formula in Pages is not possible

Functions and formulas can only be inserted into table cells. So, you have to insert a table first. If needed, the table can be configured in the Table section of the Inspector to consist of only a single cell: 1 row, 1 column, 0 header. Also, the table can be set to have no border stroke/line.

If you are in a word processing document and want to position the table/formula freely on the page, you need to set the table to be a floating object (Inspector: Object Placement).

(This answer is based on Pages version 4.3, but might apply in principle to newer versions as well.)

Is it possible to "shut off" battery charging in OSX

I don't know I you already tried looking on Google, but this a problem multiple persons have tried to do.

There doesn't seems to be a Public API (yet ?) also no "private" API has been found yet.

Is the retina iMac's GPU powerful enough for its huge display?

This is the article you're looking for: The iMac and its 5K display... as a gaming machine? from ArsTechnica.

Nevertheless R9 M9290X is one of the most powerful mobile GPUs on the planet. That should be pretty powerful on development workflows (I'm a UNIX dev too and do development on GPU, mostly for crunching numbers though).

Edit: 280X was a typo, but I looked to the charts for desktop and mobile parts and 280X and M290X. Frequencies doesn't differ much, but memory bandwidth does. Also texture fill rate is 30% lower, but pixel rates are similar. Processing unit numbers were not directly available, but it looks 20% to 30% slower on real world, not 50%. This doesn't make it smoking hot, we're talking a lot of pixels here, but probably the card wont't be bogged down by the display.

What kind of development work you want to do? Level design? Hi-poly modeling? Engine development?


Time Machine: How can you confirm a backup? Can you just delete the backup and it will automatically redo it?

The first question, how can you be sure a backup has completed, is answered by checking the menubar Time Machine item. It will tell you the date of the last completed backup.

Secondly if you want to perform another complete Time Machine backup you can stop Time Machine, eject the Time Machine drive, plug in a fresh drive and re-enable Time Machine using that drive as the backup destination. A complete new backup will be performed.

You could also just delete everything on the original Time Machine drive but it is slightly more risky. If something bad happened before the new backup completed you would be without the backup you are not sure about and the new backup.


Keyboard backlight is on by default after High Sierra update

Using the built-in method

As per Apple’s Knowledge Base, Numbers supports absolute references:

  You can set row and column references in a formula to be absolute so that you can use the same formula elsewhere in your spreadsheet without the cell references changing, as they would otherwise.

To change your original formula to use absolute references, follow these steps:

Double-click on the original cell to go into edit mode.
For each reference, click on the triangle; then tick both boxes Preserve Row and Preserve Column.

Or, as an alternative to step 2, you can manually edit the reference to say e. g. $A$1 instead of A1.

The obvious drawbacks of this method are:

The method basically locks your formula in a mode that makes it hard to reuse the same formula in other places where you actually want flexible references.
If you you want to copy many different original formulas, you need to repeat the method over and over.

MacBook performance while on battery vs plugged in

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

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

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

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

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


Why are some family members missing in Screen Time setup?

Here is the support article on the topic: https://support.apple.com/en-us/HT208982

The part that stands out to me is this:

"To use Screen Time with Family Sharing, you need to be the family organizer or parent/guardian in your family group, on iOS 12. Your child must be under age 18, in your family group with their own Apple ID, and on iOS 12."

They likely don't meet one of these criteria.

How can I remap Caps lock to both Escape and Control?

Yes, using Karabiner (formerly KeyRemap4Macbook).

First, go into the Keyboard preference pane, click "Modifier Keys…", and change Caps Lock to Control. Then, go into Karabiner and search for this option:

  Control_L to Control_L
         (+ when you type Control_L only, send Escape)

Check that, and you're done. With Karabiner you can do lots more interesting things, like mapping your (now kind of useless) Escape key to a Hyper key with even more keybindings.


If I remove my apple ID account on my Iphone 4s, does it delete the data on iCloud on that device only?

Removing your Apple ID account from your iPhone should have no affect on the data stored in iCloud. You can safely sign out of iCloud and related services from your iPhone. In doing that, read the prompts to confirm that you are not as they look rather ominous at times, but should only be telling you that data will be removed from the phone.


Why was ⌘ used as the command key on Apple computers, why not the Apple logo?

From the Wikipedia entry on the Command Key:

  The "⌘" symbol (the "looped square") was chosen by Susan Kare after Steve Jobs decided that the use of the Apple logo in the menu system (where the keyboard shortcuts are displayed) would be an over-use of the logo.

It is also interesting that the ⌘ is not something Apple came up with. It is actually an ancient symbol called looped square.


How to add the Time Capsule to an existing network, in Ethernet?

Change order using the "Switch Keyboard" (Globe) key on iOS screen keyboard

It’s not actually random unless you’re experiencing a bug I haven’t seen. If you switch keyboards in fast succession, it cycles through the list in the same order as it’s presented when you hold. However, if you wait a second after switching the keyboard, the next time you press the globe button it goes BACK to the last keyboard you used (i.e. the last keyboard you kept open for a second or more). So if you don’t switch fast, you’ll end up switching between just two keyboards. I assume this is designed for bilingual people like me, but I agree that it’s confusing sometimes. One confusing consequence of this is that if I have keyboards A, B and C installed (ordered the same way in the list), I’m currently on B and before that I used A, then here’s what happens if I start quickly switching keyboards: it first goes to A because that’s what I last used, but then it SKIPS B and jumps to C, and from there starts cycling through the list. The full trajectory in this example ends up being B A C A B C A B C...

I would like an option to make the globe button cycle through only a subset of keyboards and make all other keyboards accessible only by holding.

Option 1 Reboot your phone

Restart your phone by holding the on/off button for up to 10 seconds then slide to turn off your phone. Then hold the on/off button till the apple logo appears.

Option 2 Sign out of Apple ID and Sign Back In

If just rebooting your iPhone doesn't fix the issue, you can try signing out of the Apple ID and then sign in back. Many times, this method works out well. To do this:

Option 3 Reset your Apple ID password

Sometimes, resetting the password might help fix this problem. To do this, launch Safari browser, and type this appleid.apple.com and hit enter.

Now, click on Forgot Apple ID or Password

Found Virus Bloodhound.PDF.20 on the time machine external drive, how to remove

When you delete a file, all the revisions go away, so you will want to first attack the file with the problem by deleting it.

If you can't delete it, move it to an external USB drive and then delete it.

At that point, you can let the scanner see if backup copies are still affected - but you are correct - you never want to use rm on backed up files. Delete them using the Time Machine interface to delete one file in all backups or one instance of one file or one backup instance. You can also use tmutil delete to remove snapshots from the backup drive.

How can I manually delete old backups to free space for Time Machine?

Does Mac have an display driver to go for higher resolution (than the current display)?

Apple, generally does not release drivers other than what ships with OS X. And video card manufacturers generally do not release drivers for their devices installed in a Mac under OS X unless it is a PCI card or some such that has a chipset not specifically supported by OS X.

I suppose the Hackintosh community may have some drivers that do that but I would tend to think that what you are looking for is not available under Mac OS


Cannot change anything inside a folder, however it's not Locked and I have all the rights

UPDATE 2 (now I got it):
The culprit is the ACLs. Apparently Time Machine uses them, and copying via Finder preserves ACLs.
They are easy to remove recursively from folders where you know they are not needed:
sudo chmod -R -N ~/Pictures for example will drop all ACL rules in ~/Pictures and everything inside.
Source/more info: https://backdrift.org/fixing-mac-osx-file-permissions-and-acls-from-the-command-line
older unsuccessful attempts:
After some more desperate searching and brainstorming, I came up with one workaround:
1: Install coreutils from Homebrew (if not already done so)
2: gcp -dRl <broken_folder> <temporary_folder> — this will "copy" it with hardlinks instead of actual copying while not preserving permissions and any other "invisible" things which could be broken, so it's fast and almost zero damage regardless of file sizes
3: Test if permissions in temporary folder are OK "in practice"
4: sudo rm -rf <broken_folder> && mv <temporary_folder> <broken_folder> — remove bad one and put fixed one in its place
based on this answer and GNU cp manual.
UPDATE:
In newer versions of macOS even this doesn't work. Looks like they are actively trying to make me switch to another OS.


I have run into the same issue.

I have the developer preview of Safari 6 (Beta) installed on Lion and now that ML is out, I can no longer get the uninstaller from Apple's Developer Connection Website.  Like you said, all the links are stale and point me in the direction of the Safari Website with no download links.

All direct links to the Safari 6 Beta Uninstaller, like this one:

Uninstaller

Do not work and say that your session has expired.

Unfortunately, at the moment, I have not been able to find a copy of that uninstaller or any older version of Safari to reinstall.  Usually though, the beta version is just superseded by newer versions that will be coming out eventually or they will release an update for beta users, or reissue links for the uninstaller.  Unless you can find the uninstaller somewhere, I would suggest doing nothing. Do not uninstall safari yourself or delete things, this might cause issues that could just as easily be fixed with patience. It suck to mess things up and make things worse when technically the Safari 6 Beta works just like Safari 6 for Lion.

I know it isn't the solution you were looking for, but everything will work itself out, either with Apple fixing things, or an update that just installs the newer version for you.

I hope that it helps.


How to set positioning/filling of desktop background image with AppleScript

According to

'AppleScriptEditor' > File > Open Dictionary >
   Finder > Legacy Suite > Application > desktop picture

all you can do is set the picture.

There are references to messing about with the .plist file, but the internet (and Apple) are silent on an Applescript-approved route.

This plist is empty for me in Sierra:  ~/Library/Preferences/com.apple.desktop.plist so I imagine Apple have hidden what used to be there inside one of their even less well documented databases.

International Phonetic Alphabet (IPA) dictionary guide in OS7

As far as I know, there is no way change the dictionary to IPA or download custom dictionaries to iOS (save for jailbreaking it). However...

This isn't a complete solution, but if you hit "Manage" and download "Oxford Dictionary of English" it will give you an English dictionary with IPA pronunciation. The only caveat is that it will be British English pronunciation.

Which depending on your use may or may not be useful since it will depend heavily on the particular word defined and your own dialect. For instance, the word "solution" in American English is usually pronounced something like suh-loo-shun while British English would pronounce it more like sull-yoo-shun (pardon my bad almost-diacritics), which can throw you off if you are using it to learn or reinforce already learnt IPA.


It's possible that one of you is using the phone number to initiate a message, and the other is using an email address.  Starting from a blank slate, send a message, and have Niels reply, do you then have a single session, or 2?  If this is behaving oddly, try initiating the chat with both email and phone numbers, and see what happens.

Your recent contacts will likely show both messages from e-mail and phone number.  You might think that the iPhone should match and merge both conversations but in fact they remain separate for good reason.  Imagine you have an iPhone and an iPad, messages to the phone number only go to the phone, messages to the email go to both. It's a case of knowing how to reply. If it merged the 2, which would it choose to reply to?  It would have to choose the email address, as it's portable, the phone number isn't.  Any attempt to merge could leave one of your devices only getting half the replies, or the inability to reply if replying to an iPad from an iPhone that has decided to use the phone number as the primary contact choice.


3rd Party Mac Developer Application: DEVELOPER NAME: no identity found

‘Developer name’ is your personal name or company name, depending on whether you have a personal or organisation developer program membership respectively. You're also missing the Team ID from the string, which in the end should look something like this:

  3rd Party Mac Developer Application: John Appleseed (XXXXXXXXXX)

You can find your developer name and Team ID in Keychain Access. Search for "developer" and find one of your certificates. The green section is your developer name, and the blue section is your Team ID.


What's a good way to wipe a hard drive for resale?

"Quick charging" has to do with the current that the charger supplies.  It's not a mode you can select.  Laptops don't have the ability to quick charge as a typical USB port only provides 5V at 500mA max.  You need at least 2.4A to quick charge (12W).

You can try doing a hard reset of the phone, but if the problem persists, it's definitely a failing/failed battery and it will need to be replaced.


Actually there is another step in here...

iOS > Settings > General > VPN > ~YourVPN_Profile (Click the 'i' icon) > Connect On Demand (turn toggle switch to 'off') = sorted!

NB. Use the VPN option under Settings > General... Not the 'VPN' switch under Settings!

Unknown caller generally means their number (caller id) is private


Try these steps :

Click the Smart Playlist.
Setup the sort order and arrange as desired.
Right-click the Smart Playlist and choose Copy to Play Order.
Sync the device with iTunes.

Is there a native way to keep a window always on top in Snow Leopard?

There is no "native" way to do this. Your existing solution, Afloat, is the only one I've ever heard of (and works quite well).


How to switch to a tab in mobile Safari without it reloading?

The bottleneck is the available free memory (RAM) on the iPhone.

If Safari starts running out of memory it will flush the contents of older tabs meaning they have to reload when you switch back to them.

If you have too many tabs open, or you simply have multiple tabs that each have a large web page in them, Safari will reload when you switch back to another tab. There’s no fixed limit; it depends on the combined size of the HTML + all assets each web page you have open and on the total number of tabs you have open.

As the available RAM in new iPhone models increases, this will become less and less of a problem.


USERS AND GROUPS advanced options cannot access

Changing an account name in the Users & Groups preferences pane is (as you've found out the hard way) not recommended unless there already exists on the system another  account with Admin level permissions so the resulting issues can be fixed.  You might be able to resolve this by activating the root account following instructions given here:
https://support.apple.com/en-us/HT204012, then editing the sudoers file using vi in terminal to add your current username as shown below.
(from my sudoers file:)
User privilege specification
root    ALL=(ALL) ALL
%admin  ALL=(ALL) ALL
[new username][doublespace here]ALL=(ALL) ALL

Save the edited sudoers file then restart and see if using the new username account to login & make any other fixes to permissions that might be necessary.


Spotlight can do this.  You just need to hover your mouse over the "Look Up" entry:


How do I use the keypad on my iPhone to dismiss autocorrect?

If you update to iOS 5, you can go into Settings > General > Keyboard and add "Sydney Hunters" to automatically be replaced with "Sydney gumtree".


Bose QuietComfort 20 not working after Yosemite upgrade

Seems that the Audio Output selector was "Parallels Access Audio".  When I used parallels access apparently the default output was changed, and not reverted.


Font Book does in fact have a view that displays all glyphs provided by a font — just select Preview - Repertoire on the menu bar:

Why does find-certificates have some missing?

This is due to a combination of two factors:

Specifying the SystemRootCertificates.keychain is necessary, otherwise a personal keychain is used.
openssl will not parse a stream of multiple keys into a stream of text.

The following runs openssl once per certificate and accomplishes what I was looking for:

security find-certificate -a -p /System/Library/Keychains/SystemRootCertificates.keychain \
| awk '/-----BEGIN CERTIFICATE-----/ { cert = "" } \
       { cert = cert $0 "\n" } \
       /-----END CERTIFICATE-----/ { \
           openssl = "openssl x509 -text"; \
           print cert | openssl; \
           close(openssl) \
       }'


Connect Macbook Air with external monitor

A quick google showed me that this MacBook supports:

  Dual display and video mirroring: Simultaneously supports full native
  resolution on the built-in display and up to 2560 by 1600 pixels on an
  external display, both at millions of colors

So, yes it looks like the Macbook will support the full resolution of your monitor.


Bad sort order in file picker, correct in Finder

Finder and the file dialogs have had two different sorting modes (sort by and arrange by) since 10.7. In the first screenshot, the arrange by mode is probably set to date created or date last opened. Try changing it to none instead:

The menu shown above changes the arrange by mode and clicking one of the header columns changes the sort by mode.


AutoFill data is unrelated to your physical location as it's just stored addresses, phone numbers, etc.

You can adjust or remove AutoFill data under Settings > Safari > AutoFill. Generally it's from a contact card that you have selected as yourself.


I think you'll get the answer in the iPhone 4 teardown that the guys at iFixit did sometime ago:

http://www.ifixit.com/Teardown/iPhone-4-Teardown/3130/1

You will be able to see there what components are inside the iPhone 4, but I'd guess all the video compression/decompression is processed by the A4 processor (an ARM Cortex A8 core variant).

Using Profile Manager or OS X Server to distribute apps to a group of Macs

I have a similar setup as you are describing and use Apple's Remote Desktop (ARD) application for tasks like installing and updating apps.
For apps that are .app files, you can use the "copy" command and move them directly to the /Applications folder (or other location like /Library/Quicktime for codecs as an example).
If the installer is a .pkg file, you can use the "install" command in ARD to have it install properly on the remote machine.
However, for apps that have their own installer application (I'm looking at you Adobe, and your Flash updates!) you are not able to use ARD to help with this.
Now, although this is not "automatic", you CAN schedule the time of these installs. This way you can do your updating on off hours.
I hope this info is helpful.


Software Recommendation for iOS app to wake Ubuntu computer with MAC Address

Either one of these apps should work:

iNet WOL ($1.99)

I use this app, and it works very well.

Mocha WOL (free)

I haven't tried this app, but it looks like it should work just fine.


How do I link slides in different keynote 6.5 presentations?

Unfortunately, Apple removed that feature (along with many others) when they released Keynote 6.  It's unclear why, but some people attribute it to a security concern?  Not sure if they ever intend to reinstate it.

Your best bet is to downgrade back, if possible.  I think the last version that had that feature was 5.3.


Why does my hard disk (in MBP optical caddy) keep unmounting when writing?

I found out that this particular model (late 2011 Macbook Pro) has an issue with the optical drive SATA: It can only operate reliably in 3Gb/s mode, but reports that it supports 6Gb.

The drive I was using supported both speeds, and is supposed to automatically switch to 3Gb when necessary. But because the bus reports that it's compatible with 6Gb, it stays in 6Gb mode. This works fine most of the time as the actual transfer speed doesn't exceed 3Gb. But when it does, the bus misbehaves and all sorts of problems occur.

After much frustration (and several different drives) I settled on putting a 3Gb (not 6/3) drive in that bay instead. Works great now. Incidentally, the other SATA drive bay supports 6Gb just fine.


How do I make the Microsoft RDP client for Mac play nice with Windows 10?

I believe the bitmap caching was an option with earlier versions of RDC on the Mac; but according to this link, it is no longer possible to change this.

Duplicate IPs

Are there conflicting IPs on the network?

A possible cause I've seen given these symptoms is duplicate IPs. Duplicate IPs on either the Windows 10 box or the Mac can cause this issue.

Try refresh the IP (assuming DHCP) on one or both sides and monitor the stability.


No, this will not harm your device in any way.

Airplane mode is a software thing, not hardware. Therefor, It cannot ruin your device.

Are the keystrokes under guest Ubuntu via Virtualbox supposed to be the same in a Ubuntu?

The multitouch events are handled exclusively by OS X and not passed through to the guest OS. Basically, the focus that keyboard and pointer have passes faithfully to the VM. Focus for the trackpad is filtered and not passed.


After a lot of messing about I managed to get this working in two ways.

The first is by using the Retina Display Manager I found on reddit.
This gives a menu with all the available display modes, but try the second method first.
Screenshot 1 (Warning, large file)
The second I found after using Retina Display Manager, to my surprise the Displays pane in System Preferences was reporting it was running in 720p mode.
This mode is actually 1280x720 HiDPI (2560x1440).
Screenshot 2 (Warning, large file)

Yay!

I was going to embed screenshots of these new menus, but they are now insanely huge due to HiDPI mode, so I just linked to them instead.


How does iOS detect the version of an installed app?

It’s the Info.plist, heavily cached. Changing this on a jailbroken device is a common way to prevent App Store updates for an app.


iPod Classic can't be seen by iTunes 12.7 on Windows 10

I spoke with Apple Support. The iPod Classic is no longer supported by the software, period. Backwards compatibility is not considered and old versions of iTunes are not provided by Apple. In fact, the support personnel are forbidden to provide an older version. They suggest buying a new iPod.


Restore Shell configuration and packages

To get the styling and some other things back simply extract Backups.backupd/$COMPUTERNAME/latest/$SYSTEMVOLUME/Users/$USER/Library/Preferences/com.apple.Terminal.plist from the backup and copy it to /Users/$USER/Library/Preferences/
To get the shell config copy Backups.backupd/$COMPUTERNAME/latest/$SYSTEMVOLUME/Users/$USER/.bash_profile (and/or .profile/.bashrc) to /Users/$USER/. If you prefered another command interpreter (e.g. zsh) in the past, choose the respective files. Same with history files/folders like .bash_history and .bash_sessions.
I don't advise to copy anything from Backups.backupd/$COMPUTERNAME/latest/$SYSTEMVOLUME/usr/local/bin to get your brew packages back. Instead check Backups.backupd/$COMPUTERNAME/latest/$SYSTEMVOLUME/usr/local/var/homebrew/linked and Backups.backupd/$COMPUTERNAME/latest/$SYSTEMVOLUME/usr/local/opt and install the listed packages one by one with brew. The keg-only dependencies will be installed automatically.

Entering brew bundle dump in Terminal before formatting the drive and moving the result to a save place, would have helped to restore your old brew enviroment on your current system.
Check Backups.backupd/$COMPUTERNAME/latest/$SYSTEMVOLUME/usr/local, .../bin and .../sbin for other binaries installed independently.

with

$COMPUTERNAME: the computer name before formatting
$SYSTEMVOLUME: the name of the system drive before formatting
$USER: your user name before formatting

Almost all files and folders are invisible because they start with a dot or they are flagged invisible. So either use the AppleShowAllFiles YES feature or a decent file browser (like Path Finder).


How to run programs from an external hard drive on MacBook Pro?

You just need to copy the application to the external drive. Mac apps can actually run from anywhere, it is merely convention to keep them in the /Applications folder.

Of course all the preferences will still be in your home Library folder but the app will be on the external drive.


Podcasts is part of iOS, not on the App Store, therefore you can't review it on the App Store.

Gray exclamation mark in Photos (Sierra) after importing raw pictures from my camera

The problem is your camera is too new! Apple Photos does not yet support RAW files from the  Fujifilm X-T2. Apple should release an update that will add this support, but I could not tell you when that might happen. For the full list of supported camera RAW formats, see this site.


Remove "Creative Cloud Files" from Finder sidebar?

This is how you show / hide certain icons of the Finder Sidebar:

Try a right-click on the folder, then 'Remove from Sidebar'.

1) Go to 'Finder', then open 'Preferences' from the menu bar

2) Navigate to the 'Sidebar' tab

3) Uncheck the appropriate icon(s) as required. Then close.
I believe that apps like CCleaner can clean up these "ghost" directories too. However, based on your question, these steps should do the job. Let me know how you get on.


Can I use a Carbon Copy Cloner with a source disk that's larger than the target disk?

Yes - CCC copies by file and so will manage.

This was my original setup and worked. It is now more complex as I now have more data on the source than can fit on the target, I manage this by choosing the files in CCC and deselecting ~/Downloads /tmp etc.


Sharing Google Calendar with wife so she can see it on iPhone

How to delete the Java installed shown in the "System Preferences" dialog?

You can uninstall Java from the command line by using the rm command, this is aimed for advanced users who understand the ramifications of using rm with superuser privileges. This is not for novice users, using the command line requires precise syntax and failure to use proper syntax may result in erroneous commands or unintended data loss.
One by one, execute each of the following commands individually:
sudo rm -rf "/Library/Internet Plug-Ins/JavaAppletPlugin.plugin"

sudo rm -rf "/Library/PreferencePanes/JavaControlPanel.prefPane"

sudo rm -rf "~/Library/Application Support/Java"

Observations: This requires authenticating with sudo. Be certain you have the syntax 100% correct, if you are not sure if the syntax is correct do not execute the commands, and instead you’d likely want to use the Finder based approach of uninstalling java instead.


The memory pressure (yellow part at the bottom of the first screenshot) so I recommend upping your ram to at least 8 gigs of RAM (or even 16 if you can afford it). To see what kind of RAM you need, see HT1423 .


First make sure that the Silent switch is turned on. Check on the left side of the iphone and make sure that the silent switch does not show red.

If it is not in silent mode, change try changing the ringtone and see if it works. If not reset the iphone from settings->general->reset->reset all settings.

If both methods does not work contact an Apple Genius.


Issue about the external display on macOS Mojave

Best guess, you have unchecked 'Displays have separate Spaces' in System prefs> Mission Control...

Manually update tz (time zone) database in Mac OS X?

Working Quick Look Plugins For Mountain Lion

If you install Xcode, most source code files are shown (albeit without color) natively. The "without a file extension" makes things interesting since unless the file is typed, quicklook (and the spotlight importer responsible for determining what type of file each one actually is) has less context to decide how to classify a blank README file.

Have a look at the qlcolorcode plug in for colored syntax quick look and QLStephen for README and other ASCII plain text files.


Getting coordinates for frequent locations?

There is nothing directly on the iOS device to provide the coordinates. Through the iOS developer sdk you can access the CLVisit class which has the following properties:

coordinate- which will give you the geographic coordinates
horizontalAccuracy- gives the horizontal accuracy of the above coordinates
arrivalDate- date arrived to location
departureDate- date departed location

There is also a CLFloor class which has the following property

level- which will give you a value for the floor. 0 bring ground floor, 2 being 2 floors above the ground floor, etc.


Accessing photos on iPhone iCloud backup

If you have a copy of the backup, there are a couple of ways to get these back.

Free
http://www.itunesextractor.com/extract-photos-from-iphone-backup.html
Paid

I would make a backup of your file, then try the free one first and if that doesn't work try the paid version if these photos are important.

Hope one of these will work!


How can I prevent Music app from starting automatically randomly?

I have had this experience and I discovered that my finger was lightly brushing the "Play" button on the MacBook Pro's Touchbar. If the current app has no hook for that button, it seems that macOS now choses to launch the Music app.

The solution should be to run launchctl unload -w /System/Library/LaunchAgents/com.apple.rcd.plist. See this howtogeek for details.


How to mass remove known Wi-Fi Preferred Networks in OS X?

Note that this will also clear the same settings from any linked iDevice.


How can I setup my printer to print in black and white as default?

@ughoavgfhw's answer is incomplete. Some applications (like Google Chrome) will not use the last used preset, but will use the default preset. In order to have such applications adhere to your default settings, you have to interact with the underlying printing system CUPS. These steps will get you there:

Run cupsctl WebInterface=yes using the Terminal application (only required once).
Browse to http://localhost:631/
Go to Printers
Select printer to modify
Choose Set Default Options from the second drop-down
Under Basic set Output color to Black (this step might be different for your printer)
Hit Set Default Options and presto!


How to delete music album from iPhone but not from any other devices nor from iCloud

1. Via iTunes

When you sync your iPhone with your main iTunes on a desktop computer, you can simply untick the undesired song/album/artist and hit sync, and it will disappear from your iPhone.

Image from HowToISolve

In this example, ticking Ke$ha will include it, and unticking will exclude it from your phone iTunes library.

2. Directly on your iPhone

Go to Settings > General > iPhone Storage > Music > Edit to delete artists, or ... > Music > Song > Edit to delete songs locally on your iPhone.

Image from my iPhone

Be aware that those files will be included should you sync your phone again.


Mac book: Is battery cycle low means mac book still can be used at long time ?

I can speak from experience that the battery from by 2011 MBP 13' died (like only 10% of designed capacity left) after 56 cycles. It met a precipitous decline after a certain point. You may want you weigh your risk on the cost of replacing the battery.


Send Wired Keyboard Keystrokes Through Bluetooth

Type2Phone - $9.99

Any keystrokes you type while Type2Phone is focused will be sent over Bluetooth. You can Command+Tab to and from it as well.


You may have overdrawn/gone into your overdraft. If your card does not have an overdraft facility, be careful, the amount of money you overdrew can get charged horrifically (at least it does here in the UK).

Not sure what Apple policies are or the time they allow to fully pay if off if they haven't collected the full money though.

Hope this helps!


Can a jailbroken iPhone and a non-jailbroken iPod Touch operate on the same machine/itunes

Sure, it'll be fine.  I did that for a while after I got my iPad and still had my jailbroken iPhone 3G.

Jailbreaking, at least at its basic level, doesn't mess with most of the basic functions of the device such as syncing.  All bets are off if you install some JB app that is specifically meant to alter some part of the sync process, but even then it's very unlikely it will cause trouble of the iPod.


iCloud control panel in Windows is missing Mail, Contacts, Calendars, and Tasks tab

Although I don't really know what the original problem was, I did find a workaround.

When trying to connect iCloud to Outlook I was using my PST file from my old machine, and the iCloud option to sync "Mail, Contacts, Calendar & Tasks" was missing.

I then deleted MS Office and reinstalled.  Now, before copying over my old PST file I tried to connect iCloud with the new, empty, PST file.... and it was now successful.  I was able to "see" my iCloud Contacts and Calendar.  So, far, so good...
I then copied over the old PST file, made it the default pst file, and deleted the "new, empty" pst file. Went into Outlook and everything was there... my mail, iCloud calendar, and iCloud Contacts.  Success.

Now, why did this work???  The ONLY thing I could think of was that, somehow, iCloud knew my old pst file was already connected to iCloud so it didn't offer the option to connect to outlook.  As soon as I used a "new" pst file, iCloud showed me the option to connect to outlook.  Anyway, that's my theory.  Anybody have any other ideas about what might be happening?

Macbook Air 2015 High Sierra cannot merge free space partitions

The simple fix is:

Back everything up (apps and files and settings and possibly keychain passwords if you don’t have them written down / recorded elsewhere)
Boot to internet recovery
Erase and start with one partition

Using the command line to merging containers requires you to clearly understand quite a few items and processes and concepts and one mistake ruins the data. It’s like several passes on a trapeze at the circus, without a net. It takes months of experience to make it look effortless and years of experience to always succeed.

What is the benefit of purchasing a Mac formatted External Hard Drive?

It's probably no different hardware-wise, just already formatted for the Mac. There's a whole pile of people who still think Macs need special everything, so the companies take advantage of that to fleece them out of an extra £20.

In general, you don't need special Mac-only hardware stuff anymore. Hard drives, RAM, peripherals, etc. are all fairly generally universally compatible; even the stuff that's generally seen as "Mac" (i.e., FireWire and now Thunderbolt) is Windows- and Linux-compatible and will generally work fine.

EDIT: I guess I can think of one good reason to buy a pre-formatted "Mac" drive: if the user is not someone who is comfortable formatting disks. On the other hand, Disk Utility is sufficiently straightforward I've walked my parents through formatting drives a couple of times over the phone, so I wouldn't waste the money.


For audiobooks, I prefer AudioBook Builder, which takes a bunch of mp3 files and merges them into the audiobook format instead. Advantages of this format is chaptering and the ability to remember where you left off listening.


Configure zabbix_agent on macOS High Sierra

Checking brew installer or configure/make messages often help to determine where files and folders are stored or how and where to configure services or apps:

Example output after installing the required dependencies:

...
==> Installing zabbix --without-server-proxy
==> Downloading https://downloads.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.4.7/zabbix-3.4.7.tar.gz
==> Downloading from https://10gbps-io.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.4.7/zabbix-3.4.7.tar.gz
######################################################################## 100.0%
==> ./configure --prefix=/usr/local/Cellar/zabbix/3.4.7 --sysconfdir=/usr/local/etc/zabbix --enable-agent --with-iconv=/Applications/
==> make install
  /usr/local/Cellar/zabbix/3.4.7: 13 files, 1.4MB, built in 1 minute 31 seconds

One ./configure flag of zabbix is --sysconfdir=/usr/local/etc/zabbix.

Consequently the configuration file(s) and folders (i.e. zabbix_agentd.conf.d) can be found here:

/usr/local/etc/zabbix/

Additional zabbix* man files can be found here:

/usr/local/share/man/man1/
/usr/local/share/man/man8/

Additional steps to perform:

Add /usr/local/sbin to your path. Some brew-installed binaries are installed to this folder (e.g. dnsmasq or zabbix)
Get the zabbix agent to launch at boot time with a launch daemon/agent. I haven't found one accompanying the brew-installed zabbix.

Several can be found at github though:

com.zabbix.zabbix_agentd.plist (the config dir in the plist has to be modified though).
zabbix_agentd_osx_installer (either the UserName/GroupName keys have to removed or a User and Group each with the name zabbix have to be added as special user/group with dscl or the Users & Groups prefpane though or the daemon will fail)

The older zabbix 2.2.5 installer uses the following postinstall script to add a zabbix user & group/modify files and folders:

#!/usr/bin/env bash

#To create a group:
sudo dscl /Local/Default -create /Groups/zabbix
sudo dscl /Local/Default -create /Groups/zabbix PrimaryGroupID 113
sudo dscl /Local/Default -create /Groups/zabbix Password \*

#To create a user:
sudo dscl /Local/Default -create /Users/zabbix
sudo dscl /Local/Default -create /Users/zabbix UniqueID 113
sudo dscl /Local/Default -create /Users/zabbix UserShell /usr/bin/false
sudo dscl /Local/Default -create /Users/zabbix RealName 'Zabbix user'
sudo dscl /Local/Default -create /Users/zabbix NFSHomeDirectory /var/empty
sudo dscl /Local/Default -create /Users/zabbix PrimaryGroupID 113
sudo dscl /Local/Default -create /Users/zabbix Password \*

#Create needed directories
sudo mkdir -p /var/run/zabbix-agent
sudo mkdir -p /var/log/zabbix-agent
sudo mkdir -p /usr/local/bin
sudo mkdir -p /usr/local/sbin
sudo mkdir -p /usr/local/etc/zabbix

sudo chown -Rf zabbix:zabbix /var/run/zabbix-agent
sudo chown -Rf zabbix:zabbix /var/log/zabbix-agent

sudo chown root:wheel /Library/LaunchDaemons/com.zabbix.zabbix_agentd.plist
sudo chown root:wheel /usr/local/etc/zabbix/zabbix_agentd.conf
sudo chown root:wheel /usr/local/etc/zabbix_agentd.conf

sudo chown -Rf root:wheel /usr/local/sbin
sudo chown -Rf root:wheel /usr/local/bin
sudo chmod -Rf 755 /usr/local/bin
sudo chmod -Rf 755 /usr/local/sbin

sudo chmod 755 /usr/local/etc/zabbix
#sudo kill -9 `ps aux | grep zabbix_agentd | cut -f11 -d" "`
#sudo kill -9 `ps -aef | grep zabbix_agentd | grep -v grep | awk '{print $2}'`
#sudo rm -Rf /tmp/zabbix*

It's not recommended to execute all these steps but the script may serve as an example how to get it to work. Some have already been executed by installing zabbix with brew (e.g. some sudo mkdir ... commands). Some aren't necessary (e.g. some sudo chown root:wheel ... commands) or will even break brew (e.g. sudo chown -Rf root:wheel /usr/local/bin). If you choose to create a zabbix user/group, make sure that the user can read, write and execute files in the /usr/local/etc|sbin|bin branches.

Move the edited plist file to /Library/LaunchDaemons/ and load it - after editing the zabbix config file - with:

sudo launchctl load /Library/LaunchDaemons/com.zabbix.zabbix_agentd.plist


How to get Apple Watch 2 to calculate VO2 Max data?

I went for a 2:30:00 run yesterday with my iPhone (6s) in my bag and my watch running strava. VO2max was recorded once per hour in three hours (10-11/11-12/12-13). I’ve tried to get VO2max off of shorter runs (5k-10k) on the same route without my phone but no data. I will now have to test longer runs with just watch and shorter ones with phone to get a definitive answer. Hope this is helpful.

How do I Export Apple mail database to Outlook 2016 for Mac?

Apple Mail archives its database in .mbox format and outlook for mac can only import either .pst or .olm format files. It definitely cannot import emails exported from apple mail. If you have an Imap enabled account then you can directly sign in to the outlook mac, it might take a while depending on your email database size, your files will start uploading.

You can take alternatives as well, where some application are available that can convert the file format. Here is one I found online: http://mailexporterpro.com/

I hope this suits your needs.

I think we're facing similar issues. There's no real fix, if you want to run with those settings, but at least you know what is going on.

If you're using the dark appearance (Settings -> General) and enable reduced transparency (Settings -> Accessibility -> Display) you end up in a situation like this.


Thanks for the Console log:

I see two item making problems with the User Interface (UI) in (WindowServer)

One is the VLC.app and the second one is the "Transmit application"

I know what is VLC app, so just disable (remove) it to test. (then download updated version)

Second one "Transmit" you know what it supposed to do but it is making problems. See if there is an update  or disable it.


This MAC address keeps showing up -- A8:BE:27:AC:10:37 -- it’s not mine

If you use a MAC address lookup tool on the internet it does show up as an Apple device, so there is that.

Some routers allow you to ban devices, if yours does, ban that device and see if anyone in your household complains.

Some routers only allow you to set a whitelist (only allow the devices I specify on), in that case you have to add the MAC addresses of everything you want on your network and everything else is effectively banned.

Again if someone complains you know what that device is.


Yes & No.

It's free for recent Apple hardware purchasers - though irritatingly I can get it for free on my iPhone but not my Mac...

However...
You can download the iWork 09 trial for free & App Store will then update it to the current version.

I'm not sure whether it's strictly legal or not, but I'm sure they could have shut it down years ago if they really didn't like it.

See How do I convert old Pages documents to Pages '13?

Extract :

Go to Softpedia

Click on External Mirror 1

This will download iWork09Trial.

Open the dmg & run the installer.

Run any of the 3 apps, then check App Store for updates.

Edit : After the release of Yosemite, you can no longer update to the latest versions of these if you are still on Mavericks or below. They are now considered "Incompatible Updates". Same for Aperture, iMovie & iPhoto


Try some basic steps:

First of all backup all data of your iPad and restore the iPad from the backup. If it still happens, restore the iPad to factory settings.

If that doesn't work, try downgrading to 9.3.2 (you can still do it) by downloading the IPSW file from ipsw.me and download the iOS 9.3.2 IPSW file for your iPad model.

If problem continues, you may have to take it to the Apple Store and let them service your iPad because it might be a hardware issue.


Is there an app to disable everything but GPS on iPhone?

If jailbroken, SBSettings allows one to turn off everything: Data, Wifi, Bluetooth, 3G, Edge, Phone, SSH, etc. but leave GPS enabled.

If not jailbroken, Settings > General > Network lets you turn off WiFi, 3G, BlueTooth, and Data, which leaves GPS, Edge, and Phone. Turn brightness all the way down. This ought to extend battery life quite a bit.


Will Lion X be downloadable for everyone?

No, the update will not be free (though it is yet unclear what the price will be, possibilities ranging from $29 to $129), and will only be free for those who purchase computers within 2 weeks of the update coming out (this is usually the time window for the free upgrades that Apple offers) in the summer. If you've purchased your computer recently, sorry, but you'll have to pay for it.


Can a MacBook's Thunderbolt port be used as an HDMI "in" to view a feed/signal from a video camera?

No, not directly.  You can buy any number of HDMI capture hardware that connect via thunderbolt or FireWire and use a thunderbolt FireWire adapter.

How can I change OS X Double-Click on Title Bar to be like Windows?

Update July 2020 - macOs Catalina 10.15:

Choose Apple menu  > System Preferences, then click Dock.
Select check box Double-click a window’s title bar to zoom

3. Double click on window's title bar to maximise the window.

zoom: Expands a window to fill the space between the Dock and >the menu bar.
If the Dock is along the side of the screen, the window >fills the >space below the menu bar and to the side of the Dock.

macOs versions upto High Siera:
Its old question , but still if it helps anyone.
You need following 2 in order to maximise your window when clicked on title bar:

Go to Apple icon > System Preferences > Dock >
Select "Double-click a window's title bar to" "Zoom"

Shift + Double click on title bar to maximise the window.

Cheers

'which openssl' returns nothing when trying to upgrade OpenSSL

This command should show you where any openssl binaries may be located on your system:

locate openssl | grep bin/openssl

For homebrew, make sure you have /usr/local/bin and /usr/local/sbin in your $PATH. You can check your current path setting by issuing echo $PATH.


The partition table of disk0 is not ruined at all - all changes made are rather unintended.

All partitions and volumes (EFI, Common, macOS and Extra) are properly marked and a diskutil verifyVolume disk0sYwill probably exit with no error.

A ruined partition table would miss the secondary partition header and table, or the primary and secondary header/table are different, or the CRC-32 checksums of the header and partition table entries are invalid.

Your partition table looks like this:

    start      size index contents
        0         1       PMBR
        1         1       Pri GPT header
        2        32       Pri GPT table
       34         6
       40    409600     1 GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B

The first partition with a size of 209.7 MB - the standard EFI partition - is followed by unallocated disk space with a size of 46.94 GB.

The second partition is a standard HFS+ partition with a size of 86.37 GB followed by unallocated disk space with a (standard) size of 134.2 MB.

The third is a APFS container partition with a size of 90.87 GB. The fourth partition is another standard HFS+ partition with a size of 26.35 GB.

A default SSD partition layout would probably look like this after installing High Sierra (APFS) and a BOOTCAMP partition though:

     start      size index contents
         0         1       PMBR
         1         1       Pri GPT header
         2        32       Pri GPT table

X+Y+671784       ...     ...

The second unallocated disk space (262144 blocks) may be smaller or larger.

Consequently it depends on the size of your old macOS partition if parts of it were overwritten or not.

If X was equal to or smaller than 91672536 (blocks) your old macOS partition can be recovered completely.
If X was larger than 91672536 (blocks) and smaller than 260358640 (=91672536+168686104) (blocks) parts of your old macOS container partition were overwritten by creating the Common volume. Creating a new empty volume usually requires about 120 MB - 500 MB to write some file system metadata. Depending on the size of the APFS system/preboot/recovery volume parts of them may have been overwritten.

If the first block of your vanished APFS container (including your old macOS APFS system volume) wasn't overwritten you can detect its former size:

Boot to an external drive with macOS installed
Open Terminal and get the usual disk related details (below I assume the internal SSD has the disk identifier disk0):

diskutil list
sudo gpt -r show disk0

Unmount the SSD

diskutil umountDisk disk0

dd/hexdump block 409640:

sudo dd if=/dev/disk0 bs=512 skip=409640 count=1 | hexdump

which will yield something like this (example only!):

the third line is the important one:

29 ea 22 01 00 00 00 00 APFS container size in APFS blocks: 19065385 (=152523080 512-blocks)

After re-arranging the Bytes 29 ea 22 01 00 00 00 00 > 00 00 00 00 29 ea 22 01 > 00 00 00 00 01 22 ea 29, you can get the decimal value here:

The size of the old APFS container in 512(blocks) is then APFS block size x container size in APFS blocks. In the example this is 4096/512 * 19065385 = 152523080 blocks.
depending of the former size remove the 2th partition:

diskutil umountDisk disk0
sudo gpt remove -i 2 /dev/disk0

restore the old partition (here with the size of the example: 152523080 blocks(512) - don't use this one accidentally!):

diskutil umountDisk disk0
sudo gpt add -i 2 -b 409640 -s 152523080 -t 7C3457EF-0000-11AA-AA11-00306543ECAC /dev/disk0

check the APFS container

diskutil verifyVolume disk0s2

check the APFS system volume

diskutil list #get the device identifier of the APFS system volume and use it below (probably disk2s2)
diskutil verifyVolume diskXsY

Macbook often goes to max CPU and then hangs there

I had the exact same issue on my MBP 2017 15", using it with external screens and Mojave 10.14.6. Turned out to be a bug with NightShift (documented here). Turning off NightShift solved the problem.

Maybe this will also help you.


How to edit m4b audiobook metadata in Catalina?

Thank you everyone!


Can I script checking for password date changes from ARD?

I found the info, but the data format is unnecessarily complex. At least in Mavericks (and I suspect several previous versions), it's in a property list, which is wrapped up inside another property list (the passwordpolicyoptions property in /var/db/dslocal/nodes/Default/users/root.plist). Theoretically, you should extract that property to a file, then use something like /usr/libexec/PlistBuddy to get the passwordLastSetTime property from it... but hacking it with sed is much easier:

dscl . -read /Users/root PasswordPolicyOptions | sed -n '/passwordLastSetTime/{n;s@.*<date>\(.*\)</date>@\1@p;}'

This command must be run as root; interactively you'd use sudo, but if you're running it with ARD, just use "Send UNIX Command", and set "Run command as: User: root".


Can't Open Applications on Old Mac (OS X 10.4)

You can look up the specs on a particular Mac at Everymac.com, which would tell you whether you can add RAM, and what the maximum is. The Everymac site allows you to look up a Mac by serial number, which you can get from the Apple Menu, About This Mac, then  "More Info...", which opens System Profiler. It will also tell you the Machine Model, which might be something like "PowerBook6,8", which can also be used to look up a given Mac's specs.

If you go down to "Memory" in the System Profiler list it will tell you the type of memory installed.

You also might want to watch Activity Monitor as you open the program to see what it does with memory usage. Can you open the program without loading the project you are working on, to make sure the program is OK, then try to open the project?


How to install the OS with a new Hard drive?

You can create your own recovery disk with Recovery Disk Assistant and a blank USB drive that is at least 1 GB. Alternatively, your Mac can boot into OS X Internet Recovery mode in which it downloads an image from Apple's servers, and it can do this with a damaged recovery partition or even a blank hard drive -- it's built into the firmware of the system. To access it, boot up while holding Command + R. You can do this over a wireless network that is either unprotected or WPA-secured, or you can use an Ethernet connection. In both cases, your system will need to download OS X from Apple (the recovery partition does not contain a full OS X.)


It happened that the last update (OS X 10.9 (13A603)) solved this issue on my Macbook Pro 13' of mid 2010.

Mail.app keeps asking for Google password

If you have several devices accessing your Google account via IMAP you can reach the limit of connections Google permits. The limit is 15 connections per account, however, bear in mind that each client can open multiple connections. In my experience the limit is easily reached with 3 devices. I have read that the Thunderbird email client has a setting to specify how many connections it can open, Mail and Outlook do not have this option.

Your Mail client should prompt you with a message along the lines of "Too many simultaneous connections." However I believe on iOS devices and Apple Mail you may see a more generic error.

The workaround for this issue is to log in to the GMail web interface, scroll to the bottom of the page and click the 'Details' link. From the popup window click 'Sign out all other sessions'

Is there a way to show an icon in the status bar if iPad is muted?

iOS does not have an option for this, nor does apple approve apps which alter the status bar.  If you want this function you will have to jailbreak your iOS device and install a third party status monitor.  As pointed out in another answer, LockInfo does this.  SBSettings used to, but no longer does.  If you're running an iOS 4.x device, OpenNotifier might be useful as it does this as well as give you pull-down notifications similar to android and iOS 5.

If you're developing for this device, however, you can add this function yourself.  As a developer you can run custom code without jailbreaking the device - you just can't submit that code to the app store.

The trick, then, is going to be finding example code for this feature.  I expect someone in the jailbreaking community will have some info on what the code needs to do, and if you're lucky you'll find an open source project for it.  Then you can compile and sign it yourself, and as long as you keep your ad-hoc license current and recompile/re-sign it yearly, you can use it on your personal devices.

I think a lot of developers overlook the fact that they can run any code they want on their own devices without jailbreaking.  They can also distribute such apps in a limited manner to their friends using adhoc distribution as well.

It looks like OpenNotifier is open source, and has the functionality you need:

https://github.com/n00neimp0rtant/OpenNotifier

I don't know much about the status of the project, but it might be usable for you as a developer to bring this functionality to your devices.

What is the best method to apply a screen protector to a touchscreen?

First I make sure the screen is completely clean using a micro-fiber cloth, then I use a credit card with the cloth wrapped around to press the screen protector tightly as soon as it touches the screen.

The trick is to press, making a forward/backward movement, the protector against the screen as soon as it touches it, removing any bubbles in the process. So don't try to put the protector all at once.


Failure to install mysql on macOS Mojave

MySQL 8 makes big changes compared with previous version 5.7. Downgrading directly to the lower version 5.7 from 8.x won't work.

Solution:

Uninstall all MySQLs you've installed.
Since you're setting up a new machine, there's no existing database. Just clean up the broken database.

# brew-installed mysql
rm -rf /usr/local/var/mysql

# db from the official installed
# should be located at /usr/local/mysql (I'm not very sure)
ls -ald /usr/local/*mysql*
# then delete any folders listed by ls

You'd better remove the conf file /usr/local/etc/my.cnf as well.
Reinstall MySQL.


Go to System Preferences → Mission Control and uncheck Automatically rearrange spaces based on most recent use.


"File" NOT "App"... can't be opened because it is from an unidentified developer

I have two guesses:

It is an application masked as an mp3 file. Yes, you should not open it.
Mac OS X gives warnings "blabla downloaded from internet" for anything, not just apps downoaded from Internet. If you are sure the file is fine, play it back.

By the way, mp3 files must be able to play back by just quick previewing them (Space bar).


Mac stuck after trying to install updates, startup disk missing

The generic advice when a Mac can't start is to boot to recovery HD (internet, local or external as is most convenient for you) and run Disk Utility to check for connection, decide to make a backup of critical files if needed, then attempt a First Aid - repair pass.

https://support.apple.com/en-us/HT204156

Assuming the First Aid works, you should be able to boot again or reinstall the OS from recovery. If not, you need to seek hardware repair, data recovery or try an erase install.

The reinstall instructions below get you to Disk Utility so you can look there and proceed.

iTunes suddenly decided my mp3s are mpga movies that iTunes won't play. What happened?

Here's a workaround, which also makes no sense: as explained at this link, switch iTunes to run in 32 bit mode via the Info box.

This doesn't explain parts 1-4, but it does at least make the tracks playable. I'd still love to know what is actually going on.

Also, you can enable the "Kind" column and sort by it to discover which of your tracks have mysteriously been converted to Quicktime Movies.

How to split screen in TotalTerminal to end up with two terminals?

The way I achieve this is ensuring that tmux is installed on the machine I'm SSHing to.

Once you've issues tmux you can do ctrl-b % to split the screen vertically, or ctrl-b " to split it horizontally.

This will give you two sessions within the same terminal window, and can also be persistent across logins. This may not be exactly what you want though.

How to bridge vboxnet with Wi-Fi on OS X 10.10 "Yosemite"

VirtualBox and OS X provide several (no-NAT) methods to connect your VM:

1. The VirtualBox "Bridged Adapter":

First remove bridge1 in Terminal and use a "Bridged Adapter" instead of vboxnet0 in your VM. Go to the Network settings of the respective VM -> Adapter1 -> attached to: and change the type from whatever it is now to "Bridged Adapter" then choose your Wi-Fi interface:

The VM's en0 attached to the bridged adapter has to be configured with a unique IP in the same network range as the hosts interface IP.

Example:

My hosts en1 config: network: 192.168.1.0/24 IP: 192.168.1.2 gateway: 192.168.1.1
The VM's eth0 config: network: 192.168.1.0/24 IP: a free and unique IP-address in the range 192.168.1.3-192.168.1.254 gateway: 192.168.1.1

If you want to make the VM accessible to other computers in the WAN (internet) (e.g. a web-server) you have to forward the respective ports in the router to the VM's IP. The VM can be accessed by all other computers in the same network (192.168.1.0/24) in your LAN directly.

Finally it looks like this:

WAN <---> Router/Switch (& port fw to VM) <----> Mac <-------> VM
           192.168.1.1                      192.168.1.2   192.168.1.130
                ¦
                ¦
             other Mac(s)
           192.168.1.3|4|5...

2. The OS X bridge

I assume en1 is your Wi-Fi interface and eth0 is the first adapter in your (Linux-)VM. Check this with ifconfig on your VM-host. Please adapt the commands and change the interfaces below if necessary.

If you don't want to use "Bridged Adapter" but vboxnet0 do the following after starting VirtualBox:

Attach the VM adapter 1 to the "Host-only Adapter" and the "Name" vboxnet0.

On the host in Terminal enter:

sudo sysctl -w net.inet.ip.forwarding=1
sudo ifconfig bridge1 destroy #if bridge1 still exists
sudo ifconfig en1 down
sudo ifconfig vboxnet0 down
sudo ifconfig bridge1 create
sudo ifconfig bridge1 addm vboxnet0 addm en1
sudo ifconfig bridge1 192.168.1.2 netmask 255.255.255.0 up

In the VM (Linux) you have to configure an IP-address and a default route:

sudo ipconfig eth0 192.168.56.101 netmask 255.255.255.0 arp
sudo route add default gw 192.168.56.1

A configured "Network Manager" might interfere with those settings.

On the various Macs in your network you have to configure an additional static route:

sudo route -n add -net 192.168.56.0/24 192.168.1.2

On the router your have to forward ports to the VM and add a static route to 192.168.56.0/24 to make the VM accessible to other computers in the WAN (internet).

Finally it looks like this:

WAN <---> Router/Switch (& port fw to VM & static route to 192.168.56.0/24) <-----> Mac <----------------------> VM
           192.168.1.1                                                    192.168.1.2|192.168.56.1   192.168.56.101 (& default gw or static route to 192.168.1.0/24)
                ¦
                ¦
             other Mac(s)
           192.168.1.3|4|5... (& static route to 192.168.56.0/24)

The bridge and the various routes (except those on the router and the default gateway of the VM) don't survive a reboot.

To roll-back all changes:

To remove bridge1 on the host do the following:

sudo ifconfig bridge1 down
sudo ifconfig bridge1 deletem en1 deletem vboxnet0
sudo ifconfig bridge1 destroy

To disable forwarding on the host do the following:

sudo sysctl -w net.inet.ip.forwarding=0

To remove static routes on the Mac enter:

sudo route -n delete -net 192.168.56.0/24 192.168.1.2

Remove the static route on the Router.

As a result one might say it's much easier and much more comfortable to use method 1.


Time Machine backup to remote disk at night

To schedule your Mac to boot or wake up at a particular time every day, you can use the Terminal command pmset. In your case, the appropriate pmset command would be:

pmset repeat wakeorpoweron MTWRFSU 02:58:00

To schedule Time Machine backups on crucial servers after hours, I've relied on TimeMachineEditor. With this app, you can set backups in a very granular fashion.


What are the major advantages of the Late 2013 rMBP 15'' high-end model over custom configurations of its low-end counterpart?

A custom-built ME293 model with a 2.3 GHz CPU, 16 GB of RAM and 512 GB of SSD, although costing the same as the stock ME294, is not the same hardware because it's missing the Nvidia GPU. I speak from experience as I have one of these (Intel GPU only), with the 2.6 GHz CPU upgrade. Other than that I'm fairly sure they're identical.


Macbook Air crashes/restarts when something doing something heavy on it

Welcome to Ask Different!

I don't think it's enough details to answer for sure. The best would probably be to go to an Apple Store ask them to run there diagnostic tool on your computer.

What it looks like is that the computer gets too hot and enter in safe mode leading to the shut down to avoid the melting down of the processor.

That said maybe there is too much dust and your computer is actually too hot, or maybe one of the sensor is wrong and then it will show on the diagnostic tool.

You can also use a software like iStat Menu or HWSensors to read yourself the sensors and try to spot something wrong.


How to prevent iPhone 12 Pro from overheating?

If you have a cover or case for your phone, you should try removing them as they tend to hold in the heat. Keep you phone out of the sun and use it in a cool area. You can also turn your screen brightness down some and kill background apps you are not using. If that doesn't help turn off Location Sevices on your phone. Do this by going to settings-privacy-location services off.
These and other options are described here and here.


I typically use the App Store app to download BBEdit since it runs for free and has all the things you would want including line numbers. If you are familiar with VSCode, that’s a solid option too, but it is not a native app like BBEdit and TextEdit are.
I’m fairly sure there is no line number function in TextEdit.

Sudden shut-downs I would always attribute to heat - dust/fluff collecting in the fans & heat sink fins. It takes more than a quick run-round with a duster or a can of air to properly clean out the fins; it needs splitting open & getting in properly - even so far as replacing the heat sink paste.
It's not a job for a beginner, especially on a laptop, but the guys at the Genius bar ought to be able to steer you in the right direction.


How to delete all voice memos stored on iphone in one go?

If you don't use iCloud to sync your voice memos you can delete the Voice Memo app (same as any other app deletion) and redownload it from the App Store. This will delete any Voice Memos stored only on the phone.


Mac 10.13, 10.14 where are the hash passwords located?

10.14 protects these files with SIP, so even root cannot access the files without using the directory services command.  If you need to get this information deactivate SIP.  Remember to reactivate SIP after you are finished.  If you attempt to access using the directory services call shown above then you do not need to deactivate SIP.


iPhone 7 is frozen and I can't turn it off

I would repeat this process two times 5 minutes apart and one last time 15 minutes later and them move on to the more painful remedies.

https://support.apple.com/en-us/HT201559
https://support.apple.com/en-us/HT201412 (try the force reset only unless you want to escalate to restores)

Once you’ve exhaused asking nicely and not so nicely for the device to redstart, you have options that require a computer or more time:

Wait for the battery to die / exhaust itself. Then plug it in and see if it works or needs to be restored.
Call the phone / text the phone / try to get something to work that you can accept from the lock screen to know it’s still basically functioning. Sometimes after answering the call, you can then get to the unlocked device - other times, you’re back at the lock screen.
Connect to iTunes and restore the device.


How do I temporarily disable applications from starting up at login?

Hold the shift key as the user log in process starts.

You need to hop on the shift key quickly if you enter a password right after pressing return, get on the shift.

If your account logs in automatically, look to get on the shift when you see the gray screen with the dark grey apple logo. Next comes the blue screen and then the graphical user log in portion. If you hold the shift too early (before the Apple logo) you will have a safe boot(not what you want)

A safe boot has much more temporarily disabled than just the user log in items.

See the Apple knowledge base article for more information about items that open automatically at start up and how the shift key trick works.


That could be a lot of things. It could be the system, it could be the hard drive, it could be a drive cable...it could be lots of things. It sounds like it's a drive problem.

The following links are "how-to" links from the guys that make Scannerz. One is how to use activity monitor to try and isolate processes that are using too much CPU/Memory etc and the other is about bad hard drives. The Activity Monitor post says it's about Mountain Lion, and clearly some of the topics are Mountain Lion specific, but in general it shows how to use Activity Monitor and some tricks I never new about. Here are the links:

http://www.scsc-online.com/Activity%20Monitor.html

http://www.scsc-online.com/Bad%20Hard%20Drive%20Signs%20and%20Symptoms.html

Although you have an SSD, I was surprised to see a post on MacRumors where someone used Scannerz on a system that was having problems that sounded similar to yours. Scannerz found bad cells in the SSD. The owner is replacing the SSD under warranty. He also found his cable was bad. Talk about bad luck!

If I had a link to it, I'd post it but I don't. You could go to MacRumors and search their forums for "Scannerz" and I would think you would find it. Like some of the other posters in that thread, I though SSDs were supposed to automatically correct bad blocks, but apparently that applies only to sectors that have depleted their write ability.

Hope this helps.


why use yosemite bootable usb installer when you can use recovery HD for clean install?

A bootable drive saves the entire OS X installer locally. If your current reinstall were happening from a bootable drive, the "downloading Yosemite" step would be nonexistent because everything's already there.

As in, you're wrong. The specific benefit of a bootable drive is the ability to reinstall OS X without needing to download it on the spot. (Of course, first you needed to have downloaded the OS X installer and run through the bootable drive-making procedure at some point beforehand, but the point is that once you've done that one download, you've got it for whenever you need it.)


The current low level Mac Mini with an upgrade to 4GB memory is probably the best bang for your buck. That's what I have except with 8GB; got my memory from Amazon for $130, cheaper than Apple memory. It's a very capable machine. If you use a lot of programs simultaneously, the standard 2GB is kinda cramped, but 4GB would do fine; it just seemed like a good deal for 8GB and I use more than your average number of apps simultaneously and lots of Safari tabs.

The new MacMini is much nicer than the 2009's. I know this because I had one before this one; with 2GB of course :).

You're gonna love OS X by the way. Don't be surprised if you ditch Windows in a year.

About your specific questions:

Any current Mac has an Intel CPU. Apple switched from PowerPC back in 2006 and yes you need one, but you don't want a computer that old anyway!
Just about any keyboard or mouse will work fine with OS X. If you are using some kind of fancy mouse or keyboard, then you'll probably will need some third party software to get all those custom parts working, but all the standard parts will work; left click, right click, scroll wheel, cursor control etc. There is a chance however that there is no OS X equivalent of the third party software you may be using.
Finally, Macs work with standard monitors and even regular modern TV's with DVI, VGA, HDMI inputs (virtually all of them do). The most you'll ever need is a common adapter found at Best Buy, Apple Store etc.


Windows using Bootcamp won't read any USB memory sticks

I managed to finally fix this.  All I did was reformat the External HD as the "MS-DOS(FAT)" filesystem through Disk Utility.

I'm assuming it was an issue with the "ExFAT" filesystem, although I could plug it into 2 other Windows laptops in my house with ExFAT.


How to create a mp3-clip from an existing mp3?

Open it in QuickTime Player, click Edit → Trim… (⌘T), drag the yellow handles to truncate it to the snippet you want, and export the result.

Note that it will export in AAC (.m4a) format, so if you need MP3, you'll need to convert it afterwards.


A self assigned IP address suggests that your system did not receive an IP address from a DHCP or similar protocol.  As Otto Andy Heiskanen mentions, restarting the DHCP server (by rebooting the router) can solve this issue often.  However you mention your Linux environment does get an IP address, which could point at a different cause.  You also mention that you are not allowed to access the router's settings: are you able to physically access it to pull the power plug?

If you can't access it physically, I recommend you compare the settings in the Linux environment with the settings in OS X.  Is the Linux environment getting an assigned IP address, or is it a fixed IP address?  Perhaps your linux environment is using a MAC address that is different from your physical MAC address?  Maybe there is some newly configured MAC address filtering enabled on the router?
