LAPACK, BLAS, ATLAS on Mac book pro 2017, Mojave

For clarity, the original post is asking about mathematical (linear algebra) libraries (usually in FORTRAN or C) that are included with macOS Mojave, specifically LAPACK (Linear Algebra PACKage), BLAS (Basic Linear Algebra Subprograms), and ATLAS (Automatically Tuned Linear Algebra Software). These libraries are included in the Accelerate framework, documentation can be found here: Apple BLAS documentation

On my machine, these are located here: /System/Library/Frameworks/Accelerate.Framework

These libraries are also included in many FORTRAN compiler packages vis-à-vis Intel iFort and the like. They are also available here: LAPACK and BLAS and ATLAS

The OP is also curious about which libraries are linked in python and how to change them. I am amending my answer to provide context on this as it is relevant to those in the Apple community who use their machines for computational intensive tasks.

To determine which libraries numpy is linked, open up terminal and type:

python
import numpy as np
np.__config__.show()

This will yield how numpy is linked. On my machine this is:

mkl_info:
    libraries = ['mkl_rt', 'pthread']
    library_dirs = ['/Users/wjid/anaconda3/lib']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['/Users/wjid/anaconda3/include']
blas_mkl_info:
    libraries = ['mkl_rt', 'pthread']
    library_dirs = ['/Users/wjid/anaconda3/lib']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['/Users/wjid/anaconda3/include']
blas_opt_info:
    libraries = ['mkl_rt', 'pthread']
    library_dirs = ['/Users/wjid/anaconda3/lib']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['/Users/wjid/anaconda3/include']
lapack_mkl_info:
    libraries = ['mkl_rt', 'pthread']
    library_dirs = ['/Users/wjid/anaconda3/lib']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['/Users/wjid/anaconda3/include']
lapack_opt_info:
    libraries = ['mkl_rt', 'pthread']
    library_dirs = ['/Users/wjid/anaconda3/lib']
    define_macros = [('SCIPY_MKL_H', None), ('HAVE_CBLAS', None)]
    include_dirs = ['/Users/wjid/anaconda3/include']

If you are concerned about computational efficiency and are using an Intel processor, you'll probably want to use the MKL libraries that ship with Anaconda or Miniconda (what I am using). If you want something else, you will likely have to build from source.


How to delete (tmutil delete) all old backups from TimeMachine - keep only current full backup

#!/bin/bash
latest=$(sudo tmutil latestbackup)
sudo tmutil listbackups | while read backup; do
    if [[ "$backup" != "$latest" ]]; then
        echo sudo tmutil delete "$backup"
    fi
done

Remove the echo once you are sure that the output is correct.

How to change how long notifications stay on a Mac?

I was able to get this to work as of Catalina (10.15.2)

First, you need to specify -int before the number of seconds parameter:

defaults write com.apple.notificationcenterui bannerTime -int 2

You then need to restart the NotificationCenter process by signing out/rebooting or running:

killall NotificationCenter


What is the recommended partition scheme for mac os x?

As mentioned by the other comments, Apple's default partition scheme is to have everything on ONE partition.  While not recommended (potentially due to not being easy to do), it is possible to move a home folder to a different partition.

Here is how:

Create a partition to use for the home folder (Disk Utility is the built-in choice to do so)
enable the root user

open System Preferences
click on Users & Groups
click on Login Options
open the padlock on the lower left-hand corner
click on "Join" next to Network Account Server
click on "Directory Utility"
from the menu "Edit" click "Enable Root Account" and supply a password for that account

log out of the current to-be-moved user
choose "Other" at the login screen
type in root into the username field and supply the password you just gave it
navigate to your other partition and create a base home folder (to use Apple's naming convention, create a folder named "Users")
navigate to the system's Users folder and copy the user's home folder over to the other partition.
open System Preferences > Users & Groups
open the padlock on the lower left-hand corner
right-click (or Ctrl+click) the user you want to move and choose "Advanced Options"
for the field "Home directory", either click the button "Choose" (if it is there) and select the new path or type in the new path.

If you type it in, the path starts with /Volumes/<volume_name>
Important: Use the proper capitalization as depicted on your system or you may run into problems
Do NOT change anything else on that form (e.g. user ID) or you may end up not be able to log in or use the system with the other user

click on "OK"
restart your computer holding down the Alt key until you see boot options on the screen
choose the recovery option (e.g. "Recovery HD-10.10")
choose the language when asked
from the menu "Utilities" choose Terminal
type in resetpassword and hit Enter
choose the hard drive you normally use to boot from
choose your user
Click on "Reset" at the bottom of that window to reset permissions
reboot your system normally and try to log in to your user

If this is working for you as expected, here is the clean-up:

remove your user account folder from the system drive (to save disk space on your system drive)
disable the root user again to improve system security (follow the same steps as outlined above and choose "Disable Root User") this time

In case it is not working (though I would understand that it will), you can use root to log in and move the home directory back to where it was using System Preferences > Users & Groups > Advanced Options (right-click on that user).

I hope this guide helps.


Is there a reader for iPhone or iPad that supports many formats?

Book Reader Pro is what you are looking for. The ebook file format support is outstanding. The supported file formats are  PDF/EPUB/CHM/DJVU/FB2/CBZ and XPS.

Stanza would be another good choice but I'm not sure about it file format support.


Unfortunately, I think each VPN client will be picky about this in its own way.  Since the network is dropping from underneath the SSH connection, you will have three scenarios that could cause it to "hang", or just drop (that I can think of).

Data is flowing back and forth, and the connection is gone.
You get a new IP address when reconnecting.
Timeout/Alive conditions trigger before you reconnect.

2 Suggestions...

Use screen (you said you don't want to do this, I know, but it really is the most robust solution.  There are scripts out there that can greatly enhance/automate the reconnection process).
Compare your SSH configurations.  Usually stored in /etc/ssh_config or similiar.

BTW -- I don't think you should need to close windows, just do "~ ." (tilde dot).  Tilde is used to control the ssh session.  See the manpage for more details.

How to stop assignment of numbers to hostnames?

This seems like a problem with your router. Try forcing your hostname with scutil:

scutil --set HostName yourhostname

Why the number?

The bracketed numbers appear because the same Bonjour/ZeroConf name is being used multiple times on the network. If Bonjour detects a duplicate name, a number is appended to ensure uniqueness.

This does not indicate a serious problem. Resetting network caches and devices should help clear out the now superseded name.

Apple's Bonjour Frequently Asked Questions page discusses this behaviour:

  12. What should happen when two devices on the network both use the same service name?

  In the rare case where a name collision occurs, your device should add
  a digit to the end of the name, for example:

  "Apple Mac mini (2)"


How do I enable "Network Trash" on a file server?

The Synology NAS supports a Network Recycle bin, but only for SMB volumes. Therefore if you want to make use of it from your Mac, you need to access the share via SMB and not AFP. This can be enabled from the Control Panel under Win/Mac/NFS.

The Synology by itself fully supports Time Machine, and can act as a Time Capsule. Most of the documentation on the Internet mention the Network Trash and Time Capsule option in the same place, but as an Windows/Mac comparison type description. The manual for DSM does not mention Network Trash for Mac either, only for Samba.

I am not entirely sure where you read that the Synology supports this feature for OSX, since I couldn't find any reference to it in the way you described.

OSX, unlike the previous OS 9, does not support a Network Trash of any kind, and I am not aware of any plans to bring this feature to OSX. Therefore it also can't be activated from the OS layer.

I suspect the naming was changed from Network Trash to CIFS Recycle Bin in the new DSM by Synology because of the confusion it has caused.


Use Disk Utility.

You can use the New Image button in the toolbar to make a new disk image.

If you can be a little more specific as to what you want to do, I can be more specific as to how you'd use Disk Utility to do it.


How to disable creation of spaces on macbook?

If there’s no window on a space, do the three finger swipe up gesture or F3 and you can hover on the top left corner of the thumbnail and a cross appears. Just delete the space.

If there is some window on some space, you can drag it and bring to the other space to make the previous one empty. In the same mission control state, hold the window in one space and drag it to destination thumbnail.

If it is made by a full screen app, as Tetsujin says, it cannot be deleted and when app returns to its original space, the other one is automatically deleted.


search for file extensions with ~ in finder

In Finder hit Cmd+F to open the Spotlight interface (without requiring a string to search for).
Hit the search parameter dropdown (by default "Kind"), select Name.
Select 'matches' in next dropdown.
Type tif~ in the text box.

You could select Kind → Other and insert tif~, but does not work that way.

Additionally,  you could search for it on the Terminal type the following in your home directory:

find . -name "*.tif~"

How to get back Chinese Speech after upgrading to Mojave?

There seems to be some issue with the upgrade to Mojave.  I then first removed all the speeches in Chinese inside of System Preferences, and then rebooted the Mac, and then added the speeches back.  After the download, this fixed the problem.


Merge partitions after windows installation failure

This is a very common question. Again, here is the commands you need to enter in a Terminal application window.

I assume the untitled disk0s4 partition was created by the Boot Camp Assistant. If so, then use the command below to remove this partition. Otherwise, skip this command.

sudo diskutil eraseVolume free none disk0s4

The next two commands will remove the disk03 partition labeled OSXRESERVED and return the free space back to the disk0s2 APFS container partition.

sudo diskutil eraseVolume free none disk0s3
sudo diskutil apfs resizeContainer disk0s2 0

There may still be Windows boot files stored in the hidden EFI partition (disk0s1). These files can be removed by entering the commands given below.

sudo diskutil mount disk0s1
cd /Volumes/EFI/EFI
rm -r Boot
rm -r Microsoft
cd ~
diskutil unmount disk0s1


Screen capture software that streams to Apple TV?

Check out Erica Sadun's AirFlick, part of her free AirPlay utilities package. You may have to do some fooling around to get it to send the screen instead of a file, but that should actually be doable with VLC, if she hasn't already built it in.

What is the default "cursive" font for macOS?

WebPreferences has properties for each of the standard font families. See

https://developer.apple.com/documentation/webkit/webpreferences/1536642-standardfontfamily

Apple doesn't publish the defaults for each of these, but you can use an Xcode playground to quickly print them:

let prefs = WebPreferences()
prefs.standardFontFamily  // Times
prefs.sansSerifFontFamily // Helvetica
prefs.serifFontFamily     // Times
prefs.fixedFontFamily     // Courier
prefs.fantasyFontFamily   // Papyrus
prefs.cursiveFontFamily   // Apple Chancery


Time Machine error - The backup disk is not available - Using internal disk for TM

If you are using the volume directly on the Mac and you are likewise sharing that root folder of that volume, then correct. The hidden time machine files would be problematic.

If you exported a sub-folder on that volume, and placed the necessary Time Machine control files in place, then you should be able to use the exported volume as a time machine volume over the network.


Is there an easy way to remove an app from iTunes and all iOS devices?

Not sure which iTunes version you have installed but as of 10.2, once I deleted an app from the app list in iTunes, the app is deleted from all iOS devices the next time they're connected and synced.


Install OS X 10.7 to 10-10 on MacBook Air MD232

Hardware Requirements

Every Mac has a minimum supported operating system. Older versions of OS X will not run on a Mac with a higher minimum.

For example, the MacBook Air (Early 2014) requires OS X 10.9.2 or later.

EveryMac has a comprehensive list of Mac models and their minimum supported OS X.

Virtual Machines

To work around this, consider using a virtual machine for your testing; VMware Fusion, Parallels, and VirtualBox are all reasonable choices.


How to handle malfunctioning macbook after macOS upgrade while avoiding full reset

Same as my answer to No user to login in MacOS High Sierra, even though it may not be a strict duplicate...

I'd suggest nuke & pave, back to Sierra & HFS+, test the disk [as there are many utils that can test HFS but only one that can test APFS] then rebuild from backup.


"at" symbol is not working in everyplace

If you look on your keyboard, you should see the @ above one the keys, probably the number 2. Try the combination Shift + that number and see if that works.


System Preferences hangs when trying to open Display settings with an external monitor connected

So I figured this out, kind of.

I cloned and built https://github.com/CdLbB/fb-rotate, and flipped the external monitor around a couple times with it. Suddenly everything works, even after a reboot.

The only thing I can think of is that a config file somewhere got corrupted, and this utility rewrote it and fixed it.

Either way, it works now!


How does an iPhone import photos from the photo stream?

No.
When you delete an image from Photo Stream, there is a message (at least on iOS) that says something like

The image will disappear from Photo Stream on all your devices.

Hence, deleted means no longer in Photo Stream anywhere.


How do I enable the one-handed keyboard?

Keyboard switching icon

Hold down on the keyboard switching icon (usually a globe or smiling face) and on the last menu item, pick the right or left option. Note that this only works when more than one keyboard is enabled because the keyboard switching icon only shows when needed.

The 3 keyboard icons are for enabling the one-handed layout.

If you pick the left option, you'll be able to use the keyboard with only your left hand, and the same is true with the right option. The center option makes the keyboard two-handed again.

Settings app

In the Keyboard settings (Settings -> General -> Keyboard -> One Handed Keyboard), you can select between the keyboards.

This method works regardless of how many keyboards you’ve enabled.

Here's an example of the right-handed keyboard:


Downgrading from OS X Mountain Lion to Snow Leopard gets stuck at Apple logo

The reason you can't boot from from the USB stick may be because it's a version of Snow Leopard that predates the one your Mac shipped with. Is the source version of Snow Leopard you're using a retail disc?

Also, downgrading directly from a newer OS is not supported behaviour. I've seen it attempted successfully (at least superficially) on a few occasions and, among other things, the OS does downgrade but the data doesn't. So iCal's data is geared up for the newer OS, etc etc.

So. The only way you're going to be able to do this properly is going to be by wiping your internal hard drive with Disk Utility, installing Snow Leopard, then setting everything up from scratch (manually installing your apps, moving important data, etc). I know it sucks, but it's going to be the only way everything will work properly.


The traditional approach, e.g. with cron jobs, is to pipe standard error to a program like mail that's smart enough not to send you empty mail. The difference with launchd, as you've discovered, is that the mechanism for redirecting standard error is giving a StandardErrorPath for it to be written to, which isn't as convenient for this purpose as ending your crontab entry with | mail ….

My usual solution is to have a wrapper script check the StandardErrorPath and notify me if there's a problem. This can either be part of the same launchd job, so the checking happens before the next scheduled run, or you can have a separate job that just manages the error logs (maybe using a QueueDirectories key).

I think you could also, for example, use a named pipe as your job's StandardErrorPath, but I've never actually tried that.


Can anyone suggest strategies for coping with a 200MB/day Internet quota?

I hope you remember back to the days when 200MB/day was an incredible amount to have. :-)

There are some simple things and then some more complicated things.

Limit access by time of day

First of all, you can block times of day for connections by MAC address (advanced settings) on the Airport Extreme base station.  This can keep machines from pulling down files, updates, etc., without your permission.

Cache data with a proxy server

Second, you can install a "caching" proxy server, such as Polipo http://www.pps.jussieu.fr/~jch/software/polipo/, which will allow multiple machines to access the same content, fed from your iMac instead of the Internet.  You'll need to perform the same sort of proxy chaining as you currently do with GlimmerBlocker.  You should look around for a caching proxy that offers plugins for ad blocking, etc.

Limit your bandwidth so you cannot exceed your daily transfer limit

Third, you could perform what is called "rate limiting", "traffic shaping," or "QoS" (Quality of Service) (see http://en.wikipedia.org/wiki/Traffic_shaping).  You can do this by installing software (http://intrarts.com/throttled.html is one I have Googled but have not used) or by purchasing a home router that offers this option and putting it between your AE base station and the satellite router.  Here's a list from CNET: http://reviews.cnet.com/routers/?filter=500563_5554972_

With this option, you could do some rough math to figure out, given your peak usage, how much bandwidth to allow to your network.  I don't think the software solution will work with your iMac proxy solution since people do not connect through the iMac (but the caching proxy will help) so you may have to spend $50 or so on a router and configure the allowed bandwidth.

This will basically cause you to treat your 200MB/day satellite connection as a 18kbps modem assuming 24 hours a day usage.  If you really only use it eight hours a day, you could have the equivalent of a 56kbps modem.  Fudge up or down based on your comfort level.  It will stink but you won't have overages, and you can always "turn it off" if you need to make a big download.

It will also allow your entire family to download video or other media.  It will be self-correcting, in that it will be so painful to download high definition video that it won't be worth doing.


iTunes 12.2 broke the shared library feature from Mac to Windows

Apple removed Home Sharing for music with 12.2. The theory I've read on the Apple forums is that this is one of the concessions they had to make with the music labels in order to get Apple Music off the ground.

Here's a cnet article that mentions the feature change:

http://www.cnet.com/news/itunes-users-hit-stumbling-blocks-with-arrival-of-apple-music/

Edit: Home Sharing for music was indeed removed with the latest updates.

If you have airpods apple just started supported automatic device switching with the newest software versions (fall 2020). Here is a link to read more about it,
https://www.imore.com/airpods-automatic-device-switching
If you don't have airpods and new devices then you may be out of luck for now. Some other bluetooth devices use a button to switch between paired profiles but most don't in my experience. If the devices are all in different rooms it would be one thing but if you have them all on your desk then it is a harder problem. I will say you can disconnect from a bluetooth device without turning off bluetooth but often just as cumbersome a task.


How should a user of OS X verify whether backed up data comprises everything required for lossless restoration?

n8gray.org: Backup Bouncer

Improvements to Backup Bouncer were noted in March 2012 by Mike Bombich, developer of Carbon Copy Cloner.


It's likely to be in the spool file: /var/mail/$user. Because sometimes your mailbox will contain important messages (a failed cronjob task, etc.) you don't to check it every time by yourself.

Also, you can check man mail


Transfer downloaded iOS7 installer to home computer

You need to start by being aware that each different model of phone has a unique package for the iOS upgrades. So if you and your wife are not on the same model phone and the same carrier, there is a chance that your download won't work on her phone.

Assuming that you are on the same model phone (the size of the phone in GB doesn't matter), and if you are downloading your update via iTunes, then it will be stored on your computer somewhere. It will depend upon whether or not you are on a Mac or a PC, and which version of everything you have. A hard drive search for something like iOS_7* or ipsw should turn it up.

Copy that to your USB drive, and then copy it to your home computer. Open iTunes on your home computer with your wife's phone connected, and press and hold "Option" key on the keyboard (for a Mac) or the "Alt" key (for windows -- I think), and click the restore button. When it prompts you to a file, point to the file that you copied off of your USB drive.

Make a backup of the phone first. This method will cause iTunes to wipe the phone, and then you will need to restore it.


Is there any way to view word documents within Safari on the Mac?

One solution is to use Google docs — unless you hate Google :)

Install the NinjaKit extension so that Safari will be able to use GreaseMonley scripts
Install the Google Docs Viewer script from userscripts.org
Now Safari will show a small icon next to Office documents that redirects to Google for online viewing

Incidentally, NinjaKit is a great extension and there are plenty useful scripts on userscripts.org


How to find memory leaking apps in OSX 10.6.8?

Activity Monitor.app indicates how much memory each process running on your Mac is using.


‘Select, Select All, Speak Sentence’ are the options shown when there is no current selection. In your screenshot, a selection has been made, so the options change to be contextual to your selection, namely ‘Copy, Look Up, Share…’.

You can only bring up the first set of options without a selection, therefore this is only possible in a text input or textarea. You can make the entire page editable, thereby being able to place the cursor within without a selection, by running the following JavaScript in a Shortcut:

document.body.contentEditable = "true";


Mavericks, Minecraft, Mods and Parental Controls

You'll have to open up Terminal.app for just a minute. This is what you should enter:

sudo chmod 777 '/Users/sandbox0/Library/'
sudo chmod 777 '/Users/sandbox0/Library/Application Support/'
sudo chmod -R 777 '/Users/sandbox0/Library/Application Support/minecraft'

Obviously, you'll need to change out sandbox0 for your son's name, that was just the account I used to test it.

So what do these commands do?

sudo means you'll be executing the command as root to ensure you have full permissions. You will need to enter your password the first time under a nice, big warning.
chmod means “change mode” which will change the permissions of the file, with the Library folder, the Application Support folder, and finally with everything in the minecraft folder. (the -R means recursive, going through all the files and folders inside that one).

You may have to run the final command once in a while as new versions of Minecraft are downloaded and ready to be modded; a new JAR that Minecraft downloaded on his account will not allow you to edit it. If you will be doing this often, open the Applescript Editor, paste this in, and save as application.

do shell script "sudo chmod -R 777 '/Users/sandbox0/Library/Application Support/minecraft'" with administrator privileges

How to get the color burst wallpaper frames

The pictures in that advertisement do not come preinstalled on the MacBook Pro with (or without) the Touch Bar and do not seem to be provided by Apple separately. It appears that those images were used solely for advertising purposes and are not available. There are three similar "color burst" images with combined colors (See pictures).

Note: The photo quality have been degraded by 70% to allow for them to be uploaded.

If you would like to get the Photos you can make a feature request at https://www.apple.com/feedback/.


Well, as you mentioned, there is no official or easy way to do this.
The only thing I can think of is to create a "Shared Album" (Go to the album tab in the photos app and click the "+" icon, then tap the three dots in the upper left and click "Share Album"). The only thing is you will manually have to add photos to that album (Which is easy to do, just go to the "Library" view and tap "Select", select the photos, and then tap the share icon and "Add to Album").
Hope this is helpful!

Car audio doesn't work in iOS 10 ("No song")

After much troubleshooting, the issue was the Music app being "deleted" (hidden). Even if not running the Music app—and using Spotify, Maps, etc.—the car audio does not function properly without it. Restore the app via the App Store and the car audio comes back as it was before.


You may be able to do this with the "Extend a wireless network" option within the Airport Extreme, but a better solution may be to use power adapters to extend your network.


Can an iPhone use OS X Server's Calendar service without enabling iCloud calendars?

Yes, you can add an OS X Server calendar as a separate account through Settings → Mail, Contacts, Calendars → Add Account → Other → Add OS X Server Account.

This is a completely separate account to your iCloud account. You can allow sync outside of your LAN by forwarding the relevant ports.

"Turn display off after" setting is not saved

I would start with resetting the SMC and NVRAM on your system -- If I recall a lot of the sleep settings are in one of the two -- likely SMC.

To reset SMC: https://support.apple.com/en-us/HT201295

To reset NVRAM: Shut down computer. Hold Apple, Option, P, R on keyboard as you power on -- keep holding until you hear the startup chime a second time and let go.
Typically I use my left hand to get Apple, Option, P. Then right hand to press power and quickly get the R held down.


Continue writing iPhone Mail on Mac without the account configured on Mac

It's a feature called Handoff

OS X El Capitan: Pick up where you left off with Handoff
With Handoff, you can start something on one device (Mac, iOS, or Apple
Watch) and pick it up on another without losing focus on what you’re
doing. For example, you can start writing an email on your Mac, then
pick up where you left off in Mail on your iPhone. Or see a location
in Maps on Apple Watch, then explore the area in more detail in Maps
on your Mac.
You can use Handoff with many apps—Calendar, Contacts, Keynote, Mail,
Maps, Messages, Notes, Numbers, Pages, Reminders, and Safari. Some
third-party apps may also work with Handoff.

An app's Handoff icon at the left side of the Dock For Handoff to
work, you must use supported devices that are signed in to
iCloud using the same Apple ID and on the same Wi-Fi network.
The devices must be within Bluetooth range of one another (about 33
feet or 10 meters); make sure Bluetooth is on for your Mac (in System
Preferences) and iOS devices (in Settings).
Turn Handoff on or off   If you don’t see a Handoff option on your device, it doesn’t work with Handoff.
On your Mac: Choose Apple menu > System Preferences, click General,
then select “Allow Handoff between this Mac and your iCloud devices”

How to uninstall Xcode IDE without completely removing the dev tools

As of recent releases of Xcode 4 you can now get the command-line tools as a separate download and installer - it's a much smaller download too: http://developer.apple.com/downloads.

You'll want to uninstall an existing Xcode install with the command:

$ sudo /Developer/Library/uninstall-devtools --mode=all

before installing the command-line only tools.


El Capitan not installing after first restart

If the El Capitan install fails for any reason, it automatically rolls back to Yosemite.

Could be many reasons for it not to work like HDD issues, Install file corruption or space issues?
Also, Is it an older El Capitan installer? Downloaded a while ago? Apple's certificate expired a while back and it could be failing for that reason. Try downloading it again.


Is there any security risk if a malicious Microsoft Word (.doc) file is opened with the Apple Pages app?

Theoretically any file can be a security risk if opened in an application, be it via malicious macros, be it via being tampered with to cause buffer overflows, be it somehow else.
Practically Pages can't run Word macros so opening Word documents in Pages should be safe.


On the iPhone lock screen, how can I see just the number of unread mails?

Can I unlock my iOS, or access it's data some way, via PC?

In general, no. iOS devices where you have enabled hardware data protection on iOS 4 or later require the correct passcode to be entered. If you haven't enabled a passcode, the data on the phone is easily available to the thief assuming they have either minimal training and/or money.

So, as long as they can't guess the passcode from looking at smudges in the glass or recording your motions before the device is stolen - you are as secure as the passcode you have chosen. Most times when the government needs to bypass the passcode locks, they get a warrant for your home computer and take the key that iTunes uses to unlock the device and use specialized software to send that key.

Once someone is willing to spend thousands of dollars on either specialized hardware and software or thousands of dollars to hire someone trained in iPhone forensics to do the work, the chances of "cracking" into the device are higher, but still not assured if you have chosen a good passcode and not allowed your keys to be stolen by a backup to iCloud or let the thief get to your computer as well.


My Mac doesn’t help an admin user?! Help!

Go to your terminal and type the following command in:

dscacheutil -q group -a name admin

This will list the admin username.


After 5 days you might need to figure out where the backup is hanging. 45 gb means you have significant data getting backed up. Also, there’s not a good way to monitor things, so you might need a a split half search.

In this case I would disable backup of half the items and then see if backup completes in an hour or two. If not, disable half of the remaining items and repeat.

See this article for how to selectively back up some apps and data. - https://support.apple.com/en-us/ht204247

Once the backup succeeds, re-enable things half by half.

Worst case the backup never works and you have to back up to iTunes. Best case the smaller backup gets you past the log jam.


Launching applications with Quicksilver the “manual” way is so fast, I’ve never even bothered assigning a keystroke for one. If you did want a keystroke, you could limit the scope so it’s not active in certain applications, or so it’s only active in certain applications.

Also note that Quicksilver will very quickly learn that when you type “it”, you want iTerm by default and not iTunes, so you won’t need to remove it from the results entirely. And unlike Spotlight, you can find iTerm2 by typing something like “trm”.


Is there a way to update the emoji font?

The font file you need to use a more recent version of is /System/Library/Fonts/Apple Color Emoji.ttc and is about 135MB.

The High Sierra version of the file and the process to install it to /Library/Fonts can be found here:
http://stephenradford.me/install-high-sierra-emoji-on-older-versions/

Note that the Emoji & Symbol picker will not list the newer emoji added since your version of macOS. For that to work you would also need to update at least  /System/Library/PrivateFrameworks/CoreEmoji.framework and maybe some other files.


Force Spotlight to index a normally un-indexed folder

Well, in order to answer the implicit question stated in your headline: You can force Spotlight to index unindexed folders by creating a link to them in an indexed folder. Say you want to index something under ~/Library/, you'll be able to do that by creating a link under your home directory.

Unfortunately, I can't answer your question proper: While this makes Spotlight comments etc. accessible, it still does not cause image dimensions to appear in Finder. But perhaps this is a starting point.


Prevent employees from using anything else but my proprietary application

You will likely want to look at the Parental Controls (System Preferences). While it won't prevent them from moving around in OS X, it will prevent them from running other applications that you have not explicitly authorized.

How do I temporarily exclude a folder from a search?


How do I safely restore files to a shared folder after they were replaced with symlinks created by iCloud's "Optimize Storage" feature?

Yes, it's a pickle to have two competing cloud drive sync's running on the same files.  You need to ensure that iCloud, Google, Dropbox, Box, etc. are not using the same locations.
iCloud sync's the Desktop and Documents folders so make sure none of the other competitor cloud drive sync folders are not located on the Mac desktop nor documents folders.
I would have the problematic user disable the Google sync and download the documents from iCloud then move them to a new folder outside the Desktop or Documents folders.  Then ensure that the folder that Google uses to sync is also not in Desktop or Documents. Then enable the Google drive sync new location.  Move the files into Google drive sync folder and let them sync back to Google.  That should fix the problem once the other users sync them back down from Google.
If more than one user has turned on the iCloud Desktop & Documents sync feature they need to do the same thing. Except now someone has to figure out what's new versus old in regards to the files that have moved into individual iClouds over a period of time. So if that is the case, ouch... That's painful if it's a lot of files.
Decide on a single cloud solution and stick to it. Do not mix your cloud solutions.  This sounds like an accident. So hopefully it was just one user who did this.
Check the Google drive that's on the Google Cloud see if the files were all replaced with .cloud links. If so then the master copy should be on that one users personal iCloud.
Once you've resolved the Google mess.  Then the user can either continue to use iCloud or they can turn off the Optimize feature, download all their files (if they have enough local storage) and then they can turn off the iCloud Desktop & Documents feature if they really don't want to use it.  Otherwise they need to keep other cloud systems outside the Desktop and Document folders.


Hard drive and power consumption of current Time Capsule

Since it's a 2TB or 3TB storage you can be sure it's HDD, since the price is 'only' 299$ or 399$. There are for the moment no (commercial) 2TB SSD drives or maybe one or two which are really really expensive. On the product page is also stated that the Time capsule is ussing a Hard drive, otherwise there would be stated Soild State drive or similar.

Is it 'OK' to use the root user as a normal user?

Using your computer logged in as root all the time is like always carrying around all your keys, your passport, $5,000 in cash, that piece of paper with all your passwords written on it and the only photo you have of Flopsy, the adorable rabbit whose death broke your seven-year-old heart. Oh, and a chainsaw.

Which is to say, it's mighty convenient from time to time, because it means you can do whatever you want, whenever you want, without needing to go back home to get stuff or talk to your bank manager. But it also puts you at great risk of losing stuff, having it stolen (don't think that chainsaw will help you: you'll be streets away before you notice your wallet's gone), doing things you really regret later (impulse-buying plane tickets to Vegas while drunk), taking dangerous shortcuts (chainsawing through the lion enclosure fence because that's the fastest way to the pandas) and over-reacting (chainsawing your neighbour's car because his dog barks too much). And, when you think about it, mostly, you're just going to the office, going grocery shopping, hanging out with your friends. You don't need all that stuff with you all the time just for the convenience of needing it, what?, once a month? Once a week?

So, no, it's not OK to use the root account all the time. It gives you a tiny amount of convenience but puts you in a lot of danger. There's the danger of stupid mistakes having catastrophic results ("Hey, why is rm -rf * taking so long to run? **** I'm in /!"). There's the danger of acclimating yourself to the idea that all files are equal and you can just mess about with whatever you want, anywhere in the directory tree. There's the danger that any hack to your account is immediately a hack to the whole system, so now every single piece of software on your machine is security-critical. And even if you think you don't care about your machine getting hacked (after all, that photo of Flopsy is a real piece of glossy paper, not some ephemeral JPEG), I care about your machine getting hacked because then it's on the botnet that's mounting the DDOS attack against whatever internet service I can't access today.

Root is your spiderman costume. It gives you great power but requires great responsibility. It's there in the closet whenever you need it, so you don't have to wear it all the time.


Yosemite on an Early 2008 iMac 20" with 4GB gives too many beachballs

There are a couple of Things you could try:

run "Disk Utilities.app" from /Applications/Utilities and start 'Check Volume' and 'Repair File Permission' there are probably some issues here
start the "Console.app", also found in /Applications/Utilities/ and check for errors while starting
Clear the Caches either by starting the Mac in single User Mode (press and hold the shift-key while starting up) and restart the Machine again. Best would be to run 'Onyx' and clear out the Boot Cache.

Don't forget that spotlight would be reindexing your machine after an upgrade, so that could be an explanation for the slow performance at first.

https://www.bewebsmart.com/ipod-ipad-iphone/how-to-restrict-apps-by-rating/

If Parental Control restricts a certain age criteria, yes it can be a filter. There are filters like 9+, 13+ etc. If all apps are allowed by the admin, no warning will be seen on the basis of age restriction. It will be just metric to judge content of the app.


How do I get rid of this pop up when I try to select text?

That looks like you have a Chrome plug-in that is a web site reader.

On your screen shot one can see the "250wpm" (words per minute)in bottom right corner, that would be an indication that you have a reader plug installed.

Remove it or fix it.

Can I restore an iPhone from iPod Touch Backup?

Seems feasible. The last post on this site says someone got it to work. Do an actual backup (not just sync) though.


iPod Touch G4 disconnects from Belkin N+ Router at random intervals

I have had this issue with the D-link router at home from time to time. My solution was to set a static IP and manually enter the device's IP, subnet mask, gateway IP, and DNS server IPs manually into the device.


Pretty simple, and it will zoom anything on the screen, not just text, so that's even better.

On your iPhone go to Settings > General > Accessibility > Zoom > Click to turn on.

See my attached screenshot for a few more commands while zoomed in.


How to change the ad-hoc WiFi name in OSX?

Apple Thunderbolt display not turning on when connected to ASUS Z87 motherboard

Okay, I have figured it out myself :)
Feeling extremely happy.

Steps:

Enter BIOS setting. For most of the computer, you just have to press
F2 while computer starts.
Enter Advance BIOS setting mode.
Enable iGPU and Multi-Monitor option in the Graphics section.

That's it. Restart your computer and Enjoy the terrific Apple thunderbolt display quality in Windows operating system.

My PC specs:

Motherboard: ASUS Z87 Expert
CPU: Intel Core i7 4790k
Discrete GPU: Sapphire R9 270X 2GB Dedicated
and Apple Thunderbolt Display 27" :)

Any Windows operating System (7/8/8.1) will work but my my operating system is Windows 10 Technical Preview.

Here is a screenshot


Opening and cleaning a MacBook Pro (retina 2012)

Assuming the warranty is expired, you'll be fine. If you want to just remove the dust from the inside, you're on the right track. Get a can of air, a vacuum, and a pentalobe driver set.

Don't actually vacuum the inside though - turn it on and hold the nozzle up to the outlet of the area you're blowing the dust from. Static won't be a problem as long as you don't touch the computer with the nozzle.


As I'm sure you know, troubleshooting is a process of elimination and often requires patience.

The first thing I would do is remove any non-Apple hardware (if connected) and try again. If this makes no difference, then I would proceed with resetting the NVRAM of your iMac Pro.

How to reset NVRAM on an iMac Pro

Follow these steps:

If you have a firmware password, first disable it before proceeding
Fully shut down your iMac Pro
Switch on your iMac Pro
Immediately press and hold the OptionCommandPR keys.
Keep the keys down until after the Apple logo appears and disappears for the second time.
Allow your iMac Pro to finish booting up. (NOTE: Upon reboot you may need to reconfigure some of your System Preferences (e.g. sound volume, display resolution, startup disk selection, time zone, etc).
Now reboot your iMac Pro and use the Command + R keys to boot into Recovery Mode and see if you can get the Startup Security Utility to work.

If this works, all good! If not, let's investigate Single User Mode again.

Single User Mode

Since your iMac Pro itself seems to be running fine in normal usage, another thing to investigate is the issue you're having booting into Single User Mode. Some additional things to check:

If you have a firmware password you must disable it first. You can't boot into Single User Mode (or Verbose Mode either) with a firmware password enabled. So, if you have one, disable it and try again (I suspect if you had one it'd be disabled anyway if you followed my steps for resetting the NVRAM, but just wanted to be thorough and mention it again).
If you didn't have a firmware password, or if disabling it doesn't work, then try booting into Verbose Mode instead. The process is the same, except that you're holding down the command + V keys instead. Verbose Mode is actually a normal boot, except that you're seeing a description on screen as to what's actually happening during the boot process. You'll know you're in verbose mode when you start seeing white text on a black screen.

If you can boot into Single User Mode, great! If not, let us know if you see anything of interest when booting via Verbose Mode.

About the AdjustBusy timeout error

The AdjustBusy timeout error while booting into Single User Mode is interesting and one of the reasons I asked at the outset for you to remove any non-Apple hardware. Typically this relates to an IOService (don't worry about the technicalities - it's basically just referring to input/output devices and drivers).

Anyway, if you're still seeing this error, I would do the following:

Boot your iMac Pro normally
Launch the Terminal app (found within your Applications > Utilites folder)
Type (or copy and paste) the following command:

kextstat | grep -v com.apple

Press Enter
Within moments Terminal will list all 3rd party kernel extensions (Note: you may need to stretch the Terminal window so it's easier to read).

The above process is used to identify any 3rd party extensions you have installed. While this is a list of all 3rd party kernel extensions, I'm interested specifically in anything you don't remember installing, or something that belongs to software you no longer use. Also look out for anything that could be related in some way to LaCie hardware (either current or old) or to SoftRaid.

Let me know if there's anything of interest.

Where is my apple account picture stored on my mac?

I don't know where it's stored, but I know how you can find it...

Open Contacts, and navigate to your card, then click on the image. A box will appear with four options in the sidebar. Click "Recents", and one of the images it displays will be the one you want. Next, click on this image to set it as your Contacts image, the click "Done". Now open a new Finder window, then press Shift-Command-G. Copy the following path into the dialog box that appears: ~/Library/Application Support/AddressBook/Sources/ Click "Go". You will arrive in a folder which contains a number of other cryptically named folders. One at a time, open each folder, then Click the "Date Modified" header in the Finder window to sort by date. In one of these folders, date modified today, you will find the image. It will actually be there twice. There will be a low res version, and a slightly higher res version. (The reason it will be date modified today, not back whenever you took the photo, is because this is the folder for "Contacts" images, not the original folder.)


How can I stop spaces from switching automatically?

Stop Spaces from switching spaces due to an app coming to the foreground:

defaults write com.apple.Dock workspaces-auto-swoosh -bool NO && killall Dock

Or via the GUI: System Prefs > Spaces and then uncheck the checkbox at the bottom: "When switching to an application, switch to a space with open windows for the application"

Stop (slow down) Spaces from switching spaces if your mouse presses against the edge of the desktop:

defaults write com.apple.dock workspaces-edge-delay -float 60 && killall Dock


You might need to provide more details (are you getting any error messages? Are you manually managing you iPod's music or automatically?) but here's the best place to look:

Connect your iPod to your computer, fire up iTunes and click your nano's icon on the left of the iTunes window. Look for the podcasts tab and make sure the sync Podcasts and 'automatically sync podcast' tick boxes are selected.

There's a really clear step-by-step here.


Change file creation date to modification date using terminal

To use @user3439894's answer with find, use the -exec command {} + clause, and put the for loop into a sh script:

find some/path -iname \*.img -exec sh -c 'for f in "$@"; do m="$(GetFileInfo -m "$f")"; SetFile -m "$m" -d "$m" "$f"; done' sh {} +

The 2nd "sh" will become the $0 inside the spawned shell, and the .img filenames will be the positional parameters $1, $2, ...


Can gamecenter friends see what apps I've installed on my iPhone?

Your friends can see the games that have access to your Game Center account (this works accross multiple devices since you can have a single Game Center account for multiple devices).

The access to the game center needs an explicit autorisation. Most of the time on the first start of the game it will prompt you if you want grant access to the game center (or not).


This can be done with a bit of hacking. ;)

Before proceeding, you should backup your Terminal’s preferences file:

cp "Library/Preferences/com.apple.Terminal.plist" "Library/Preferences/com.apple.Terminal_OLD.plist"

Check to see if the file was copied successfully:

ls "Library/Preferences/com.apple.Terminal_OLD.plist"

If it prints Library/Preferences/com.apple.Terminal_OLD.plist then you're good to go. Otherwise make sure you typed the first command correctly.

Now for the fun part, you can modify the internal settings of the Terminal by typing:

defaults write com.apple.Terminal "ApplePressAndHoldEnabled" -bool true

Close the Terminal completely by first closing all open Terminal windows and then right clicking the Dock icon and choosing Quit.

Open the Terminal again and smile :)

Let me know if this doesn't work on your system.


You only ever have two options with iOS - stay on the iOS you're currently on, or update to the latest your device will support.

Apple stops signing all older iOSes within a few days of releasing a new version, meaning that even if you could install it, it would not activate.

As the iPad 2 is supported on iOS 8 [currently 8.4.1] this is your only choice if you wish to update.


Enhanced (local) dictation in Mavericks 10.9 not working

It's possible the Enhanced Dictation language pack was corrupted when it was downloaded. You could try deleting it and re-downloading it.

First, turn off Enhanced Dictation in System Prefs > Dictation. When you uncheck the box a panel will slide down that you can just Cancel (which will turn Dictation off). Next, open Finder and press shift-command-g simultaneously. In the dialog box paste the following and click go:

/System/Library/Speech/Recognizers/

In the Recognizers folder there will be two folders. Delete (or rename) the folder called SpeechRecognitionCoreLanguages. It will ask you for your password to delete (or rename) the folder. After that you can go back to System Prefs > Dictation and turn Enhanced Dictation back on. It will show you your download progress in the bottom left corner of the System Prefs window.


Is it possible to enable 1.5x scaling using HiDPI on OS X?

No, this is not possible as it would result in a significantly distorted image with loss of image data. There is no way to accurately display one dot over 1.5 x 1.5 pixels.


What is the impedance of the line/headphone jack on MacBook Pro Retina?

I couldn't find the specific details for the new MacBook Pro Retina machine, but these specs are pretty universal across the whole MBP lineup and should help you match a pair of headphones:

  Line/Headphone Output

  The line/headphone output is automatically selected for audio output if no external device is detected at the S/PDIF optical digital output port. The line/headphone output supports a stereo data stream at bit depths of 16, 20, or 24 bits per sample and at sample rates of 44.1 kHz, 48 kHz, or 96 kHz. The line/headphone output volume can be adjusted from 0.0 dB to -95.25 dB.

  During playback of a 1 kHz, full-scale sine wave (44.1 kHz output sample rate, 24-bit sample depth, 100 kΩ load, unless otherwise specified) the audio line output has the following nominal specifications:

  Jack type: 3.5 mm stereo
  Maximum output voltage: 2 VRMS (+8.24 dBu)
  Output impedance: < 24 Ω
  Frequency response: 20 Hz to 20 kHz, +0.5 dB/-3 dB
  Signal-to-noise ratio (SNR): > 90 dB
  Total harmonic distortion + noise (THD+N): < -80 dB (0.01%)
  Channel separation: > 75 dB

  Note: For best results, equipment plugged into the line/headphone output jack should not connect the audio ground to other grounds, such as the chassis or “green-wire” ground.

The answer to that post doesn't contain a reference link I'm afraid.

I did find a link on the Apple Support page that says the Mac Mini's headphone jack is 10 Ohms.

All this is to say: yes, you're correct. Those headphones are far too high a load for the limited-power amplifiers in your iDevices and your MacBook Pro.

You want a lower impedance headphones. They're more efficient at converting the electrical signal they're passed in to sound you can hear. More efficient means, for the same power electrical signal, higher volume reproduction.

Aim for something the less-than-or-equal to 64 Ohm range if you can.

Revoking and requesting a new distribution certificate in apple dev center

I had this exact problem just today (Aug 13 2015)

Go into the member center, find the certificate, and revoke it.  Leave the member center.

xcode 6+ will automatically find the certicate has been revoked and will create & download a new one when you carry out an action that requires it.

I sometimes find it also helps to delete your account from Xcode->Preferences->accounts and add it back in.

Indeed it scared me the first time I tried it.


iTunes or other RSS/podcast reader that can retrieve whole podcast, I.E. transversing pages?

I don’t know of an app that supports this.

Perhaps you could add more than one feed:

http://venganzasdelpasado.com.ar/posts.rss
http://venganzasdelpasado.com.ar/posts.rss?page=2

And have iTunes handle it that way?

Alternatively, you could create your own RSS feed based on the website’s HTML, rather than use the one the website is offering which is limited to 5 items. That way, you could have more entries in the feed. This can be done using FeedWeaver, a free online web app.


Can I get a new iOS on my 1st generation iPod touch?

Unfortunately, there is no way to do that. Due to hardware limitations new iOS versions only run on newer devices which typically have faster processers, more RAM, and/or better graphics controllers, depending on the device.

Which ios devices support offline speech recognition

It may be only those devices with the A9 processor.  If so, that would be iPhone 6s, 6s+, and iPad 7th Generation.

It seems logical that the A10 (iPhone 7, 7+) would also do it, but I don't know.


LockFile is one of the directives of Apache ≤ 2.2. This was replaced by Mutex in Apache 2.4, which is the version of Apache installed with OS X 10.11, El Capitan.

Edit the file /etc/apache2/extra/httpd-mpm.conf to remove this part:

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
<IfModule !mpm_winnt_module>
<IfModule !mpm_netware_module>
  LockFile "/private/var/log/apache2/accept.lock"
</IfModule>
</IfModule>

Then check config apachectl -t and restart sudo apachectl restart.

Find my iPhone: how to identify each device?

It's too late now to identify the iPhone.  This must be done prior to losing the device, when you're able to provide a name for it.  Find iPhone doesn't list the specific device.

To name the device, go to Settings -> General -> About and in the Name field enter a specific device name (for example, 'PaulJ's iPhone 5s').  Then, when you need to locate the device, it will get the name you entered and it can be identified.

The only thing you can do now is the process of elimination.  Figure out which of the 3 devices listed is not accounted for someplace or, perhaps, not turned on.


How do we set OS X Lion sync to show warning before data on computer is changed?

If you still have your snapshot backup of your OSX Snow Leopard before you upgraded to Lion (you did backup didn't you?), then there is a solution to getting iSync back up and working under Lion :

slashusr.wordpress.com

Extract follows :

  Before installation of Lion, I had taken a full disk image of my
  previous Snow Leopard installation using the excellent SuperDuper!
  Disk cloner.

  This was more from a backup and recovery perspective, but allowed me
  an unexpected solution to the iSync quandary – on a whim, I attached
  the Snow Leopard disk to the Mac running Lion, and clicked on the
  iSync application. Voila! iSync works exactly as it should!

Hope this helps.


Can I use my 2011 iMac as a Thunderbolt display for my PC?

iMacs can be used in Target Display Mode, but only from another Mac.

This is a specific support mode, Mac to Mac, it is not the same as connecting an external display to a graphics card.

See OS X Yosemite: Use another Mac as a display


Can a Lenovo T430s with Thunderbolt use 2011 iMac in target display mode?

Just got off the phone with Lenovo tech support after unboxing my T430s/i7 because it didn't have a Thunderbolt symbol on the back... just a DVI symbol. Confirmed: NONE of the 430's they're shipping even HAVE it yet. I'm sending mine back, suggest you do the same. The internet is saturated with references that they have it that all sound as though they are informed by press releases... and Lenovo chat even tells you they have it... but no joy. Technology never fails to disappoint.


Automator workflow or AppleScript to close Safari after a period of time

Here is the AppleScript code, which you can put in your workflow, by implementing an AppleScript item, and copy-paste the code in.  The time is configurable, but you need an exact sleep time, which I can add if you could elaborate some more on the time.  Here is the code via CulturedCode.

global quit_after, check_every

set quit_after to 2700
set check_every to 10
set minute to quit_after / 60

display dialog "Check is performed every " & check_every & " seconds. Things will be quit after " & minute & " minutesof system inactivity."

on reopen
    display dialog "Check is performed every " & check_every & " seconds. Things will be quit after " & minute & " minutes of system inactivity."
end reopen

on idle
    set idletime to do shell script "echo $((`ioreg -c IOHIDSystem | sed -e '/HIDIdleTime/ !{ d' -e 't' -e '}' -e 's/.* = //g' -e 'q'` / 1000000000))"
    if (idletime as integer) > quit_after then
        tell application "System Events"
            if ((name of processes) contains "Safari") then
                tell application "Safari" to quit
            end if
        end tell
    end if
    return check_every
end idle


Symbol/Special Character use in OS X and iOS

Viewing Special Characters
The good news is that this part should almost always 'just work' on OS X and iOS devices. Encodings are usually handled intelligently, Unicode fonts are installed, and font substitution does its job.
If you do encounter problems, be sure to specify the encoding as Unicode (UTF-8) when saving. If your text editor doesn't allow you to specify an encoding, it's a fairly safe bet that this is what it's using.
Since Markdown files are plaintext, you don't have to worry about fonts. If you are using rich formatting, though, Lucida Grande, Arial Unicode, and Apple Symbol are all good options. But, again, OS X and iOS generally switch to another font seamlessly when the main font doesn't support a character.
Entering Special Characters
Both OS X and iOS include built-in text replacement tools that will let you insert your symbols easily.
OS X
Open System Preferences-> Language and Text-> Text and click the [+] button. Choose a keyword to be expanded and paste in the special character. You'll have to create snippets with unique keywords for each character.

iOS
Copy a special character. Open Settings-> General-> Keyboard-> Shortcuts and tap the [+] button. Paste the character under Phrase and enter a unique keyword under Shortcut. Tap save. Again, you'll have to create snippets with unique keywords for each character.

If you like, you can use the excellent TextExpander to do the same thing, but it isn't necessary in this case.


One Hard Drive to backup two Macs with Time Machine, then recover from one, then the other?

It is possible to use an external drive to back up two Macs via Time Machine. Per this thread, the backups will be stored separately, without any special setup needed.
Per pulling specific files from another Time Machine backup, you may want to refer to this thread. It should be doable to search that backup volume without having to install the entire backup onto another machine using the restore feature.


Removing "shift" from a letter on iPad Pro with Apple smart keyboard

Turn off autocapitalisation in settings>general>keyboard, I don't have an iPad Pro so not entirely sure if it will work but it does with my Bluetooth keyboard.


In Terminal.app you can change the default encoding in the Advanced settings. This will be set before it spawns a shell.

Looks like iTerm2 has the setting under Preferences, Profiles, Terminal.

Is that 'the very source' you are looking for?


Can Time Machine be setup to back up only one folder?

Unfortunately not. However, you can exclude individual folders from Time Machine.

It may be possible using the command line utility tmutil however


A failed update that resulted in an unmounted disk0s2

You should download the app Mountain.  This app places an icon in your menu bar. When opened it lists all volumes on your machine and you can mount or umount them. The app can be downloaded for free but you may have to pay for extended use - $6 I believe. I am in no way affiliated with Mountain, just a happy, long time owner.

Will my iPhone ring once Lost Mode is deactivated?

Normally if a device is in Lost Mode, you can just play a sound using Find My iPhone directly. Choose the Play Sound option which will play a sound on the device for 2 minutes at full volume overriding silent.

If you still wish to call the device, you can disable Lost Mode and make the phone call normally.


Moving Recovery HD partition to end of disk

Answer to Posted Question

When you enter the diskutil command to resize your boot partition disk0s2, the recovery partition disk0s3 will automatically be moved. You do not want to move this recovery partition to the end of the disk using a separate command. In other words, you are trying to do the wrong thing.

See Merge partitions with Macintosh HD for the correct procedure.

Response to Comment:  What if I want to leave some free space in the middle, e.g. for another partition later, but have the recovery partition at the end?

The recovery partition should always follow after the boot partition. For example I have Yosemite installed in partition disk0s5 and El Capitan in partition disk0s7. Both partitions are followed by their respective recovery partitions. Below is my current partitioning.

I have 100 GB of free space between partitions disk0s6 and disk0s7. I could, for example, install Linux in this free space. (For the curious, partition disk0s9 is a second EFI partition which contains the rEFInd boot manager.)

To determine the limits for resizing your partition, use the following command.

diskutil  resizevolume  /dev/disk0s2  limits

  When a partition is followed by a recovery partition, the previous command will display the correct minimum size and display the maximum size to be to the current size. The actual maximum size may be larger than this value. You will need to use the gpt command or some equivalent method to determine the free space the follows the recovery partition.

For example, to change your partition size to 110 GB, you would enter the following command.

diskutil  resizevolume  /dev/disk0s2  110G

To change your partition size to the maximum size of approximately 120 GB, enter the command

diskutil  resizevolume  /dev/disk0s2  R

You can enter the command man disktuil, for more information.

The smart covers, generally do leave the vertical stripes. This happens when the fold areas of the cover do not touch the screen when it is closed. If you remove the smart cover fold it up and hold it horizontaly while wiping down the screen you will remove these stripes.

I have found that after owning 2 covers, both ployuretherene, that the microfiber lininng does start to fade away, but this like most things will be determined by the amount of use, and whether you take care of the cover.

Try not to let the microfiber part touch any dirty surfaces when it is off, or you are using it as a stand.

To clean the microfiber lining you are better to use another microfiber cloth.

They have changed since first release. My first one was a lighter green on the outside and grey on the inside, the covers now all have matching inside colours and slightly more contrast in the clolour of the outside

How do I update my Apple Watch 4 to watchOS 6 with an iPhone 6?

The message you're getting is the same message all users will get until they upgrade their paired iPhones to iOS 13. In other words, you're not just getting this because your iPhone isn't capable of running iOS 13.

Unfortunately, if you're really wanting to take advantage of any of the new features in watchOS 6, you'll need to pair it to an iPhone running iOS 13 before you can upgrade watchOS. And, in your case, this means upgrading your iPhone too.


Stop messages to my new iPhone from appearing on my old iPhone

You need to disassociate your Apple ID from iMessage on his iPhone. You can do this by following the steps outlined below. Don't worry, iMessage/FaceTime account settings are separate to iTunes account settings (so you can choose to have different Apple IDs for each)

Open the Settings app
Scroll down to and tap 'Messages'
Scroll down to and tap 'Send & Receive'
Tap 'Apple ID' (which should list your Apple ID)
Tap 'Sign Out'

This will disassociate your Apple ID from iMessage on that iPhone and still leave it intact on your new one. Your husband will still be able to send and receive iMessages using his number. You will probably want to do the same for FaceTime too otherwise he will receive FaceTime calls for you and vice versa!


How do you extend the time required to trigger hot corner actions?

I do not know how do delay the triggering, but you can add modifier keys to the hot corners in order to avoid accidental activation:

Hold down ⌘,⌥,⇧ or ctrl while selecting an option from the list.


Try to rule out the causes... Go to your inlog page of your mail account on your pc and try with your password. If you can access the mailbox, then you know it's your iPhone. If you can't, it's you.

If you can access your mailbox on the web, then make sure you've configured your mail-account correctly. You can always try Google to search for a setup for your e-mail client. For example "How to configure hotmail with iPhone", or so.

And as a last resort, you can delete your mailbox and re-add it. Your iPhone will automatically rebuild your inbox, so nothing will be lost.

If you're using a POP-account (like hotmail), I could recommend an IMAP-account (like GMail).


How do you run a script after a network interface comes up?

The following works on Mac OS X 10.11.3 (El Capitan)

Create a file: networkchange.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" \
  "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>networkchange</string>
  <key>LowPriorityIO</key>
  <true/>
  <key>ProgramArguments</key>
  <array>
    <string>/Users/Shared/bin/networkchange.sh</string>
  </array>
  <key>WatchPaths</key>
  <array>
    <string>/etc/resolv.conf</string>
    <string>/var/run/resolv.conf</string>
    <string>/private/var/run/resolv.conf</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>

Then, register by running the following commands in Terminal:

launchctl load networkchange.plist
launchctl start networkchange

Note that the script is run by the user registering the plist.


Use one AppleScript to toggle on and off (1 or 0)

To get the state I would use something like:

set sms to (do shell script"pmset -g |grep \"sms\" | awk '{print $2}'")

Then:

if sms is "0" then
  do shell script"pmset -a sms 1" with administrator privileges
else
  do shell script"pmset -a sms 0" with administrator privileges
end if

Note the "administrator privileges"  this is used  because you will not be able to use 'sudo' because there will be no interface for you to type your password.

The "administrator privileges" will display a Normal OS Authentication dialogue for you to enter the user name and password.


Battery service and insanely low maximum charge

You need a new battery.

This is confirmed with the following two conditions as stated in the question:

  When checking it further, I found that my battery status is "Service
  Battery"

  I used coconutBattery to check and found that the Full Charge Capacity
  of my Mac is insanely low

Your battery, according to it's manufacture date, is over 3 years old, so it's not out of the norm for it to begin failing at this time.

Replacement batteries are fairly inexpensive and fairly simple to replace ("simple" as in not a complex procedure), but it's considered "difficult" because it's glued into position so it requires diligence to remove.  ifixit.com has an excellent step by step guide if you want to tackle this yourself.


It sounds like your touch is consuming more power then your USB port can deliver at run-time.  See if you can find a PC that can supply enough current to get it to boot on a PC and use one of those non-apple sanctified recovery software.


Not to take away from Allan's or drivec's answers, as I do think they have pieces of the puzzle, but the real answer is a little more complicated.

drivec is correct about a 'bug', but the bug is actually an interaction issue between iOS 11 and the iOS App Store.

This bug presents itself by listing apps as having fresh updates, when many of them do not!

Example

I have an iPhone 6s, as does my wife. I also have a number of apps I've developed, available on the App Store. As you would imagine, I have these apps installed on my iPhone, as does my wife.

Now, here are the interesting things:

During the last couple of weeks, in the Updates tab within the App Store app on my iPhone, I've seen a number of my apps listed at various stages. Now, these apps have not been updated since Feb/Mar/Apr of this year!!!
My wife's iPhone does not list these apps as having updates available, even though the same apps are installed on her phone. So, I got update notifications for apps I know have not been updated, and my wife hasn't received the same notifications.

The first time this happened I was rather confused, to say the least. I looked at my apps on the App Store and they still showed me as the developer, and they still showed the correct version numbers and in the Version History the correct timeframe of when the latest version was released. But, if I go back to the Updates screen, it'll show 2 days ago, or a date from last week, etc.

I reported this to Apple and they are aware of it (having received reports from other developers). And it is something they're working on.

Finally, Allan is also correct because the dates shown on the Updates page does indicate the date the updates were installed, while going into the App's individual pages and looking at the version history shows the date the app's latest version was released.

However, because of this bug, what is happening is that people are installing updates when in fact there is no need to do so, but when they do the dates appearing on the Updates tab change to the more recent date, even though the exact same version of the app may have been released months or even years earlier. And, since this bug is not necessarily presenting itself on all iPhones, or even with the same apps on different iPhones, it's only adding to the confusion.

NOTE:

When speaking with Apple about this, they informed me that they were updating apps so that they're signed with Apple's latest signing certificate. However, in those cases, Apple was pre-populatng the "What's new" text with the following text:

  This update is signed with Apple's latest signing certificate. No new
  features are included.

So, if apps are listed as having updates available, and the above text is shown, then they're not being affected by the bug I refer to here in my answer. However, it is possible that perhaps they're appearing in the Updates tab because of the certificate signing, and for some reason the "What's new" text isn't pre-populating correctly.


Short => So far, it's not possible at the Moment.

There are some Fake Unlocks for an iCloud Activation Bypass but if I'm correct - this are not working solutions.

You have to be careful, if the Seller doesn't even know the iCloud/ApplID Mail (normally you don't forget a e-Mail uh?) - otherwise he would be able to reset Password via Apple

Note: Not sure if an iCloud unlock would even be legal in every country!


Look at your preferences and make sure that the account is properly enabled.

If it is, try signing out and signing back in to see if that solves the problem.


iPhone 4s dropped-now the screen is black

It sounds as if it may be a simple case of the cable connecting the screen coming loose - the fact that the digitizer works could indicate that the cable isn't seated correctly - i.e. some of the connections are being made but not all of them. You say that you replaced the screen yourself, so I assume you're fairly competent at taking it apart again... If so, try doing this, removing the cable connecting the screen, and then reseating it.

Alternatively, it could be that the impact has broken the part of the screen required to display things, in which case, I'm afraid you're looking at replacing it again!


Transfer iMessage Archive to new Macbook

Since your message archive didn’t migrate the first time, I would do this:

Connect a hard drive to the old mac and let Time Machine make one backup - you can configure it to skip large files if you have lots of videos and photos you know can transfer, and you can delete any large apps you know you won’t want to back up or migrate - so light cleaning before one backup.
Then - see if you can update the old OS - I would update it to the absolute latest since that will do two things. First is it runs migration to make the older data ready for newer OS. Second, it makes the migration assistant newer so you’re not bringing data from 7 years back OS to the latest.
Erase your new Mac (back up any files needed) and re-run the migration from the updated Mac or a second backup of the upgraded Mac if you want.

I use the PhoneView app to manage messages on macOS so that might be an option if Apple can’t update and migrate the data with their normal tools.

http://www.ecamm.com/mac/phoneview/

It’s targeted at managing messages from macOS, but the free trial might show you if it will help manage / archive your messages in a meaningful way on the mac side. I’m sure someone knows forensically how to parse the database files, but that needs some special work based on your exact macOS version. Maybe someone with that skill will see this and answer how to directly open the files from ~/Library on the old mac and then transform them / process it to load from the newer macOS app.


To use an AirPrint printer the iPhone/iPad/iPod needs to be connected to the same local network that the printer is connected to. The printer can be connected via wifi or an Ethernet connection that connects to your wifi network.

If the iOS device is connected via the phone mobile data network then it can't print to using AirPrint.

Why is your iPhone not connected to the wifi network? Is it because you are trying to print to the printer when away from home? Or is it because you have a large property and you are out of range of your wifi network?

While you can't use the native AirPrint when not connected to your home wifi, you can use  HP's ePrint service. This works by your printer having its own email address. You can email documents to the printer that it then prints.

The service is somewhat limited when compared to AirPrint, as you need to be able to get whatever you are printing into a document and be able to email it. So many apps that support AirPrint can't be printed from using ePrint.

Does erasing Macintosh HD then restoring from Time Machine result in the HDD being reformatted?

Klanomath's procedures are 100% correct if it's a hard drive.

I use a tool named Scannerz to evaluate drives and it's extremely conservative. If you find bad blocks their procedures are pretty much exactly what Klanomath described, except it will be quite evident how extensive the damage is during testing. SMART technology only finds bad sectors if a write attempt to them has been made and fails. If there's a lot of damage on the drive and it's never been used because it's in free space, SMART will never know about it but Scannerz will pick it up. Zeroing the drive as described will force sector reallocation, and if the supply of spares is exhausted, the operation will fail.

If it's a manufacturing oddity that yielded a few bad blocks, the drive can be recovered by reformatting as Klanomath described. If it's extensive, you could probably partition the bad areas out but that's a risk I wouldn't take. I know some people have done it with success, but you end up with a drive with multiple volumes where one likely existed before.

As far as SSDs go, ideally their drive management software is supposed to pull bad blocks when they're encountered during a write operation. Unfortunately, an SSD, like an HD can develop an odd block here or there that just fails while it's holding data. The problem here is a dilemma, because the people responsible for writing that code must ask themselves whether or not they should just yank a block right out of the middle of an existing file and replace it with a blank, or should they leave it in place, and let the user try to recover what they can from it. This problem is rare, but it can happen.

In any case, typically there are trim and garbage collection routines that an SSD uses that will (hopefully) automatically pull the bad blocks and correct them after a failed write operation. On some SSDs, these may occur while the system is in use, on others they may occur when there's a quiet time of a few minutes.

Steer clear of any tool that tells you it's going to take a bad sector and "repair" it. There's no such thing. That's a dishonest marketing trick that has it's roots back in the 1980's when drives were using MFM and developers could actually gain access to the drive directly, and even then, it was at best only sort of possible to do it. Those days disappeared with IDE when the controller was put right on the HD.  Scannerz, for example, has an option to re-map sectors, but a warning will flash up telling you not to do it and that any information in the bad block is already basically dead, and the manual has a warning about a page and a half long, once again, basically telling you not to kid yourself.


In Mail.app 6.0, is there a way to drag-select parts of message bodies?

I had the same issue after upgrade to 10.8, had some old emails sitting open that I had minimized, closed all of them and then quit Mail. After restarting the issue went away, had previously tried to quit/restart/change layout with no luck.


Forgot to turn off Hotspot, tethered via USB along with direct Ethernet, end result?

I actually think there's little reason to be concerned, provided in Settings > Network, your Wi-Fi or Ethernet is ahead of iPhone USB in the left-hand list. OS X will go down the list and pick the first network provider that it needs to. So long as your WiFi stays up, you're fine.

I confirmed this by opening Network Utility and examining the transfer stats. You can see in the attached screenshots that all the action (packets) are happening over WiFi, hardly anything over iPhone USB.


Impossible to redirect subprocess stderr on macOS

This particular behaviour have nothing at all to do with any "impossibility" of redirecting subprocess stderr on macOS. It is not impossible, and works like you would expect - i.e. similar to Linux and FreeBSD.

The gotcha here is that you're using different PHP configurations on those setups. It seems you're not using the stock supplied PHP, but rather something else - but I'll explain according to the stock PHP considering that the same will apply to a custom install.

The way PHP works is that it outputs these types of errors messages according to the setting of the "display_errors" configuration directive. You can choose to either mute it completely (i.e. never output the error), output to stdout (the default) or output to stderr.

You'll commonly set the value of display_error in /etc/php.ini - if you haven't got a php.ini file, or display_errors is not set in it, it will default to stdout. If you're using a custom built php, the location of the php.ini file will vary.

You can test this out by performing the following in the Terminal:

php -r 'foo();' 2>/dev/null

Produces

Fatal error: Uncaught Error: Call to undefined function foo() in Command line code:1
Stack trace:
#0 {main}
  thrown in Command line code on line 1

However running:

php -d'display_errors=stderr' -r 'foo();' 2>/dev/null

Produces no output.

You can also use 1>/dev/null to redirect stdout, and then you'll see that the behaviour reverses between those two examples.

Note also that the setting "on" for display_errors is the same as "stdout".


Confounded by permissions problem on NFS share

Your noowners mention solved all of my issues. I would make sure all of your options are being applied w/ nfsstat -m -- mount_nfs likes to remove / add options and not list them when you just type mount I also am using launchctl configuration that runs a mount_nfs command, since automount was being unpredictable. I do see an s (setuid/setgid) up there in the permissions... I'm using nosuid...

Here's my working mount_nfs line, you probably can remove some of the options (some are duplicates), but I feel better having all the variations for some reason ;)

 mount_nfs -o "vers=3,noowners,nolocks,nolockd,nolock,nonlm,automounted,nosuid,hard,bg,noresvport,intr,rw,tcp,nfc"       <server>:/exports/myexport /Volumes/myexport

From ls -l from /Volumes:

drwxrwrwx  13 larry  staff   4.0K Jan 17 17:37 myexport

All folders within myexport are drwxrwrwx as well.

It's been an ongoing battle to get NFS and OSX working together but when it works it works flawlessly and fast.
AFP is on the way out, and Apple is sticking with Samba, which has always been a pain in my neck, whether the clients are OSX or Windows, there was always some sort of issue.


Copying 84 gigabyte file via USB results in duplicate file warning and case sensitive fail where no duplicate exists

OP's solution:

  in the end opened up my FTP client and transferred the file via my local ethernet. It worked!

  I would highly recommend that you perform a total system backup using Carbon Copy Cloner.

  Carbon Copy Cloner does support restoring to a case-insensitive system from a case-sensitive one - see this.

https://superuser.com/a/380358/1038202

  SuperDuper is the best way to clone drives in OS X. You can rename the destination drive in Finder

https://superuser.com/a/20779/1038202
There's also a script on Github, which claims to

  Resolve all case-sensitivity naming conflicts
  Make a fresh TimeMachine backup
  Flip the backups's case-sensitivity flag
  Restore from the manipulated backup

iOS 14 - Application does not have an entry in the device settings

Normally you can get the apps to appear by simply quitting and reopening the Settings app.
On the iPad Air you can do that by double-clicking the Home button to get the app switch. Swipe upwards on the Settings app in order to quit it.
After opening the Settings app again, the list should be refreshed.
If this doesn't help, ensure that you can actually start the apps in question. I.e. tap them to run them.


How to transfer a file from iPhone to computer when there is no Internet?

If you can transfer the document to a general-purpose app that "knows" about files (like GoodReader, Air Sharing, or iBooks), you should be able to access it from the file-handling dialog from within iTunes.

Most computers can create an ad-hoc WiFi network; using this, you'd use a network-sharing app (like Air Sharing) to mount a disk from your iPhone and transfer the files to your computer.


You may need to tell the configure of ccid where libusb can be found. Install libusb by downloading it and then running

./configure
make
sudo make

Then do the following for ccid:

.configure LIBUSB_CFLAGS=-I/usr/local/include/libusb-1.0 LIBUSB_LIBS="-L/usr/local/lib -lusb-1.0"

(check the version number first).


Prevent artwork synch in iTunes for iPhone

You can do a bit of a clumsy workaround.

First you have to select all your songs on iTunes, right-click and select Clear Downloaded Artwork. Than you can sync your library with your iPhone. After that you can download your artworks again. So you have your artworks on your computer, but not on your iPhone.


USB intermittently not working - requires restart - what to try next?

The first step in diagnosing the problem is to create a user account and see if it happens for that user. If it still happens, it's probably hardware but could still be software. To verify it is not, then remove any software that installs Kernel extensions (VMWare does this, as well as USBOverdrive, SteerMouse, etc…) and see if it still happens.

The fastest route is probably taking it to the genius bar, even if the machine is out of warranty. They have tools that aren't released to the public that go much deeper than any commercially available hardware diagnostics software.


Scrobble to last.fm with iTunes home sharing

It can be done, using the following steps:

In iTunes, go to Preferences > Sharing Preferences. There is an option there called 'Home sharing computers and devices update play counts'. Turn that on.
After you've listened to some music, open the last.fm Scrobbler application on your computer, and it should prompt you to scrobble what you've just listened to.

Works for me - I'm using iTunes 11 on a Mac.


This is absolutely 100% perfectly fine!

My MBP temp is regularly between 66 and 81 degrees, and my fans are regularly at 6200 RPM when my CPU usage is high.

Also, this resource (which can be filtered) clearly shows that 50°C - 60°C is nothing to worry about.
