using {option,control,shift} down doesn't work; use using {option down, control down, shift down} instead.
BTW, I should probably describe how I found this problem, since it's a very general and useful troubleshooting technique. I don't know AppleScript syntax well enough to spot this as a problem, but I do know how to isolate a problem: by removing parts of the code (or replacing them with placeholders if necessary), and seeing if the problem goes away. By seeing which bits of code remove the problem, I can isolate where the specific problem is.
This technique is the basis of the "divide and conquer" method described here for creating a minimal, reproducible example of a problem before posting it here. This is an extremely useful process to go through before posting, both because it'll reduce the amount of irrelevant stuff people here have to look through to find the problem, and also because there's a good chance you'll spot the problem yourself once it's isolated out.
In this case, I used the opposite technique: rather than trying to remove everything except the problem, I tried to remove only the problem. That is, I removed sections of code, and if the problem remained I put that section back and tried removing something else instead. But if removing a section did remove the problem, I'd put it back and then try removing just a smaller piece of it.
So, the first thing I did was remove most of the contents of the tell application "Safari" ... end tell section (leaving just activate, so it wouldn't complain about an empty section), hit the Compile button, and got no error. So I put it back (Command-Z to undo), and removed just the repeat 100 times ... end repeat section. Compile, still get the error. Ok, put that back... and there's one other line that looks different from most of the others. So I removed the line with {option,control,shift}, Compiled, error gone!
So at that point I knew where the error was coming from, and it was just a matter of trying variations on the syntax until I found one that worked.


Yes.  When you create (or Edit) an event, you can click on the Start time, enter it, and then click on the End time, and enter that as well.  You can also make the event  All-Day.  These options are in the same window used to create the event.

To start the process, just double-click or right-click on the day of the event.  Your options will immediately be apparent.  You Title/Name the event,, enter the location now, later, or never.  If the window closes before you finish, double-click the event to edit for the times, notes etc.  Right-click will get you the same options.  Get Info on the event will also work for editing.


How to add custom header when composing mails?

UserHeaders

For Apple's Mail.app, you can use the default UserHeaders to provide a dictionary of key value pairs to insert into the headers of outgoing e-mails.

To set the Disposition-Notification-To header to email@address the following command can be used:

 defaults write ~/Library/Containers/com.apple.mail/Data/Library/Preferences/com.apple.mail.plist UserHeaders '{"Disposition-Notification-To" = "email@address"; }'

On macOS 10.14, you will need to grant Terminal.app the Full Disk Access right in System Preferences.app > Privacy & Security before issuing the above command.

See Mail Receipt for an example of this default and notes about its application.


iPhone SE touch recognition and battery problem

iOS 12 should bring better performance and battery life, not make it worse.

Since you have just recently bought the device, you should tell whoever sold you the device that it has these defects and request to exchange/return the device for a new one. You should probably hurry before you run out of time to return it.


Removed app is still available - how to remove it?

If you are trashing an app manually, then you have to delete it's supporting files. Those could be in Application Support, Contextual Menu Items, Preferences, Receipts etc folders.

Use apps like AppZapper to uninstall apps completely with all the related files. It's a paid app, but it works very well.


To get a free C/C++ compiler you have to download Xcode. It includes two C compilers; clang (the compiler Apple currently supports) and an old version of gcc. (Note current versions of Xcode >=5 I think only have clang) Make sure you install the command line tools if you want to use the compilers from outside Xcode. (These command line tools also seem to be available from Apple's developer site if you register but I would get them via Xcode unless you have a very good reason and understand the difference).

All other compilers I know of use one of these two compilers and their binary tools to set themselves up. (e.g. package management systems like macports, fink and homebrew need these command line tools to run parts of their infrastructure as well as to compiler their ports - however these package managers include ports of  other c compilers e.g. newer versions of gcc.)

IDEs like Eclipse use these command line compilers to do the building of programs.

There are some commercial compilers like Intel's C++ compiler but I do not know if these require Xcode or are C compilers.

How to uninstall not App Store apps using Launchpad?

It is possible but it's a bit "hacky".

Open your Applications Directory in Finder
Find an app the was installed from the Appstore.
Right click on the .app and select Show Package Contents.
Copy this directory (_MASReceipt).

Now repeat the above steps or write a script to place that directory in
all of the non Appstore apps by selecting Show Package Contents and pasting the copied directory.

How to connect a USB-C-based MacBook to a Thunderbolt display?

As @Kevin McKenzie already said, and just to expand on it.

At present there is no adapter for the USB-C to Thunderbolt.

Here is quote from http://9to5mac.com/2015/03/09/apples-12-macbook-gets-new-usb-c-power-vga-usb-and-hdmi-adapters/

  Thunderbolt Gen 1 and 2 don’t support USB 3.1, Type C or even 3.0 for
  that matter. An adapter wouldn’t have fixed this problem. However,
  Apple is releasing Thunderbolt 3 later in 2015. It’s not ready yet,
  because it’s developed with Intel and now Gen 3’s functionality is
  tied to Skylake chips – which will replace Broadwell shortly. I know.
  You’re thinking “But Broadwell just came out!” That’s true, but only
  because of delays. Now, you may wonder how a new MacBook without a
  Thunderbolt port or a Skylake chip will support a Thunderbolt Display.

  Well, in short it won’t. That is unless Apple releases a firmware
  update for their Thunderbolt cables. Which they won’t. So it probably
  won’t support it. Considering the last time they updated it, I think
  we’ll see an update at WWDC, with a USB C port on the display itself.


dnsmasq not working oh Mac OS High Sierra

tl;dr make sure you start dnsmasq as root.

To diagnose this problem, I used Console.app, and searched for dnsmasq.

My first problem revealed in the logs:

failed to create listening socket for 127.0.0.1: Address already in use
FAILED to start up

To fix this, make sure dnsmasq is stopped:

brew services stop dnsmasq

then use Activity Monitor.app to kill any old dnsmasq processes.

After the socket conflict was removed, I attempted to start dnsmasq again:

brew services start dnsmasq # does not work

and now the logs in Console.app show

failed to create listening socket for 127.0.0.1: Permission denied
FAILED to start up

To fix this, I restarted the service as root:

brew services stop dnsmasq
sudo brew services start dnsmasq

Now

curl foo.test

works!

After this journey, I revisited all those dnsmasq help articles I read. The sudo was there all along and I skimmed over it.  I'm posting this for the next person that forgets to start dnsmasq as root.

Bootcamp cannot be selected through option key after patitioning using recovery

The error message appears when there is no partition flagged as active in the Master Boot Record (MBR) partition table. The sudo fdisk /dev/disk0 command prints out the contents of the MBR table. The active partition is indicated by an * character. This is absent in your posted output. If the fourth partition contains Windows, then you can use the fdisk command to flag the fourth partition as active. If the fifth partition contains windows, then you would need to first put the fifth partition in the MBR. Most users opt to download and use the gdisk command do this.
I should warn you that if you fix this problem, there still exists the possibility that Windows may interpret your repartitioning actions as an attempt to illegally clone Windows to a new machine. If this happens, then the easiest solution to this problem would be to rebuild the BCD.
The commands below can be entered to put the fifth partition back in the MBR partition table and make the partition active. Hopefully Windows will boot. You probably will need to enter the commands while booted to OS X Recovery. The sudo may not be needed. Note also that the fdisk command is interactive.
sudo fdisk -e /dev/disk0
e 4
7
n
332148736
156248064
f 4
q

If entered correctly, then the MBR partition table should appear as shown below.

Macbook Pro Display - Green Flicker only when Photoshop etc is open

Sounds like the beginnings of a GPU failure - there is an active repair program that runs through the end of the year for the 2011 MBP, so get your machine to the Apple Genius Bar and ask for a VST test.  Good luck!

https://www.apple.com/support/macbookpro-videoissues/


Power Mac G5 2005 boots with flashing question mark

More than likely the hard drive in the upper bay is failing.

Failing hard drives often make loud clicking sounds.  It's not as common, but is far from uncommon to hear beep error tones from failing hard drives as well.
The gray screen with an flashing folder icon occurs when the Mac cannot find a valid OS X system to boot to.  This can be a result of a badly corrupted operating system (often resulting from impending hard drive failure), a failed hard drive or a new unformatted hard drive.
The AHT error code more than likely stands for SATA Function or something similar, and since it references "upper" I would interpret that as the upper of two items.  Depending on your G5 PowerMac you might have dual processors but these are usually referred to as A or B and would throw a CPU error rather than STF.  Since there are two drive bays, where the two SATA disks are aligned vertically, I would interpret the error as meaning the upper disk is having the problem.

To diagnose the issue you could try this...

Power your Mac on while holding command+V (Apple + V if an older keyboard).
Assuming the disk isn't completely failed this should boot the Mac in verbose mode, where you can read what is occurring as the Mac is attempting to boot.
I would be on the lookout for "Disk I/O" errors, these will indicate a hardware failure with the hard drive itself.  If the Mac doesn't boot to verbose mode and instead only shows the flashing folder icon again then I would again assume a hardware failure.  With AHT (the diagnostic you ran) already reporting an error this is likely the scenario.

More than likely replacing the startup disk WILL fix the issue.  Most any 3.5" SATA disk will work although I would keep it relatively small (less than 250GB) as some of the earlier PowerMac G5s had firmware limitations on hard drive capacity.  You will need to partition/format the disk using "Apple Partition Map" and re-install Mac OS X.

Hope that helps!


It depends. If your machine was password protected, you might be out of luck. If not, there are a few possibilities.

If you have SSH enabled that might be an option. Also, if you had any remote access programs installed, like TeamViewer or LogMeIn, you have a chance to find it, assuming it's connected to the internet.

Regardless, I suggest contacting Apple and telling them the serial number of the machine and that it was stolen. If it's brought in for service, you might be able to get it back. (Although Apple has no official policy on this, it doesn't hurt to tell them. I contacted them when my iMac was stolen. Like I said, not much help, but it's better than nothing.)

PS: Check this out. You might find it inspiring at least.


Is there a way to add Touch bar controls when using spotlight search?

I use Spotlight as a calculator all the time, without specifically pressing buttons, but simply typing my equation into Spotlight:

It's smart enough to realise what you're doing, and pressing {Enter} will load the Calculator app with your results, so you can continue / copy&paste.


Is there any way to recover your apple ID if you forget both your password and your recovery key?

This happened to me! I created a new Apple ID using my device (because it was the only way to create an Apple ID without having to have a non-iCloud email account associated with it), didn't realise that Find My iPhone was switched on, and then promptly forgot both the password and the security questions/answers for the account. I could still use the device, but I was unable to switch off Find My iPhone or erase the device. So I force-restored the device, but was then presented with the activation lock.

Apple helped me reset the activation lock because I was able to prove that I purchased the device. Your receipt contains identifying information such as the Serial Number and IMEI number, so when I provided Apple with this receipt, they were able to remove the activation lock for me.

But I never recovered the Apple ID itself.


exporting numbers 09 to excel with photos in spreadsheet

There are two ways that an image can exist in Numbers.app, to my knowledge:

Within a cell (in a table) - here, the cell has an "Image Fill";
"On top of" the table.

Excel doesn't support option 1.

If you drag an image file into a Numbers spreadsheet, you'll get option 1: the image will be inserted within a cell.

Instead, in Numbers, use the Insert > Choose… menu and select the image file.  You'll then get option 2, which is correctly exported to .xls format in my limited testing.

Mavericks: Second Apple Thunderbolt Monitor Intermittently Ignored

Similar issue here. I have a 15" Macbook (early 2011) and a single thunderbolt display. Often, when the mac wakes from sleep my thunderbolt display does not connect.

I found that unplugging the thunderbolt cable and reconnecting it gets the display recognized again. Not ideal but at least better than a reboot.


Connection refused: MongoDB 4.2 on Mac OS

How to fill down in Numbers without dragging?

Found a way.

Select the column
Deselect the header row (Cmd click on the header
row cell)
Table Menu > Autofill Cells > Autofill Down

This will not infer a pattern. (ex 1,2,3 it will just copy down 1,1,1)

If you’re expect it to interpolate, you have to click-drag.

It will fill down formulas and they will be correct.


How to add a 2nd monitor to Macbook Air (mid-2012)

100% yes. Just keep in mind that you can't exceed  a certain resolution (I think it's 4K). Also, buy an hdmi dongle that is compatible (some cheap generic ones offer very poor sound and video quality)

You will be able to use as many apps as you'd like on both monitors simultaneously, and some programs (e.g. Photoshop) even allow you to spread them across multiple monitors.


Edit Content of IPSW file to install older baseband firmware

Downgrading the baseband hasn't been possible to do on the iPhone 4 since iOS 4.0.x. Even if you had been preserving the baseband, the tool to do this with (sn0wbreeze) hasn't been updated since iOS 6, so you wouldn't be able to do it anyways. And to answer your question directly, no, it's not possible to downgrade it by injecting the older firmware into the IPSW. It kind-of used to work that way, but things have changed drastically since iOS 4 (and you needed a bootrom exploit to do it anyways on iOS 4).


After doing a hardware reset as you said in your question, I think there's no option left but a broken antenna.

It's worth visiting Apple OR even better a local repair-man because if you get it repaired at Apple you pay at least 2 times as much.

Since it's a 4s you could consider looking around for a good deal for a new 5 or even 5s.


Charger that lets you use an iPod Touch while charging?

I have an Apple USB Power Adapter that came with my iPhone and in no way does it prevent me from using any feature of my device while charging. I can play audio out of the built-in speaker as well as through the headphone jack without issue. I'm not sure what wall charger you have, but if it's the Apple USB Power Adapter you should try to return it or exchange it as yours is likely defective.


How do I add a line from the end of a sentence to the edge of the paper in Pages?

The easy way to do this is to select the first line - change the text style to be underline and add tabs after the “e” in experience.

This way, the underline goes as far right as you please.

Adding a horizontal line is fine as well if you can accept a line break under the heading and before the list starts.

Both of these work on iOS pages, web app pages as well.


You may want to manually inspect the .Trash folder in your home directory and remove any files found inside. I've seen some instances where things were not completely removed.

In Terminal:

rm -rf ~/.Trash/*

(Original answer)

Go and grab the free OmniDiskSweeper app and run it.

It will help you see both the visible and hidden files on your system. Only remove those which you know that you do not need. You can easily corrupt the OS if you start moving system files without being certain what you are moving. Your caches may be taking up a lot of room somewhere.

OmniDiskSweeper will help you find and eliminate files. If you have an external drive you could also just move some of the files over using Finder. Your disk seems incredibly small as it stands (50GB?).

There are hidden files elsewhere on your system. Usually under your home directory. If you are familiar with Terminal, you could try to change to the home directory and review the hidden folders.

cd ~
ls .*

If you have an external USB you might want to use the symbolic link method to move the hidden folders and replace them with a symbolic link in that location:

mv /path/to/original/foldername /Volumes/TargetDisk/path/to/moved/foldername
ln -s /Volumes/TargetDisk/path/to/moved/foldername foldername

Where "foldername" is the name of the folder you want to move and make a symbolic link. Only attempt this is you are very comfortable with Terminal. Otherwise just use OmniDiskSweeper.

Good Luck.


Go to System Preferences -> Speech -> Select the "Text to Speech" tab, then choose the voice you want from the "System Voice" drop down.

Can I use iPad/Airport/Mac Mini as a development network?

A new Mini is most likely 'enough' computer, but you also have options as to which OS you run on it.

Do you intend to run your development server on OSX?  You could also run Windows or Linux either natively or virtually.  Given the myriad options, I'm sure it's possible to do what you're looking to do.

Your AirPort will allow communication between the Windows PC and the Mini.

As far as the iPad goes, there's and app for that.  I've personally used the Teamviewer app and the RealVNC app.  Both have served me well.


App for playing multiple tracks from different sources simultaneously

Audio playback is handled as a background task in iOS. Only one app is allowed to playback background audio in iOS at a time.

Music playing apps usually programmed to continue playback even when in background (i.e. while you are using some other app, such as Safari). As you are looking to play music via two different apps, it will not be possible if both of them are programmed to support background audio playback mode.

However, when one of the apps plays back music while not supporting background mode (such as a game app), it will be possible to playback music simultaneously from two apps, i.e. one supporting playback in background while the other is frontmost.


Yes, use iMovie HD. I switched back and used the ADVC with iMovie HD, and it worked fine.  iMovie 8.0.6?  Seemed like it was importing the whole time, but: where was the file? OY. Glad I kept iMovie HD.

Standard Disclaimer: Since it's jailbroken, neither I or Apple can guarantee full/any support.


Is it possible to increase price of an App?

You can set and change your price at any time. You can set price changes immediately, or scheduled ahead of time.

You can choose which price from a range of tiers provided by Apple.
eg. 99c, 1.99, 4.99, etc.

You can't yourself choose 49c or $2.68, or any arbitrary value.

See:

Changing Product Pricing

Scheduling Price Tier Changes

Pricing Tier Matrix


Had you previously disassembled or repaired the phone prior to it stopping charging? Why not take it into an Apple Store to get them to fix it?

Assuming you've not made a mistake in your repairs between the battery and the dock connector, yes, it's probably the logic board.


Registering as an Apple Developer as a sole proprietor using a dba (doing business as)

Contact Apple

You should contact Apple iTunes directly about this question. The answer will depend on your geographic region and exact legal status.

Business Name

Apple appear to enforce the use of the registered business name. For sole traders and similar business structures, this means your personal name.

See Does app store display sole trader's name and home address? for a related Apple Developer Forum discussion:

  The only way to not display your name is if you have a company/LLC, in which case gather the related documentation and contact Apple via the Contact Us tree found in iTunes Connect.


Flash Local Shared Object storage security issue?

There seems to be a usernamespace problem if you want to open OS X apps inside tmux.

To fix that install with Homebrew:

brew install reattach-to-user-namespace

and put this inside your ~/.tmux.conf for the Bash shell:

set-option -g default-command "which reattach-to-user-namespace > /dev/null && reattach-to-user-namespace -l /bin/bash || /bin/bash"

after that you should be able to open files also in tmux.

To restore some functionality, go to System Preferences > Trackpad, and tick the box next to "Tap to click".

It's possible this is a software or driver issue. However:

If the trackpad does not depress with a "click-clack" noise when you push the lower left or right corner, it's possible you have a hardware issue: Something is preventing it from moving internally. On a 2011 MacBook Pro this can be caused by:

• Battery swelling
• Improperly adjusted Trackpad screw (movement over time can cause the screw to rotate)
• Trackpad hardware failure

To diagnose the cause, inspect the bottom case of your MacBook Pro. Is the case swollen under the trackpad, either visibly or by touch? If so, your battery should be replaced immediately.

If the trackpad doesn't depress when pushed, it's most likely a stuck trackpad (screw adjustment) or a trackpad hardware failure.

Repairing Disk Permissions can sometimes solve input issues.

Go to Applications > Utilities > launch Disk Utility. From the First Aid tab, select your Hard Drive in the left field, then click the Verify Disk Permissions button. If you find errors, you will need to restart to repair them.

The AZERTY keyboard is the most common in France. '[' is shared with the '5' key and ']' is shared with the degrees symbol key to the right of '0'. The '[' or ']' characters appear when you use the AltGr key.

I would hate to be doing Objective C on a French keyboard!

Home and End depend on context in Windows. If the text is editable, home goes to the beginning of the line and End to the end of the line. The Mac does this with Command-Right Arrow (End) and Command-Left Arrow (Home).

When the document is not editable, Home goes to the beginning of the document and End to the end of the document in Windows. On a Mac, for Home you use Command-Up Arrow, and for End you use Command-Down Arrow.

There are a few things you could try to troubleshoot this - but you will need to be patient as troubleshooting is often a process of elimination and takes time.

For starters, I'd do a NVRAM and SMC reset (in that order). Before following the steps below, ensure you have no external hardware connected and that you're using the built-in keyboard.

Reset the NVRAM

Reset the NVRAM on your MBP as follows:

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

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

Reset the SMC

There's a couple of ways you can reset the SMC on your MBP, however I prefer the following steps:

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

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

If you're still having problems, the it's time to test your hardware with Apple Diagnostics.

Run Apple Diagnostics

Follow the steps below to run Apple Diagnostics:

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

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

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

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

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


Adding alias of an App or actual App onto the right side of Dock

The dock area on the right side of the line separator is reserved for recently used apps. You can go to System Preferences > Dock and tick Show recent applications in the Dock. However, note that it will only keep recent apps and is not customisable.


AirTag can’t be used to recover stolen item if thief has an iPhone?

AirTags are not marketed by Apple as an anti-theft solution. It is for lost items only (i.e. when you can't remember where you left your car keys in your home).
If an AirTag is stolen, the thieve can detect the tag (given that they have an iPhone running a sufficiently new version of iOS) and disable it. Indeed even if they haven't, the AirTag will after a time emit a sound when moved, alerting the thief to its presence. However, you will still be able to see its last known location in Find My.


Can the 2016 15-inch MacBook Pro (with Touch Bar) drive 4 external monitors?

The 2016 15" MacBook Pro will support up to four external displays.

You can have either of the following two options:

Up to two 5K displays
Up to four 4K displays

Specifically per the tech specs of the 2016 MacBook Pro:

  Simultaneously supports full native resolution on the built-in display
  at millions of colors and:

  Up to two displays with 5120-by-2880 resolution at 60Hz at over a
  billion colors Up to four displays with 4096-by-2304 resolution at
  60Hz at over a billion colors Thunderbolt 3 digital video output

  Native DisplayPort output over USB‑C VGA, HDMI, and Thunderbolt 2
  output supported using adapters (sold separately)

The 13" model will support up to 2 external displays either

One 5K display
Up to two 4K displays


I found out the keyword to look for is AuthenticationAllowed.

Here is an example of a bad login:

2017-03-27 14:58:52.616248-0500  localhost com.apple.AccountPolicyHelper[226]: (78.701.2) AuthenticationAllowed completed: record "testuser", result: Success (0).
2017-03-27 14:58:52.616578-0500  localhost opendirectoryd[78]: Verify password result: 5000
2017-03-27 14:58:52.616620-0500  localhost opendirectoryd[78]: ODRecordVerifyPassword failed with error 'Invalid credentials' (5000)

And this is a good login:

2017-03-27 15:02:33.444367-0500  localhost com.apple.AccountPolicyHelper[226]: (78.702.2) AuthenticationAllowed completed: record “otheruser", result: Success (0).
2017-03-27 15:02:33.444540-0500  localhost opendirectoryd[78]: ODRecordAuthenticationAllowed completed

You can find these by using the log show —style syslog -last 5m command. This will show the last 5 minutes of messages.


It would be great, IMO lack of tabs and bookmarking has always been a little bit of a failure for the iTunes store.
Now, unfortunately, the iTunes store is difficult for browsers to interpret, because it was written in a wacky XML format instead of a browser standard HTML.

About three years ago it emerged that a coder had written an app that decodes this XML into HTML, and therefore could be viewed in the browser etc.

This is the link for it, but unfortunately, for me anyway, it seems to be dead.

Apple released 'iTunes Preview,' where you can browse content, as a web based store with links over the iTunes, but I don't think this is quite what you were looking for.

This Apple support article, Non-responsive DNS server or invalid DNS configuration can cause long delay before webpages load, may help:

  DNS configuration

  This may indicate a non-responsive DNS server or an invalid DNS
  configuration. A DNS server converts a name to a numerical IP address,
  "www.apple.com" to "17.149.160.49", for example. You can connect to an
  IP address without any delay, because the need for DNS resolution is
  avoided. Here are four scenarios in which the symptom may occur:

  You have specified two or more DNS servers in the Network preference pane (possibly at the direction of a network administrator
  or your ISP), but the first server on the list has become
  non-responsive, or was entered incorrectly. The delay occurs while Mac
  OS X waits for the first server to respond, then it goes to the next
  server in your list.  Make sure the addresses are entered correctly.
  Changing the order of DNS addresses may improve performance. If your
  network administrator prefers that the primary server be used, you may
  wish to change back to the original order after the issue is resolved
  with the primary server.
  Your network may be configured to provide automatic discovery of DNS service, without needing to manually type the DNS server addresses
  at your computer. If you have manually typed a DNS address that is
  incorrect or out of date, your computer may wait for the incorrect
  address to respond (a "timeout") before succeeding at automatic
  discovery.
  You have not specified a DNS server, and automatic discovery of the service is not provided on your network. In this scenario, you can
  only connect via an IP address. Web pages do not load at all via a DNS
  name, such as is described in this article.

  How to resolve

  Check with your network administrator or Internet Service Provider
  (ISP) to make sure your DNS information is correct. If your ISP only
  provides you with one DNS address, consider requesting a second one
  for use in the event that the first becomes unavailable.

  Once you have the address(es), you can use these steps to change your
  DNS information. Note: After using these steps, some Internet
  applications may need to be quit and reopened to return to normal
  behavior.

  Mac OS X v10.5 or later:

  From the Apple menu, choose System Preferences.
  From the View menu, choose Network.
  Click the interface you use to connect to the Internet, such as AirPort or Built-in Ethernet.
  If you use Built-in Ethernet: Type your DNS address(es) in the DNS Server field. If you have more than one, separate them with a comma.
  If you use AirPort, click Advanced, then click the DNS tab. For each server, click the "+" button under DNS Servers and enter the
  address provided by your ISP or network admin. Click OK when done.
  Click Apply.

You can use builtin Time Machine application.
First - make a backup on Your external drive using TimeMachine.
Then on the new Mac use Migration Assistant.

Here is the link with detailed info: http://www.macworld.com/article/2066996/how-to-transfer-backups-from-time-machine-to-a-new-mac.html

  On the new iMac make sure that you have access to the drive where the Time Machine backup is stored and then launch Migration Assistant. It will notify you that it needs to quit all open applications. Allow it to do so.
  The first Migration Assistant screen will offer three options regarding data transfer. Select the first one, which reads From a Mac, Time Machine backup, or startup disk and click Continue.
  In the next screen choose the drive that holds your backup and then click Continue.


Is there a way to sync Lion's Reading List across two or more Macs?

Syncing between all macs, pcs and iOS devices will be possible when iCloud is released to the public along with iOS 5.


Is there an app for running Go code on an iPad?

As far as I am aware, unfortunately, there are no iOS apps for running Go. You could try to add a shortcut to https://play.golang.org to the homescreen; this effectively emulates the functionality of being able to type and compile Go code. However, needless to say, this requires an Internet connection and so is of limited use if you really need to edit "on-the-go" (no pun intended).

There are a plethora of developers who have created apps for large varieities of languages, but, as you acknowledge, Go is consistently omitted from their repertoires. If you search for a popular language, like Python, for example, then choose one of the apps for it and look at more by the same developer, there is usually a large range of associated apps, each dealing with its own programming language. In searching for Go apps, I repeated this process many times, and found apps for Lua, Groovy, Haskell and other not-so-mainstream (by which I mean less popular according to TIOBE) languages, but no Go. My search however, was by no means exhaustive, and this seems to be a much better avenue than simply using the built-in "search" feature on the App Store, so, if you are really desperate for offline functionality, I would consider carrying on along these lines (if you have not done so already).

If you can wait to compile your code until you are online (on play.golang.org), then there are several text editors with Go syntax support (Coda for iOS is a personal favourite).


How to quickly remove all useless iOS applications on my Mac?

You could right click on any app in iTunes Apps section, click Show in Finder, then sort by Date Modified and erase all those that haven't been updated in a long time and that you don't use. Be careful because one of your preferred app might not have been updated recently.


How to make Apple Maps work for transit directions and finding businesses:

I've gotten myself to a pretty good solution, so I thought I'd share.  Mine is NYC-based, but the POI solution will work almost anywhere, and the transit one should work in most major cities in the US (which are the only places transit's likely to be a must-have.)
Here's the really short version:
Download Where To? for  business listings ($2.99) and Embark Transit for subway directions (free, if they cover your city).
Both plug directly into Apple Maps app, and plug its two major gaps.
How to find businesses and points of interest:
Dowload Where To? on your iPhone.
Yes, it costs $2.99, and there should be good, free solution, but there isn't, and it works.   Where to? will let you just click from categories to find common business types near you without typing:

And, if you're looking for something specific, you can search, and its database is not just limited to chains and common stores (I tested it by searching for B&H, a well known, but single-instance NYC electronics specialty store.)
You can see the results in a list, or on a map.  Importantly, once you find somewhere you want to go, you can click on a little "right curve ahead" icon (it's also the app's icon) to get directions there, using either apple maps (which can then provide turn-by-turn directions since Where To filled the gap of finding the business), or using other apps you may have installed (MotionX, TeleNav, etc.)
There's also a 0.99 in-app purchase that lets you put locations on a camera picture, augmented reality style.   This probably more cute than useful.  It might be functional in dense cities if the compass worked better in them, but you can try it free to see if you like it first, so there's not much harm.
How to get transit directions:
Dowload Embark Transit on your iPhone.
Embark is free, pretty solid, and has apps that cover:

Boston
Chicago
Philadelphia
London
NYC
Washington, DC
San Francisco
Caltrain
NJ Transit
Metra
LIRR

It's got the full map of the system, but can also route the best path between two addresses and give you step by step directions of what station to walk to, where to transfer, etc.

And it works underground, as the data is stored locally. It doesn't cover every city, and it's not good at finding much without an address (like business names), but because it plugs into maps, and we now have a good way to get POIs there using embark, that's not a big deal.
Here's how to use Embark (or any 3rd-party transit app) from maps:

Install the app on your phone.
In Apple maps, click the "right turn" icon that goes to the directions screen - it's in the upper left corner of the app.
On the top of the directions screen, click the "bus icon"
Enter your Start and End (if they didn't pre-fill), and click "route"
You'll get the choice to use any installed transit app - in this case, it'll show you Embark, and if you click it, it'll open with that route pre-filled.

Yes, it's all a little more kludgey than it has to be.  But it works.

How long does it take to get used to the keyboard of the MacBook 12"?

If you can, go to your local Best Buy or Apple Store and check it out. I've only used one at Best Buy, but I think that I'd get used to it pretty quickly. Everyone is different, so YMMV. Just make sure you can return it if you just can't get used to it.


Chinese and Japanese characters are not shown properly on iOS

If you are talking about the form of the characters not being correct, so you are seeing the Korean character variants instead of the Chinese ones, these are in fact by default determined by which language is highest on the list in Settings > General > Language.  You would have to make Chinese higher than Korean in that list to get the Chinese forms displayed.

Below are some images of those characters Japanese, Chinese, and Korean forms (Korean at the bottom).

While you may be seeing Korean forms on your device, people you send text to will see the forms dictated by the settings on their own machine.  So a recipient of your email or text who is using a Chinese system will see the Chinese forms.

Of course if you are using an app where you can choose the font independently of the system, such as Pages, then you can make sure you choose a Chinese or Japanese font instead of a Korean one to get the forms you want.


It's unlikely that the pixels have died, but the edge connector of the screen may have become dislodged or damaged, or it could be that the connection to the logic board could be loose.

You can try following this ifixit guide to see if taking it apart and reassembling it will restore any bad connections that dropping it may have caused.

If that doesn't work, you can just replace the display, as on pre iPhone 4 models the screen/digitiser and display are separate components, so if that's the only damaged component then it should fix the problem.

How can I change my Mac OS X Services to all be in english?

This problem seems to crop up occasionally, and I haven't heard a definitive solution outside of the standard troubleshooting routines: determine if the problem is a software setting by creating a new user account, rebuild permissions, and so on.

Beyond the basics, there are two solutions that might help. First, in this thread over at the Apple discussion forums, someone has a similar problem and is able to resolve it by removing some spurious login items, then logging out and logging back in. It's worth looking at your login items suspiciously.

Second, you might try to change the system language to something new, like French. Log out and back in, then change back to English. It may be that you have some wonky settings left over from an old program, and that switching away from English and back re-aligns everything.


Fusion installing Mavericks this item is temporary unavailable

The only 'official' way to get 10.9.x [which would actually be 10.9.5] is to have previously 'bought' it - it would then be in your previous purchases list on the App Store & could be re-downloaded.

Alternatively, if that was the OS that was on the machine when new you can get it via Internet Recovery.

Otherwise, the only OS available to download will be Yosemite.


How to play a sound from the command line AND direct the output

If you are looking for your computer to play sounds or words you can use the "say" command on the terminal. Just type

and the computer responds with dog over whatever speakers you have chosen from the Sound selection under system preferences. Go to system preferences and choose the Sound icon. When that opens you can select options for what plays the sound on your computer. One option is the internal speakers.


Safari automatically appends .txt extension to .ino files

It seems that this is a server issue. And one can't solve the issue by changing safari settings. The answers to the same question I found are in the below.

iMeowbot user in macrumors says that:

  "This filename modification stuff isn't something that Apple made up,
  it comes straight out of RFC 2183 (see "2.3 The Filename Parameter"
  and "5. Security Considerations"). While that RFC talks about
  "messages" and "mail" it applies equally to the Web, as HTTP employs
  MIME.

  OS X and Safari have no way to read the mind of the server operator,
  and cannot tell if a mismatched media type and filename are accidental
  or intentional. So, they follow the standard.

  Recent Safari versions add additional checks, such as that annoying
  prompt for when something appears to contain an executable file. It's
  all part of the same healthy paranoia that helps ensure that the end
  user knows exactly what a remote server is attempting to send."

http://forums.macrumors.com/threads/safari-adding-txt-to-a-m4v-download.167086/

TETENAL user in macnn says that:

  "AFAIK the Apache server software comes with a preset of
  extension->MIME-type assignments. If a file with an unknown extension
  (like .dmg) is served with the MIME-type text as a fallback, Safari
  adds a .txt extension. This behavior is arguably correct. The server
  tells Safari it is serving a text-file, and a text file needs a .txt
  extension on Mac to be opened with a text editor. So Safari adds one.
  Other browsers ignore the server, which is a short term benefit for
  the user, but in the long run a) makes the server admin not notice the
  mistake and b) prevents the server admin to use this feature whenever
  he intentionally wants to (as opposed to unintentionally doesn't care
  as usually).

  Anyway, to fix this you can create a file .htaccess to the respective
  folder and correctly define the missing MIME-types by adding AddType
  application/octet-stream .dmg or AddType application/x-stuffit .sit
  and AddType application/x-stuffit .sitx etc."

How can I set a consistent font for sent messages in Apple Mail Mojave?

People who send plain text mails are heroes to me. There’s no downside there since it respects everyone including screen readers, people who have a font and size preference, etc...

There is a real cost to rtf bloat and html and you are seeing some of that pain here.  My solution is to eschew bu to know some people look down on that as plain text can be rendered horribly as well by some Mail clients.

Sadly, you have to read the room for your intended audience and choose an authoring tool that is copacetic. A third party mail app might be needed if no one has a style tweak that lets you keep the styling features you know you need to communicate effectively. Outlook on Mac does a decent job of hiding that the mail came from Apple if you have the desire to try that.


Dual Thunderbolt displays with a Mac running Windows under Boot Camp?

Unfortunately, as of now, you are unable to (I'm assuming that this is what you mean) daisy-chain two or more Thunderbolt displays (natively) into your Mac. I'm unsure if it's Apple to blame, Microsoft, or both. Wait until Windows PCs start receiving Thunderbolt (Microsoft should update the drivers by then) and try again. If that's not it, then it's probably Apple's fault and there is nothing that you can do now until Apple updates the Boot Camp drivers so that it can support this.


On OS X, what files are excluded by rule from a Time Machine backup?

There's a built-in list of exclusions stored in /System/Library/CoreServices/backupd.bundle/Contents/Resources/StdExclusions.plist. It's a bit too long to paste here comfortably, so I've posted a copy StdExclusions.plist (10.7.1) on Pastebin. There also is StdExclusions.plist (10.6.8 Server) on Pastebin.

Some of the more obvious user file exclusions are Trash, Document revisions and MobileBackups from the local Time Machine store are all excluded. The rest of the exclusions are for system things like caches and databases that exist to index other files where the system can regenerate these databases after a restore.

In addition, apps can use a file's metadata to exclude a file from backups. You can view this list of files by running the command:

sudo mdfind "com_apple_backup_excludeItem = 'com.apple.backupd'"

On my system this outputs the following:

As you can see, there are a few files here which various apps have told Time Machine not to bother with. Internally, this works by changing the extended attribute  com.apple.metadata:com_apple_backup_excludeItem.

Furthermore, on Lion, the tmutil command allows you to query, set, and delete file exclusions from the command line:

tmutil isexcluded _item_ will determine if the volume, directory or file is currently excluded.
tmutil addexclusion _item_ sets an exclusion rule so that the item (even if moved to a new location or renamed) will be excluded from future backups.
tmutil addexclusion -p _item_ sets an exclusion rule so that the item path is excluded. This remains unchanged so if the file moves it will be backed up if not at this exact path and also will prevent backing up a file if it comes back in the same location as the rule specifies.
tmutil removeexclusion _item_ removed either type of exclusion rule as appropriate.


How to disable Time Machine for an external hard drive

Go to Time Machine preferences, Ctrl-click on the drive you want to disable, you get a fold out menu with the option to disable the drive.


Lightroom catalog on external hard drive not readable

You could download a NTFS driver to read the catalog.

What you need to do is to create another partition on your Mac, and install Mavericks on it:

On your El Capitan partition, open Disk Utility (in Utilities) and select the physical hard drive in your Mac. It should be titled "APPLE HDD ... MEDIA" or something similar:
Click "Partition" and click the "+" sign at the bottom of the pie-chart hard drive. Select how big you want the new partition to be and give it a name:

Make sure the format is "OS X Extended (Journaled)" and click "Apply". It may take a few minutes to create your new partition.
Next, you will need to obtain a copy of the OS X Mavericks installer. If you have previously downloaded it, you can redownload it from the "Purchased" page in the Mac App Store, you could download it from a friend's computer (if he has purchased OS X Mavericks), or if you are on a paid Apple developer account subscription you could download a build on the ADC Downloads page.

If you have the Mavericks version of Internet Recovery, as you said you might, you can boot into it by holding Command-N at startup and clicking "Reinstall OS X Mavericks", and skip to step 10 and onwards. However, it is possible that with an OS X upgrade the process upgraded your version of Internet Recovery to the El Capitan version, for example.

Once you have the OS X Mavericks installer, you should copy it to a USB thumb drive. Copy the installer onto the thumb drive by dragging-and-dropping in the Finder.
Leave the USB drive in your computer with the Mavericks installer.
Shut down your Mac.
Hold the "option" key while turning your Mac on. You can release the "option" key until you see the Apple logo.
You will be presented with icons of your hard drives and external drives. Use the arrow keys to select the USB drive you made with the Mavericks installer on it and press the "Enter" key.
Go through the Mavericks installer process. When prompted for which disk you want to install Mavericks on, choose the new partition you created in Disk Utility.
The Mavericks installer will copy over all the files needed, and restart as part of the process.
You will be taken through initial setup of your "new computer" and when it is finished you will be using OS X Mavericks on a partition of the hard drive.
You can select which OS to boot into at startup by holding the "option" key while turning it on until you see the Apple logo. Use the arrow keys to select which partition.
You can set your default startup disk (i.e. what disk the computer automatically boots into without having to hold the "option" key) in System Preferences > Startup Disk.


Is it possible to speed up Spotlight indexing?

I doubt your process is CPU bound so you would need to bring faster storage to have it progress faster.

The pragmatic answer to this is:

just quit other programs that contend with IO
log out if you have sync products like Dropbox, Box, OneDrive or backup software that also scans for all file changes
be more selective - rebuild the index on a subset of the system if you need that portion to be done sooner
schedule your rebuilds for when you can walk away and not care how long it takes
if kernel_task is high - keep your machine cool (extra cool room, airflow, etc...) but that addresses CPU bottlenecks - not IO or data.

You can confirm my thinking in the Disk section of Activity Monitor and see what the reads in and out per second are and the bandwidth. Spotlight spins up multiple workers and is pretty sophisticated about doing parallel rebuilds, so it's unlikely you'll be able to twiddle with anything or cajole it to chew through all the content in all the files for all the data detectors in the system.

You can see these processes named mds, mdworker, mdwrite and variants of those core functions.

If you're logged out you'll need to ssh in and use top -u -s 10 or iostat 60 to see the activity level off or just check back on the visual indicator when you log back in.

Open your terminal (/Application/Utilities/Terminal.app) or use Spotlight to find the Terminal and type:

defaults write com.apple.QuickTimePlayerX NSQuitAlwaysKeepsWindows -bool false

That should stop QuickTime from saving the opened windows when you quit it.

If you want to revert the behavior, change the "false" to "true".


Access emails from Time Machine backups of old machine

I would try importing the old emails goto mails file menu-> import mailboxes
navigate to to the backup device, locate the old backup folder and navigate to users/{ussername}/library/mail/v2/mailboxes and import the mail


Memory/CPU usage comparison between two MacBook Pros

It is rather difficult to compare a fresh 'cold' new system with a 'warm' fully synchronized and updated one.  New Macs have a lot of catching up to do; iCloud service syncing and system patches being two of them.

On the other hand OSX - and every other OS really - chooses a healthy part of the available RAM (real, physical memory) above swapping to disk (virtual memory) for obvious reasons.  Having 8 more Gigs available probably decreased your swap file by a couple gigs.  Granted, swapping to those post-2013 SSD's is reasonably fast, but no (or less) swapping is always faster (and better for your battery).

Chances are high your increased RAM usage is part of those 2 reasons.


How do I deauthorize all computers on iTunes?

From this Apple Support article you can do it from your account.

  If you find you have reached 5 authorizations, you can reset your authorization count by clicking Deauthorize All in the Account Information screen.

The process works as follows

  Click iTunes Store in the menu on the left side of iTunes.
  If you're not signed in to the store, click the Account button, then enter your account name and password.
  Click the Account button again (your ID appears on the button), enter your password, and then click View Account.
  In the Account Information window, click Deauthorize All.

Also note the following:

  You may only use this feature once per year. The Deauthorize All button will not appear if you have fewer than 5 authorized computers, or if you have used this option within the last 12 months. If you need assistance on using this feature please contact iTunes Store support via email.


How to limit my Mac's exposure to malware?

Web browsing
The largest potential danger comes from the "Internet". My Mac is online most of its operating time and web browsers are among the most used applications on my Mac.
Therefore, the most important rules are:

surf the web carefully
don't just download any software you find

Browser choice
The browser choices, configurations and extensions offers various options to configure your security and privacy.
I like to use Chrome because it's known for having

strict sandboxing
updates itself, its extensions and flash plug-in automatically
open extension design

Safari's extension design is more restricted, causing the JavaScriptBlocker for Safari not to be as functional as similar extensions for Chrome or Firefox: e.g.  Web Bugs are not blocked.
Chrome is considered quite safe. It did not get exploited at the Pwn2Own hacking contest three years in a row (2009-2011). 2012 is the first year a team presented the use of a zero-day-exploit in Chrome.
The German Federal Office for Information Security (BSI) (similar to the NIST in the U.S.) recommends the use of Chrome because of its sandboxing technology and auto-updates.
Java
Chrome has disabled Java by default and asks you every time when it's required to run.
You can disable Java for Safari as well. You won't miss it most of the time:

Safari Preferences → Security → uncheck Enable Java
Open /Applications/Utilities/Java Preferences.app → uncheck Enable applet plug-in and Web Start applications

Other options

System Preferences → General →  check Automatically update safe downloads list

Open Safari downloads manually:

Safari Preferences → General → uncheck Open "safe" files after downloading

Flash and PDF viewer
Download Adobe flash only from the official website. However, you don't need to update it manually anymore. The latest Flash update for Mac adds auto-updates.
In Safari, you can use the ClickToFlash extension to manually allow flash to run in your browser.
You don't need to use Adobe's PDF viewer. Apples's preview works in Safari as well. You can remove the Adobe plug-in here:

/Library/Internet Plug-ins/AdobePDFViewer.plugin

Passwords
For creating passwords you can use the Password Assistant provided by OS X. Go to /Applications/Utilites/Keychain Access.app →  click the plus at the bottom left → click the key symbol.

Adblock lists
The Adblock and Adblock Plus extensions offer lists to improve your privacy and security.

http://adblockplus.org/en/subscriptions

The lists are named:

EasyPrivacy: privacy protection
Malware Domains: malware protection
Antisocial: blocks social integration.


iPhone 3GS lost and can’t use Find my iPhone

Two independent Big Sur installations on the same device

The answer is no.  Assume I install some software with admin rights on partition B. It can not be made sure, that the program installed on B has no possibility to ask the diskutil to remove entirely partition A.
Update
Maybe this explanation will make more sense to you. Originally with OS X, many problems could be fixed by booting to the OS X installation DVD. Security existed by storing the DVD somewhere safe. After Snow Leopard, Apple stopped issuing DVDs and instead opted for software downloads. A recovery volume was added to take the place of using the DVD to fix problems. The recovery volume contained limited functionality compared to a full OS X operating system. However, when booted to the recovery volume, changes could be made that are not normally possible when booted to OS X. This concept of recovery has been refined with each new release up to and including the release of macOS Big Sur. Along the way, Apple has taken many steps to prevent booting to recovery without first requiring user validation.
Installing a second Big Sur in a different partition creates in effect an extremely powerful version of recovery. So when booted to the second Big Sur, you are going to be able to mess with the first Big Sur, just as if you had booted to recovery. For example, SIP only applies to the partition of the currently booted Big Sur. The files in the other Big Sur are no longer protected by SIP. The same is true, if you were to install, then boot to Windows or Linux on your Mac.
The best way to protect your Mac is to only have on operation system installed. Once you install a second operating system,  you open up security vulnerabilities that Apple has not begun to address.


If you noticed a sudden slowdown then that points to an event of some sort that is likely pointed to an issue with the HDD (IMHO). Mac OS is very sensitive to issues with the speed of the disk, which is why it benefits so much from upgrading to an SSD. My recommendations?

Back up your vital data now.
Boot the system into recovery mode, run disk utility to repair the internal drive.

I'm betting that there has been some kind of disk error. The question remains whether or not it is a recoverable disk error. Unfortunately Disk Utility is not a comprehensive disk repair tool. There are others out there (my go to is DiskWarrior, but there are others) that can fix things that Disk Utility can't. If disk utility cant repair it you can try another utility or just replace the drive.


Minimum Resources to Download / Install OSX on MacBook Air

Usually nothing is required to install macOS except an active WiFi-Router connected to the Internet with DHCP enabled and its WiFi password.

After turning on the Mac and immediately pressing ⌘ cmdR the MacBook Air should boot to macOS Recovery over the Internet (earlier "Internet Recovery") (Apple Support: About macOS Recovery). You will be asked for a WiFi password.

If macOS Recovery over the Internet works you should see a spinning globe and depending on your Internet speed you will see the Recovery console sooner or later.

The console contains several tools including Disk Utility and Reinstall macOS

Disk Utility is required to partition and format the SSD. Later choose Reinstall macOS to install a new system.

If the above shortcut doesn't work you can try to press and hold ⌥ alt/option⌘ cmdR or ⇧ shift⌥ alt/option⌘ cmdR at startup.

The different boot and install options are outlined here: Learn more about these key combinations.

To improve user experience I would ask the future (unexperienced) user which system he/she/* would like to have and simply download and install it up to the configuration screen (like Apple does with new Macs).


Can't upgrade to 10.7.2 over a previous iCloud beta seed

While i haven't seen this problem with Lion, it was common with previous versions of OS X. The way to fix it was to download the Combo updater from Apple, and run the update. Apple provides this for Lion at http://support.apple.com/kb/DL1459, so i'd download that first, run it, and see if it fixes your problem.


Before you transfer your purchases, make sure that your MacBook is authorized with the same Apple ID account you used to make the purchases.
And for audio books, only one download is normally allowed per purchase. You can find the answer in Apple support center.

To transfer purchases from your device to a computer:

Connect your device to the computer. Wait for its icon to appear in iTunes.
Go to File > Devices.
If you're using iTunes for Windows and can't see the menu bar, learn how to turn on iTunes menus in Windows.
Choose Transfer Purchases from [device name].


macbook pro stuck in boot loop - recovery mode and safe mode not working

I was able to fix this by using a bootable Ubuntu usb to boot my system, and choosing the option for formatting the SSD. Then after installing Ubuntu I was able to use a bootable MacOS usb drive to reinstall MacOS Mojave successfully.
As mentioned above, absolutely nothing was working including the disk utility, internet recovery, or using a bootable MacOS USB drive. Everything was causing the system to freeze.


MacBook M1 Big Sur crashes every time when I open "About This Mac -> Storage -> Manage"

or you can select iOS device via side bar, select General tab and then Manage backups


Login problems with Automount and SMB shares

I have exactly the same problem. I follow the exact step described here: http://blog.grapii.com/2015/06/keep-network-drives-mounted-on-mac-os-x-using-autofs/

/Users/username/Desktop/Synology  auto_nas

Then I created the /etc/auto_nas with entry like the following

DSVideo -fstype=smbfs ://username:password@nas/video
DSPhoto -fstype=smbfs ://username:password@nas/picture

This creates a "Synology" folder on my Desktop with a DSVideo and DSPhoto subfolder which icon looks like a mounted disk as a subfolders.

It was working flawlessly with El Capitan MacBook Pro, however when I do the same with my iMac with Mojave 10.14.4, I experienced the same issue similar with yours in which my Mac would locked up just after login while loading Finder in which I could not launch any other applications.

I saw a silver lining after I read your post. It seems that adding nofail was able to prevent our Mac from being locked out if it fails to mount.

/-  auto_smb    -soft,noowners,nobrowse,rw,nofail

Now come to my suggestion for a possible solution. I have been reading forums for many many days. Can you try the following which might help you to mount your network drives?

Have you changed the ownership of your auto_smb to root access only?

sudo chmod 600 /etc/auto_smb

Have you followed this recommendation from Apple to disable a security feature so that you can connect without providing additional confirmation? https://support.apple.com/en-us/HT207112

sudo defaults write /Library/Preferences/com.apple.NetworkAuthorization AllowUnknownServers -bool YES

Alternatively, you can follow this instruction
https://gist.github.com/rudelm/7bcc905ab748ab9879ea

So instead of just using the following in your auto_smb:

/mount/mnt1 -fstype=smb ://<user>@<server>

You can add:

/mount/mnt1 -fstype=smbfs,soft,noowners,nosuid,rw ://username:password@<server>

Please let me know whether any of this works for you? Thanks.


How to tell total MacBook screen on time on battery?

I don't think that's something that Apple provides anywhere, however if you put in a little scripting work it's definitely doable. You can get the current brightness on the display with this command:

ioreg -l | awk '/ApplePanelRawBrightness/ {print $NF}'

A '0' result means the backlight is completely off. The upper limit depends on your specific hardware. You can get the highest possible number for your hardware with:

ioreg -l | awk '/AppleMaxBrightness/ {print $NF}'

You could set up a cron job to run that every minute, and record the result and current time, e.g. in a CSV file. You could then use a spreadsheet program to do the calculation. Or, you could use a higher level language like Python or Ruby to do the same thing and automate the calculation in your script. The latter would be my approach.

EDIT: I just noticed the 'on battery' part of the question - dunno how I managed to miss that. You can get a simple Yes or No answer to whether the AC adapter is connected using this command:

system_profiler SPPowerDataType |grep Connected | awk '{print $2}'


macOS: saving images from the clipboard using `pngpaste` is faded and white

Using these instead works fine:

    [[ "$name" =~ '\.png$' ]] || name+=.png

    osascript -e "tell application \"System Events\" to ¬

                                  {name:\"${name}\"})"
}
function jpgpaste() {
    local name="${1}"
    ensure-args name @MRET
    ensure isDarwin @MRET

    [[ "$name" =~ '\.jpg$' ]] || name+=.jpg

    osascript -e "tell application \"System Events\" to ¬
                  write (the clipboard as JPEG picture) to ¬

}

User account on iMac won't allow applications to open

One big change since El Capitan - Mail is now in V3
All the rest will be the same.

Try clearing the saved state, rebuilding & reindexing the database...

Clear Saved State

Switch to Finder,  Cmd ⌘   N  for a new window, then  Cmd ⌘   Shift ⇧   G  for Go To...
copy/paste ~/Library/Saved Application State/com.apple.mail.savedState then  Enter ⌅
This is an alias to the real location, so Right-click & Show Original
Delete the entire com.apple.mail.savedState folder.

Rebuild; Re-index

Source: How to fix Apple Mail by rebuilding and reindexing the Mailbox

  Step 1: Rebuild
  Rebuilding a Mailbox in Mail sounds daunting but it really isn't.

  Launch Mail, select one of your mailboxes and click on the Mailbox menu. At the bottom of the pane choose the Rebuild option. If you have a large mailbox, you can expect the process to take a few hours.
  You must repeat this step for each one of your Mailboxes.
  While the process takes place, you may experience system performance lag, as it can consume a lot of system resources and memory.

  Another caveat, if you use IMAP or Exchange with any of the accounts, the process will redownload every message from the server, so you'll use a lot of bandwidth.

  Now that you've completed these steps, work with Mail a little longer. If you are still having issues, or Mail fails to launch, you should try a manual reindex.

  Step 2: Re-index

  Manual reindexing of Mail messages is the only way to go if the  application has become so unresponsive it barely works at all, search is not functioning correctly or the app won't launch.

  Mail will automatically attempt to reindex your messages if it detects problems with the mailboxes, but sometimes a manual reindex is the best option. If you are still having problems with Mail after following step one, try manual reindexing.

  Quit Mail if it’s open.
  To get to your home Library folder, hold down the Option key, then in the Finder choose Go > Library.
  In ~/Library/Mail/V2/MailData, delete any file that begins with “Envelope Index,” such as Envelope Index or Envelope Index-shm. (Before you actually delete the files, it makes sense to copy them to a folder on your desktop.)
  Launch Mail and the app will build new Envelope Index files -- this can take a long time if there are numerous messages to go through.
  If everything seems to be working correctly, you can now delete the copies of the "Envelope Index" files from your desktop.

  In most cases, these two tips should solve most Mail problems


How can I prevent jittery video playback on High Sierra?

No, Apple did not deliberately slow down your Mac. (As for deliberately slowing down iPhones see this).

The reality is I see this sort of thing all the time, on both Macs and PCs, as well as other devices (e.g. smartphones, tablets, etc).

As time goes by the minimum requirements for software and hardware change, and the configuration of a particular system will have a big impact on how long it will continue to keep up with software changes etc.

Without knowing the full specs of your MacBook Pro (e.g. type of storage device, software, etc), it's nevertheless 8 years of age and obsolete.

As a result, this model will run Mac OS X El Capitan better than it's going to run macOS High Sierra. And, once you're running a particular version of an operating system, this will have much broader ramifications. It's not just the OS, but bundled software such as browsers that have greater requirements. Additionally, some 3rd party software/hardware will no longer work, or they'll have limitations, hence the need to regularly update/replace them as well.

In general, macOS High Sierra has greater requirements than El Capitan had, and although it still runs on older hardware such as yours, that doesn't mean all features will work on your machine. And while High Sierra can run with 2GB of physical RAM, its requirements are such that it's more RAM hungry than El Capitan was, hence placing a greater burden on your storage device for virtual memory purposes (having a fast SSD is going to handle this better than a traditional hard drive).

In other words, the problem you're experiencing is most likely the result of a scenario something like the following:

macOS High Sierra needs more memory to run (both in terms of RAM and graphics)
It therefore uses more of your physical 8GB RAM, thereby leaving less RAM available for other software etc
In response, macOS High Sierra makes more use of virtual memory to help manage the limited memory resources
This places a much greater burden on your storage drive which is having to deal with a lot more read/write operations
Your video playing software is potentially having to make more use of virtual memory and your storage drive is having to perform even more read/write operations as it has to deliver the video as well as everything else it's doing
End result: A stuttered playback experience.

Summary

The overall burden on your system from having High Sierra installed (along with all of its associated software etc) is much greater than having El Capitan installed. And, this overall burden will be more obvious with some functions than it will be with others. Unfortunately, playing video files is one such candidate for this.

If you had a 2011 MBP you might have been able to address this by increasing your RAM to 16GB, but that's not an option here. If you don't have an SSD already, then installing one will definitely help. If playing videos is the main purpose of this machine, then leaving it with El Capitan installed may be an option for you. Otherwise it's time to reconsider your setup as your MBP is no longer able to meet all of your needs.


Is it feasible to transition from external USB to NAS for data drive?

It all depends on a couple of things, not the least of which what, exactly, you define as "too slow." And that is going to be answerable only by trying it out. One of the other things it depends on is how fast your network is.

Modern networking is at the gigabit level, but it is still common to see routers and switches, especially those provided by your ISP to be 100mb (or 1/10th the speed of gigabit). Needless to say I would recommend you have gigabit networking. And if you are relying on your ISP-provided router for your network, perhaps you will need an inexpensive gigabit switch to connect all your computers with one port left over to then plug into your ISP-provided router.

Another consideration is what, exactly, you keep on the external drive. If it is your user profile I would say no. If it is your documents folder, probably.

Again it depends on your personal usage patterns and how much data you are pushing across the wire and how fast you need it to be.

I have a NAS. I use it for backup (Time Machine & Dropbox) and as a centralized location for music, TV & movies (Plex) but don't use it as a location for keeping files I am currently working on (Dropbox is there just as another backup location). But people work with documents (Word, Excel, etc.) across a GB network all the time, so it is completely doable.

But it depends heavily on your use case. So find a place with a liberal return policy (Costco?) and give it a try.


iPhone Proxy auto-configuration with username / password

HTTP GET logins have you include your username and password in the URL. For example, if you're using the fictional proxy that's located at www.an-example-proxy.com/proxy-login, and you were instructed to use port 3333, and your username is foo, and your password is bar, then you would put http://foo:bar@www.an-example-proxy.com:3333/proxy-login in the URL field on the Auto tab under Settings > WiFi > ESSID (Network Name) > HTTP Proxy (this doesn't sound too much like an automatically configured proxy to me, though, but this should get you logged on).


How can I gain access to the Windows 10 BitLocker encrypted drive on Mac OSX?

By default, we couldn't open, read and write a BitLocker drive on Mac. But take it easy, the BitLocker Genius tool is a really simple and user-friendly tool that can help you get access to the BitLocker drive without any data loss.

When you meet "The disk you inserted was not readable by this computer" error, you can click on Ignore button. I'm also a user that know little about computer. But I insert the drive to Mac and type my password then that drive is able to work normally.

Besides, you can unlock the BitLocker encrypted drive on Mac using a recovery key as well.

Photos App deleted all of my photos during a transfer to an external drive

As Tetsujin said, I agree that we cannot help much with the information provided.  But I'd be surprised if they were gone (reasoning at end).  However I will make an assumption that you have a photo library in /Users/username/Pictures/Photos in Library.photoslibrary

I would right click on the "Photos in Library.photoslibrary" file - select "show package contents."  Go the the folder "Masters" and see if you can find your pictures in there.  Do this for both where you copied the folder to and where you copied the folder from.

You can also search in here for something like *.JPG or *.JPEG or type JPG and select kind: JPEG Image.

Anyways, if the images are no longer stored in the package contents of either where you copied it from or where you are copying them to, unfortunately without significantly more advanced methods, they are most likely gone.  However most protocols do a write, verification, then delete, so I'd expect that the file is just not configured properly for Photos to read and your pictures are still there, just the Photos app isn't seeing them.  For example in terminal when you execute a "mv" command you are actually doing:

rm -f destination_path && \
cp -pRP source_file destination && \
rm -rf source_file

Notice the &&.  The destination file is deleted no matter what if it's already there (overwriting a file, so if the copy fails that file is still removed).  The copy, however, must be successful before the source file is deleted.  It doesn't follow symbolic links, but Photos used Hardlinks to migrate from iPhotos to Photos to save space.  So this is not an issue.


Fan Speed and Temperature on MBP Retina 13 2013

You should check the fans(s) in a MBP on a somewhat regular basis. There is a grid in the exit that channels the air coming out of the fan which tends to plug with lint. Remove the bottom cover of the machine and remove the fan(s). You will probably find a wad of lint obstructing the grid.


How to disable predictive text on Mac OS Catalina on iMessages

Resolved. While having iMessages, opened, go to Edit -> Spelling and Grammar -> uncheck all.


This should be sufficient. After changing the MAC address this way you could use e.g. Wireshark to capture the network traffic. The new MAC address should be shown there. At least this works on my macbook.


Problem: How to clear all remnants of random.py, random.pyc, and random.pyo that isn't part of Python's standard library?

use mdfind to locate all the files with that name (you might need to grep -w for the string or use mdfind with a "kMDItemFSName == whatever.py" clause)

Once you know where you've sprayed those files, you could either edit it into the question or decide to do a clean install / migrate user data or remove all the python and then patch that together from a clean install on an external drive.

It's had to know what specific things you've done, but hopefully a few of the tools can narrow you down to some options.

If I were on deadline and just needed to know what version of python was running - I'd brew install python after setting up https://brew.sh

You'd then have three installations, but the one that runs from the shell is controllable with $PATH and you can be sure it's up to date with homebrew.


macOS Sierra and (wired) keyboard broken

I resolved all the issues. On the previous version (OS X) I was using Karabiner. On macOS Sierra since it was not working I've installed Karabiner-Elements.

I've deleted all of these, make sure to delete all the file. Rebooted. And now all is working properly.


Apple Mail, producing multiple duplicate drafts on gmail

I've seen this behavior using Apple Mail since macOS Sierra. I haven't found a workaround d yet, but I know the email is sent because there is a copy in my Sent folder. Once a week or so, I go into the Google Inbox (should work for classic GMail too) Drafts folder and delete the email threads that are marked "Draft". This clears up the duplicates from Apple Mail on next sync.

My guess is Apple Mail, when saving drafts periodically to the server (Google) while one is drafting an email, is not using the right mechanism (API call) such that every draft version collapses into one on Google end. This incorrect mechanism results in each draft showing up as individual "drafts".


Install knoppix on usb with disk utility?

I have come across a similar issue merely trying to image dmg files to external disks with Disk Utility.app. Apparently, Disk Utility would prefer that before you begin your restore that you select the disk image in the left, and under the Image menu, select "Scan Image for Restore," and after that process completes, then try the imaging operation. If you have already errored, you need to quit Disk Utility and relaunch it, or you will continue to get the same error.


dd command finished very quickly but does not transfer data

Everything is OK except that you shouldn't use ~ in dd commands (it's not forbidden but error-prone) and of=~/dev/disk3s3 is a file in your /Users/yourusername/dev folder (which probably wasn't intended but explains the 326 MB/s) instead of the real destination /dev/disk3s3.

So better enter:

sudo dd if=~/Desktop/Windows.iso of=/dev/disk3s3 bs=1m

or much better

sudo dd if=/Users/yourusername/Desktop/Windows.iso of=/dev/disk3s3 bs=1m


How can I run an app, when using the full path?

Just at the dot at the beggining of the multilevel path : ./my/path/to/app/myapp Dot refers to the current dir. Or you can use absolute path from the root of your disk without the dot like /Users/Me/my/path/to/app/myapp Or if it is a jar file (you mentioned that it is Java app) you can start it as java -jar /my/path/to/app/myapp


No.  In short.

The longer answer:  All apps in iOS are sandboxed, meaning they effectively have no permission to do anything other than that which they were written for, other than through specific exceptions through API calls to other parts of the OS etc as allowed.  For example my Twitter app is allowed to access my contacts to use and set contact details as is deems fit.  Many apps (in my case Instagram,Tweetbot and Youtube) are allowed to send tweets through the Twitter App, but in all these cases (or any case where one app access some data or functionality provided by a second app) this is not a system wide availability.  Using said APIs an app can make portions of itself available to other apps, but unlike Quicksilver/Alfred/Launchbar on the Mac, this must explicitely be defined by the target app.  So taking for example the "Due" app for iOS which is a reminders app, it has an API that will allow other apps to create reminders in it, but that is all that other apps are allowed to do, and in order to do so they must be aware of the Due API.  As such the "Agenda" iOS calendar app has integrated the "Due" API, and is able to set a reminder in Due for an event created in Agenda.  But it cannot search for existing reminders in Due, or just start Due (or close it) etc.

So in order for an app like QS to exist on IOS, it would need to incorportate the API of every other app that it might want to connect to, and be limited by the fact that a) not every app (in fact I'd say very very few) actually has an API, and b) even where they do, they are often tied down to very specific functionality.

A bit rambly, but I hope this answers your question.

Just got an upvote on this, and re-read, and there is more the the answer than when I first made it.  There are a few apps these days that are trying to get closer to what the OP wanted, by effectively collecting and allowing the use of as many of these 3rd party APIs as possible in one place.  One such ass is Launch Center which collates APIs for nearly 50 apps, allowing you to do all sorts of actions from a single place - it's no quicksilver replacement, but it is an effective way to get at particular app functions directly rather than having to open the app and navigate to the function manually. - 1 example, is using clipboard contents for all sorts of things - tweet using clipboard contents, new task from clipboard contents etc etc.  Very useful.

Which SSDs are compatible with my old Macbook Pro?

Everymac.com is as close to a comprehensive source of system information as you'll find. In the case of your Mac, you can see it has a 1.5Gb/s SATA interface. So you won't be able to get the full potential sequential transfer speeds of a recent SSD, but keep in mind that the most noticeable benefit of an SSD comes from the random access speeds, which are less likely to be bottlenecked by the SATA interface.

It's also worth considering that SSD prices have come down a lot lately, so you're less likely to save much by getting an older model. I'd recommend looking at the Samsung 830 series or the Crucial m4. Both have excellent performance and good reliability.


How can I completely disable OS X Sierra "Storage Optimization?"

Optimized Storage isn't a single feature you can turn off in a single place; it's a bunch of similar features that you'll need to check and (if necessary) turn off individually. That Manage Storage window you got to from About This Mac is designed to let you turn on various Optimized Storage features, but not really useful to check their status or turn them off.

There's a good explanation by Adam Engst in two articles over at TidBITS: Explaining Sierra’s Optimized Storage and How to Turn Off Sierra’s Optimized Storage. I'll attempt to summarize.

Files: in System Preferences > iCloud pane > iCloud Drive Options button > deselect "Desktop & Documents Folders" (to prevent those folders from being stored in iCloud) and "Optimize Mac Storage" (to prevent deletion of local copies of the documents you do explicitly store in iCloud).

After closing that Options dialog, turn off any other kinds of that you don't want to have synced with to iCloud. Note, however, that for some of these data types, you can enable them here and then use the relevant app to choose which items get stored locally and which are synced.
Trash: In Finder, choose Finder menu > Preferences > Advanced tab > deselect "Remove items from the Trash after 30 days".
Photos: if you turned off iCloud's Photos feature in the iCloud preferences, you're done. If you want iCloud to store and share photos, but not delete local copies, you need to go into the Photos app, choose Photos menu > Preferences > iCloud tab > deselect "Optimize Mac Storage".

Note that Adam recommends that if you do use iCloud to share photos across your devices, you should have one Mac set to "Download Originals to this Mac" and not to "Optimize Mac Storage", and then make sure that Mac gets backed up. Seems like good advice to me.
Email attachments: in the Mail app, choose Mail > Preferences (not "Accounts"!) > Accounts tab, then for each account do Account Information tab > Download Attachments pop-up menu > choose "All".
Videos in iTunes: in the iTunes app, choose iTunes > Preferences > Advanced tab > deselect "Automatically delete watched movies and TV shows".


iPhone 5: Does the Wahoo Key work with the Classic-to-Lightning adapter?

Yes it does. According to Wahoo Support, one would be

  ... able to use the lightning adapter to continue using our Wahoo Key.
  This would add about an inch to the bottom of the iPhone.
