Why is Apple telling me to change my password after receiving a password reset email?

I'm not sure this question is actually on-topic here because you're effectively asking why Apple does something? That said, I offer this answer in the event it is kept open, and because I have worked in the IT Security field.

At the outset, I'm assuming that the email you received was a genuine email from Apple and not a phishing attempt.

The reality is that if someone other than you has requested a password reset, then you should assume they are up to no good. And, if that is the case, how many of your other online services are they also trying to access/reset?

Unfortunately, many online users use the same password for many accounts. And this vulnerability is the number one way that hackers (etc) breach accounts. For example, you would have heard of the iCloud leaks of celebrity photos (known as The Fappening) that occurred in August 2014. While at first it appeared that the fault was somehow related to Apple's iCloud services, after an investigation Apple stated:

  The leaked images were the result of compromised accounts, using "a very targeted attack on user names, passwords and security questions, a practice that has become all too common on the Internet". None of the cases we have investigated has resulted from any breach in any of Apple’s systems including iCloud® or Find my iPhone.

Source: Apple Media Advisory

This highlights why Apple would want you to change your password. Say you were being targeted by someone, by obtaining your password from one site they know there's a good chance you've used the same password on another. And if someone has deliberately tried to reset your Apple ID password, then from a risk management perspective you have to assume they've also tried accessing some of your other online services.

So, by Apple telling you reset your password on their service, they are trying to help you manage that risk.

Unfortunately, it's often not just the same password people use on their accounts, but the same security questions, the same recovery emails, etc. So, resetting your password is an excellent precautionary measure to take.

Finally, by Apple stating in their email to reset your password without delay, they are exercising their duty of care and this would be very important in the event of a breach and/or subsequent legal action.


Should I install the AX88179 USB Ethernet Driver - or any other external driver?

Should be safe, but make sure you have a backup to revert to - just in case.

Current drivers would appear to be v2.2, according to the Asix site

The folder Library/StartUpItems is empty

The file the preference pane loads the list of items from is:

~/Library/Preferences/com.apple.loginitems.plist

It is a binary file. You can use Xcode to open it.

For example, if you add iPhoto to your login items:

your com.apple.loginitems.plist will look similar to this:


I own a Shure headset with 3 connectors and it does not work on my MacBook Pro Retina 15''late 2013 nor does it with my iPhone 4S --- only the channel marked with 'left' works. And even the 4 connector versions are different among the various Notebook/Phone manufacturers compared to Apple. There are special Apple compatible versions advertised. Best, Peter


Running two separate instances of Safari in the same user session

You can also type in the Terminal.app

open -n -a Safari

This will open an new instance of Safari even if one is already running. Not every application supports this, like Finder or FireFox. Those applications prefers to have one instance running at a time.


Does an iPad consume more battery power when there are multiple applications open?

Under normal circumstances only one application is in the foreground and actually running. Of course what that app is doing can have a big effect on battery life.
Other applications may be multitasking, but only in very specific circumstances - it's rare. Most apps will actually be doing nothing, so the answer is  conditionally, "no".
When you tap the home button the foreground app receives a set of messages that allow it to prepare for and then enter a background mode. The app doesn't have to terminate completely but it is not running either. By default apps may not continue running in the background in iOS. They may request permission to run for up to ten minutes in the background (for example to complete a download) when they are notified that they are about to lose foreground status. Abusing this would be one way to get an app rejected by Apple.
Fraser Speirs recently wrote a very interesting blog post about this which was widely retweeted by developers, because it is right, and current for iOS 5.x.
Quoting from it:

There are exactly five kinds of apps allowed to run indefinitely in the Background state in iOS 5:

Apps that play audio while in the Background state. A good example is
Instacast while it's playing a podcast.
Apps that track your location in the Background. For example, you
still want voice prompts from your TomTom navigation app, even if
another app is Active.
Apps that listen for incoming VOIP calls. If you use Skype on iOS,
you can receive incoming Skype calls while the app is in the
Background.
Newsstand apps that are downloading new content.
Apps that receive continuous updates from an external accessory in
the Background.

Now if you are running an app that fits into one of the above categories it could be performing background processing. If it is a badly written app it could possibly be doing unnecessary processing. If at the same time you were running a foreground app that is demanding of processing resources then it's possible that killing the background app could make your foreground app go faster.
However! If you look at the categories you will see that these are all things that you would want to do if you were using those apps. You would not want to be able to receive a Skype call only when you brought Skype to the foreground. You would not want TomTom to stop giving you directions just because your passenger started to check email. So terminating apps is almost always a bad idea.
Now a word about the Recent Apps List that you bring up by double-clicking the home button. Notice the name is not "task list" or "multitasking list" or anything like that - it's just a list of recent apps. Some of them may be in the background, suspended and ready to run. Some may be terminated and not running at all - if tapped they would have to start running from scratch. An app from one of the listed categories may even be running in the background. But this list gives no indication of what is running right now. You can remove apps from the list but if the app wasn't running it can't be terminated. Proof: do a hard reset of your phone, letting it boot from the white apple screen. All the icons remain the same. Apps that may have been running are now not running but their icons remain.
Generally speaking there is no need to manually remove an application from the recent apps list.
If you really want to terminate an app that is currently in the foreground without switching to switch away from it before terminating it via the recent apps list, you can hold down the sleep/wake button (top of the device) until slide to power off appears. If you then hold down the home button until the device returns to the springboard, the app is terminated. (If you press Cancel and return to the app instead it is not terminated.) Proof: use an app with state - e.g. do a search in the iTunes Store app. Terminate it in this way, when you reopen the app your state is gone. If you don't terminate it your state remains.
Generally termination of the foreground app is never required - as you may have seen, an app that crashes is terminated by the phone automatically as soon as the watchdog process detects that the app is not responding to system events.
From the iPhone OS 4 press event in 2010:
    Q: How do you close applications when multitasking?
    A: (Scott Forstall) You don't have to. The user just uses things and doesn't ever
 have to worry about it.
    A: (Steve Jobs) It's like we said on the iPad, if you see a stylus, they blew it.
 In multitasking, if you see a task manager... they blew it. Users shouldn't ever have
 to think about it.


Move a hard drive from a mac book 2012 mid to a Mac Pro mid 2012

Sure you can - it will even boot from it if you ask it to by holding Opt at the chimes.

Your only issue may be to get it to physically fit the drive sled in the Pro. For that just get a physical adaptor so that the connectors line up properly.

OWC are well-known for their Mac-compatible products - selection of their drive adaptors. Make sure the one you get is for a 2012 Mac. I'm not certain if the adaptors need to be different [they probably don't, you just need a 2.5" to 3.5" adaptor, cheapest, first in the list] but I do know that the earlier Mac Pros had very very slightly different sled designs. Really hard to tell by eye, but they are not swappable.
I have two early Pros & two late Pros… & the number of times I've tried to use the wrong sled… D'oh!
I have one of their adaptors on a 3,1 but I've never actually tried it in a 5,1. It came with the machine so I never had to spec it myself.  My 5,1s I actually have SSDs mounted into the optical bay, which needs a slightly different adaptor type, 2.5 to 5.25, as opposed to 2.5 to 3.5.


How to transfer contacts from iPhone to PC?

You can use one of the free apps (e.g. My Contacts Backup) on the AppStore to export all of your contacts and Mail it to your e-Mail account or save it to Dropbox etc.

Another way is, if you have your Contacts on iCloud. SignIn on icloud.com navigate to Contacts - Press cmd+A or ctrl+A on Windows. The in the corner left ist a Gear Symbol - and select Export vCard


A quick Google search led me to this : https://discussions.apple.com/thread/7939592

  The suggestion on the page is to try Internet Recovery mode, and that from there to check the hard disk. There is a comment further down where the user says they were finally able to connect to Internet Recovery

However, it does sound quite possible that you have a bad drive (SSD or hard disk). Contact Apple to see what your options are regarding a replacement/repair.


Running defaults command as root vs regular user

Yes , it's different if you run as root or regular user. In the first case you have all permissions, the second you have the permission of the domain of the application. Not every time the permissions are the same.


OSX AppStore Avoid updating certain apps

If you click the More button at the bottom of the listed item, then right click after it has expanded, you should get a 'Hide Update' button - but it doesn't work for all apps.

Tested today with

Camera Raw 5.0.7 - Hide Update button
OS X Update 10.9.5 - Hide Update button
Xcode 6.0.1 - no Hide Update button


Random shutdowns that look like kernel panic

Go into recovery mode and reinstall MacOS. That sounds like a software issue. Give that a try, if the results are still the same, then you may have a bad drive.


This depends on the type of WIFI network that is being produced by your WIFI router, as to whether the TC can extend it or not.  Basically, the best way to find out is to experiment on your TC - fire up your Airport Utility, and in the Wireless configuration option, look to see if it will let you extend rather than create a wireless network, and then see if will find your existing network.

EDIT: I should add that the brand of wireless router is a primary consideration as well. Many brands don't play well with TC, AE, or any other Apple networking gear.


How to access iMessage library using Sequel Pro on macOS

Messages uses an SQLite database structure, so you can't open this with Sequel Pro. You can open the Messages database at ~/Library/Messages/chat.db using DB Browser for SQLite.


Have you tried running the mouse over to the left/right corners of your MBA screen? It should jump onto the projector screen - I think Lion is default for ext. screen to be on the left.

You should be able to drag any app then over to the screen in the same way the mouse passed across.

Where the big screen is compared to the little screen can be configured in System Preferences > Display > Alignment.


iPhone 3GS (jailbreak) not recognized in iTunes

The latest iTunes does not support as much older versions of iOS as iOS4 is.

I recommend you to uninstall your current iTunes, clear cache ... etc., reboot your computer and then download and install an older version of iTunes.

Once you are done with the above steps, I can recommend you to make sure that the USB port on your computer works well and to check the USB cable of the phone as well. Last thing that I can suggest is to have your iPhone unlocked and follow up if anything occurs on it's display.

Let us know if any additional information is needed.


Solving in somewhat unusual way:

a) You claim "However linking succeeded.", so in project properties pane, go to Products folder, then click on product name. On the right-side pane, under Identity and Type, you will find out the name of the product and the full path location. For one of my projects now i can find out:

  ~/Library/Developer/Xcode/DerivedData/prodname fnihcmsxnrxlstcumyviklyuofum/Build/Products/Debug/prodname

and a location attribute: Relative to Build Products - build folder was create by Xcode, you can find out "Build" also in Project Properties -> Build Settings -> Build Locations. (you can modify also according to your needs...)

b) Now for your missing library: also in Build Settings -> Linking you have the possibility to add your library at Prelink libraries, just click at the left of this item, two lines open below, Debug/Release, click on one line and a small + appears and add your library there.

EDIT: adding some pictures, as requested:

Selecting the Product:

Click on product name (rectangle on the picture) and the full path is to be found  on the right pane as in this picture:

Now, in the first picture: click on application name icon, will open building info. Building path(s) are to be found as shown here:

And scrolling down further, the linking options as revealed here:


Downgrading to ios 4.1 from ios 5 without shsh?

No. Without SHSH blobs it is not possible. And devices running the A5 (iPad 2 and iPhone 4S) it is not possible even with the blobs.


Will my 14.5V USB-C charger destroy my 9.7 inch iPad Pro?

This should be absolutely fine. I haven't tried it myself (yet) but Apple themselves state that you can use the 29W adaptor with the 12.9" iPad Pro, and other people have verified that it works (and doesn't cause damage).

This all came out before the 9.7" iPad Pro was released, and it doesn't look like Apple have updated the product page for their USB-C to Lightning cable, but I'm certain it will be fine. I've charged many an iPhone with an iPad charger without cause for complaint.

The device should only draw as much power as it needs/is safe.

In my case, I discovered that Dataless Snapshots might appear when TimeMachine is set off/on (automatic unticked/ticked), as it appears that after a few “new” Snapshots are taken, the oldest Snapshots prior to turning off/on TM become dataless.


Why does the website I'm putting into the reading list in Safari disappear shortly after?

Regarding the solution, that problem seems quite trivial.

The site that you want to save into your reading list doesn't disappear shortly after but is put on the bottom of that list.


Any downside to using multiple mail and calendar apps on iOS?

Yes, you definitely will double the data sent, if one uses two apps for the same account.

However, using different programs may be useful.  For example, if you want to separate your professional Exchange E-mail from your personal accounts.  This way, there is a logical separation, and you run less risk of accidentally sending out a personal mail on a business acount, and vice versa.  Some mail apps even have password or PIN protection (for example, Divide), which will keep your E-mail accounts safe, even if someone swipes your phone when you are using it.


how to check if it is safe to delete iNode file (or how to inspect its contents)?

If you're comfortable using the terminal, you might be able to figure out what the file is. If you're not comfortable using terminal, I wouldn't worry about doing this. I was doing this mainly for my own interest rather than any real need.

Open terminal and enter the following commands (enter the text following the $):

$ cd /lost+found
$ ls -l
total 10087432
-rw-r--r--  1 root  wheel  5164763151 25 Oct  2014 iNode10324487

$ file iNode10324487
iNode10324487: xar archive - version 1

This tells me the iNode10324487 file is meant to be of type xar, which is an archive file. A quick search for "binary file xar" finds the man page for the xar utility on OS X. This tells me that I can view the list of files contained within the xar file with the following command:

$ xar -t -f iNode10324487
Distribution
InstallMacOSX.pkg
InstallMacOSX.pkg/Bom
InstallMacOSX.pkg/Payload
InstallMacOSX.pkg/Scripts
InstallMacOSX.pkg/PackageInfo
InstallMacOSX.pkg/InstallESD.dmg
Resources
Resources/ar.lproj
...

So the orphaned file that I've got taking up 5.16GB on my disk looks like an OS X installer package. I'm pretty confident that I don't need that, so I can delete it.

Unicode escape is ctrl+[ , why does this work in terminal or vim, but not safari or other parts of OS?

For example if search a page in safari you can't escape out of the search with ctrl+[

It's because Safari is not operating in an ASCII/ANSI Terminal environment.

The Escape character is

octal: \033
hexadecimal: \x1B or ^[
decimal: 27

It's just a series of characters the terminal looks for that interprets it as actions or special characters.

As for working in vim (or vi), you aren't limited to sending ^[ (^ Control[), you can simply press the Escape key.  It will do the same thing.


There are apps which aren't content blockers, but which rather install a VPN on your device and route your traffic through this to block ads. This is still supported on devices which don't support content blockers.

 AdBlock
 AdGuard

For other devices which do support content blockers on iOS 9, there are many options available.

 Crystal
 AdBlock Plus
 Aqua
 AdBlock for Mobile

To add a content blocker, install it from the App Store, then choose Settings → Safari → Content Blockers and enable the content blocker. For apps which do not use content blockers, see the app itself for installation instructions.


With EAP-TLS, manipulating certificates, identity preferences and a single password entry all in keychain access can be done from the command line.

security set-identity-preference -c ${CN} -Z ${FINGERPRINT} -s com.apple.network.eap.user.identity.wlan.ssid.${SSID}

security add-generic-password -a ${USER} -D "802.1X Password" -l Default -s com.apple.network.eap.user.item.default -T /System/Library/SystemConfiguration/EAPOLController.bundle/Contents/Resources/eapolclient

security add-generic-password -a ${USER} -D "802.1X Password" -l ${SSID} -s com.apple.network.eap.user.item.wlan.ssid.${SSID} -T /System/Library/SystemConfiguration/EAPOLController.bundle/Contents/Resources/eapolclient

com.apple.network.eap.user.item.default and com.apple.network.eap.user.identity.default are for wired 802.1X.

com.apple.network.eap.user.item.wlan.ssid.${SSID} and com.apple.network.eap.user.identity.wlan.ssid.${SSID} are for 802.1X on wireless SSID ${SSID}.


Are former employees able to remotely wipe my Macbooks after they left the company?

If you want to completely "unlink" your MacBook from iCloud/Apple ID, change the Airport Card (WiFi adapter).

Apple uses hardware identifiers, including the embedded MAC (Media Access Control, not "Macintosh") address to uniquely identify it.

Change out that card, and your Mac will no longer be linked to the iCloud account.  They are relatively inexpensive and very easy to change - just remove the back cover and the single retaining screw holding it.

Finally, this should be a good example of why you don't allow employees to register company owned hardware as their personal devices.


MacBook Pro asks to reset password, but neither keyboard nor mousepad are working

I've solved the problem this way.

Turned off the computer manually by holding down the power button.
Attached an external mousetrack (Apple Magic Mouse 2) by USB.
Turned on the computer in recovery mode, by holding down the Command + R keys simultaneously while starting the computer, and releasing only when the Apple logo appeared.
When the recovery screen appeared, I used the Apple menu on the top left corner to restart the computer. It wasn't enough to tap the mousetrack in order to select the desired menu item, I had to forcefully press down on its surface.
The restart proceeded normally. Hurrah!


I'm not sure if macOS supports video over AVB, I've only seen AVB audio products in use w/ macOS so far.

Safari no longer defaults to typing in address bar. Why?

Your system could have been infected with adware and/or malware. See this Apple Support page on how to remove adware.

Time Machine backups (2 backups at same time)

By default, time machine excludes external drives that are mounted, but you can add them back into your backup in Time Machine "options" (found on the Time Machine Prefrence Pane). See here for more info: https://www.macworld.com/article/3153995/how-to-make-sure-time-machine-backs-up-external-drives.html

To add an external drive into the list of Time Machine Backup Drives, just use the "Add Time Machine Backup Disk" in the Time Machine preference pane.

Regarding your Question (2), You can not direct a some of your backup to one time machine, and the rest to another, thought that would be a nice feature. I personally use an rsync script that runs nightly to solve a similar problem, though that's nowhere near as convenient (or user-friendly) as Time Machine.


Can I use Time Machine to back up data to a Windows shared drive?

In order to create a Time Machine backup to an unsupported drive (pretty much anything that's not formatted HFS+) you need to run the following Terminal command:

defaults write com.apple.systempreferences TMShowUnsupportedNetworkVolumes 1

Your share will now show up as a valid Time Machine destination in the Time Machine Preference Pane.

Time Machine will then create a disk image on that drive that will act just like a HFS+ drive for Time Machines purposes (hard linking, etc.). One advantage of using a disk image over using the entire drive is that you can limit the size it will grow to of the disk image using Disk Utility.

Be sure to check Louis Gerbarg's answer as well for why it's unsupported and you have to jump through a hoop to enable it.


Terminal, Opening Applications Directory

New shells start in your home directory by default, i.e. /Users/username (~). You then specified a relative path to change directory, Applications, which changed directory to /Users/username/Applications.
This is a different folder to the system-wide applications folder at /Applications. When you cd /Applications, the leading slash provides an absolute path rather than relative path, starting at the top of the volume rather than the current working directory (which is your home folder for new shells).


Adjust horizontal scrolling speed on a mouse or trackpad independent of the vertical speed

You can make the horizontal scroll speed faster and independent by overriding the native ⇧+scroll function with SteerMouse's feature to define a custom relationship between inputs, scroll speed, and direction. You can even assign a scroll speed acceleration value if you want to combine slower and faster scroll speeds for enhanced precision.

Here's how to set it up:

In the SteerMouse preference pane, select the "Mouse" tab.
Switch the "Horizontal scrolling" option from "Tilt" to "Roll" (Fig. 1). This should be enough to let SteerMouse take over the handling of horizontal scrolling, which is what is invoked when you use the native ⇧+scroll function, so if you don't wish to make further scroll speed adjustment, you can stop here.
Select the "Scroll" tab (Fig. 2).
Click the "Roll Horizontally" button.
Make any further acceleration and sensitivity adjustments. You can also invert the horizontal scroll direction (Fig. 3).


I had this issue come up recently when traveling out of town, and having issues connecting to hotel WiFi, and in doing so did some IP sniffing, and trying to get onto a site via IP, which had a certificate mismatch, which I first added an exception to.

To get to the bottom of it, I first got info from the certificate in the browser, but nothing turned up in Keychain access looking for that. What I did to fix this was click on the lock icon in the URL bar, then clicked on Show Certificate. In that window, go to Trust > When using this certificate, and click on the ? icon to the right of the settings, which brings up a Mac Help window, which if you click on the link Open Keychain Access for me, where you can see the certificate highlighted in the Keychain Access listing. Tap the info button on the bottom of the screen, and from that window click to expand Trust, then change When using this certificate to Use System Defaults. Once this is done, flush your caches, close and restart the browser, and test to confirm.

Here's a screen capture with that first info button highlighted:

How preserve JPEG date stamps during Automator scaling?

Here is one way of achieving the stated goal with an Automator Service. Instead of using Scale Images use Run Shell Script with settings, Shell: /bin/bash and Pass input: As arguments and add the following code to it:

for f in "$@"; do

        # Get the creation date time stamp of the target file, saved as 't'.

    t="$(/usr/bin/GetFileInfo -d "$f")"

        # Get the pixel width of the target file and divide it by 2 for a 50% scaling, saved as 'w'.

    w="$(/usr/bin/sips -g pixelWidth "$f" | /usr/bin/grep pixelWidth | /usr/bin/awk '{print $2/2}')"

        # Scale the target file.

    /usr/bin/sips --resampleWidth $w "$f"

        # Set the modified and creation date time stamps of the target file to the saved value held in 't'.

    /usr/bin/SetFile -m "$t" -d "$t" "$f"

done
        # Notify User operation is finished.
/usr/bin/afplay "/System/Library/Sounds/Purr.aiff"

Note that the last line in the code above can be omitted if you are going to use Show Growl Notification, which I don't have and why I used a system sound.  This was done under OS X 10.8.5 and you'll need to verify the path to the executables are the same on your system, although they should be the same.  The reason I'm using the fully qualified pathname of each executable is because Automator errors out if I don't.  You can get the FQP in a Terminal using which, e.g., which sips returns /usr/bin/sips.

Note that GetFileInfo and SetFile are a part of Xcode Tools and if not already installed you'll need to install, which can be triggered by typing GetFileInfo in a Terminal and following through with the prompts.

You can read the manual pages for each of the commands used to garner a more through understanding of what's happening.

Manual Pages for: GetFileInfo, sips and SetFile


Is there a common reason for a Macbook battery to disconnect from the logic board?

It's option 3 - "Other."  There are two possibilities for your battery becoming disconnected with your logic board and both have to do with the molex connector:

The connector on your battery is broken/defective.  If this is the case, the warranty on the battery (provided you are still within the warranty) should get you a replacement and have this fixed.
The connector on your logic board is broken/defective.  If this is the case, the only surefire way to fix it is to have the connector replaced.  This will involve soldering of the logic board.

If repairing/replacing the logic board is out of the question and the everything works fine with the exception that the connector won't stay connected, you can secure it in place with some Kapton tape.  It won't be the most elegant solution, but for under $20 for the roll of tape, it's a much more cost effective solution.

As for your first two speculations...

Shocks. The amount of destructive force your Macbook would have to go through to "shock" the connector out would destroy your Macbook completely.
Ejection system.  You would see some sort of mechanism to do this.  If your MBA senses things are getting too hot, it shuts the computer down.  There's nothing in any computer that "ejects" connectors.

Is Apple's multi monitor still not working on Mavericks or do I misunderstand it?

When you say "full screen", I'm assuming you're referring to the full screen button on the top right of a window, as opposed to the "expand" green button on the top left of a window.

Mavericks has "solved" the multi-monitor issue by allowing multiple and independent spaces on each monitor. In pre-Mavericks, when you move to a different space on one monitor, all other monitors follow. In Mavericks, they are independent, meaning you can move each monitor to different spaces without affecting the others.

In relation to full screen apps:

Pre-Mavericks, going full screen would move one monitor to full screen and all other displays to a black/empty/useless space.
In Mavericks, all other monitors remain independent and free to access any of their spaces (allowing those monitors to remain useful).

So in response to your question

Full screening an application on one monitor has no affect on the others, and full screening it on your mac mini screen, should not make the app go full screen on your 27'' screen.
When you maximize a window on one screen, and then drag it to another monitor, TextEdit does not resize itself to fill the screen (whether it be to shrink when going from your 27" to your 13", or grow, going to your 13" to 27")
Overall I'm a little confused about your frustrations, but you cannot make it so a window grows proportionally based on the monitor. What I mean by this is that you cannot make it so if you have TextEdit open on your 13", and it covers 60% of that monitor, when you drag it over to the 27", TextEdit won't automatically appear as taking 60% of the 27" monitor. It will appear as the same size it was on the monitor you're dragging it from.

There are multiple 3rd party apps that help you manage and arrange your windows in Mac OS X that may help you. But as far as I am understanding, none that will help your issue, if you're referring to the top right full screen button.

You can use apps to help magazine your windows:

Divy:   http://mizage.com/divvy/
SizeUp: http://www.irradiatedsoftware.com/sizeup/
Moom:   http://manytricks.com/moom/

You may like Moom the best, and it is described: Do you spend a lot of time moving and zooming windows, so you can better see and work with all the content on your Mac? Instead of doing that work yourself, let Moom handle the task for you.


Can I use 16GB DDR3-1600MHz RAM in an early Macbook Pro 8.2?

It's not possible to use RAM running at 1600MHz in your Macbook Pro 8.2, because it's not supported by the processor.

Your Macbook Pro has the Intel® Core™ i7-2635QM Processor which only allows DDR3-RAM running at 1066/1333MHz according to Intel. (see link for official specs)

While the 2635QM processor does not support 1600MHz memory, it does support 16GB RAM:


Force all applications to use system proxy in macOS Sierra

By default, applications that don't have a build-in option to configure proxy settings will automatically use the system proxy. However, for certain applications (like Terminal), no proxy will be used. If you want to have a system-wide proxy that can't be circumnavigate, take a look at "VPN Plus". Basically it creates a "network tunnel" in the system preference, acting as a network device, and all traffic routes through it. I haven't done any research on that so I can't provide a lot a details about that, but that is a possible solution.

I can't find any reason to why would you want to use a proxy for Adobe or a VPN client. Adobe softwares generally don't require the internet to work, while VPN client connects you to a proxy.

One more thing - our school's IT manager sets up a school-wide proxy that allows us to access Google and Wikipedia (I'm in China). This is a far more efficient way than setting up on one's laptop.

What are the current restrictions on iOS emoji usage?

Whenever in such doubt when publishing an iOS app, your first step should be to thoroughly go through the App Store Review Guidelines.

Searching for emoji, these are the relevant matches in the document:

  4.5.6 Apps may use Unicode characters that render as Apple emojis in their app and app metadata. Apple emojis may not be used on other platforms or embedded directly in your app binary.

  5.2.5 Apple Products: ... Apps and extensions, including third party keyboards and Sticker packs, may not include Apple emoji. ...

It is clear that using unicode characters which render as Apple Emojis is permitted, but using Apple Emojis is not allowed.


Host same application with different design

Only if there are already tons of apps that will let you navigate, say, The Smithsonian Museum of Natural History."  Then that one app for the smithsonian MAY be rejected.

But, I suspect there are not, so you should be fine.

Similarly, since you'll presumably be adding additional apps with different functionality, say the next one is for the Guggenheim, you should be fine.  The 2 apps couldn't possibly be used as a replacement for each other.

Apple's concern here is keeping out over-served functionality.  There are so many "fart" apps that yet-another-one can't possibly help any user anywhere beyond what's already available.  Museum apps are well outside of that scope, assuming you create a quality app with a great UI for museums that don't already have several hundred apps.


macOS Yosemite->High Sierra update not sticking

"What's going on here?," Indeed.

I can't guess, it could be a damaged disk or disk structure, permissions issue, yadda yadda yadda...

But there are a few things you can try. Note these suggestions are going to be kind of generic due to the nature of the problem and because you didn't include your Mac model in the question. It would be best if you added that to your original question.

Boot into Recovery Mode ⌘ CommandR when restarting your Mac. When you have a menu bar available start disk utility, select your drive and click on First Aid. If the drive shows clean when First Aid has completed you can quit and reboot normally. If it shows problems (fixed) then re-run First Aid until you get no errors. If it is unable to fix, add the error messages to your original question.

Now, look in your Applications folder for an app called "Install Mac OS High Sierra" or something like that. Once you have verified you have the app I would use the freeware installer creator DiskMaker X a blank 8GB USB key and make a bootable High Sierra install key.

Once you have that, insert it in any USB port and reboot your Mac holding the ⌥ Option key. Select the installer USB key when the boot disk selector appears and let the Mac boot from that. It will take a little longer than usual.

Follow the prompts to install High Sierra. Important to note you should NOT use Disk Utility to reformat/repartition your drive, just install right over top of what is already there. An upgrade install.

Report back on those results.

Note if that fails you may need to back up your Mac and use the installer to reformat the boot drive and then install High Sierra and restore from your backup.


How to get to know which app causes the "would you like to install java?" dialog in Mavericks to appear?

Since your screenshot references java where the app name usually is written, it suggests that it's the command-line version of Java that a given app is trying to run.

If it appears at specific intervals, it either an app that you have open or a periodical job running automatically in the background (Which, ironically, could be the Java Updater itself).

A quick way to check out which of your installed applications use Java is to run this command in Terminal (/Applications/Utilities/Terminal.app):

find /Applications -type f -name *.jar

This isn't 100 % accurate but it can give you a rough idea. Dreamweaver and Flash from Adobe, for instance, uses Java.

To get a list of currently running automated background scripts use this command in Terminal — You should run in as close as possible to the moment when the Java popup appears:

launchctl list

(Credit to this thread on Apple Support, it's also useful in understanding launchd)

This will, sadly, only give you a list of processes running and not why or what they're running.

Finally, you might want to take a look at the files in ~/Library/LaunchAgents (In Finder use Cmd+Shift+G and paste in the path. This directory shows the periodical jobs that you've setup as a user (sometimes indirectly through an install). Maybe one of these use Java.


Will enabling FileVault convert my HFS+ disk to APFS?

FileVault and APFS are two very different things; enabling one doesn’t enable (or necessitate) enabling the other.
FileVault is encryption - it scrambles, to put it simply - the contents of your drive with a known key.  Specifically, it uses a 128bit AES encryption with a 256bit key.  See Use FileVault to encrypt the startup Disk for additional details.  You can encrypt JHFS+ formatted volumes as well as APFS volumes.
APFS (Apple File System) is simply Apple’s next generation file system.  As far as encryption goes, it supports it natively unlike JHFS+.


MacBook Pro 13” mid-2012 iSight cable port broken

I know of no Mac that has a temperature sensor as part of the cable assembly nor a temperature sensor as part of the FaceTime camera.
However, I can tell you from direct first hand experience, there won’t t be any temperature related issues from a damaged FaceTime cable or camera.  If had the ripped off in the same manner to yours, cut and even purposely removed.  None caused any issues.


How do I use a U2F token when adding a Google account to my Macbook Pro

There isn't a way to use your U2F token in this scenario.  U2F depends on browser support, and as of August 2018, only Chrome, Firefox and Opera support it.

As a workaround, you could set up Google Authenticator and use that to log in.


delete ibooks and podcast app from ipad air2

No, the stock/standard Apple apps can't be deleted.  You can delete individual podcasts or iBooks, but not the apps themselves.  Hopefully, Apple will allow this in a future iOS release.

iPhone Today View for Apple calendar Whats Up Next showing wrong time

I suspect there's a time zone issue if you're travelling a lot between time zones.

Does it help to go into the Calendar settings in iOS and set Time Zone Override? I'm not sure how it works, but worth having a look at it. Additionally, you can also set the time zone for individual events for particular time zones.

I've attached a screenshot of the Time Zone Override screen in the Calendar settings on iOS.


FaceTime launches on my Macbook when I have incoming phone calls, even though I'm not logged into iCloud

Disable Calls on nearby devices on iPhone too. Settings > phone > Calls on nearby devices.


When you're on the Google Images page scroll all the way to the bottom. There is a choice there to use either Google Tablet or Classic (defaults to tablet on the iPad). Click on classic and you should get the same options as on your mac/pc.


How to open a port in macOS Sierra 10.12.4

The linked How-to is wrong!

You simply can't open a port in a firewall. You can block a port or not. By default pf is disabled and doesn't block anything. If you enable stealth mode in the Application Firewall, pf will be enabled via the com.apple/250.ApplicationFirewall anchor with a very limited set of rules:

scrub in all fragment reassemble
block drop in inet proto icmp all icmp-type echoreq
block drop in inet proto icmp all icmp-type echoreq
block drop in inet6 proto ipv6-icmp all icmp6-type echoreq

Except incoming IPv4/6 ICMP echo request, pf won't block anything. The default pf.conf doesn't contain any block all ... or allow all ... rules.

To open a port on your host, you have to launch an app which opens a listening port. Example nc:

nc -l 12345

After entering the command you will be asked to accept incoming network connections for nc by the Application Firewall.

To connect to nc listening at port 12345 from remote simply enter nc hostname 12345 on a second host (replace hostname with the host name of the Mac running nc).

You can check open ports from remote by entering nmap hostname -Pn (if stealth mode is enabled).


If you view by Songs rather than Albums, you'll see they are unchecked.

iTunes will always skip unchecked songs, by default.


How to show progressbar in App store during installation?

There should be a progress bar underneath the Launchpad dock icon.

If you removed Launchpad from your dock, open it through Spotlight, then search for the icon of the app you are installing (which in your case would be Xcode). There should be a progress bar and further status information on it.


Is there a way to test my iPhone for any potential rogue apps

Apple is generally pretty decent with reviewing applications - HOWEVER - if you need to an application such as  http://www.digidna.net/products/diskaid   may help a great deal.

Truth to be told - the iphone is not secure period.   Just attend one blackhat event and keep your iphone bluetooth and/or wifi enabled and voila - folks can show you why

Nicolas Seriot, from the Swiss University of Applied Sciences, has found some alarming design flaws in the iPhone operating system that allow rogue apps to access sensitive information on your phone.   (click on that last sentence for the link.


Changing yahoo messanger's status using mac terminal

How do I search all hidden files that are in hidden folders using Terminal?

mdfind seems to ignore a lot of hidden files. mdfind 'kMDItemFSInvisible==1&&kMDItemFSName==filename' does list .DS_Store files, but not for example .bash_history. I haven't found any way to search for files in some hidden directories like /private/etc/.
Anyway, Find Any File is a lot faster than find.

Find Any File is a program for Mac OS X that lets you search for files on your disks.

Contrary to Spotlight, it does not use a database but instead uses the file system driver's fast search operations, where available. This lets you search for file properties such as name, dates, size, etc., but not for file content (use Spotlight or EasyFind for that).
Find Any File can find files that Spotlight doesn't, e.g. those inside bundles and packages and in inside folders that are usually excluded from Spotlight search.
Finally, it is quite fast. A search only takes a few seconds on an internal hard disk or SSD. Try for yourself!


I'm looking for a good, lightweight email client

Popular email clients for the Mac include:

Apple Mail - my current favourite, especially in Lion.
Postbox - Paid for, but feature-rich and quite polished AFAICT
Thunderbird Free and open-source. Extremely configurable with a similar extension ecosystem as Firefox.
Microsoft Outlook - A very fully featured email and calendar package. It replaces Microsoft's previous Mac email client, Entourage.
Sparrow - A unique email application. The layout encourages casual, Twitter-like conversation by evoking the timeline view of popular Twitter apps. It's pretty trendy at time of writing.
Mailplane - Basically an optimised, dedicated Gmail browser window. Worth looking into if you're a heavy Gmail webmail user.
MailMate - I hadn't heard of this one before, but it has a good review at Lifehacker.


Wifi still going dead on upgrade from iOS 6?

No-one here can give you a 100% definitive answer to a question starting with Could... (if you get what I mean).

However, what I can tell you is that in most cases where an iPhone's Wi-Fi has seemingly stopped working after an iOS update/upgrade, they can be readily resolved by the user. In those rare cases where the issue has been hardware related, the iOS update/upgrade has only acted to aggravate a pre-existing problem.

If you have a compelling reason to upgrade your iPhone 4 to iOS 7, then do it. However, as always, be sure you do a full backup first. Also, in case you aren't already aware, the latest version of iOS officially supported on the iPhone 4 is iOS 7.1.2.

Finally, if you do decide to upgrade and find you do have issues with your Wi-Fi, then feel free to post another question here for help.


How to use the balance on your apple account in app store?

Just buy the app or the song or whatever and it will take from your balance first. I would check your settings to verify this, however.


Disk Utility works forever at trying to repair partitions

Disk Utility repair functions are (from what I have heard) just a front end to FSCK, so that will likely give you the same results. You could try another disk repair utility (diskWarrior, techtool, etc...), or if you have a recent backup I would be tempted to wipe the drive and start over.

If you have another Mac you could put that Mac into target disk mode, connect the two via Firewire or Thunderbolt and try the repair that way.

It is possible that the drive itself is damaged and beyond repair. The problem here is that disk utility is usually not smart enough to know when to give up. And repairs can take a long time (overnight is not unheard of) so unrecoverably damaged disks often initially diagnose similar to what you are seeing.

Failing other disk utilities or other Macs your best bet might be a visit to an Apple Genius. they will diagnose you for free, repairs may cost you if you are out of warranty.

Screen Time blocks Google websites because YouTube is restricted

Your problem is that Google, as part of its single sign-on (SSO) process, also logs you into YouTube. For most of the Google applications, it can set cookies that are valid on *.google.com, but for YouTube, it redirects you to https://accounts.youtube.com/accounts/SetSID with a sign-on token; you can see this URL briefly flash up when you log in.
It's this redirect that's tripping up your filter. As described in other answers, you can restrict your filter to www.youtube.com, or you might be able to explicitly whitelist accounts.youtube.com.


How can I create a bootable USB stick with Linux and FAT32 from macOS

You need to use diskutil through Terminal to accomplish this.

The command you would use is

diskutil partitionDisk diskX 2 MBR fat32 "LINUX" 80% fat32 "RESCUE" 20%

A few notes:

diskX is the identifier of your USB stick (use diskutil list to get that info)
For this example, I am using a 1GB flash and dedicating 80% of it to the Linux partition and 20% to the Rescue.  You can use actual size values like 800MB and 200MB rather than percentages.
You will need a boot loader (like GRUB2) installed.  If your rescue CD already has one, just dd the image to the "Rescue" partition.
"Linux" and "Rescue" are the names of the partitions
The partitions will be created in the order listed.

Per the man page:

partitionDisk device [numberOfPartitions] [APM[Format] | MBR[Format] | GPT[Format]] [part1Format
                part1Name part1Size part2Format part2Name part2Size part3Format part3Name part3Size ...]


Include additional data into iPhone backup files

You can using various third party backup and restore software. I like iMazing and know there are a few others out there.


I've experienced this issue and after a complete re-install and every troubleshooting regarding software tried out, I handed it in at an AASP. They determined the issue to be hardware, and exchanged the top case (which also means no more sticky keys).

So my best advise is, take a backup and go visit your local AASP.


Photos disappeared from messages (iPhone 4s)

Possible fixes…

settings > messages > turn iMessage off - wait - turn back on.
settings > general > reset > reset network settings.
[More thorough]
If you are using any other device with iMessages, disable them all (sign out).
Then on your iPhone, go to Settings > Messages.
Turn Message “off”.
Wait 5 seconds, turn back “on” and below under Send & Receive, remove any other emails or numbers for Messaging other than your primary number.
So you just have one under that section.
Now you should be able to get pictures.
If so, now you can re-enable Messages on all your other devices.

Note: The above methods have shown varying degrees of success, works for some to regain their history, others merely get the functionality back for new photos, but don't get their old photos back.

Searching Google would indicate this is a known bug, with no real fix as yet. If you have an iCloud backup, the data should be in there - extracting it would need something like iPhone Backup Extractor but it would appear that the only way to get them back into the messages, if nothing worked so far, is wipe the phone & set up as new, then recover from the last backup.


Purchases as default never disappear. If you can't open via App Store I suggest opening safari and search for "Angry Birds iTunes" or any other relevant app. When you open the page from safari, the iTunes App will open by default and you will be able to download the app.


Why are my command line utilities running so slowly on my Mac?

I actually figured out the issue today. It was caused by a piece of anti-malware software called Sourcefire AMP (Advanced Malware Protection). All of my issues went away after I disabled/uninstalled it.

I'm guessing that it was doing something like putting a delay on things in /bin, /usr/bin, etc. for "security reasons"... I'm guessing the GNU tools were not delayed because they weren't in the "blacklisted" directories.


The emergency call function only allows dialing emergency numbers valid for whatever area you're currently in, i.e. 911 in the US, 112 in the EU, 999 in the UK...

See the iPhone User Guide for more details.


Keyboard predictions when typing in Safari address bar (iPhone)

The QuickType predictions don’t show when the text field has autocomplete disabled.
This is most often seen in inputs where completions appear as part of the text entry in the app. For example, regular QuickType predictions don’t appear in the Safari address bar because Safari shows autocomplete suggestions from your selected search engine. This is the same for App Store search, Spotlight, and others.


Playing background sounds while talking in Skype

The easiest way to do this is to have your background sounds on your Skype audio is do do this via hardware; have the audio on a different set of speakers the microphone (or input device) can pickup.

It can be Bluetooth or USB (easier).  You can't use the headphone port because when you plug in the headphones, by design, the internal speakers of your Mac will disconnect.  For example, I use the Behringer UCA202 USB Audio Interface to connect my Mac to my audio system.  All music and audio from videos etc. are piped to this device.  System sounds are relegated to my internal speakers.

Skype audio (mic and headphone) are through the internal devices.  Additionally, I can mute my calls/music/whatever from this device without muting my system sounds; just by hitting mute on my audio device's remote.

However, when I play music or videos, I pipe the audio through the USB

So, if you need your Mac's background noises to be heard, you can pipe your System Sounds through the USB audio leaving Skype with the internal audio devices; or vice versa.  They will hear it.


iPod touch syncs to my new computer correctly - apart from my Apps. How to fix?

Try going to the App store on the iPod and purchasing a free app.  It will ask you for your App Store account credentials.  Once this works, try syncing again.   It should then move across all the apps.  Make sure that Syncing apps is ticked in iTunes too (by default it is but check anyway).

Hope that helps.


From the looks of the details on EveryMac.com your Mac will take up to macOS 10.13.x (High Sierra).

Apple's current macOS version is 10.14.x so you are actually in pretty good shape as far as that goes. High Sierra is still getting security updates and most released software will work on the last 2 to 3 macOS versions. Many will work on versions earlier than that.

You should be able to sign into the App Store and download macOS High Sierra. here is a link that will open that up in iTunes, https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?mt=12

Once you have upgraded to High Sierra that will be the last major revision of macOS that is supported on your Mac. Depending on your needs and the apps that you use you may need to get yourself a newer Mac that supports macOS Mojave (10.14) and later. But IMHO you probably have a couple of years (at least) of life left in your current Mac.


Complete iPad backup software without using iTunes, for Windows?

You can use iPad to Computer Transfer (ATTENTION: Direct download link). It's an easy tool which allow you to do exactly what you've asked for. Here is an excellent how-to guide.

And if you're looking for a more solid (and more expensive) solution, you can always try iPad Max.


What happens during the Preparing step is Photos first downloads all the photos/videos being shared (so this step can be skipped on a device that holds full-resolution copies of your photos). You also see this step when trying to share a photo by email or iMessage, with Optimize Storage enabled.

Then it will downsample photos to 2048 pixels on the long edge (5400 pixels for panoramas), and videos to 720p. This step takes place locally, consumes a lot of CPU power, and may take a very long time, particularly with videos. That would explain why you can share a single photo fairly quickly, but then the progress indicator seems stuck once you select everything. I’m almost positive it’s your videos incurring this extra processing time.

Finally, Photos will re-upload everything to a separate iCloud server, which is exempt from your storage quota. However, each shared album is limited to 5000 photos/videos combined, with videos themselves limited to 5 minutes long.

Do note that these steps appear to occur asynchronously. However you’ll still ultimately be bottlenecked by either your CPU or Internet upload speed.

I would advise you to do this from your Mac, if possible. Not only can you leave it plugged in overnight, prevent it from sleeping, and continue using it while it’s doing its thing, the resampling step should be much faster with your Mac’s CPU than with your iPhone’s (generally speaking).

What happens when a distribution certificate expires or revoked?

To answer your questions:

Yes
Yes
Yes

When revoking a distribution certificate the below scenarios will occur for your users:

When you revoke a certificate that means that any app that is not deployed onto a device (not hosted by AppStore) will no longer be valid. Existing users can continue to use the app.
When you revoke a certificate and your App is being hosted on the AppStore; users that have already installed the app will not be affected. New users that go to install the app will not be affected.
When you revoke a certificate and your App is being hosted in-house (internally) and users download it via OTA; users that have already installed the app will not be affected. New users that go to install the app will not be able to install it. Please note this is based off of behavior we have experienced from Apple.
Revoking a certificate will not affect the ability to update existing apps regardless of whether they are AppStore or in-house apps.

Please note that this has been the behavior observed from working with Apple recently and if any updates were made on Apple's end than this is subject to change.


In short, you're stuck.

iTunes will only run in 64-bit mode Since v11 on Mavericks.

That plugin is from 2007, before 64-bit iTunes was even thought of.

Ne'er the twain shall meet, unfortunately.

When downloading in Safari there is significant upstream data, why?

No, Safari is not automatically doing anything like BitTorrent. No need to worry about that.

When downloading a file over HTTP/HTTPS (normally the case with Safari), the system needs to upload as well in order to facilitate the transfer of the file. This cannot be avoided no matter which browser is used.

Normally the internal "house keeping" that is uploaded is small compared to the amount of downloaded data. However, it can vary depending on configuration settings, network circumstances, etc. I.e. for example if you choose to have a low MTU settings, if you have lots of network errors (failures and retransmits), etc. - the amount of upload overhead can be larger than normal.

However 1 MB/s compared to 3 MB/s seems quite excessive. I would investigate further if the upload really stems from Safari or not. Try:

(a) downloading from other sites to see if the effect persists,

(b) download with a different browser than Safari to see if the effect persists,

(c) ensure that you haven't got other programs running that might be uploading, for example a continouus backup program (like Crashplan, Backblaze or similar, or even Time Machine) that simultaneously uploads the downloaded file to your cloud backup or NAS,

(d) if all else fails, create a dump of your network traffic and examine with Wireshark or similar to see what exactly is transferred over the network.


How can I find the PTUUID of a partition in a Linux IMG file on macOS

This answer will omit the path /mnt/hgfs/Downloads/RPi/ given in the OP's question.
The 2021-01-11-raspios-buster-armhf-lite.img file can be download by selecting the Download link for "Raspberry Pi OS Lite" on the webpage Operating system images.
The output from the macOS command file 2021-01-11-raspios-buster-armhf-lite.img is given below.
2021-01-11-raspios-buster-armhf-lite.img: DOS/MBR boot sector; partition 1 : ID=0xc, start-CHS (0x40,0,1), end-CHS (0x3ff,3,32), startsector 8192, 524288 sectors; partition 2 : ID=0x83, start-CHS (0x3ff,3,32), end-CHS (0x3ff,3,32), startsector 532480, 3104768 sectors

This output identifies the file as being an image of a drive using a MBR partitioning scheme. Therefore, the macOS command given below will print the PTUUID. The same command works with Linux.
od -A n -X -j 440 -N 4 2021-01-11-raspios-buster-armhf-lite.img

The output for macOS is shown below.
                 e8af6eb2

Linux will produce the same values, but the padded spaces may be different. For example, the output for Ubuntu Linux is shown below.
 e8af6eb2

Note: This value is not the PARTUUID of a partition on the IMG file given in the OP's question.

The macOS command fdisk 2021-01-11-raspios-buster-armhf-lite.img does a better job displaying the partition table, as shown below.
Disk: 2021-01-11-raspios-buster-armhf-lite.img  geometry: 902/64/63 [3637248 sectors]
Signature: 0xAA55

 2: 83 1023   3  32 - 1023   3  32 [    532480 -    3104768] Linux files*
 3: 00    0   0   0 -    0   0   0 [         0 -          0] unused
 4: 00    0   0   0 -    0   0   0 [         0 -          0] unused

Eventually, the PARTUUID of both partitions is just the PTUUID with the partition number appended, as shown below.

How do I download latest compatible version of an app?

You need to update your iOS version, if possible, or live without those apps.

As of iOS 11, Apple has told developers they must update their apps to 64-bit.  Older, 32-bit, apps can't be on the App Store anymore.

If you're on any version older than iOS 11 and the developer hasn't updated their app (it's the developer's responsibility to do this, not Apple's), you will not be able to download or run the app.


How to backup with Time Machine in Single User Mode?

Problem resolved:

(You will need another mac with a Thunderbolt port to make this work. We'll call the problematic one A and the other one B)

Connect a Thunderbolt cable between the old machine (A) to another one (B).
Start A in target mode (Press T on boot).
You'll now see A's drive as an external drive on B's desktop. Go to 'Startup Disk' in 'System Preferences'. Pick A's drive as your boot disk.
Reboot. If everything's working, you should see A's Finder etc. on B's display.
Connect Time Machine to B. Start it. Click 'Options...' and exclude B's drive from the backup.
Run another time machine backup on the HD.

I eventually went out and got a new MBP (which I was planning to do anyway) and migrated directly from the time machine latest backup.


Move Photos and Videos from an iPhone 4 to PC

You need a way to transfer original photos and videos from your iPhone to your PC. First copy/import them from your iPhone to Windows, then proceed to delete them from within the Photos app on your iPhone.

To copy/import using a Mac, connect your iPhone to your MacBook, and use a macOS built-in app called Image Capture. Upon launching, Image Capture will list your iPhone in the left pane. Selecting it will display all the photos and videos available on your iPhone. Simply select the desired ones and drag them into a folder of your choosing to copy them to your Mac. Once copied, you can also delete them from the iPhone using the Image Capture app.

For computers running Windows, you can download a 3rd party app called iExplorer to easily browse through and transfer all your photos and videos from your iPhone to your PC.

Developers of iExplorer have shared a tutorial article listing instructions on how to transfer photos from your iOS device to PC:

Copy Photos from iPhone or iPod to PC or Mac

Note: No affiliation whatsoever to the developer of iExplorer.

My favorite edit button of safari is missing

You may be a victim of Apple changing functionality of Safari features. Something they do all the damn time. Which can be frustrating when you are used to that functionality. Trying to figure out why Apple does something like this is an exercise in frustration. However...

You can edit your Bookmarks/Favorites under the Bookmarks menu option "Edit Bookmarks"


Outlook 2011 crashing at startup (main window buggy)

Since it works in Safe mode here are some instructions:

1- To check if your user permissions need repair log in as differant user.

If no problem- repair your permissions.

2- This is more detailed one:

If it works in Safe Mode but not in normal mode…

    Remove Login Items. Open System Preferences > Accounts. Click on the Login Items tab. Remove items. You’ll have to test to see which one (s) is the culprit. Verify that you are running the latest updates for all applications. Some might not be Snow Leopard ready.
    Check your Fonts & delete font caches. There appears to be a widespread issue with FontBook and font substitution in 10.6. Something having to do with the fact that Snow Leopard has moved to .ttf as the preferred font library format over .dfont. Office does not need ANY of its fonts to “run.” See Font Management for details and help deleting font caches.
    Check for corrupt preferences.
        Test for corrupt Microsoft preferences. Sort for Microsoft in the User’s Library/Preferences folder.
        Test for other preference conflicts/corruption
            Go into your home folder and take the ~/Library/Preferences folder, and put all the files in there into a folder on your desktop called old_prefs. The Finder will lock up when you move them out the first time. Force quit the Finder.
            Now log out and back in, and you will see your Mac is now back to defaults.
            Test, if it works, you know its one of the preference files.
            Start with putting everything back in that starts with “com.apple” and log out/in.
            Slowly, a few preference files at a time, move the old ones back into place, and log out and back in, then test.
            Rinse and repeat until you find the bad preference.
        If the problem persists, try the same thing with the other sub-folders of ~/Library.
            ~/Library/Caches
            ~/Library/InputManagers
            ~/Library/Fonts (Office 2008 and 2011 no longer use this folder for fonts. You can delete or move to a Fonts disabled folder)
            ~/Library/PreferencePanes
            ~/Library/Application Support
            ~/Library/Application Enhancers


After hard drive upgrade, battery not charging?

If you changed your hard drive appropriately, you would have never touched your logic board, so I would be surprised if it is broke. How did you replace your hard drive? Do the LED-indicators on the battery still work?


MacBook Pro 2011 Unibody 10.7.5 fatally crashes even after recent repair, (lines across screen, graphics glitches, freeze up)

I recently had this issue.  It turns out that Apple has a repair program for this issue at no cost that runs until Dec 31, 2016. Here is the link:
https://www.apple.com/support/macbookpro-videoissues/

I took my laptop in to the nearest Apple Store. The Genius Bar tech ran a diagnostic test to verify the issue.  They sent it to a repair location in Texas and in 3-5 days I had it back.  There is also a 90 warranty on the work.


Yes, newer versions of Bash are released under GPLv3
This question brings out armchair lawyers that argue points for and against GPLv3. Simply put, GPLv3 conflicts with Apple's Licensing Policies (among other licenses). None of these licenses prevent you from downloading the source code and compiling a newer version of Bash. On a historical note, Bash was not originally offered as a shell in OS X.
Apple does not supply any software under the GPLv3 license.

Homebrew + Imagemagick + php54-imagick not working

I have resolved my own issue! Since I was using the readImage method from ImageMagick class, it required ghostscript to be installed alongside ImageMagick.

However, when you brew install imagemagick, ghostscript is an optional dependency that is not installed by default.

To resolve my issue, here is what I did (all the steps):

brew install php54-imagick
brew install imagemagick --with-ghostscript

Now I can readImage('test.pdf')!

How can I use the full resolution of a Macbook Pro Retina 15"?

Go to System Preferences -> Display.
By default, it should have been at full resolution, but if not, then
Select manually the resolution to 2880x1800.


I've had the same issue, starting with a late release of Snow Leopard, and now with Lion. The mouse works fine for a while and then it gets really laggy. Turning the mouse off (disconnecting bluetooth with the computer) and turning it back on fixes the problem, but it has happened at least a dozen times in the past week or so.

I've reported it as a bug to Apple, but it is hard to reproduce. I also have a MacBook Pro with an external monitor. I'm not sure if that is just coincidence, though.


It will do this until you mark it as completed. Think of it this way: unlike recurring Calendar events, a new Reminder is created for every recurrence. They are all "nested" into each other, though, so that effect is not obvious.

For example, if I create a reminder that re-occurs every day called "water plants" it will appear normal the first day. On day two, though, unless I mark day one as "completed", it still thinks I haven't watered the flowers on Day 1, so it continues telling me that I need to water the plants on Day 1. As soon as I check Day 1, it will be marked as completed until Day 2.


Xcode 10 Broke Autocomplete When Inserting Include Names for C++, Any Workarounds?

I can confirm same behaviour on my machine. But you can have the autocompletion for C++ back if you add the include path specified in Build Settings -> Search Path -> Header Search Path. See the picture below.

For all/many C++ projects you may add/modify the Custom Paths in Xcode Preferences-> Locations -> Custom Paths.


._ Desktop and ._Library contain extended attributes for these directories. This StackOverflow question describes roughly what generic ._ files are.

  if for file foo you have another ._foo, and you're on a Mac, the dot-underscore file is where the file resource fork / metadata is kept.

As to why directories like Desktop or Library would need extended attributes is beyond me, though I would guess it has something to do with appearance and special files.

If these ._ files are appearing on a mounted network filesystem (i.e. NFS) that doesn't use HFS+ on the host server, that is because HFS+ would usually store the information found inside these ._ files along with the file itself. However, since other filesystems do not handle these extended attributes nicely, OS X creates a resource fork that allows your client-side HFS+ filesystem to see extended attributes as if they were part of the file itself.

These files are used in the AppleDouble format which cause the file itself and its pesky counterpart to be merged once the file is taken off the networked filesystem and placed onto a HFS+ filesystem. Deleting these ._file metadata counterparts would usually result in their regeneration the next time OS X processes the file itself.

Hitting Play/Pause key (F8) ends FaceTime call

You mentioned in the comment that the music playing app is usually Spotify.

The media keys (Previous, Play/Pause, Next represented by F7, F8 and F9 keys respectively) gets associated with the an app outputting audio/video (if the app is programmed to support it).

If two or more apps are simultaneously outputting audio/video, the keypress is captured by Apple's own built in app (in this case FaceTime).

This explains your observation. In this case, it would be recommended to pause Spotify using it's menu command.

Cant SSH from my mac computer: ssh_exchange_identification

Most of the time it is a server side problem, so check your Raspberry Pi.

Majority of GNU/Linux distributions have /var/log/secure, you can find more data about why connection is closed.

Also check /etc/hosts.deny and /etc/hosts.allow if they are maybe blocking the access. Quick fix can be running this command in shell:

echo 'SSHD: ALL' >> /etc/hosts.allow

Some additional solutions that you can check can be found here http://www.linuxquestions.org/questions/linux-software-2/ssh_exchange_identification-connection-closed-by-remote-host-103423/

recover/restore files with specific extension from Time Machine with OSX

It seems like you will have to use the Terminal:

Mount your Time Machine disk. It will be located in /Volumes/myTMdisk/.
Start the Terminal
Type rsync -av --dry-run --include="*.gif" --include="*/" --exclude="*" /Volumes/myTMdisk/Backups.backupdb/myMac/Latest/myDisk/Users/me/ /Users/me/Desktop/allmygifs/

Replace myTMdisk, myMac, myDisk, me, and /Users/me/Desktop/allmygifs/ with the appropriate values.
You can use the tab key  while typing to auto-complete your path.
If your pathname contains whitespaces or special characters, put it in quotes, e.g. rsync -av --dry-run --include="*.gif" --include="*/" --exclude="*" "/Volumes/Seagate Backup Plus Drive/Backups.backupdb/david914’s MacBook Air/2015-08-30-221221/Macintosh HD/Users/david914/" "/Users/david914/Desktop/allmygifs/"
If you want to restore the files into the original locations, use rsync -av --dry-run --include="*.gif" --include="*/" --exclude="*" /Volumes/myTMdisk/Backups.backupdb/myMac/Latest/myDisk/Users/me/ /Users/me/. I would recommend another backup before doing that. Then replace Latest with the respective timestamp.
In case you get file permission errors (e.g. Permission denied and code 23 error as described here), you may have to use sudo in front of rsync. But now you will really need to backup first. Ideally backup to a different disk or make another copy of your TM disk.

Once you are sure everything works, remove the --dry-run argument after rsync -av to actually write files.
Enjoy!


Free or cheap software to boost volume of Macbook?

I've done some research for you, and I didn't seem to find anything except paid applications, and one that is a half solution. I only found these three (paid) options:
Audio Hijack Pro (free trial, $32 for the full version)

Audio Hijack Pro will allow you to boost your sound pretty easily. Upon opening the application, click "System Audio" in the list on the side:

Then at the top, click "Hijack":  Once Audio Hijack Pro is hijacking your audio, go to the Effects tab and where it says "Click here to insert effect", click and under the 4FX Effect, click Gain.

You'll then have two dials to control the gain. Use these dials to boost the volume.

In my use of Audio Hijack Pro for boosting volume, this seems like a viable solution.

Boom (free trial, $6.99, on sale right now for $4.99)

Boom lives in your menu bar and has a simple slider to boost the volume.

If you click on the  button, you will be presented with an equalizer and numerous other nifty controls:

Hear (free trial, $19.99 for a license)

Hear is a little more complex than the other applications. It is jam packed with features, as you can see from this screenshot:

VLC (free and open source)

I'm not including VLC as a complete solution as it may not work in your specific case. However, it is a half solution.

You may be wondering why I include VLC as a solution. Here's why: VLC boosts the volume of movie and audio files up to 400%. If you open an audio/video file, adjust the volume slider and it will boost the file's volume:

I found some information in the Homebrew docs.

Quoting from under the "Advanced Formula Tricks" section:

  Unstable versions (HEAD, devel)

  Formulae can specify alternate downloads for the upstream project’s devel release (unstable but not trunk) or HEAD

  HEAD URLs (activated by passing --HEAD) build the development cutting

Hopefully this helps with the what.  I can't help with the why.


App Store asks for old Apple ID when installing updates

To delete the application from the Launchpad. Hold down the icon until they all jiggle and the (x) appears. Click that on the app you want to delete, then confirm.
If you do this while the App Store's Updates page is displaying the application, you can then just update!
If not, you will have to download it again. This might mean paying for it again. But if it's family plan eligible, it will show as needing to buy it and you'll have to confirm payment, but then it will inform you that it's family plan eligible and you'll get to download it again for free.
If going through this leaves the app missing from the Launchpad (it did for me one time), then drag the app to the trash (confirming with your password if necessary), wait 10 seconds, and drag it back (possibly confirming again). That should alert Launchpad to its presence.
I hope this helps people in the future. I wasted a lot of time figuring this out, and couldn't find a clue on the web.


How to unlock Sierra Refresh Rate for other resolutions less than 4k?

HDMI 2.0 4K60Hz might use chroma subsampling (YCbCr422 10bpc)
https://www.rtings.com/tv/learn/chroma-subsampling

You can force RGB by overriding the EDID (limits you to 8bpc)
https://www.mathewinkson.com/2013/03/force-rgb-mode-in-mac-os-x-to-fix-the-picture-quality-of-an-external-monitor

DisplayPort 1.2 is preferred because it has slightly more bandwidth and will allow RGB 10bpc without requiring workarounds.

2560x1440@60Hz HiDPI uses a scaled resolution of 5120x2880. This means macOS draws into a frame buffer that is 5120x2880 and the graphics card scales the frame buffer to the scaled resolutions base which is 3840x2160 in your case (SwitchResX can change the scaled resolutions base). By default, scaled resolutions are created with only one refresh rate/timing. I think the timing used for the base resolution is the last built-in timing having the same resolution as the scaled resolutions base. This is why 3840x2160 30Hz is chosen for the timing.

macOS 10.14.6 has a new hidden preference to enable multiple refresh rates for scaled resolutions (including HiDPI resolutions).

sudo defaults write /Library/Preferences/com.apple.CoreDisplay multiRefreshRateScaledModes -bool true

Each scaled resolution (and its corresponding HiDPI resolution) will then have all the timings that the scaled resolutions base has.
https://www.tonymacx86.com/threads/adding-using-hidpi-custom-resolutions.133254/post-1999528

For older macOS versions, I guess you'll need code to create scaled resolutions with specific timings, and patches to CoreDisplay to allow them. Code for some (but not all) versions of macOS that might do that is in IOGraphicsLib.c at opensource.apple.com


Can I use 2 iPads at the same time for synchronized music making? What about with the same app?

This is something that the app itself would have to have supportfor.  There's no support for this inherently in the iPad or in iOS.


Apple ID Password email address is inccorrect but store email address IS correct after restoring iPhone 4S

If an app was installed by someone else (say, a friend or family member) using their Apple ID, you will be required to type in that Apple ID's password to reauthorize the app to your device now that it has been wiped & restored.

If it is a free app it is asking you to authorize, you can also remove the app and re-download through the App Store using your own Apple ID account.


Why won't iTunes stream 320 kbps audio across a network?

Do you know for sure it is the 320 kbps that is keeping the songs from being played? Can you play songs with a lower bitrate successfully?

There are three reasons I can think of that would make a song not play in Shared Library:

You have reached the 5-computer limit
on Shared Library. Only when the
number of concurrent connections gets
back to less than 5 you will be able
to connect and play the songs.
The remote iTunes has not been
authorized for that Apple ID and the
song you are trying to play has DRM
protection (i.e., it is an Audible
book or it was purchased way back
when Apple only sold DRM-protected
songs).
The song is listed on the Shared
Library (and on the "server" iTunes
Library) but it is pointing to a file
that does not exist on the computer's
file system or is out of reach.

I hope this gives you additional ideas to look into.


The iPad charger will take approximately 3x longer to charge than using the standard charger, if your numbers are correct. This may not be fast enough to charge the laptop while you are using it, depending on how much energy it needs.

Try leaving the laptop plugged in while you aren't using it. You can also access the Activity Monitor and go to the Energy tab to get an estimate on how long it will take to charge from the AC.

It is also possible the USB A to C converter you have only supports data transfer and not charging.


What Information Is Gleaned From Conducting An Apple Hardware Test?

As Thecafremo stated in the first answer, AHT/Apple Diagnostics will only show "No trouble found" or provide you with an error code assuming it detects a failure.
Apple Hardware Test (AHT) essentially runs minor stress tests on the major internal components and sensors in your Mac.  The standard AHT test runs quick memory tests, fan tests, Mac wide sensor tests and a very brief hard drive read/write & SMART status test.  AHT also has a checkbox for an extended test, which runs the same tests as before but expands it's memory & hard drive tests, running full pattern tests on RAM and a longer disk scan on the hard drive.  The extended test takes a significantly longer amount of time, 1+ hours compared to 5~ minutes, than the standard test.  While it runs you will hear your different fans spin up to full speed for a few seconds and a progress indicator on the screen tells you what component it is currently testing.  Assuming no failures are found it will present a "No trouble found" message once it's finished.  If failures ARE found then AHT will return a cryptic error code that can be deciphered using the info below, pulled from an excellent CNET article:

4ETH: Ethernet controller
4IRP: Main Logic board
4MLB: Logic board controller
4PRC: Processor
4HDD: Hard disk
4MHD: External disk
4YDC: Video card
4SNS: System sensor
4MOT: Fan motor
4MEM: Memory module
4AIR: AirPort wireless card

The below info, pulled from the same CNET article, can help you isolate specific sensors when the 4SNS error is returned.  The first letter should either be L for current, T for temperature or V for voltage, indicating the type of sensor. The second letter (A, e, M, etc) refers to the component area where the sensor is located.  So, using this along with the info below, we can assume that 4SNS....TH.... error would be the hard drive's temperature sensor.

A: Ambient air sensor
B: Battery
C: Central processors (CPU)
D: DC (direct current)
e: PCI-express slot
F: FireWire port
G: Graphics processor (GPU)
H: Hard disk
h: Heat pipe (heat sink)
L: LCD display
M: Memory or memory riser boards
m: Misc. (i.e., battery chargers)
N: North bridge (motherboard controller)
O: Optical drives
P: Power bus
p: Power supply
s: Palm rests for laptops
W: Airport Wi-Fi card

Apple Diagnostics, available on mid-2013 and newer Macs, runs essentially the same small stress tests as AHT but will return more human readable messages based on it's findings.  If errors are detected it will explain in terms along the lines of "There appears to be a problem with your hard drive" but can still return a cryptic reference code.  Apple Diagnostics gives you the option to reboot to your recovery disk though and to contact Apple's support site for options on resolving any errors found.


How to prevent Terminal window from changing its size after opening and closing tab

The solution is to turn on setting to always show tab bar, even if only one tab is open in window:

in top bar, go to View → Show Tab Bar,
or use keyboard shortcut ⇧+⌘+T.

This is just a workaround I have found on this site to a bug that is present in Terminal app at least since 2009. So far this is the only solution that was working for me consistently on every OS X installation.

Limited Read and Writes on MacBook Air SSD

Flash drives / SSDs have limited read and write capacity, right?

Yes, but it's a calculated value based on a number of factors including, but not limited to:

Duty cycle (how much the drive is being used)
What it's being used for (i.e. more writes than reads or vice versa)
The type of SSD SLC  (Single-Level Cells, used in enterprise applications) or MLC (Multi-Level Cells, used in consumer applications).

When will an SSD fail?

According to this SNIA article, hard drives see a Mean Time Between
Failure (MTBF) of 1 million hours, while SSDs show 2.1 million hours.
SanDisk® further rates its Lightning SAS SSDs at 2.5 million hours
MTBF. Thus, SSDs have more than twice the longevity than HDDs.1

They go on to further differentiate SSDs from HDDs...

SSDs are different in how they wear in comparison to hard drives. Due
to the characteristics of NAND flash, SSDs have a finite lifetime
dictated by the number of write operations known as program/erase
(P/E) cycles NAND flash can endure. The objective of SSD endurance
numbers is to capture this consumable nature of flash storage into a
quantifiable number to provide end users guidance on the anticipated
lifespan for the drive in operation.

Meaning:  It's a best guess number.  Your SSD is not going to stop functioning when it reaches that "theoretical" limit.  Chances are, you are going to outstrip the capacity of the drive with data long before you reach its wear limit; you'll buy a bigger one before it fails.
Just for grins and giggles, I used Intel's SSD Endurance Calculator to estimate the life of an SSD being used for Virtualization with a 100% duty cycle (worst case scenario).
It gave me a life of just under 6 years having written 62 petabytes (62,800 TB).

To put that into perspective2, you would need to

record 213 years, 6 months of full HD video
take 24,000 digital photos per day for the rest of your life

TL;DR
Yes, there's a limit, but you needn't worry about it.  You simply won't be able to perform enough read/write operations before you run out of capacity.
If you're concerned about data loss, you should be doing backups

Change iCloud account alias email address

I just got off the phone with Apple support for this exact question. Short answer: it can't be done.

Once you create an iCloud email account, that account can't be changed or removed from your Apple ID. The only way to delete the email account would be to delete the entire Apple ID account.

Continue using your device and your display will be recorded.
To stop the recording, tap the Screen Recording button once more. The video is saved to your camera roll.

If your device is jailbroken, you can use Display Recorder which performs similar functionality for older versions of iOS.


Why is this playlist copying the wrong songs to my iPhone?

Well, I tried a different tactic. Barring the "Location" criterion, the playlist is basically, "All the 4 and 5 star songs by this set of artists that isn't Christmas music." I have a 4 star smart playlist, a 5 star smart playlist and a Christmas playlist, so I took the time to create a "Headbang Artists" playlist (BTW, 97 artists), and created a new smart playlist that had the criteria of, in "Headbang Artists," not in "Christmas," and in either "4 Star Songs" or "5 Star Songs." This synced successfully.

I'm guessing the other playlist is corrupted somehow and that the duplication of it also duplicates the corruption somehow. But I'll keep it around for a little while in case anyone else knows how to actually fix it in case someone else has a similar problem.


Is there a hand tool for xcode's storyboard (scrolling without scrollbars, PDF style)?

It depends on what type of mouse you're using, but on my magic mouse, I can scroll the storyboard in any direction by dragging one finger over the mouse.

You can also move it around with the command key and arrow keys:

⌘ →   Scroll right

⌘ ←   Scroll left

⌘ ↓   Scroll down

⌘ ↑   Scroll up

Note that you'd have to give the storyboard focus first, by clicking in a blank area.


Terminal script for compare and delete unused Library folder and files

Other options:

Sort ~/Library/Preferences or ~/Library/Containers by modification date
Enable calculating all sizes and sort folders by size in Finder
for f in ~/Library/Containers/*; do osascript -e "app id \"${f##*/}\"" &> /dev/null || echo $f; done
cd ~/Library/Application\ Support; for d in *; do find "$d" -exec stat -f "%m $d" {} + | sort -n | tail -n1; done | sort -n
cd ~/Library/Preferences; find . -name \*.LSSharedFileList.plist -mtime +30 -delete; ls -rt *.plist | grep -v apple | sed 's/^/rm /'


How to set multihoming for download from multiple Wi-Fi connections?

No, it is not immediately possible.

If you had a server that you control in between you and the server you want to download from, it is theoretically possible.

You would install several wireless network cards (or USB WiFi dongles or whatever) in your computer. Setup these up with different IP-addresses.

The server you control (outside your wireless network - i.e. on the Internet somewhere) would download the file for you, edit the received packets to load-balance between your IP-addresses/ports for the wireless interface you have, and send them on to you.

On your computer you would need a special program to receive those packets and reassemble it as a single TCP stream and pass it on to the actual program doing the downloading.

This could more generally be achieved using some sort of VPN software.

However I don't think anything readily available for Mac OS X exists that has this functionality, so you'll have to build it yourself.

All in all, unless you are very interested in networks and computers, it is not easily  achievable.
