The question why do MacBook Pro/Air, iMac, and Mac mini permanently crash pops up on the Apple support community pretty often. Very few Mac users manage to keep calm when a ‘spinning beach ball of death’ appears on their Mac’s screen. Even worse, macOS Sierra/High Sierra can get stuck on the ‘grey screen of death’ after routine updates. In spite of having a bulletproof reputation, Macs do freeze and crash sometimes, so you have to know how to handle these issues. Read on to learn step-by-step troubleshooting instructions for all possible situations.

Macs can crash for a variety of reasons, which is why each particular situation needs separate troubleshooting activities. However, the typical reasons causing Mac crashes are as follows:

Malware/virus infection which infiltrated a Mac through third-party apps;

Insufficient RAM for applications to run properly;

Insufficient CPU capacity for resource-intensive programs;

Several apps are competing for disk access and system resources.

How to fix the Finder app that keeps crashing on your Mac? The best option is deleting potentially corrupted Finder system preference files with .plist extension:

  1. If the Finder app still launches in spite of crashing, open the Finder window.
  2. Go to Home -> Library -> Preferences.
  3. Find and remove these files:apple.finder.plist and com.apple.sidebarlists.plist.
  4. Log out, and log back in.
  5. Empty the Trash.

Alternatively, you can use the Terminal app to remove the files, if Finder won’t launch.

  1. Run the following commands:

rm ~/Library/Preferences/com.apple.finder.plist, then press Return.

rm ~/Library/Preferences/com.apple.sidebarlists.plist, then press Return.

  1. Log out, and log back in.
  2. Empty the Trash.

One of the most frequent issues with MacBook Pro is related to random crashes known as ‘kernel panic.’ These crashes may occur after hardware replacement or software updates. To identify what’s causing the problem, run Apple Diagnostics (or, Apple hardware test on Macs manufactured before 2013).

1.Unplug all external devices (keep the keyboard, mouse, monitor, Ethernet connection, and AC power plugged). Apple Hardware Test might show an error message if other devices are not unplugged.

2. Turn off your Mac, and turn it on again holding the D key while it is booting. Wait until the Apple Diagnostics screen (Apple Hardware Test icon) shows up:

3. If you’re running the Apple Hardware Test, choose the language by pressing the ‘up’ and ‘down’ arrows, then hit the Return key to confirm. Apple Diagnostics performs the further steps automatically.

4. Next, click the Test button (T key) or Return to begin testing. Running an in-depth test needs a bit more time to complete. Select Perform extended testing before the test begins.

5. Once the test is over, you can see the results in the bottom-right part of the window.

6. To exit the diagnostics, click Restart (R key)/ Shut Down (S key) in the lower part of the window.

“A Mac update crashed my computer!” is another frequent plea for help on the Apple support community. Users know that installing Mac OS /software updates is the best way to keep their Mac protected. Still, many users have experienced crashes in the middle of a system upgrade. On older Mac models, upgrading to macOS Sierra on top of OS X El Capitan caused slow work and freeze ups. To fix the issues caused by upgrading to the latest Mac OS, you can do the following:

restart your Mac in a Safe Mode and disable the antivirus software (especially if you’re using third-party antivirus software);

switch to another Wi-Fi network

try downgrading to the previous Mac OS version


perform a clean install of the new operating system

If your Mac crashed during the automatic software update, find and delete the following files:

  • /Library/Preferences/com.apple.SoftwareUpdate.plist
  • /Home/Library/Preferences/ByHost/com.apple.SoftwareUpdate.xyz.plist (“xyz” is a number).
  • /Home/Library/Caches/com.apple.SoftwareUpdate/ (purge the entire folder).

Alternatively, use a Time Machine backup to revert to the previous state.

If you use one of the earlier Mac OS X versions, follow the below instructions to fix freeze-ups and system crashes. Choose an option depending on the severity of the problem:

  1. Try rebooting your Mac in a Safe Mode. For this, hold down the Shift key while restarting your computer until the Apple logo appears. If the startup fails, most likely you don’t have enough free space on your startup disk.
  2. Try resetting the NVRAM. For this, restart your Mac and press down the Command-Option-P-R keys altogether after hearing the start-up chime. Release the keys after you hear the startup chime for the second time.
  3. Boot into the Recovery Mode. For this, restart your Mac holding down the Command ()-R key combination after hearing the start-up sound. Check your hard drive for errors using the Disk Utility.
  4. If the problem persists, reinstalling Mac OS X from scratch is your best option. First, reboot your computer into the Recovery Mode. In the OS X Utilities menu, select Reinstall OS X, then click Continue.

Note: reinstalling OS X on top of the current system does not delete your files and settings. However, this may help in fixing some system-wide issues.

If your Mac crashes several times in a row, it is crucial to single out the problem. Find out if a particular application is a reason, or the entire operating system is affected. In the first case, you will get an application crash report with comments. To fix the issue, click Reopen to relaunch the app, or click OK to quit the alert window.

If the problem stems from the macOS itself, there can be a plethora of reasons causing it. Try the below steps to eliminate the issue:

  1. Reset the SMC (System Management Controller). Unplug all accessories before resetting. Press and hold down the Power button for 10 seconds to turn off your Mac. Disconnect the AC adapter and wait 15 seconds, then plug the power cord back in and switch on your Mac in 5 seconds.
  2. Reboot in Safe Mode. Restart your Mac while pressing down the Shift key after you hear the start-up chime.
  3. Reset NVRAM/PRAM. Restart Mac while holding down the Command-Option-P-R key combination.
  4. Uninstall third-party apps, plug-ins, antivirus software, PPTP VPN software, which may be incompatible with the current macOS version.
  5. Clean up your Mac’s startup disk to ensure there is enough space for macOS to operate properly.

Mac crashes can stem from different reasons, which signal about serious application or system-related issues. Isolating and identifying the problem is the best way to single out all possible causes. To prevent your Mac from occasional freeze-ups and crashes, use the latest Mac OS and software compatible with your machine’s hardware. macOS High Sierra is the recommended version of the operating system to date. Upgrade to the latest stable version to maximize your macOS experience.

Why is Mac Mail not working?

With a new macOS out there, some Mac users have encountered Mac Mail problems following an attempt to update to macOS Catalina.

If you are experiencing any of the problems listed below, we’ve got fixes to get your Mac Mail working as it should. Despite numerous improvements from the previous operating system, there weren't too many changes made to the Mail App in Catalina.

However, there have, and were numerous reports of the app crashing or unexpectedly quitting, which is why fixes and workarounds are currently needed to ensure the Mail app works as it should.

Here are a number of problems and 12 fixes for those who've encountered unexpected issues with Mac Mail.

1. Mail not launching since macOS Catalina update

This is one of the most common problems people keep encountering, and it seems the fix is pretty simple too.

Fix: Launch the Mac Mail app from your Applications

If Mail launches that way, drag the icon out of the Dock. Once that has vanished, drag the icon — a copy of it will be made —back into the Dock. Then close Mail and attempt to open it again via the Dock. Providing that works, your problem is fixed.

Tip: Control + Click the Mail app icon to reveal 'Open' command in the context menu.

2. Mail crashing or running slow

Now, if the above solution doesn't work and Mail is either crashing or running slowly, there are other ways you can get it working smoothly again. No one can be without access to email for too long!

Fix 1: Force Quit the Mail app

Do this the usual way, and if that doesn't work, move onto the next step.

Fix 2: Restart Mail using the Activity Monitor

  1. Go to Activity Monitor through Spotlight, Siri or Utilities.
  2. Type ‘Mail’ into the search function.
  3. Now click on the X symbol to force close.
  4. Attempt to restart the usual way - or take it out of the Dock and put it back in (fix #1), before trying to restart the Mail app.

Fix 3: Delete saved Mail states

If the solutions above don't work, let’s start to clear out some prior-state files on your Mac.

This requires going into your hidden Library folders.

  1. Open Finder > Go to Folder...
  2. Now hold the Option key and Select Library to open these folders.
  3. Find this folder: Containers > com.apple.mail > Data > Library > Saved Application State
  1. Within that, move this folder into Trash: com.apple.mail.savedState
  2. Empty the Trash and try to restart Mac Mail the usual way.

Important: Back up the mentioned folder so you can put it back if something goes wrong.

If that has worked, you can restart Mail and it should be running smoothly. If not, there are other solutions below, and some that don't involve quite so much digging within Library folders and files - which aren't always so easy to find for those who aren't Mac power users.

3. Mail folders missing

In some cases, these problems have caused Mail folders to go missing - without those the app won’t work, so there are solutions to these that most users can manage without too much difficulty to get the Mail app working again.

Fix: Check your Mail Connections

  1. Open the Mail app.
  2. Go to the Window in the top menu and click on Connection Doctor.
  3. This will show whether there are problems with connecting to the Mail app.
  4. Now re-check account settings and delete and re-add your Mail account to reset this.
  5. Your Mail app and every email should be accessible again.

4: Mail app is slow

Sometimes your Mail is slow because it has to deal with tons of open windows buried beneath other apps.

Fix: Merge Mail windows

Specifically for this your email client has a lesser-known command called 'Merge All Windows'.
Click on Mail > Window
Now, choose 'Merge All Windows'
Close the redundant windows to minimize the impact on your Mail's memory. Hopefully, it will get snappier.

5: Mail app junk

As outlined above, there are a number of fixes for Mail not working. Some of them require a certain amount of technical confidence and know-how.

Fix 2: Reset the Mail App (nuclear option)

One of the quick fixes that works in 99% of the cases is to “reset” the Mail App. I use CleanMyMac X for this operation. It doesn’t delete the program itself but brings it back to its default state. This operation solves many app conflicts and incompatibilities. Also, your user files stay safe and are not being affected.
