Why Does a Mac Crash?

Your Mac may crash due to several reasons, as follows:

New hardware addition/replacement
macOS update
Software incompatibilities or errors
Low-space on the startup disk
Inadequate RAM to handle multiple apps
Inadequate CPU for handling processor-intensive tasks
Race condition for accessing system resources and storage disk by several apps
Malicious program or virus

How to fix the crashing mac issue?

To fix the crashing problem, go through the following troubleshooting procedures:

A. Run Apple Diagnostics to determine a Hardware Issue

Remove all external devices excluding AC power connection, display, mouse, keyboard, and Ethernet connection.
Restart Mac and immediately press and hold the D key until Apple Diagnostics screen appears.
(If the screen does not appear, then turn off firmware password if any, or hold down Option + D during restart to start the diagnostics over the Internet).
When Apple Diagnostics is aware of your language choice, it displays a progress bar to check your Mac (which may take a maximum of 3 minutes).
When Apple Diagnostics finds any issues, it suggests solutions and displays reference codes.
Opt from the various options:
- Press Command + R or click Run the test again to repeat the test.
- Press Command + G or click Get started to fetch details about service and support options.
- Press R or click Restart to restart your Mac.
- Press S or click Shut Down to shut down your Mac.

When done, you need to Restart or Shut Down your Mac.

B. Boot into Safe Mode to Fix Issues Caused by Any Software

After upgrading your Mac to the latest macOS Monterey, Big Sur, Catalina, and Mojave, if the system freezes or slows down, then restarting your Mac in Safe Mode helps fix the frequently crashing issue.

Safe Mode loads only the important kernel extensions, verifies the startup disk and repairs directory issues (similar to Disk Utility's verify and repair functionalities), prevents startup/login items to launch automatically, deletes cache files, and disables user-installed fonts.

To start your Mac in Safe Mode, do the following:

Restart Mac and immediately press and hold the Shift key until you see the login window.
After the Mac boots into Safe Mode, if no issue occurs then restart it again without pressing any key to start normally.
To know whether you are in the safe mode, open spotlight and type system information.
Use the software section of the system information window to verify the boot mode as Safe instead of Normal.
If the issue comes back in the normal mode, then the login items may be incompatible.
If the Mac does not boot into Safe Mode, then there is low space on the startup disk.
Clean up your Mac's startup disk to allow your macOS to function correctly.

C. Delete Software Update Caches

If your Mac crashed during the auto software update, then you must clean the following files:

/Library/Preferences/com.apple.SoftwareUpdate.plist
/Home/Library/Caches/com.apple.SoftwareUpdate/
/Home/Library/Preferences/ByHost/com.apple.SoftwareUpdate.123.plist

D. Use First Aid of Disk Utility to Fix File-System Issues on a Drive

Disk Utility's First Aid has the option to repair and verify your start-up and logical disk. To fix the crashing issue, perform the following steps:

Restart Mac then press and hold Command + R keys until you hear a chime

1. In Recovery Mode, open Disk Utility.

2. Select the startup disk and click First Aid << Run.

3. Allow Disk Utility to repair the drive.

When the repair task is over, the crashing issue probably is fixed.

E. Reset NVRAM

Resetting the NVRAM can also fix the startup issue. To reset NVRAM, do the following:

Restart Mac then press and hold Command + Option + P + R keys after you hear a chime and release the keys once you hear the second chime.

This will reset the NVRAM and hopefully fix the crashing issue.

F. Uninstall Incompatible Apps

If the crashing issue persists, then you need to single out the app that is causing the trouble. Uninstall the recently installed third-party app. To uninstall the app, do the following:

Go to Finder > Applications
From the applications folder, find the app you want to uninstall
Drag and drop the app to Trash

If the issue is not fixed then continue the process of uninstallation.

G. Reinstall macOS

If the crashing issue persists, then the only option left is to reinstall macOS. To perform the reinstallation task, do the following:

Restart Mac then press and hold Command + R keys until you hear a startup sound to enter the Recovery Mode.
Under macOS Utilities, click Reinstall macOS and then Continue.
Act as per the on-screen instructions then opt for the startup disk and click Install.

Once the reinstallation process of macOS is over, you will not face any crashing issue.

Warning: Before performing the macOS reinstallation process, backup your Mac to an external storage drive.

H. Frequent macOS crash may lead to data loss, and that's worrying

Hard drives and SSDs are vulnerable to frequent crashes. The storage drive may fail partially or die without warning. Further, file system errors and kernel problems may lead to data loss and turn the storage drive inaccessible.

The default solution is to boot Mac safely into Recovery Mode and restore your latest backup by using the Time Machine.

However, if you have no Time Machine backup, then a data recovery Mac utility is a must to recover the lost data.
