Even though Apple has a reputation for intelligent and highly responsive software, Mac sometimes doesn’t behave the way you expect it to. Other than the times when overusing causes minor software issues, the laptop also crashes interrupting your work.
Let’s find out why it happens and what can be done to fix it.
Why your Mac keeps crashing
If your Mac has crashed, you’re likely to come across the “Your computer has restarted because of a problem” window on the screen. Usually, Macs freeze when they’re unable to deal with the software installed or the connected devices. In such cases, a Mac might restart to eliminate the issue. But often, the device crashes when starting back up. Sometimes things even get serious and it leads to complete shutdown. Corrupted Kernel Cache is another major reason why your Mac keeps on crashing.
How to fix it
If it’s a Corrupted Kernel Cache issue:
Start in Safe Mode to deal with the Corrupted Kernel Case. Then, reboot your device and check if there are noticeable changes. Starting your Mac in safe mode could resolve startup issues even if your device fails to start. You can do this by following these steps.
Press down the shift key after pressing the power button
Immediately press and hold the shift key after tapping the power button. You should see the Apple icon appear on the screen.
Release the shift key once the login window comes up
Check if the login window shows up, when it does, release the shift key. For Mac devices that are encrypted, you might be prompted to log in multiple times. The first one will be for unlocking the startup disk and the other one to log in to the Finder.
Restart your device normally
To leave the safe mode, start your Mac normally without pressing the shift key down. Observe if it causes any positive effects. If this issue doesn’t pop up again, your kernel cache will be responsible and the safe mode would have fixed the issue for you.
If it’s the corrupted NVRAM
You could check the NVRAM issue in two ways. If you are using a Mac with user-replaceable NVRAM installed and upgraded with a different one than the original, try to reinstall the original and see what happens. Anything you’ve installed needs to match the technical specifications.
Mac’s NVRAM could be reset for resolving crash issues too. if your Mac shows a question mark icon on starting or if it starts from a different disk than the one selected in Disk preferences, resetting the NVRAM could help in many ways.
To do this, press the power button and hold down these keys – P, R, command, and option. Release these keys after about 20 seconds when the Apple logo appears.
The NVRAM resetting process can affect the System Preferences’ settings up to some extent. You might have to adjust these settings. These include display resolution, sound volume, time zone, and startup disk selection. If you are using the Mac with firmware password on, you’ll need to turn it off for the reset option to take effect.
Implement a reinstall from MacOS recovery as it can help. This will install versions, depending on the combination of different keys when starting the reinstall. Follow these steps:
- Turn on your Mac and press down the R, Option, and Command keys on your keyboard. With this key combination, you can install the latest version of MacOS that is compatible with your Mac model.
- Once the Apple logo or a spinning globe (in some models) appears, let go of the keys. The MacOS Utilities window will show up.
- Click on ‘Reinstall MacOS’ from the window. A new window will show up.
- In this window, click the continue button and reinstall MacOS. You’ll get an onscreen instruction to choose your disk or else click on show all disk.
- Select the destination folder and click on restore to start the installation. Your Mac will automatically restart once the installation is complete.
