It can be quite frustrating when your Mac suddenly shuts down and tells you that it "restarted because of a problem." This can be due to a variety of reasons, from a software bug with the operating system to a hardware issue. Fortunately, there are some steps you can take to fix these issues and get your Mac back to working smoothly. Here's a step-by-step guide on how to stop this warning.
Start Your Mac in Safe Mode
Safe Mode starts your Mac by loading only the essential system files and allows you to diagnose problems. To start your Mac in Safe Mode:
- Shut down your Mac and hold down the "Shift" key as you turn it back on.
- Release the button when the Apple logo appears.
- Once the system boots up, you will see "Safe Mode" in the top right corner.
Safe Mode can eliminate problems with system startup. If the problem disappears in Safe Mode, it indicates that the problem may be related to a third-party software or add-on.
Check for Software Updates
Software incompatibilities and outdated drivers can cause these alerts. Make sure your Mac's operating system and installed applications are up to date:
- From the Apple menu, go to "System Preferences."
- Click on the "General" tab and select "Software Update".
- If there are any updates available, download and install them.
Software updates often fix bugs and incompatibilities, which can improve the stability of your Mac.
Check Startup Items
Applications or plugins that run when your Mac starts up can also cause this error. Checking the startup items and disabling unnecessary ones may fix the problem:
- From the Apple menu, go to "System Preferences."
- Select "Users & Groups".
- Click on the "Login Items" tab and check the list there.
If there are unnecessary or unfamiliar items in the list, you can click on them and remove them with the minus (-) sign.
Repair Your Disk with Disk Utility
Errors on your disk can cause these types of warnings. You can try to repair your disk with Disk Utility:
- Open "Disk Utility" from the "Applications" folder.
- Select your main disk on the left.
- Click on the "First Aid" tab and select the "Repair Disk" option.
This process detects and repairs file system errors on your disk.
Perform Hardware Test
If the steps above don't resolve your issue, the issue may be hardware-related. Your Mac's built-in hardware test can identify issues with memory or other components:
- Shut down your Mac and hold down the "D" key as you turn it on.
- Don't release the button until "Apple Hardware Test" appears on the screen.
- Start the test and examine the results.
Errors detected during hardware testing may be a sign of a more serious hardware issue and you may need to contact a professional service.

Reinstall or Reset
If all these steps do not resolve your issue, you may want to consider reinstalling your operating system or resetting NVRAM/PRAM. Reinstalling the operating system can completely fix software-related issues.
- Reinstall macOS: Shut down your Mac, then press "Command + R" while turning it on to enter Recovery Mode. From there, you can select the "Reinstall macOS" option.
- Reset NVRAM/PRAM: Shut down your Mac and hold down the "Option + Command + P + R" keys for about 20 seconds while turning it on.
Conclusion
There are many ways to stop this warning, and the steps above usually resolve common issues. However, if it’s a more serious hardware issue, it may be best to contact an authorized Apple service center. Follow these steps carefully to make your Mac more efficient and trouble-free!
