Computers normally restart due to various hardware and software anomalies. The problem may be critical or simply due to low memory on your Mac. This article will show you 6 different ways to fix the "Your computer restarted because of a problem" error.

Part 1 - Why Does Mac Keep Restarting Because of a Problem?

Your Mac could be restarting because it has corrupted system files, low memory, or the software you are using has errors. This is quite common, especially when working with older computer models using the latest tools.

The Error Message of "Mac Keeps Restarting"

This error is also referred to as "Kernel Panic" and occurs when macOS detects a problem with your computer's operating. This could be because of faulty software or hardware. You will get a popup warning declaring that "Your computer restarted because of a problem."

There is no need to worry as there are simple ways to deal with this problem.

The Possible Causes of Mac Restart Error.

If you do not regularly update your macOS, you may get Kernel Panic errors regularly. It would be best if you let your operating system update automatically.

Sometimes the error may be caused by the software that you are using. Downloading software from uncertified providers can compromise the integrity of your computer, leading to a "Your computer restarted because of a problem" error.

An accessory or peripheral device that you are using on your Mac can cause the looping restart error. The fix for this is quite simple; switch off the Mac and then disconnect all peripherals on your computer, such as printers, fax machines, mobile devices, etc., and then restart your computer. To find the faulty device, connect them one to isolate the one causing the error.

There are times when the looping restart is caused by deep hardware or operating system errors. One way to fix this is to reinstall your MacOS then see if the error recurs completely. You may also require a hardware diagnostic tool to find out which hardware is malfunctioning on your computer.

When using the login accounts, the mac may run into kernel panic due to small errors when starting the computer. The problem can be resolved by resetting the NVRAM and PRAM. Hold down the Option, Command, P, and R keys simultaneously for about 20 to 30 seconds. Then reset the System Management Controller (SMC), and your computer should be back to normal working conditions once again. Resetting the SMC differs from one Mac to another, so check the process for your particular model.
