10 Pro Tips to Fix a Mac That Keeps Restarting (2022)

Let’s first dig into the possible causes of the unexpected restart! Once that’s done, we’ll try the various ways and means to get rid of the problem.

What Causes the Mac to Reboot Again and Again?

There are so many things you need to look at when your Mac is rebooting repeatedly. If your macOS device is cluttered for space, it’s the clogged-up storage that may be causing the device to restart. And if you haven’t updated your Mac for a while, there is a good chance that the outdated version of the software may be playing the spoilsport.

Apart from these two usual suspects, you should also never overlook the possibility of the worn-out battery, ill-fated peripherals, and outdated apps. Considering that there are multiple reasons why a Mac restarts unexpectedly, we are going to try several workable solutions. Hopefully, one of them does the trick for you.

Force Quit All Open Apps and Hard Reset Your Mac

At times, you can get rid of a random issue by just force restarting the Mac. Considering how reliable this simple yet effective solution is, it would be worth giving it a try.

  • Click the apple menu at the top left corner of the screen and choose Force Restart

  • after that, select all the open apps and hit Force Restart† Then, press and hold the power button for a few seconds to shut down your Mac.
  • Next, wait for a few seconds and then hold down the power button again to turn on your Mac.

Once your Mac has rebooted, use it for some time to check if the problem has gone.

Note:

  • In some rare cases, your Mac might face a hardware/software issue that requires it to restart. When it happens, an alert will appear on the screen saying something like “Your computer was restarted because of a problem.”

Check Peripheral Devices

Another thing you should do to prevent your Mac from repeatedly restarting is check the peripheral devices such as printers, USB hubs, and hard drives.

  • Turn off your Mac and then disconnect all peripheral devices. If you are using a desktop Mac, keep only display, keyboard, and mouse, or trackpad connected.
  • Now, turn on your Mac and then wait for some time to check if the unexpected restart occurs. If your Mac doesn’t restart, turn it off and then connect one peripheral device at a time.

By re-connecting your peripherals one device at a time, you will be able to figure out which Mac accessory is causing the restart.

Update Apps

If your Mac still restarts randomly, update all apps. If you haven’t updated apps on your Mac for a long time, the problem could be caused by the outdated apps.

  • Open App Store on your Mac and then click the Updates tab. After that, update all apps at one go or do it one by one.

Immediately Delete the Problematic Apps

Whenever your Mac suspects that an app causes the restart, you may see an alert message, “X app may have caused the device to restart. Would you like to move the app to the Trash”

In such a case, click Move to Trash in the popup to get rid of the problematic apps. You don’t necessarily have to do this, especially if the app has only caused the issue once, and it’s a very important app for you. However, if the app is making your Mac restart frequently, you should consider uninstalling it at the earliest.

Reset PRAM/NVRAM (Intel Macs)

No solution as yet? No worries as we still have some viable solutions left for fixing the random rebooting of your macOS device. Now, we will reset the PRAM and NVRAM on your Mac. Since it doesn’t harm any media or data, you shouldn’t worry about losing anything.

Check RAM and Third-Party Hardware

Some Mac models (such as Mac Pro) have user-upgradeable RAM. If you had recently installed memory or a hard disk (or SSD) on your macOS device, ensure that it’s fully compatible and installed correctly.

Use Safe Mode to Isolate the Cause of the Issue

What makes it so handy is the ability to prevent your macOS device from loading certain software when it starts up including unnecessary system extensions, fonts that haven’t been installed by macOS, and login items.

Update Your Mac

If you’re encountering constant restarts on your Mac, and you haven’t updated macOS in a while, make sure you’re on the latest stable version of the operating system.
