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.

• Using outdated MacOS

  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.

• Software-related errors

  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.

• Faulty peripheral devices

  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.

• Deep-rooted errors

  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.

• Login issue

  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.

The steps listed below will help you identify and solve hardware and software issues that cause Kernel Panic in Mac.

Solution 1 - Identify and update malfunctioning software

Outdated software is prone to creating errors such as Kernel Panic. Updating it will solve the problem.

1. Carry out software updates on your Mac
2. Restart your Mac
3. If you cannot update the software, uninstall it, or use a third-party software uninstaller to remove all problematic software instances. Reinstall the software once more.

Solution 2 - Reset disk permissions

This resets all system file use on your Mac.

A) For OSX Yosemite and older versions

1. Hit "Cmd + R" to restart the Mac.
2. Open the Disk Utility feature.

3. Now choose "First Aid," followed by "Repair Disk Permissions."

B) For macOS Sierra or OSX El Capitan

1. Launch CleanMyMac X.
2. Choose the Advanced Maintenance option.
3. Complete repairing the disk permissions.

Solution 3 - Free up disk space

Ideally, you should have at least 20% of your total disk space free to kernel panic. This is due to having low physical and virtual memory, which your Mac needs to run efficiently.

1. Go to the Apple Menu and choose "About This Mac."
2. Click on the "Storage" tab to see how much free storage you have.
3. If it is low, then you need to delete unnecessary files, such as pictures or videos.
4. You may also run CleanMyMac X to free up more space.

Solution 4 - Use the Disk Utility feature

Disk utility is a nifty inbuilt feature used to fix errors on your Mac.

1. Click on the Apple menu and then select "Restart."
2. Immediately hit the "Cmd + R" keys on your keyboard once the Mac restarts.
3. Now click on "Disk Utility." And choose "First Aid."
4. Follow the on-screen prompts to find and fix errors on your Mac.

Solution 5 - Disable unnecessary startup items

At times, some startup tools which you do not need serve to clog up your Mac processor. This may make it sluggish, leading to a "Your Computer restarted Because of a Problem" error.

1. Select the Apple menu and then go to "System Preferences."
2. Choose "Users & Groups" and then choose your user account from the list.
3. Now click on the "Login Items" tab to get a list of startup items.
4. Choose the startup item that you want to stop and then select "-."
5. Now restart your Mac, and the kernel panic issue will be solved.

NOTE: To determine which startup program is causing the kernel panic, you should disable each one at a time before rebooting the Mac. Sometimes the problem may be due to a single item, which means you do not have to disable all of them.

Solution 6 - Repair corrupt MacOS files

At times, the kernel error is caused by corrupted MacOS files. The only way to fix this issue is to reinstall the macOS version that you are using.

1. Shutdown and restart your Mac and then Hold the "Cmd + R" keys to enter the "MacOS Utilities" feature.
2. Now select "Reinstall OS X" or "reinstall MacOS," depending on the version you are using. Once the OS has been reinstalled, restart your computer once again.

Part 3 - Learn and Fix Different Mac Computer Restart Errors

Mac can present you with different errors when you restart or reboot the system. Here are some rare Mac restart issues and what you can do to resolve them.

1) Mac stuck on Loading Screen

This occurs when your Mac cannot progress beyond the loading screen. Any of the following may cause this:

• A stacked SMC or PRAM component
• Missing boot resources
• Damaged Harddisk
• Virus infection
• Outdated OS

Fix this issue by using "terminal" to check your file system. You must first reboot into Mac in "Recovery Mode."

1. Restart your Mac and hit the "Cmd + R" keys.
2. Go to "Menu > Utilities" and then click on "Terminal."
3. Finally, type in "/bin/fsck -fly" and then hit enter.

2) Mac stuck on Green Screen

This occurs when you start your Mac, and instead of progressing to the desktop, you get a blank green screen and nothing else.

This may be caused by

• Faulty hardware, firmware, or bootloader
• Not enough space on your Mac
• Virus infection
• Missing screen drivers

To fix this issue, you should start by deleting the Trash Bin and Cache to free up space. Start by rebooting into safe mode and then cleaning up these locations and any other unnecessary files.

1. Restart your Mac and hold the Shift key to reboot in "Safe Mode."
2. Enter the admin account; select the Trash icon in the dock and then right-click followed by "Securely Empty the Trash."

3. You may also use the Finder and navigate to "Library > Caches." Empty the cache to free up space.

3) Mac Frozen Screen

This issue is different from the Green Screen in that it refers to occasions when the screen will freeze even when you are using the Mac normally after booting properly.

This may be caused by:

• Faulty software
• Faulty peripheral devices
• Hardware problems

You can fix this issue by going through several channels.

1. Force restart the Mac by continually pressing the Power button till it goes off.
2. Disconnect all peripheral devices and see if the screen will unfreeze.
3. Reboot into safe mode by holding the shift key when starting the Mac.
4. Reset the PRAM by pressing the P, R, Option, and Command keys at the same time when you restart the Mac.
5. Use disk utility to repair the disk.

1. Start by launching Recoverit Mac Data Recovery.
2. Choose the location that you want to scan.
3. Preview the files and then save them to a different location on the disk or external disk.

Part 4 - How to Prevent "Mac Restarted Because of a Problem"

1. The Normal Process of Restarting Mac Computer

There is a correct and incorrect way of restarting your Mac. If you do not want to damage your hard disk or corrupt the boot files, use the methods below.

• Choose the Apple + restart.

  Click the Apple Menu and then select restart. This is the simplest method of restarting your computer, and it is normally safe.

• Use the "Power" button (or use Control + Eject)

  Use this when the screen has frozen up, and you cannot access the Apple Menu. This will cause your Mac to Hard Reboot and may lead to some data loss.

• Use the Control + Command + Eject (or Control + Command + Power) buttons

  Once again, this method is used when the screen has frozen up. It does not rely on the macOS operating system and is therefore safe since it will not affect the files required for a proper restart.
