Does your Mac suddenly restart for no reason? It is incredibly frustrating to come back to your Mac and see it mysteriously shut down and restart while you were on the go. If restart issues get bad enough, they can prevent you from fully using your Mac – finding a solution is definitely a top priority! Here are the most common causes of loop restart problems and what you should do to fix them.
Note: Whenever possible, try to save your macOS settings and valuable data to an external drive when you encounter this constant startup problem. Sometimes solutions need to wipe your Mac or some other measure that will lose information stored locally. Before doing any in-depth troubleshooting, make sure your data is safe.
Also, if you have any third-party RAM installed, make sure it is compatible. Some manufacturers like Crucial have Mac-specific RAM that you can purchase to help ensure hardware stability, as incompatible memory can cause serious problems.
MacOS is not updated

Sometimes a missed macOS update or an update problem can cause issues with your Mac settings and the update process. This confuses your Mac and can lead to repeated restarts.
The easiest way to fix these issues is to install all available updates that are compatible with your Mac. You may have to reboot multiple times if you're behind with updates – that's fine! It's just your Mac going through all of the major software changes one by one.
If you can't install the latest macOS software because your Mac is just too old, you should consider upgrading for better performance and stability.
Your software is failing
Sometimes apps you've installed can cause problems. The code is making a request that is not expected by the operating system and / or the underlying hardware, forcing MacOS to restart and resolve the conflict.
This is known as a "kernel panic". When restarting, the message "Your computer has restarted because of a problem" appears. A kernel panic doesn't always mean something is irrevocably wrong with your Mac, but it does mean you may need to make changes. This is especially true if newer software is causing the problem.
First, look at the pop-up message and see if there is a "More Info" button. This doesn't always tell the average user a lot, but sometimes the report will show the name of the software that is causing the problem so you know where to look.
Manually update third-party software, as sometimes that's all it takes to fix an issue. If that doesn't work, remove the latest third-party software and restart it. If removing the software fixes the problem, then you should avoid downloading that particular app until it has been updated by the developer. On the plus side, removing unnecessary software is a great way to speed up your Mac.
Your peripherals are malfunctioning

Another common cause of kernel panic is an accessory or peripheral that is not working properly. This can cause a kernel panic immediately upon startup or within a few minutes of your Mac booting.
Fortunately, this is an easy problem to diagnose. Just remove everything connected to your Mac – including mice, keyboards, drives, etc. If you can restart successfully and your Mac continues to work without incident, you know that one of the peripheral devices is likely to be faulty. Reinstall each peripheral one at a time until you discover the repeat offender.
Your settings need to be reset
Sometimes there is nothing wrong with your Mac itself, but a recent change caused startup issues that caused a kernel panic. If so, your Mac may be trying to restart while it loads. You may not even be able to access anything beyond the login screen.
Often times, you can fix this problem by resetting your Mac hardware settings. This will undo any changes you have made, such as screen or battery behavior. However, it can fix your problem as well.
First, reset your NVRAM or PRAM. The easiest way to do this is to press Option + Command + P + R keys at the same time when your Mac turns on again. Hold these buttons down for about 20 seconds.
Second, reset your system management controller or SMC. There are several ways you can do this, depending on your Mac model. So read the specific instructions for each case.
If these resets solve your problem, your Mac should be ready to use.
MacOS has an error that you need to reinstall
Sometimes minor resets aren't enough to fix the problem. In these cases, the kernel panic is deeply rooted in a native operating system problem and may even be linked to faulty hardware.
Reinstalling MacOS is your solution. The good news is that this should fix any native macOS issue that is causing a kernel panic. The bad news is, your data may not survive. It also doesn't fix any hardware-related issues such as: B. a failed fan causing your Mac to overheat and restart.
Start by restoring macOS, but don't erase the hard drive completely. If that doesn't work, you may need to wipe the hard drive to completely fix the problem. As always in situations like this, make sure to back up any important data that you don't want to lose before you start.
If you still can't get your macOS device working, it may be time to contact an authorized service provider such as the Apple Store or Best Buy and make an appointment.
