How to fix my mac keeps restarting? A Mac that restarts unexpectedly is frustrating. There are a few reasons why your Mac might repeatedly reboot. In this article, we’ll look over methods to identify why your Mac keeps restarting — and, even better, how to fix it.
Why does my Mac keeps Restarting?
The most typical cause of a Mac continually restarting is called “kernel panic.” This occurs when your Mac’s kernel, or operating system, detects an issue that can be fixed by rebooting your computer. You’ll know that this has happened when your Mac shows you a message that “Your computer restarted because of a problem.”
Kernel panic may result from faulty or difficult software, peripheral devices, or hardware settings. Your Mac may also restart because of problems with its operating system. Here’s how to fix the potential causes of your Mac restarting:
MacOS Problems
Missed macOS updates and update problems can confuse your Mac, leading it to repeatedly restart (among other issues). Luckily, this is easy to resolve— simply install all available updates your Mac is compatible with.
To check for macOS updates, enter the Apple menu. Hit About This Mac and then, Software Update. If an update is available, select Update Now.
If updating your software or executing minor resets doesn’t stop your Mac from restarting, you may need to reinstall macOS entirely. This is pretty much guaranteed to fix any issue that may be causing kernel panic. Unfortunately, your data may not survive reinstallation, so ensure you back up all important information before doing this.

Software Issues
In some cases, the root of your Mac’s kernel panic may be applications that you’ve downloaded. When your Mac restarts and the message saying that “Your computer restarted because of a problem” pops up, you may see a “More info…” button. Clicking it may help you identify the individual software causing your problem, so you know where to start resolving the issue.
After you’ve identified the software responsible, check whether it should be updated. In some cases, a simple update is all you need to solve the problem. If that doesn’t help, you may want to remove recently downloaded third-party software entirely. You’ll need to restart your Mac after doing so. If this corrects your issue, you’ll want to keep this app off your Mac entirely (or at least until it is updated).
Incompatible Peripheral Devices
A kernel panic is typically caused by accessories or peripheral devices that are incompatible with your Mac. You’ll know that this is the case if your system restarts immediately or a few minutes after connecting the device (or turning your Mac on with the device connected).
This is an easy issue to resolve. Start by disconnecting all external devices, such as keyboards, drives, and mouse, and restarting your Mac. Connect one device at a time until your Mac claps and reboots. When this happens, you understand that this device is at fault.
The best way to avoid this issue completely is to use only Apple-made or Mac-compatible peripheral devices.
