Part 1. Why MacBook Pro Keeps Restarting
Mac Pro Will Not Boot
You're wondering: 'Why does my MacBook Pro keep restarting?' The answer is that when you install new software solutions on your MacBook Pro, it can lead to 'kernel panic' (or KP) which leads to unexpected restarts. A kernel panic is really not as scary as it sounds. When your computer's OS encounters an internal fatal error on bootup, and it can't safely recover or continue, it will display an error message informing you that it needs to reboot.
There can be a number of reasons why your MacBook keeps rebooting.
- The most common issue is conflicting applications.
- Another issue could be incompatible hardware or peripheral devices.
- It could be an issue of not enough RAM or hard drive space.
- The plugins or drivers could be out-of-date.
- The system detected a problem and it gives an error message that it must restart to fix the issue.
- If the system is truly stuck in the reboot cycle, the system will shut down.
- In general, a message will pop up on your Mac screen showing you 'Your Computer restarted because of a problem.'
- If you don't have enough free space via virtual or physical memory, your system will lag. You'll see poor performance. You may also see the Kernel Panic issue.
- To check to see if lack of hard drive space is the issue, select the Apple menu.
- To resolve the disk space issue, install a larger hard drive.
- To resolve low capacity hard drive space issues, without installing a new hard drive, delete files or programs to free up space.
- Run a CleanMyMac app to free up additional hard drive disk space.
- You can quickly and easily recover files you've lost by reinstalling the MacOS.
- Recoverit supports the recovery of photos, videos, documents, archives, and more than 1,000 other types of files.
- You can also scan your hard drive and preview the files you want to save before you initiate the recovery process.
