Why MacBook Keeps Shutting Down

It's essential to understand why your MacBook keeps shutting down. Here are some possible reasons:

Overheating

One of the most common reasons behind your MacBook shutting down randomly is overheating. When your MacBook becomes too hot, it automatically shuts down to prevent any damage to the internal components. Overheating can be caused by several factors, including:
  • Running too many applications simultaneously
  • Dust accumulation in the fans and vents
  • Inadequate cooling due to a faulty fan or thermal paste

Hardware Issues

Your MacBook may be randomly shutting down due to hardwareissues, such as a faulty battery or power adapter, defective RAM or hard drive, or a damaged logic board.

Software Issues

Software issues can also cause your MacBook to shut down randomly. These include outdated or incompatible software, corrupted files or applications, and malware or viruses.

Power Management Settings

Another reason behind your MacBook shutting down randomly could be incorrect power management settings. Your Mac may be set to shut down automatically after a certain period of inactivity, or the battery settings may not be configured correctly.

Check your battery:

Boot Into Safe Mode

Apps that load at startup may be problematic. If so, search your Mac's starting drive for faulty file systems. Safe Mode fixes faulty startup disk file systems.

Reset PRAM

PRAM, like SMC, may cause your Mac's unstable behavior. PRAM holds several small preferences. Resetting may fix it. Mac PRAM reset:
  • Turn off your Mac from the main Apple menu.
  • Command+Option+P+R after powering on.
  • Hold the keys until the startup chime.

Reset The NVRAM

PRAM is NVRAM. Older Macs use PRAM, but Intel-based Macs have NVRAM.

Find these apps manually. To choose which app to uninstall, go to the Applications folder and investigate them all. If your Mac randomly shuts down after opening an app, you can uninstall it.
CleanMyMac X, as mentioned before, makes uninstalling questionable programs easier. It includes an uninstaller. More significantly, it removes all connected and remaining files, preventing conflicts following app deletion. Its use
  • Select Uninstaller from CleanMyMac X's sidebar.
  • Click Suspicious.
  • Select and uninstall apps.
