It is true that Apple devices are known for their longevity and high quality. However, there comes a point in time when some of their hardware or software fails. So, even if you are in the middle of a business meeting or you are working on a crucial assignment, it is possible that your MacBook turns off all of a sudden.
If ever that happens, don’t panic. You are not alone. In fact, many others have claimed to have experienced similar problems. Just face it. It has already happened. Now, what?
Unexpected Mac OS Shut Down: Why It Happens
Before we discuss ways on how to fix the issue, allow us to discuss a few possible reasons why these unexpected shutdowns happen.
Corrupted OS
Believe it or not, the files that are saved on your device could be the reason your MacBook turns off unexpectedly. Because of a corrupted or damaged file, your device might not be able to find a viable installation of your OS, hence the shutdown.
Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.

Hardware Problems
Does your Mac OS shutdown unexpectedly when in fact you have installed all recent updates? Chances are, it could be caused by a hardware defect. Take note that this problem can be very difficult to diagnose, especially if you have no technical background. Nothing to worry though. It can be fixed.
Battery Defects
Like most devices, without a reliable and dependable power source, your MacBook cannot function properly. So, if there is a defect in your battery, your device can let you down. Thus, you have to literally prepare yourself for these sudden shutdowns.
Basic Fix: Troubleshooting 101
No, we are not suggesting that you buy a new MacBook. We want you to perform a few troubleshooting steps to resolve the problem.
1. Check the power sources.
An unexpected power surge can cause your MacBook device to turn off without warning. Anticipate the same to happen as well if your computer is not connected to an outlet. So, whenever you are working, make sure your device is connected to a reliable power source, or at least, you have enough battery to get you through the day.
2. Inspect the energy saving settings of your device.
Does your Mac OS shutdown unexpectedly every time you go idle for a few minutes? It could be that your Energy Saver setting is set for a very short span of time.
To get it fixed, here are some steps to take:
- Apple Menu > System Preferences > Hardware.
- Click on “Energy Saver”.
- Adjust the time your device is scheduled to turn off when idle or not in use
3. Check for updates.
Outdated software and firmware can cause your MacBook to shut down. Although it was a common issue in the past with some MacBook models, MacBook Pro firmware was released to fix the problem. Therefore, starting today, make it a habit to check for updates and install them right away.
Here’s how to get it done:
- Go to Apple Menu.
- Check the “Software Update” option.
- Install any available update for your OS or firmware.
4. Clear your device from any junk.
As you browse the web, cache files can accumulate. A tool like Outbyte macAries can scan for these and other issues. Ensure the software is a fit for your specific needs.
5. Service your device.
Okay, you did everything, but the problem still keeps recurring. Here’s what you should do. Contact the official support team of Apple on their website or take your device to the nearest Apple service center, especially if it is still under warranty. For sure, they have a certified technician to diagnose the problem and get it fixed.

Whether it’s a new MacBook model or not, you should be able to identify the problem and resolve its random shutdown issue.
