MacBook unexpected shutdown and restart

MacBook Pro, MacBook Air, or a new MacBook, you might have to deal with an issue called “Unexpected Shutdown”. This MacBook problem can be really annoying because your computer will restart itself without any reason. The best way to solve this problem is to get a repair service or to make sure that your software is up-to-date. 

If you’ve been using a MacBook Pro, MacBook Air, or new MacBook and suddenly it restarts itself without any warning, you may be experiencing the “Unexpected Shutdown” issue. It’s a frustrating problem that can often be solved by making sure your software is up-to-date or by getting a repair service.

One common cause of the Unexpected Shutdown issue is outdated software. If your system software is out of date, it can lead to instability and unforeseen shutdowns. To check for updates, open the App Store on your Mac and click the Updates tab. If any updates are available, install them and restart your computer.

Another potential solution is to reset the SMC (System Management Controller) on your Mac. The SMC manages power delivery to different components in your computer, so resetting it can sometimes fix issues with unexpected shutdowns. To reset the SMC on a laptop with a non-removable battery:

* Shut down your computer *completely*. Don’t just put it to sleep – make sure it’s turned off all the way.

* Press and hold the left Shift + Control + Option keys along with the power button at the same time for about 10 seconds until you see an LED light flash or hear a startup chime (this means that the SMC has been reset).

* Let go of all four keys at once then turn on your computer as usual.

On some Mac laptops with removable batteries (like older models of MacBook Pro), you’ll need to follow these steps: 

* Shut down your laptop

* Remove its battery

* Press and hold both the power button AND volume up/down buttons for 10 seconds OR press and release each key three times in succession if you don’t have access to both buttons simultaneously For more detailed instructions specific to your model of Mac laptop, Apple has outlined how to reset various types of SMCs here​. After taking these steps, hopefully, your unexplained shutdowns will become a thing of past!
