What to Do When Your MacBook Keeps Shutting Down?

Nothing is more annoying than having your Mac unexpectedly shut down, especially when you’re in the middle of something critical. In most cases, it is a one-time occurrence that never occurs. If you see your MacBook keeps shutting down repeatedly without warning, you should investigate the cause and look for tips and tools to help you fix your MacBook.

We’ll walk you through the steps to stop your MacBook from shutting down randomly in this guide. So, without further ado, let’s get started.

Why Does My Mac Keep Shutting Down Repeatedly?

Does your Mac keep shutting down for no apparent reason? It’s both disappointing and frustrating to return to your computer and discover that it has randomly shut down and begun rebooting.

If the restarting issues worsen, you may be unable to use your Mac, so finding the right solution should be your top priority. Here are some common causes of Mac shutting down at random:

Outdated macOS

Forgetting to update your macOS or another update flaw can cause problems with the update process or Mac settings. This can confuse your Mac and cause it to restart or shut down completely.

Your Software Is Causing an Error

Many times downloading third-party applications can cause your Mac to shut down. This typically occurs when a software bug enters your operating system or when two or more specific applications run concurrently while most of the memory is in use.

Your Peripheral Devices Are Causing a Problem

Apple suggests that a common cause of your Mac keeps shutting down is a peripheral device or accessory, such as a keyboard, mouse, or drive, that is not working properly. But, again, this issue is simple to identify. Simply disconnect every device connected to your computer and see if your Mac restarts and operates normally.

7 Methods to Fix Your MacBook Keeps Shutting Down Randomly

Whether you have found the reason for your MacBook’s random shutting down or not, the one thing you will be looking forward to is how to fix this random shutting down problem. Here are some of the methods that can assist you in resolving this issue.

Method 1. Complete Shutdown

Most Mac users never put their machines down. They just put it on sleep mode for fast boot-up. Usually, this is not an issue, but a complete shutdown can clear the temporary glitches and fix your problem when your Mac keeps shutting down on you. Here’s how you can completely shut down your Mac:

Step 1. Hold and long-press the power button to shut down your computer. After that, press the power button once more to restart your Mac.

Step 2. After restarting your computer, press Command + Option + Esc to force quit any background applications that are not responding.

Step 3. Finally, go to the Apple menu and choose whether to shut down, restart, or sleep on your Mac.

Method 2. Reset Your SMC Settings

Resetting the SMC entails several steps entirely dependent on your Mac type and whether it has a removable battery. MacBook Air, MackBook Pro (2009 versions and later), 12-inch MacBook (2015 versions and later), and late 2009 MacBook models all have non-removable batteries.

Furthermore, different steps are required to reset SMC on any MacBook with an Apple T2 security chip. MacBooks with T2 security chips are typically from 2018 and later.

Let’s look at the various steps you can take to reset the SMC on numerous Mac computers.

Method 3. Cool Down Your Mac

If heat builds up inside your Mac, it can shut down your device to protect its internal components. In most cases, improper machine placement will result in a random shutdown. To allow proper airflow, MOU recommends that you keep the laptop on a flat surface.

To avoid blockages, you should clean the air vents with compressed air. Also, as a precaution, we recommend you not use MacBooks in temperatures above 95 degrees.

Method 4. Update Your macOS

A bug in the Macintosh operating system is most likely causing your computer to shut down randomly. To avoid such issues, keeping your macOS up to date is critical.

To update your Mac, go to the menu bar, select “Apple Menu,” and select “About This Mac.” Finally, select the Software Update button and let your computer check for updates. If any updates are available, they will begin downloading and installing them right away. This step may instantly resolve all of your Mac keeps shutting down errors.

Update macOS

Method 5. Reinstall Your macOS

If you’ve exhausted all of the methods and updates for restarting your computer, the next step is to reinstall Macintosh Operating Software. Reinstalling macOS can resolve all issues preventing your computer from functioning correctly. However, before you begin the reinstallation process, make a backup of your data and then erase your startup disk.

You can find detailed instructions on how to reinstall Macintosh software on Apple’s support page.

Method 6. Reset Your PRAM

Resetting the PRAM is the next solution you should try when your MacBook keeps shutting down. PRAM, also known as parameter ram, could cause your MacBook to shut down automatically. You should try resting it to correct any errors it may have caused.

The simplest method is as follows:

Reset Your PRAM

Step 1. Turn on your system.

Step 2. Press the “Option + Command + P + R” keys at the same time.

Step 3. Hold them down for 20 seconds.
