Part 2. How to Fix "Mac Shuts Down Randomly"

When your MacBook shuts down randomly, the first thing you must do is reboot instantly and then restart the computer again. This step is essential because programs do not always close properly, especially when you perform a hard shut down.

To restart your Mac, all you need to do is go to the top-left corner of your computer and then from the Apple menu, select Restart.

If rebooting does not help, then it is recommended by Apple to reset your computer's SMC (System Management Controller). It is basically a subsystem of Mac that comes with an intel processor. SMC controls several features like video mode switching, battery charging, LED indicators, sleep and wake, and more.

Step 1: Hold and long-press the power button to shut your computer down. After that, press the power button again to turn on your Mac again.

Step 2: Once your computer turns back on, press Command + Option + Esc to force quit any background applications that are not responding.

Step 3: The final step is to go to the Apple menu and either shut down, restart, or put your Mac to sleep.

Now, if the problem still persists, you can try resetting SMC.

Solution 1. Reset the SMC

Resetting the SMC involves several steps, and it entirely depends on what type of Mac you own and whether it has a removable battery or not. MacBook versions with non-removable batteries include MacBook air, MackBook Pro (2009 versions and later), 12-inch MacBook (2015 versions and later), and the late 2009 MacBook versions.

Additionally, there are different sets of steps to reset SMC on any MacBook with an Apple T2 security chip. MacBooks with T2 security chip usually include the 2018 version and later.

Now, let us have a look at different steps you can take to reset the SMC for different types of Mac computers.

Reset the SMC on a Macbook with Removable Battery:


Step 1: Shut down the Macbook.

Step 2: Carefully unplug the MagSafe power adapter.

Step 3: Remove the battery. If you do not want to do it yourself, go to the nearest Apple Retail Store or Apple Service Center and get it done.

Part 4. How to Prevent Mac From Turning off Randomly

Generally, Macintosh computers last for a long time, but some issues may develop in the long run. Fortunately, you can take several measures for the proper and smooth functioning of your computer. Here are some of the measures you can take to maintain your Mac:

Batteries that are rechargeable do not last for a lifetime. So, it is very crucial to keep a check on your Mac's battery. You should know that the usage of your MacBook's battery is determined through charge cycles. A charge cycle usually happens when you consume all the power of the battery.

Remember, each battery only lasts for a limited number of charge cycles. If you exhaust the total number of charge cycles, you need to replace the battery. To review your MacBook's current battery count follow the steps below:

Step 1: Go to the Apple Menu.

Step 2: Select "About This Mac."

Step 3: Now, choose the "System Report" option.

Step 4: Then, navigate to the subsection "Power" under the "Hardware" option.

Step 5: You will now see the "Battery Information" option — under which you will find the current cycle count.

After following the above steps, if you see that your battery has reached the maximum cycle count, it means you will have to replace the battery. Make sure to monitor your battery regularly to maintain the proper functioning of your Mac.

Reading your Mac system logs on a regular basis will help you troubleshoot problems on your computer and will further ensure that your computer does not shut down abruptly and is in good health.

So, for instance, if you find out through the logs that you are facing low battery issues, you can go to the upper-right corner of the screen, select the battery icon in the menu bar and view the applications using Significant Energy.

Additionally, you can also make use of your Macbook's "Activity Monitor" to view services and applications that use up most of the CPU power.

To open "Activity Monitor," go to the "Applications" and then click on "Utilities." You must pay special attention to the items present under Energy tabs and CPU as they can pose a serious threat to your computer.

To avoid your computer from shutting down in the future, view your Energy Saver settings, which you will find in the "System Preferences" option. You can set your Energy Saver settings to default — this should be enough to save your computer's energy.

Closing Words

Random shutdowns can ruin your work and spoil your reputation. So, if you think your MacBook randomly shuts off over and over without any signs, it is recommended to fix the issue before it causes irreversible damages. Hopefully, the methods mentioned above in this post will help you fix your MacBook shutting down on your own without facing any trouble.
