Why Does My Mac Shut Down When In Sleep Mode?

If your Mac shuts down after going to sleep, it could be a bug or a power-saving setting. Here are some possible reasons:

1️- ) Battery or Power Supply Problems

There are many reasons why your MacBook might shut down while sleeping. If your Mac's battery is low or there's a hardware problem with the battery, the device might shut down when it goes to sleep. If your MacBook shuts down while charging, there's a strong possibility that there's a problem with the adapter or wall outlet.

Solution:

·        Check the battery status by going to System Settings > Battery tab.

·        Try changing your charging adapter and see if the issue persists.

·        Put your Mac to sleep by plugging it into the charger and see if it shuts down.

2️ -) Check out the Sleep Mode Settings!

When your Mac goes to sleep, it can sometimes appear to shut down completely, but it actually just turns off the display and some components go into a low-power mode.

In particular, the following situations may occur:

  • The screen turns off, but the Mac continues to work.
  • External or internal storage drives may stop working when disks are put into sleep mode.
  • When the network connection is lost, operations such as file downloads or remote access are interrupted.
  • If the system disables certain components in power saving mode, the Mac will appear to be completely shut down.

How can you understand this situation?

  • If you notice that when you turn on your Mac after it has entered sleep mode, some applications or processes have stopped, the system may actually be shutting down while it is in sleep mode.
  • If you get an error message like "Mac shut down unexpectedly" when your Mac starts up, it really did shut down.

To prevent this type of shutdown, you can prevent your Mac from shutting down while in sleep mode by changing some options in the "System Preferences > Display & Battery > Sleep Settings" tab.

caffeinate -d

This command prevents your Mac from going to sleep entirely, but this setting is reset when you restart your Mac.
