When your MacBook is in sleep mode, it’s turned off but still connected to the power adapter. It draws a minimal amount of power to keep its time and current date settings, as well as other information. When you put your MacBook to sleep by closing the lid, pressing the power button, or choosing Sleep from the Apple menu, it goes into sleep mode.
Recently, some users have reported that their Mac still alerts them of new notifications even when it’s sleeping. This is thanks to the macOS Monterrey’s Focus mode.
If you don’t want your Mac to make any notification sound even after it has been put into sleep mode, here’s how to do it.
How To Turn Off Sound Notifications When Mac Is in Sleep Mode
- On your Mac, go to System Preferences and click on Notifications & Focus.
- Look at the bottom of the window, and you’ll see several universal notifications settings. Tweaking them will override and apply to all notifications on your Mac.
- Under “Allow notifications,” uncheck the following option: When the display is sleeping.
When that option is disabled, your Mac will not play any notification sound when the machine is sleeping.
