On your Mac, you can control exactly how long you spend inactive before your display and other components go to sleep. Here's how to adjust your Mac's sleep time.

How to set sleep time on Mac

In Mac system settings, you can choose how long the display waits before going to sleep. You can choose anywhere from one minute to three hours, or you can choose to have the display never sleep unless you manually put it to sleep. The steps vary slightly depending on which version of macOS you're running and whether you're using a laptop or desktop.

What is the purpose of putting Mac to sleep?

Just like your phone, one of the biggest battery drainers on your Mac is the display.
