By default, your Mac will go to sleep after a certain period of inactivity to preserve energy and prevent wear(Mac sleep mode). If you want to change when Mac goes to sleep, you need to adjust the macOS sleep settings. You're usually allowed to turn on/off auto sleep, reduce or extend screen timeout, prevent your Mac from sleeping, and set a sleep timer for your Mac.

On macOS Monterey and earlier, you can easily change sleep settings on Mac from the Energy Saver or Battery preference pane. But macOS Ventura has made certain changes. For instance, you can no longer find the Schedule tab in the new System Settings app in macOS Ventura.

To help you work with your Mac effectively, we'll cover how to change macOS sleep settings on Ventura and earlier releases.

 Note: For the sleep time to work on Mac, you need to ensure that the "Prevent automatic sleeping when the display is off" or "Prevent your Mac from sleeping automatically when the display is off" option is disabled.
