Can NotchStar sleep or shut down your Mac on a timer
NotchStar cannot sleep or shut down your Mac when a timer ends. The Timer, the Stopwatch and the Pomodoro only count and, at zero, play a sound. They do not run a command, pause playing music or touch your power settings.
What a timer does at zero
It plays your chosen sound once and resets. That is all. See what happens when a timer ends.
If you want a Mac to sleep or shut down later
That is a job for macOS itself, not for a notch app. Look in System Settings for the display and sleep options, or choose Sleep or Shut Down from the Apple menu yourself. The names of the settings differ between macOS versions, so check the one on your Mac.
Using NotchStar as a reminder
You can still use the Timer as a prompt. Set 45 minutes, and when the sound plays, close the lid or choose Sleep from the Apple menu yourself. The alert is only a sound.
Limits
- No actions at the end of a timer.

The feature is described on the Timers page.
