You can use the pmset command line utility in Terminal to schedule specific times for your Mac to start up, sleep, restart, or shut down.
In the Terminal app on your Mac, enter a pmset command. Examples:
|pmset -g sched||See the current schedule|
|sudo pmset repeat wake M 8:30:00||Schedule your Mac to wake at 8:30 a.m. every Monday|
|sudo pmset repeat cancel||Cancel the current schedule. I was searching how to stop this routine I have setup long time ago.|
