I use terminal to auto shut down and start up each day. here is an overview:
Using Terminal to set start up and shut down each day
Separately:
Shut down each day at 9:30 pm:
Sudo pmset repeat shutdown MTWRFSU 21:30:00 and hit return
Enter PW if required
Startup every day at 6:00AM:
Sudo pmset repeat wake MTWRFSU 6:00:00 and hit return
To have both startup and shutdown:
Sudo pmset repeat poweron MTWRFSU 6:00:00 shutdown MTWRFSU 21:30:00
To check if these were set:
Pmset -g sched
To cancel all settings:
Sudo pmset repeat cancel and hit return
