Schedule specific times for your Mac to start up, shut down, go to sleep, or wake from sleep. You might do this if you want to be sure your Mac turns off when you aren’t working and turns on before you come to work.
On your Mac, choose Apple menu > System Preferences, then click Energy Saver.
Click Schedule in the bottom-right corner, then select the options you want to use.
Schedule a startup or wake time for your Mac: Select the “Start up or wake” checkbox. Choose a day or group of days from the pop-up menu, then enter a time.
Schedule a sleep, restart, or shutdown time for your Mac: Select the bottom checkbox and choose the appropriate option from the pop-up menu on the left. Choose a day or group of days from the pop-up menu on the right, then enter a time.
