Scheduling Auto Restarts on MacOS Devices

How To Use the Energy Saver Preference To Schedule Mac Restarts and More.


Yesterday, I showed you how to Restart and Hard Reboot your Mac and mentioned the value of restarting your Mac every week or so to ensure smooth operation.

Here’s how you use the Energy Saver preference to schedule Restarts, Shut Downs, Start Ups, Sleeps, and Wakes.

Scheduling Restarts, Shutdowns, and Sleep
(When your Mac is connected to power.)

  1. Open System Preferences.
  2. Click on Energy Saver.
  3. Click the tab for Power Adapter.
  4. At the bottom, click Schedule.
  5. You’ll see two check boxes, check the bottom one and choose Restart (or Sleep or Shut Down—you can set schedules for all three of these.).
  6. Next, choose when you’d like to have Restarts occur (schedule for a time when you’re not regularly busy to avoid an interruption). I have my Restart set for 3:00 a.m. every Friday.

    1. Your Mac must be awake and you must be logged in for it to restart or shut down at the scheduled time. If you are not logged in or your Mac is in sleep, it won’t shut down or restart.
      Workaround: Schedule your Mac to Wake (see below) five minutes before your scheduled Restart or Shut Down.
    2. Also, if you have any documents open with unsaved changes, your Mac might not go to sleep or shut down when scheduled.
      Workaround: Use Autosave in as many applications as you can.

Scheduling Start Ups and Wakes
(Use these options if you already have your Mac scheduled to Sleep or Shut Down.)

  1. Follow Steps 1–4 above.
  2. In the Schedule window, check the top box  Start up or wake.
  3. Choose the appropriate days and times prefer based on any scheduled Restarts, Shut Downs, or Sleeps.

Battery Options
I do not recommend setting any Schedule options for the Battery tab.
