How To Schedule Start Up, Shut Down or Restart In macOS Ventura

The ability to schedule power events in System Preferences doesn't exist in macOS Ventura. Instead, if you really need to schedule a repeating shut down, start up, restart or other power event, you can do it using a simple Terminal command.

    I've been shutting my Mac down overnight to save electricity. However, it appears that Apple's XProtect Remediator runs only when the Mac is sleeping. Best to let the Mac sleep for a while before shutting it down for the night.

    William: Not a good idea to shut down. Any energy savings is going to be negated by the extra work your Mac will do during the day to keep up, plus that will slow YOU down while you work too. https://macmost.com/a-beginners-guide-to-whether-to-shut-down-or-sleep-your-mac.html

    Didn't know this existed. Thank you. Very useful.

    With the end of daylight time, I wanted to change the time my Mac came on every day. As I've done before, I went to Energy Saver and looked for the button that does this. After 20 minutes of fruitless searching, I chatted with Apple Support. They eventually took me to the information you presented here, which us where I should have started. Tell me again why Apple changed a simple procedure into a difficult one?

    Mark: We can only guess. Could be they have plans to add it back, but it didn't make the cut for Ventura 13.0. Could be that they are just simplifying the Settings app and they removed some things to avoid bloat. After all, the vast majority of Mac users don't use this.

    I've tried simultaneous restarts on all 4 macs a) to avoid shutting down and b) so the computer hosting the backup drives for all of them can is continuously available. But inevitably the restarts are badly coordinated and the host computer won't restart because one of the other devices is still connected to it. But when I give shutdown or startup commands using the terminal only the most recent command is saved. How to save a shutdown followed a 1/2 hour later by a startup?

    Jim: Not sure. I thought while you can't do multiple shut downs or multiple start ups, you could do on of each. But maybe not. Keep experimenting with it.

    Hello, are you not able to set multiple pmset schedules? I am trying to do a poweron M-F @ 5:30 am and a shutdown at M-F @ 4pm

    Mark: No. Pretty sure you couldn't do that before either. But you should be able to schedule an on and off, separately, Not just two ons or two offs. BUT: Is there any reason you need to do this? Remember it is important to let your Mac sleep. Typical usage is to let it sleep at night, don't shut it down at all.

    Gary, I was able to fine the Sudo CMD I was looking for, which is Sudo pmset repeat shutdown MTWRF 16:00:00 wakeorpoweron MTWRF 05:30:00. I have tried the sleep method on quite a few Mac's and they seem to run a lot worse over time...IMO.

    Mark: Should be quite the opposite. Did you watch that video? Sleep allows you Mac to do maintenance while you are not using it. If you continue to not let your Mac sleep, you'll be slowing it down when you do use your Mac. I highly recommend letting it sleep. If you are having problems, they are probably for some other reason.

    Gary. Have my computer power on timer so like to shutdown before power off, and restart after power returns in the morning.
    Thought I'd followed your commands correctly, but when i check i have odd events showing that aren't mine and when i tried to cancel i received a Parsing Error?
    Time off would be 22:15:00 Time on 07:00:00
    All suggestions gratefully received. Chris W

    chris: Sounds like you have a typo or something in your Terminal command. Look at the examples carefully.

    Here: https://support.apple.com/en-ca/guide/mac-help/mchl40376151/13.0/mac/13.0. Apple says "Your Mac must be awake and you must be logged in for it to shut down at the scheduled time. If you’re not logged in or if your Mac is in sleep, it won’t shut down."
    I want to shut down briefly every night while I'm sleeping, so another Mac to which backup drives are connected can reboot. If I don't shut down the connected computers the host Mac can't reboot. But according to Apple I have to wake up

    the sleeping Mac in order for the terminal shutdown command to work. So that's a wakeup, a shutdown, and shortly thereafter a poweron command, which the terminal won't accept. What to do?

    Jim: Maybe look for a third-party app that does all of that? Is there a reason you want to reboot that other Mac? Maybe a problem you can solve in another way?
