Can't cancel auto wakeorpoweron repeat schedule via Terminal!

I actually did try that. I used this command: sudo pmset schedule wakeorpoweron "04/15/24 08:00:00" and gave me this error message: pmset: Error in scheduling operation

Any idea what could be causing this?

I have no idea. Try deleting this file: /Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

Edit: I just went through the process of adding, trying to cancel, then deleting the plist. Seems the thing is broken.

You can set a schedule in the past, so you could create one for a date in the past and it should not trigger.

Edit, again:

Try this command, but it is for specific date/time schedules.

sudo pmset schedule cancelall

I can't replicate the error and wonder if it is a problem writing to AutoWake

There is also this plist: /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

If you have it, try deleting it.

Try a PRAM Reset (hold the PRAM Reset for at least three chimes if possible).....Intel Macs only. If you have an Apple Silicon Mac, then you can clear the NVRAM using the following command line making sure to reboot afterwards so the system pulls in the default settings (some settings may not be cleared, such as the computer name):

sudo  nvram  -c

This command also works on Intel Macs.

Try an SMC Reset as well....Intel Macs only.

Try booting into Safe Mode and trying to cancel the schedule. Maybe you have some third party software installed which is interfering with the normal operation of macOS.

Edit: If this is a 2018+ Mac with a T2 security chip or M-series CPU, then you can try a DFU firmware Revive as well which resets the security enclave chip and system firmware. Make sure to have a good backup just to be safe.

How to revive or restore Mac firmware - Apple Support

FYI, you really should post the exact model of your Mac when asking for assistance so we can focus directly on that particular system. You can get this information by clicking the Apple menu and selecting "About This Mac". This information is almost always needed to assist people.

Looks like your commands are correct for cancelling. However, another trick is to download the free app Onyx. In that under utilities is a scheduling menu. From there you can make a startup/shutdown schedule and also cancel all schedules. It will override any schedule you may have entered in terminal. I tested this and it works to remove any schedule you may entered manually using terminal. I would try that if all else fails.

It over rid the terminal command for me. I used terminal to schedule a startup and shut down. I then used Onyx to change the times and it worked. I then used Onyx to cancel and all was gone in terminal (no more schedules). Not sure why it will not work for you.

Apple support was NO help to me! They told me they don't assist with Terminal commands, yet Apple was the one who decided to do away with the system preferences feature.

You should ask to speak with someone with better skills. It’s an Apple support document that directs you to use them.

Try adding a new schedule, then cancel that. You can try a single day with power on at a time it will be on anyway. If you can’t then cancel it, it won’t be problematic.
