pmset

Question

pmset

Does pmset allow me to enter multiple times to wake mac monterey?

If it does, once entered, how do I get it back in terminal to edit the command or delete what I entered?

I assume the following would work to wake daily at 6a:

sudo pmset repeat wake MTWRFSU 06:00:00

The man page quoted below refers to file locations that I cannot find on the mac, and since it says it modifies the same file that System Preferences Energy Saver modifies, makes me wonder if multiple wake times could be entered.

Many thanks

FILES

All changes made through pmset are saved in a persistent preferences file

(per-system, not per-user) at

/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

Scheduled power on/off events are stored separately in

/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist

pmset modifies the same file that System Preferences Energy Saver modi-

fies.

Conceptually, the OS does support multiple wake schedules - there could be multiple apps on your machine that are configured to wake the machine. The main issue is that there is no user-level documentation on how to configure it.

OMM, at least, the com.apple.AutoWake.plist file does exist. Notably, it contains the following entry:

<key>WARNING</key>
        <string>Do not edit this file by hand. It must remain in sorted-by-date order.</string>

This not only implies that multiple events can be scheduled ("... must remain in sorted-by-date order" doesn't make sense if there's only ever one event), but that you should leave it to the OS to maintain this file.

Typically application developers that are using the scheduled wake will call an Apple-provided API that is ultimately responsible for writing this file. Changes you make may not comply with the API's expectations, and a mistake could lead to unpredictable results. You have been warned :)

Yes, 'OMM' means On My Mac (or On My Machine for those that don't have the benefit of working on Macs :) )

I'm assuming the file is only created when needed - if there are no app-scheduled events then there's no need for the file to exist.

Since there are two files listed in the man page, it seems there are multiple avenues through which wake can be schedule. Maybe pmset is using the other file.

Either way, it doesn't change the fact multiple wakes can be set, there's just not much documentation around it.
