Auto-Shutdown with APC UPS Does Not Work on M1 Mac Mini (Monterey 12.2.1)
Energy Saver Auto-Shutdown options with an UPS are not working on my M1 Mac Mini running Monterey 12.2.1 with APC Back-UPS BE860HG2.
We need the M1 Mac Mini to shutdown after 60 seconds when UPS loses power. I have set this option in the energy saver settings under UPS, but the Mac Mini never shuts down. No matter what I set, it never shuts down or gives any indication of shutting down.
This M1 mac mini has had its data migrated from a Time Machine
backup of an Intel Mac Mini running OS X El Capitan 10.11.6.
The only thing that does work is a warning when the Mac Mini is drawing from the UPS.
Does anyone have any suggestions? Nothing in the previous threads have worked.
Here are the relevant settings:
pmset -g
System-wide power settings:
Currently in use:

pmset -g ups
UPS settings:

When UPS plugged in:
Now drawing from 'AC Power'
-Back-UPS ES 850G2 FW:931.a10.D USB FW:a10 (id=25296896) 74%; charging present: true
When UPS unplugged:
Now drawing from 'UPS Power'
-Back-UPS ES 850G2 FW:931.a10.D USB FW:a10 (id=25296896) 74%; discharging; 4:14 remaining present: true
This is so frustrating to have a machine that does not do what it is clearly set to do.
Does anyone have any suggestions? I can find zero information on anything that might be causing this.
