How do I set Monterey if power drops and the Mac Mini senses it has happened and is running off the APC Back UPS? All I can find is Energy Saver in System Preferences but no setting for UPS
Mac mini 2018 or later
You need a UPS with a USB cable that attaches to the Mac. Without that cable the UPS won't talk to the Mac. The battery in the UPS will drain and shut off and the Mac will shutdown abruptly and not safely. With the cable attached there are options on how to handle a power outage and when to safely shutdown before the UPS battery runs out.
