Silicon M1 Max (64G x 1TB) running Sequoia 15.4.1, connected to APC SMT1500 via USB-A to USB-C cable to one of the Thunderbolt ports on the back of the M1. I have also tried an APC USB-A to Ethernet (serial) cable plugged into the appropriate ports.
I have tried multiple cables, restarted both the Mac and the UPS, ensured the UPS USB port is active via its settings and still get no UPS options in Energy.
APC documents say there is no Mac version of their control software and direct me to the Apple Support document listed above.
Any clues or tips as to how to move forward would be most appreciated.
I have an APC UPS connected to my MPB M1 Pro on macOS 15.4.1. I’m not sure what sort of options you’re looking for, but all the information I get on the status of the UPS is in the Battery icon in the menubar. When I’m connected to the UPS, the icon changes form (slightly), and clicking on it gives me some brief status details on the unit. The only other reference I’ve seen is in the Battery control panel, where a “UPS level” percentage is added to the right of the normal battery status message at the very top of the panel.
Strange. I’ve got an APC SMT-1500C connected to my M4 mini via a USB cable from the UPS to a hub to the Mac. When I go to the Energy panel, there’s a UPS button:
If you don’t find it there, then check the USB connections. Make sure you are using the right kind of cable. APC seems to use a non-standard USB connection, requiring a proprietary cable that has a type-A connector on both ends. If you use any cable other than the one that comes with the unit, it will probably not work.
