Apple Vision Pro is now available in the U.S.

APC UPS works with intel iMac but not with silicon M3 iMac

My intel iMac works OK with APC UPS, but my new Silicon M3 iMac does not see APC UPS in System Settings Energy Saver.


I have tried a variety of USB cables including USB-C to USB-B, and the supplied APC USB-A to USB-C with several (working) adapters. Anybody got it to work? Maybe a firmware problem, or Apple not supporting it?


Thanks

iMac 24″, macOS 14.1
