OSX 10.4.11 doesn't recognize APC Back-UPS BE550G, no UPS tab appears in Energy Saver panel, how can I get safe shut down at power outage?

Can't figure out how to solve this puzzle: the battery backup [APC Back-UPS BE550G] doesn't show up in the Energy Saver pane in a UPS tab nor beside the clock and Spotlight; will the (1 min. then shutdown) settings of the Saver be supported by the APC battery if there is a power outage or significant surge?


This new back-ups came in a box stating compatibility with OS 10.3.9 – 10.4.9. Am I out of luck with 10.4.11? Isn't the OS itself able to set prefs for an UPS?

Please help if you can. Thanks.

PowerMac, Mac OS X (10.4.11)
