Intel Mac handling of UPS

Problem with UPS

20” iMac, 2 GHz, Intel Core 2 Duo, 2GB RAM OS 10.5.6

I’ve just bought an MGE UPS, a model called NOVA 600 AVR (600VA, 360W).

Without trying it first, I installed the accompanying software from the CD.
After a re-boot the software daemon ran, but the control panel, called ‘UPS’ in the System Preferences, pops up when it’s clicked and says it doesn’t work with Intel Macs, so I can’t see any settings. (The full filename of the ‘UPS’ control panel is MGEUPSPowerControl. I’ve forgotten the daemon’s name.)

I know the daemon was running because I unplugged the USB cable and an error message appeared immediately warning me. When I re-inserted the cable, another message popped up telling me the connection had been re-made.

The web site (mgeops.com and called ‘Eaton’) has no updates. That’s okay, because they say in their literature that the inbuilt OS X routines will handle the UPS better, anyway.

I uninstalled all the Eaton software because the unit works as a UPS even though I had no communication with it.

Trouble is, the UPS doesn’t appear in the Energy Saver pane. I’ve followed Apple’s advice for ‘UPS units that don’t appear in Energy Saver’ (power off Mac, unplug UPS, switch it off for 2-3 minutes, switch it on again, power up) to no avail.

I have the USB connector cable running into a native port, not a hub.

Here’s a small, related thing. I always have my Energy Saver settings to never sleep and never sleep the display, but with the UPS connected, my screen has begun to dim gradually after a few minutes and sleep after 30 mins, overriding my selections. (The dimming and sleep occur only after inactivity, as they should.) Surprisingly, this occurs whether the USB cable to the UPS is plugged in or not, suggesting that OS X can see the UPS and is having some control imposed by it. The System Profiler sees it on the USB device tree as NOVA AVR with an appropriate vendor name (MGE Office Protection Systems by EATON Power Quality) and a few other specs. TechTool also sees it and passes it in the USB tests.

I’ve scoured web forums without success and would be surprised and delighted to find that you had an answer. Apple hasn’t.

Even a suggestion for a third-party utility that ran under Leopard and Intel chips. I’ve looked unsuccessfully for that, too.
