I recently purchased a Cyberpower CP1350AVRLCD UPS system for my iMac. Under Mac OS X 10.6.3, the UPS and the iMac don't seem to be communicating correctly. My Energy Saver preference pane doesn't show the battery charge level at all. Anyone else having issues with Snow Leopard and UPS systems? It seems to work correctly when I plug the USB cable from the UPS into a macbook running Leopard (10.5.8). Thanks!
