OK, the Apple support forums have long convoluted threads on this issue. So...what is the deal with a UPS and a MacPro. The issues I read about are: -overloading on wake from sleep. Will this damage my computer? If its just a power outage at the UPS and makes me restart my system I can live with that (once...then bring it back to the store to return the UPS) -sine wave vs non-true sine wave. Again...seems the non sine wave (simulated) work OK...but can damage the system? Right now its between the APC and Belkin 1500VA models. Any others I should consider?
