Im in the market for a UPS. I want it to protect my mac mini and external drives in a power outage, mainly for the feature of being able to turn properly shut my mac. The only thing preventing me from pulling the trigger is the fact that OS X Lion has issues shutting down when certain apps are running and if I'm not present to shut them, the system would be abruptly shutdown when the battery dies. Has anyone found a workaround to this issue?
