I got my new mac pro 9 days ago and yesterday it crashed for the second time (which is 2 more times than my pc has crashed in the past year). I have not installed anything new on it yet (software, ram) that could be causing this. The crash or freeze is happening when I wake it, it will boot up to a frozen screen, I can see my dashboard, wallpaper, etc., but nothing works, mouse is frozen, etc. Could the patch cable attached to my APC battery backup play any role? Apple Care has me power down, unplug everything (monitor, APC, power cord), wait a minute and then power back up while holding command / Alt / R / P. They just sent me instructions on how to erase and install the operation system and if that does not work they say I will have to take it into a store and leave it. I don't want to erase yet, but this is really frustrating considering the investment (and that I believed the commercials that macs don't crash).
