Small problem, my energy preferences scheduled shut down time has never worked, ie it does not shut down my iMac 5.1 at the scheduled time. Any ideas how to get this feature to work??
Well, that's more than likely the problem. It's that .plist file that contains the schedule information. Try turning off your schedule information. Then re-open Energy Saver and reset them. Also use Disk Utility to repair permissions in case there is a problem in the Library folder.
