Hello all, My 2011 Mac Mini has recently developed the habit of restarting itself every time you try to wake it from sleep. It only started doing this recently over the past few weeks, but nothing about the system has changed. It's really frustrating, and I'm not sure what the cause is. Short of a reinstall, is there any setting in the system where it causes a restart if there are certain criteria met, and if so, can we shut it back off? The Mac in question: Mac Mini 2011 i7 2.7Ghz (Sandy Bridge) AMD 6630M 750GB 7200 rpm HDD 16GB memory Any help would be greatly appreciated.
