Alright here is the situation: Shrike (my mac) has been running now for about 16 days straight (it has been put to sleep plenty of times though). I opened up my laptop and the OS just locked up. Nothing would work, not even the CMD + OPTION + ESC So I did the only thing I know to do in a situation like this. I did a hard reboot (Held down the power button until the machine shut down). Let it sit for awhile and turned it back on. It loaded up to the Apple Logo and is just sitting there with the status circle spinning. What happened? EDIT: OK, as soon as I hit submit, the OS X loading screen came up. But seriously what gives? Was it just doing a Scandisk or the like?
