I have a strange issue with my Late 2012 21" iMac, it has OS X Mountain Lion 10.8.2. The issue is this, if i turn on my iMac and then walk away for more than about 5 mins without logging in, it shuts down! it does not happen once I am logged in to OS X, I have never had this issue before with other Macs. Any ideas?

I am experiencing the same issue on a 17" MacBook Pro running 10.8.3 and a Mac Mini, also running 10.8.3.

Power on...
FileVault login...
wait... wait... wait... (don't have exact time)...
System auto-powers down...

I have to physically press the power button and restart then login if I wish the system to stay up.

Anyone else with this ever figure this out?

Thanks!

I'm a rolling stone.
I did not try this out but I think it's a smart way to do this, why waste energy if you don't login, if this is build into OS X Apple made a good choice to do so.
