Hi, I originally got the new (mid 2010) Mac Mini, but after reading into the features of Snow Leopard Server, I decided to exchange it for the (mid 2010) Mac Mini Server. It runs great, I'm really happy with it, but the one issue I have is it won't enter sleep mode on it's own. I've went into all of the System Preferences settings and changed everything to allow it to sleep (SL Server by default does not set it to sleep). However, when the set time is reached, it never enters sleep mode. If I go to the apple icon --> Sleep, it will enter sleep mode fine. I have tried resetting the PRAM and SMC, but that did not change anything. I've read one posting on Apple's support forums where someone said they reinstalled the OS and that worked (on a 2009 mini). Any other ideas before I have to do a reinstall?
