I know what you're gonna say, why should I want a server computer to go to sleep? Well, this is my home server, I use it primarily as a Time Machine destination, a Cache server for iOS and OS X updates and as an iTunes Home Sharing hub for our Apple TVs. However, the Mac mini running El Capitan 10.11.3 and Server 5.0.15 is not working 24/7, and I'd like it to go to sleep when no ones is home and not doing anything. Wake for network access works ok, if I manually sleep the Mac mini it wakes whenever someones requests a file, a movie on iTunes, starts a Time Machine backup, etc. The problem is that it does not automatically sleeps, even though I have the energy settings set to sleep after one hour. Server makes OS X bypass those settings and I can't seem to find a way to override this. Does anyone have a solution?
