I'm using my 2014 Mac Mini as a home server. I share the iTunes library and it hosts some VMs using VMware Fusion. It is fully update dated with Yosemite but I don't have OS X Server installed. Finally, I have a 2TB external drive connected that holds my music/movies. I have a few questions. 1. After a reboot, I have to physically connect a keyboard to the Mini to login for the first time. After that, I can use the screen sharing capability built into OS X to log into the system from my MacBook Pro without any issues. This seems a bit odd to me but is it supposed to work this way? 2. I've been having a lot of issues with the system just shutting down for no apparent reason, at least that I can tell. Recently it got stuck in a cycle where every time I tried to boot it up, it immediately went to the password recovery screen. I decided I was going to re-install everything to see if that fixed the shutting down/crashing so I decrypted the drive (i.e. turned FileVault off). After a few days, it seems to be doing better and staying powered on. Could FileVault have anything to do with this? Are there any known issues with using FileVault? 3. Could having FileVault on be the cause of issue #1? I haven't tried rebooting and logging in since I decrypted the drive.
