My iMac won't shut down on Yosemite DP5. I get the white spinning wheel on black Background for 20 minutes or so... Then I just shut it down by myself. Anyone else having this problem? It's a 2009 27" iMac.
I'm yet to confirm this but I use Remote Desktop a lot, at one point I thought Yosemite would not shut down properly whenever I used RDP, will test further.
