Hi, not sure whether or not this belongs here or in the iMac section. Regardless, I have a new MacBook Air and I am trying to use my 2009 27" iMac as an external display. I have a MiniDisplay connector plugged into both. When I press Command-F2, my iMac's screen goes dark, and my MBA's screen goes blue.

MacBook Air (13-inch Mid 2013), OS X Mountain Lion (10.8.4), 8 GM Memory, 512 GB
