AppleTV and Clamshell Mode
I want to use Airplay with MBA 2011 Apple TV and Mountain Lion in clamshell mode, but when I close the lid after 15 seconds the display on the external monitor disconnects from AirPlay. MBA is not set to go to sleep. Can anyone help? Thanks.
MacBook Air (13-INCH, MID 2011), Mac OS X (10.7.4)
