Early 2011 macbook pro (identifier 8,3) with 2.2 Intel Core i7 processor connected over Wifi on 2.4 Ghz channel.
OSX 10.8 Mountain Lion
Apple TV 3 (fully up to date)
The stats I've read say airplay mirroring should work fine. I can connect both machines just fine. I can stream movies just fine. I can send music just fine. I just cannot mirror my desktop. I have the icons, a connection is made, but all that shows is a blank screen. I've adjusted the resolutions with no luck. I've shut down and rebooted both machines with no luck...
Any solutions or do I have to count my losses with Apple Airplay and spend more money on a 3rd party alternative (AirParrot)?
