I am not on my mac at the moment, but I believe airplay mirroring is accessed from the toolbar up at the top of your screen next to the time.
That's incorrect.
[h=2]AirPlay Mirroring[/h]Requires a second-generation Apple TV or later. Supports the following Mac models:
- iMac (Mid 2011 or newer)
- Mac mini (Mid 2011 or newer)
- MacBook Air (Mid 2011 or newer)
- MacBook Pro (Early 2011 or newer)
No it's not. All of those Macs have a 2nd (Sandy Bridge) or 3rd gen (Ivy Bridge) Intel Core i5 or i7 which features QuickSync in the CPU package. On a real Mac, the active graphics adapter doesn't have to be an Intel GPU to have QuickSync enabled.
In the Mountain Lion Developer Previews, it worked on lots of hardware, but as of the GM, it stopped.
That's incorrect.
