AirPlay issues on iMac (late-2012)
My devices:
iMac is (Late-2012 21-inch model) - OS X 10.10.1
3rd-gen. Apple TV (2012 model) - newest software.
When I using the Apple TV and try to AirPlay the movie from my iMac yesterday.
I find that my iMac can not AirPlay to my Apple TV.
Issues:
1. Apple TV just showing a black screen when I try to using Apple TV as the iMac 2nd-display.
2. Can not actived the AirPlay Mirroring on iMac. The AirPlay button is no response when I try to select the "Mirroring"
If I just AirPlay the music or movie from the iMac. It's fine!
Does any user meet the same issues?
p.s.
I have try to doing the same thing on my MacBook Pro. All functions are still fine,
Also my iMac and Apple TV have already reinstall the OS.
Thanks for your reading and hope you can help me.
