I have the base spec mid 2011 iMac and have just upgraded to Mountain Lion. I have tried airplay mirroring to my appletv3 and I am not too impressed. I have both connected to my Airport Extreme by cable. Normal mirroring is ok but if I try and play back a video or anything the video and audio is jerky and out of sync. Is this normal or have I got some settings wrong? Am I expecting too much?
Cheers,
Richard
