Do I need os mountain lion 10.8 or above to mirror via airplay/apple tv ?
I have an imac mid 2011 (core i5) and mac OSx lion 10.7.5 but the airplay icon does not appear in the menu bar.
I can get music to play via airplay and apple tv from itunes on this cumputer so it is not the apple tc component that is not working.
