I just installed an apple TV (1st genertaion) and it doesn't mirror whay I see on my MacBook Air......isn't it capable to do so??....I saw that capability on the apple TV (3rd generation)
Try going to Settings on your Apple TV then click General>Then Scroll down to Software Update. Im not sure if certain Apple TV's were excluded from the new update but give that a shot.
Actually Im sorry but the first generation ATV doesn't support the newest update. Shucks!
