Airplay icon disappears after mac wakes up from sleep I have found that when my mac wakes up from sleep, sometimes there is no airplay icon. The  only way I can fix this is by doing a recycle of my MacBook Air. I was wondering if there was any other way to have the airplay icon back on my MBA without having to restart it. Perhaps there is a command I can type on the Terminal. Anyone has a clue?

(FYI - Restarting the AppleTV does not solve the issue so I believe its a Mountain Lion part of things.)
Try cycling your MBA's Wi-Fi? I would expect powering your machine's antenna down and then back up would re-engage the Airplay internals.
