Is there a YouTube Airplay button for MacBooks?
I can easily airplay YouTube videos through my Apple TV if I use my iPhone or iPad by simply going to the YouTube video and pressing the airplay button. Is there a similar functionality for MacBooks? My MacBook Air is updated to Mountain Lion and airplay works for mirroring and listening to stuff on iTunes, but there doesn't seem to be a button for YouTube videos. Is this possible at all? It'd weird if you could only airplay YouTube through iPads and iPhones, and not MacBooks.
MacBook Air (13-INCH, MID 2011), OS X Mountain Lion (10.8.2)
