View Mac Screen on Apple TV
New in Mountain Lion is the ability to view your Mac’s desktop on Apple TV. That means anything you do on your Mac can be seen on a TV (plugged into an Apple TV).
Obviously, this is a major win for presentations in schools or at work. And watching anything you’re doing on the Mac up on a big ass TV. But there’s a catch – you need a newer Mac, purchased in 2011 or newer and of course an Apple TV… And it has to be a newer Apple TV too.
Sucky for me, my Mac is from 2010 so I’m screwed.
