Mac OS X 10.8 Mountain Lion Developer Preview 4

Mountain Lion, a.k.a. OS X 10.8, marries the Apple desktop operating system to iOS features that previously were found only on the iPhone and iPad. Among them: Messages, Notifications, Reminders, a Game Center, and better integration with iCloud. It's not a revolutionary upgrade to the desktop OS, but it should please Mac enterprise users.

AirPlay Mirroring

If you have a second- or third-generation Apple TV device, you can use your Mac to push content to an HDTV via AirPlay. Many people with iPads have been doing this for a while, and in Mountain Lion, Apple now lets you push 720p content from your Mac to your TV through Apple TV.

You can now view any Web-based, streaming video service that you have on your PC on your TV as well. As you can see from the screenshots below, it's easy to configure and set up. It's also easy to become addicted. This is one feature I missed when I switched back to my production box, which runs 10.7.4 Lion.

AirPlay lets you push your Mac's display through the Apple TV device to your HDTV. This is an easy way to get the content of your PC on your TV, provided you already own a second-generation or later Apple TV device.

You define AirPlay Mirroring settings in the Display Preference Pane. You can turn it on or off and choose whether you want options to be available from the menu bar.
