Apple’s FaceTime video chat app for Mac OS X has left beta testing and is now available at the Mac App Store for US$0.99.
FaceTime was first introduced with the iPhone 4. FaceTime for Mac makes it possible to communicate with anyone on an iPhone 4, iPod touch, or Mac from your Mac. If you use one of the new MacBook Pros you get 720p clarity.
All you need is an Apple ID and an email address and you’re ready to roll. To start a video call with someone, find her entry in the contacts list. FaceTime works with Address Book so you don’t have to enter your contacts from scratch.
