FaceTime for Mac makes it possible to talk, smile, wave, and laugh with anyone on an iPhone 4, iPod touch, or Mac from your Mac over Wi-Fi. So you can catch up, hang out, joke around, and stay in touch with just a click. Sure, it’s great to hear a voice. But it’s even better to see the face that goes with it.
