Using FaceTime
FaceTime is the latest communication technology from Apple that allows you to make video calls to anyone who has an iPhone 4 or newer, iPad 2 or newer, Mac, or iPod touch. FaceTime uses the built-in cameras on these devices to send a crystal-clear video of you to the person you’re calling, and you can see the other person talking back to you on your device.
FaceTime requirements
You need all of the following to use FaceTime for making video calls from your Mac:
An Internet connection using Ethernet or Wi-Fi.
A Mac running Mac OS X 10.6.6 or later (you have Mountain Lion, which is 10.8, so you’re okay).
A camera, of course, or there won’t be much video for your video call. You can use the built-in Mac camera, an external camera that connects to FireWire, or an external USB camera that supports DV/HDV cameras and the UVC specification.
A microphone, or the call will be a quiet one. Your Mac has a built-in microphone or you can use an external microphone connected to the audio port. USB and Bluetooth microphones/headsets also work.
An Apple ID to sign in to FaceTime.
