Somewhere between email and the telephone lies the joyous communication tool called instant messaging. Plenty of IM programs run on the Mac, but OS X comes with its very own instant messenger program called Messages. (It used to be called iChat.) It’s built right into the system and ready to connect to your friends on the iCloud, Yahoo, AIM, Jabber, Facebook, or Google Talk networks.
This chapter covers how to use Messages to communicate by video, audio, and text with your online pals.
