If you work in network support for Windows, sooner or later it's bound to happen. You'll be sitting quietly at your desk, and someone will walk up with a long list of questions about their Apple Macintosh computer. How do we connect it to the existing network? How will users access file shares, print, browse the Internet, and use e-mail? What do you do? You don't know anything about a Mac beyond plugging it into the wall.

Just remember that there is more than one way to peel an Apple!
