Quote from the guide: "If you ever wanted to play around with a Mac OS but wanted to do it on your own hardware then this guide is for you. Dan takes you through the basic steps needed to create a "Hackintosh" in a simple to understand process. Grab that extra hardware off your shelf and put together your Mac today."
