EDIT: This guide is very outdated and it doesn't exactly go into specifics all that well. By now there are much easier and less time-consuming ways to install Mac OS X on a PC. It will be kept up here for archiving purposes.
Hello. Today I will show you how to install Tiger, Leopard, or Snow Leopard on your PC running Windows. This will also tell you how to dual boot Vista/7 and OS X.
IF YOU INSTALL OS X (OR ANY MACINTOSH OS) ON A PC OR ANYTHING THAT IS NOT APPLE BRANDED, YOU ARE BREAKING YOUR END USER LICENSE AGREEMENT WITH APPLE! ALSO, YOU RISK MESSING UP YOUR COMPUTER IF YOU DON'T KNOW WHAT YOU'RE DOING! I AM NOT, AND WILL NOT BE HELD RESPONSIBLE FOR WHAT YOU DO WITH THIS KNOWLEDGE! IF YOU'RE NOT A COMPUTER GEEK, I SUGGEST YOU STAY AWAY FROM THIS INSTRUCTABLE, AS IT INCLUDES A LOT OF TECHNICAL STUFF! AS SAID ALREADY, I WILL NOT BE HELD RESPONSIBLE FOR ANYTHING YOU CHOOSE TO DO WITH THE KNOWLEDGE I AM PROVIDING YOU!
Also, when you install Mac OS X on a PC, the PC will officially be known as a Hackintosh PC (or Hac for short).
And of course, be sure to back up your data before you start, just in case something goes wrong.
With that out of the way, let's get started!
Step 1: WHY WOULD I WANT TO INSTALL OS X ON MY PC?
Q: Why install Mac OS X on my PC if I can just go out and buy a real Mac while avoiding legal issues?
A: It's so much cheaper. In addition, Hackintosh allows you to build a PC out of your own parts (assuming they're compatible) without needing to worry about Apple's low-end specs.
Q: What's the difference between a legit Macintosh and a Hackintosh PC?
A: There are a couple, actually. First of all, as I mentioned in the last question, a Hackintosh PC would be much cheaper. Secondly, if you have a really high end PC, it can probably run Mac OS X better than on a Mac because, Macintosh computers aren't fast for their hardware configuration, but their operating system. Apple has made OS X so lightweight (except in terms of hard drive space it takes up) that they don't even have to make high end computers. And yet they sell like crazy. And lastly, YOU get to choose what version of OS X you want (Tiger, Leopard, or Snow Leopard). They can't put you on the latest version.
Q: Why would I want Tiger or Leopard when I could just install Snow Leopard, the latest version?
A: Snow Leopard, like all other OSes, has system requirements, unfortunately. Your PC might not be able to handle the intense awesomeness of Snow Leopard.
