A less common but still relevant option for people who choose to go another route when building their own PC and choosing their operating system may choose to configure what is called a Hackintosh system. This means that the user of the computer builds the computer specifically with the Mac OS in mind.

Following previously built systems that worked is very important for success in this area. This is not generally a recommended route, but this hasn't stopped curious enthusiasts from achieving success.
