There are many great tutorials on the web for using a Mac to install Mac OS X Snow Leopard on a PC. Unfortunately, you may be unable to follow such tutorials if you do not readily have access to a Mac to perform the preparation necessary for the installation.
Great progress has been made in hacking PCs to run OS X, and it is now possible to install Mac OS X without a Mac. Thanks to some great tools put together by some brilliant hackers, it is also much easier and does not involve nearly as much time and effort as was once required.
Step 1: Getting The Hardware Ready
I recently purchased the following set of hardware for the purposes of building a Hackintosh (often PCs running Mac OS X are referred to as such):
- Intel Core i3-530 Clarkdale 2.93GHz
- Gigabyte GA-H55M-USB3 Motherboard
- 4 GB DDR3 1333 RAM (2 x 2GB)
- DVD Burner
- MicroATX Computer Case
- 585 Watt Power Supply
- 4-pin to 8-pin Power Adapter
The motherboard has an 8-pin power connector on it, and although it is possible to connect a single 4-pin connector to it, you may encounter odd issues running with just a single 4-pin connector. To ensure that you provide sufficient power to the board, you should purchase the 4-pin to 8-pin power adapter. Alternatively, you could purchase a power supply with 3x 4-pin connectors (1 for the 20+4-pin main connector, and 2 for the 8-pin connection) or an 8-pin connector.
