Apple's Mac OS X can legally only be used on Apple's Macintosh range of personal computers.
Technically OS X can run on a PC, and many hackers have created "cracked" versions of OS X that will run on a PC. The reason it does not is because Apple requires OS X to be run on "Apple Branded Hardware".
Os X is the operating drive on which a Mac and any apple device functions on. When there is an Os X on a PC it means that it is compatible with devices from apple.
To install Apple's Mac OS X you agree to only use it on hardware built by Apple and so it is illegal to use it on other platforms.
You'll have to get a specific version available on the Mac OS X platform, unless the CD that came with the CD says it also works on OS X (such as Spore).
I can't understand your question.
To comply with the legal agreement you agree to when installing Mac OS X the PC needs to have been made by Apple.

Games labelled PC will require the Windows operating system. The MacBook uses the Mac OS X operating system and so games designed for PC/Windows computers will not work on a Mac. You will either need to purchase a version of the game designed for Mac OS X or install the Windows operating system on your MacBook and then use the PC/Windows game.
