emulating "mac os" on pc

i heard that it is possible to emulat mac os on pc but. i have no idea of woh it can be done and what version of mac os.
For emulating "mac os" on pc try this:

• As of now, "emulating mac os on pc" is possible but the result is unusable. (because apple has not released a retail version of mac for pc, the version they sell will only run on intel hardware sold be apple ) ... ... first you have to get a developer image for Mac OS, then patch it according to your needs. Even after that you will be able to see the hdd as ~6GB....
