Iam using windows 8.1 and want to install mac os on my system.
please help me a lot.
i m new to os .

If it isn't an Apple, then you probably won't be able to install Mac OSX on it directly. You should be able to install it in a VirtualBox virtual machine, assuming you have an install disc and license.

How about you buy a Mac? They're worth the money.

I read somewhere you can install osx on a pc but there were tonnes of command lines and other crazy stuff. Plus it is illegal. You could pick up a mac mini for a reasonable price and hook it up to a regular keyboard and monitor.

Doing this would get you in big trouble

It requires messing around with the CPU chip

There are plenty of hackintosh guides on internet. Buying and running OS X on its hardware is ten times more the fun.

Look up "hackintosh" or "customac" in your fave search engine and you will have a good project on your hands.
