(didn't know where to post this, hope this is right?)

I'm running a HP G60 with AMD Athlon Dual-Core QL-60 2 .
I'm currently using Ubuntu 12.04 but want to try and install mac os. Is there a compatible version for my laptop where things that I need (such as wifi) will be working?
And if so, can someone lead me onto the path of a tutorial to install, as with all these different versions I am getting confused which to follow.
thanks in advance,
Matt
