You can run Mac OS X on a AMD prosessor. ive ran Snow Leopard on a vmware machine. worked flawless. I cant remember the link on how to get it, sorry. just look up "get snow leopard on vmware amd". And it is possible...
one question, what prosessor is it? AMD Vision, AMD Phenom? either way, itl work with mac os x
if you have amd phenom, you can run up to mavericks. if you have amd vision(like me) only snow leopard and down
