I doubt you'll get an AMD processor running MacOS you can check around YouTube and hackintosh forums tho.

It's possible, I've done it. There are very specific things you need to do, as I've detailed in this thread. the gist:
patch out CPUID check
write SSE4 handlers and use the exceptions to trigger your code
do the same for MMX
manipulate the TLB to use the proper addresses
