Which OSX do you want to install?
Did you test the machine with preinstalled OSX pendrive?

I'm sure links for clean ME 3437 BIOS are already posted on the forum.
You'll probably need to change serial numer.
Do you have Medusa programmer?
Upload your backup, if need to fix Fsys checksum too.

That file is reported as working BIOS, so try it first.
