Okay I think there is some confusion here...
History of Amiga Running Mac Software:
Original 68K Mac software ran thru an add-on called A-Max and Emplant.. While called emulators, they shared the SAME CPU as the original Mac (so it was just software that allowed the OS to run).
PowerMacs (using the PowerPC chip) could run on PowerPC based classic Amigas thru software called Fusion or iFusion.
That's thru MacOS version 9.x
OS X represented a change to a Unix style OS with the Mac interface on top of it. Only a couple of generations of previous Macs would run this OS, otherwise you had to buy new mac hardware..
AmigaOne's (which are PowerPC based) will run Mac OS X if the AmigaOne has Linux installed as one of it's OSes.. You run something called "Mac On Linux" to install and run OS X on it..
there is a faq on working with this at:
