Well, you can use Executor from
ardi, which does not require the Mac rom, but the interface is not quite the same as Mac OS. Of course, if you really want to learn about the Mac, the ideal solution would be to use the real thing. Roms are not that hard to find, though; so far I have a Mac rom, kickstart roms 1.1 and 3.1, an Archimedes rom and an Atari TOS rom. I can send it to you, if you like.
