...please stop saying OS X86.

That's the WINE port for OS X, which currently can't run any code on a PPC Mac, but should work as well as WINE for an Intel Mac. I've gotten JCS to run on Linux with WINE, I'm sure the same result could be achieved with Darwine.

However, to install Darwine requires some dabbling with the terminal, if you're not comfortable with a CLI, you should probably avoid it.

EDIT: Apparently, it has an installer. Go figure.
