Amiga Novice!!
CrossMac or MaxDOS (both commercial programs under $100) for the Amiga will
read/write between Mac and Amiga formats and have options to handle
data/resource forks and such like. A free demo of CrossMac (should be on line
here) works but is crippled in one direction (only reads from Mac, I believe).
Someone else here mentioned the Mac<===>MS-DOS<===>Amiga alternative, which
works well as long as you understand the Mac's twin-fork issues.
You can also try Shapeshifter, a software Mac emulator for the Amiga (crippled
demo version) or a couple of commercial Mac emulators: Emplant and AMAX, each
of which seamlessly handle cross-format disk copying upon the Amiga platform.
Yet another option, if your two machines are close by, is to run a null modem
cable between them using terminal software on each machine. That bypasses the
disk issue altogether.
