I'm excited to share Afterglow, my After Dark module player for macOS. With Afterglow you can run the original After Dark modules on your Mac -- directly, not inside an emulated classic Mac OS. Even as your screen saver!
Afterglow is not a port or remake: it runs the modules on the Musashi 68k CPU emulator with a re-implemented Macintosh Toolbox and OS API layer to reproduce the original module behavior.
I hope you have as much fun running it as I did making it. Enjoy!
