I've now uploaded the Mac version, although I'm led to believe it will run only on up-to-date MacOS v12 (which is called Monterey).

I recommend downloading the free trial version of CrossOver for Mac to run it most easily. The free trial download is fully functional and works for 14 days. I bought a license years ago to play Windows IF games like this. So buying was well worth it for me. But the free trial may be enough for you to play this game :) It is a great game.
