Hmm, let's see. What kind of MacBook Air do you have? A modern one or an older one? macOS doesn't support 32 bit apps anymore, which is why I'm guessing it won't run out of the box. We might need an emulator of some sort, or virtual machine running an old version of macOS.

If you were to download that, then the Macintosh System 7 or 8 binary files, you should be able to run your game that way. You may want to check Macintosh Garden to download the game to your computer via an .iso file instead of running it off the disk. Not sure if it would work that way.
