The problem is that the version of RPG Maker I'm using doesn't support the latest Mac OS. I could port it to Mac, but it might not work properly on later versions of the OS. If there a way on Mac to play on legacy versions of the OS?
I believe there are ways to download and install old versions of OS. I know I personally never upgraded my Mac past Mojave specifically because I didn't want to lose the ability to play the first Fear & Hunger. I would personally love a port to Mac, but I can understand if that's not exactly a lucrative move given that most people wouldn't be able to play it without downloading an earlier version of OS.
