Hello! That's strange. The only idea I have is that you are running in an incompatible operating system version. RPG Maker engine can be picky about this, and there's a strict list of supported OS versions for Mac, unlike Windows where pretty much everything goes.
As for the help, I'm afraid the only idea I can come up with is to maybe run the game via your browser. There's an entry in the Linux FAQ about this. It may not apply directly as-is to MacOS platform but should give you the general idea. Aside from this, there's an option to experiment with the nwjs version. But it's not recommended if you aren't sure what you are doing. Tinkering with it may cause side effects with other software you have installed.
