I'm not sure what's going on with macs, but it seems that Apple likes to make trouble for other software. Also, on 10.15, they started to deprecating OpenGL to push their own rendering API. If I'll not receive any confirmation that the Mac version does work on some machines, I'll probably stop supporting this platform. There'll be a web version coming out next month, so maybe that will work.
But what's the problem? I used winrar this time, but now I'm reading that mac doesn't support that either... Does the file refuses to open or the game.exe? Any errors?
Since I don't own mac or afford to buy one, if you'd like to help, I could send you a file compressed in different methods or just an uncompressed file to try it out. Also, I read this
Though, I'm not sure what APP folder he's talking about.
I'll try asking around if there's a secret on how to make rpgm games work on mac.
Edit: Try this
Workupload This is a compressed version using default windows compressor.
If that does not work, try this
Workupload
If that doesn't work, maybe you need to do it from mac itself.
It would be really helpful if any of MAC users could confirm if this works or not.
