Playtest or exported games don't work on Mac OS Catalina 10.15

[Narugami]

My question is short and simple. Is there a way to make RPG Maker MV games running on Mac OS Catalina again? Or will there be a patch resolving the issue?

The reason why the games or the playtest function on Mac OS Catalina doesn't work anymore, is because it is a 32bit application. And these are no longer supported on Mac OS 10.15. At least that is what I think.

Same thing happened on a dev Im following... According to him, moving into 64 bit and newer OSX stuff requires a whole lot of code remake/transition.. It also seems like upgrading the game code to work with 10.15 could make them unusable on older Macs. Its possible to do but for now all we can do is wait.

Also, on 10.15, Apple seem to start deprecating OpenGL to push their own rendering API...

Aside from the engine side of things though, it seems publishing your game to run on 10.15 requires the devs to do a whole lot more stuff now. So the work isnt just for Kadokawa/Degica but also on the devs themselves that would want to port on Mac.
