Mac user here, still cant get the game to run after following both guides. Any tips?
Get this popup every timeI'm afraid this version difference might be the case for your problem. I can't reproduce the problem on my virtual machine, but it's most likely tied to the operating system version. I run the recommended Mac OSX 10.10 while the official support says that MacOS Big Sur 11.0 and later are not supported at all.
It depends on a case-by-case basis since some players ran my games on unsupported MacOS versions. Kadokawa's (RPG Maker's devs) position is simple - you either run the tested version or it is provided as-is for anything different. RPG Maker uses support libraries for running on MacOS platforms and I guess there are problems with these on the newer platforms. Besides, they are gunning for a new RPG Maker MZ now and it's unlikely that MV (the platform that I use for my games) will get an update.
Sorry, looks like I can't help you here.
