Ah yeah that was fixed with patch 0.53.6, here's the latest patch 0.53.7 (which also contains that fix.)

Also, if anyone on Mac would like to give this a try, apparently there might be a way to get around the discontinued support for RPG Maker MV on newer Mac OS. If you could try this download and let me know if it works, that would be great, thanks. You will probably want to put the game in your Applications folder, and you might need to run chmod +x in a terminal on it to mark it as an executable.
