Try downloading and running the game from the itch app (https://itch.io/app)
It usually works great when my Macbook's being difficult.

Wow... that actually worked! Thank you so so much!
I thought it was an issue with RPGMaker and MacBook Pro 1.10.5+ compatibility... but it's great to see it working after fiddling with all sorts of permissions and trying to cd into the game folder and fiddle around with things! Thank you so much! I had no idea that this existed.
