Hi! Sorry this took me so long, but I wanted to make sure that I had fully exhausted all options. Unfortunately, it looks like, for some reason, RPG Maker MV doesn't let PC users create Mac deployment copies of their games. Which sucks. So I'll need to find someone with a Mac and RPG Maker MV to make a deployment copy for me.
I'm really sorry! I hope I can find someone soon - or can afford to purchase a Mac myself to make a copy for it. When and if a Mac copy can be made, you'll be the first person I let know about it!
