Hello, wigglecoin!
Unfortunately, I don't have a mac so that limits my ability to walk you through - but can I see screen caps of what you're looking at?
I tried to get help from a friend who is a mac user but she sees only a readme file and the game application when she goes into the folder - and it sounds like you are experiencing something different.
I worry it might be a version issue - the friend has Mojave and I feel that if you're on Catalina, it is unlikely to be able to run the file (Unfortunately, Catalina has caused a lot of issues for a lot of small game devs being able to make their applications available to mac users)
