I downloaded the newest file and it still will not open on Catalina even with all the tricks listed in other comments (Unarchiver, chmod +x). It only has a pop-up window saying that it can't be opened, nothing about the developer
Hey everyone. Sorry about this, I'm still figuring out this a bit. I created a new version, Catalina_v2, if anyone is willing to try it for me. (I don't have a Mac computer on hand atm)
