Is it because of the new version, or did the old version work fine?
Anyway I also added this readme to the download, maybe try some of this:
FOR MAC OS downloaders: I packed it as a .RAR file! On Macs some unzippers can corrupt the files, We've tested unpacking with "StuffIt" and it worked. If you need a different one, try: https://apps.apple.com/us/app/the-unarchiver/id425424353?mt=12 This one should be official but we haven't tried it!
If you still get an error (this application cannot be opened), try this: https://stackoverflow.com/questions/50577473/unity-game-compiled-in-windows-doesn-t-open-in-mac
