Do you have an M1?

I'm already uploading a separate Mac build, but if you don't want to wait, here's another solution:

The reason the game doesn't run is the quarantine imposed by Gatekeeper. You can remove it in Terminal with the command
"xattr -d com.apple.quarantine" (without the quotes) and drag ShutUpandDance.app to the same line and then hit Enter. The game should start without problems after this. :)

UPD: Uploaded a separate Mac build to Google Drive. It's called "ShutUpAndDanceEp6RESpecial-1.0.-mac.zip".

Could you please try it within the Itch.io app? It works on my MacBook Pro. It should be fine if you play it within the Itch.io app

Or Drag the app to the application director and try again.
