A playtester for no signal tried running the game on MacOS, but found that they couldn’t. Instead, MacOS displayed this error (edited to remove the timestamp):

“no signal” is damaged and can’t be opened. You should move it to the Trash. Firefox downloaded this file today at XX:XX.

I’m aware that Apple likes to do this kind of thing for unsigned applications downloaded from the internet, which is the case for no signal. The usual workaround is to right click on the application and click open, but this doesn’t work for them.

Eventually, they found out the following workaround based on this Reddit comment.

xattr -dr com.apple.quarantine "no signal.app"
