No, you are just experiencing the best of Apple. How dare you download non notarized binaries on your own computer? Do you have a license for that?

Terminal > sudo xattr -rd com.apple.quarantine > Drag and drop the app into terminal > enter and enter your password

Strange, I reckon I installed Tahoe just a while ago and still didn't have a similar issue, but I remember on previous MacOS versions the error message for unotarized binaries, was to warn that there was indeed a security issue with the binary, not that it was simply "damaged".

A bit crappy on Apple's side.

Thank you.

"damaged" by not paying 99 bucks.
