I got the python app notarized and downloaded it fine. However, if you are caught by Gatekeeper and open the information window, you will see a lock and even if you enter the password to open the lock, it will not work. xattr -d com.apple.quarantine ./test.app You have to exclude it from the gatekeeper directly. I wonder if the downloaded app is unavoidable... or if there is another way.
