I find Apple's statement https://developer.apple.com/news/?id=12232019a confusing:
"In June, we announced that all Mac software distributed outside the Mac App Store must be notarized by Apple in order to run by default on macOS Catalina".
1. What does "run by default" mean? Does this mean that the User can still option-click and Open or that they can use the System Preferences->Security & Privacy to run the app... or will those methods also fail after that date?
2. If a Catalina User has been running my unNotarized software will it stop running on Feb 3?
