How to run this application

Are you being warned that Anniversary Edition Setup has not been signed by an identified developer when double-clicking it?  Due to this being a simple fan-produced application, the app is not signed with an Apple Developer certificate.  The macOS Gatekeeper security feature will refuse to run an unsigned app unless you right-click the app and choose "Open", then click the "Open" button in the "Are you sure?" prompt.

After doing this once, Gatekeeper will allow the application to run in the future.
