Currently, Apple is unable to circumvent Gatekeeper without paying a membership fee of $ 99 per year. This seems unfair to me because it crowds out small developers (but this discussion is elsewhere).
For a rather cumbersome workaround, you can enable ReadMe or a note on your software download page to explain to users that they need to right-click your application, then click "Open" and then click "Confirm" to start it. I also found, experimenting that Gatekeeper does not run DMG file security checks or file installs , but only run / run applications. Therefore, in their DMG installer, you can specify some note in which the user is told exactly how to install and run the application.
Hopefully Apple will provide a workaround for developers (possibly a cheaper solution for limited membership) who are distributing free, open source software.
