Our application is a pure Intel application. So I guess the following applies to our application: "...macOS can run ad hoc signed (or unsigned, on Intel) code. If the code is quarantined then you need to bypass Gatekeeper, but there’s a documented process for doing that..." Not sure how to interpret "...or unsigned, on Intel..." does that mean that a pure unsigned Intel application should be able to run on both Intel and Apple Sillicon Macs ? Or does it mean that it's only on Intel based Macs that a pure unsigned Intel application can be launched ? All of the above of course using the "...documented process..." for launching the application.

It is a macOS application that we develop. It's based on the Eclipse RCP framework and is not signed.
