I recently delved into the world of Apple code signing and notarisation in order to automate the process in our CI build. My understanding is that you need to notarise on macOS Catalina or newer for binaries to run. Does this tool without notarisation solve a problem for you or are you still needing to do a notarisation step afterwards?
You still need to notarize certain apps, yes. This tool allows you to do everything up to notarization without macOS though. Closer to not requiring macOS. But not quite there.
Cool, a great step nonetheless.
