Feedback Unity should have full built-in support for Notarizing, Signing, and the Mac App Store.

There should be full built-in support for notarizing, signing, and preparing builds for distributing via Mac App Store and outside of the Mac App Store.

When I enable "Use Mac App Store Validation" and make a build, Unity should generate a package for me that is ready to be uploaded to App Store Connect without ANY fiddling with the CLI.

These are fundamental requirements that every single Unity developer who is targeting macOS needs.

 

Mac App Store Validation

isn't meant for any of this. As per Manual:

(https://docs.unity3d.com/Manual/HOWTO-PortToAppleMacStore.html)

Notarizing and signing are things that have to be done via Apple's Xcode environment:
