Signing a desktop NWjs game for Mac App Store (MAS)

Has anyone done this?

The signing process is described here:

github.com/nwjs/nw.js/wiki/Mac-App-Store-%28MAS%29-Submission-Guideline

github.com/nwjs/nw.js/wiki/MAS%3A-Signing-the-app

But the links are pretty old, and the process requires a lot of manual work. I wonder if there a better/easier way to do this?

You have not tried to go the way of mobile publishing and already when packaging the archive to select MAC devices, this path is known and well-traveled.

I download and run my games on MAC but I have it on M processor and I am not sure that processors with intel can do it.

I'm not sure what you mean. I've done mobile publishing for Apple App Store, but that's a completely different process.

Yes, you can upload an unsigned game to Steam and it works on MacOS, but we hope that signing it will help to fix this permission issue.

Apple have official documentation on notarization here.
