I tried building a macOS app with Electron, but I ran into problems during notarization.

I used notarytool to upload my DMG and got status: Invalid.

xcrun notarytool log output

I checked the signature of my .app file:

It looks like local signing succeeded, but notarization is failing. I’m a beginner with macOS signing/notarization. Could you please help me figure out what I’m doing wrong and how to fix this? I’d really appreciate any guidance.

Before we start, I want to be clear about the level of help I can provide here. DTS’s role here at Apple is to support the APIs in our platform SDKs, Apple tools, some developer-oriented Apple services (like notarisation), and accessory development. We don’t support third-party tools or libraries. I can assist you with the Apple aspects of this. If you need help translating that to a third-party setup, you should look for help via that third-party’s support channel.

Your code is not following the bundle structure rules in Placing content in a bundle. And that doc comes with this warning:

If you put content in the wrong location, you may encounter hard-to-debug code signing and distribution problems. These problems aren’t always immediately obvious.

In some cases you can get away with not following these rules. If you attempt to do that, you must sign your code correctly, per the process described in Creating distribution-signed code for macOS.

IMPORTANT THat means not using --deep when signing your code. See --deep Considered Harmful for more on that.

However, that doesn’t guarantee success. If you bend the bundle structure rules you might find that things work today but then failing in the future, or in some other environment.
