> Getting macOS code signing and notarization working in CI was honestly the hardest part of this project. If anyone is distributing a macOS app outside the App Store via GitHub Actions, I'm happy to answer questions — the workflow is fully open source.

If anyone wants to see another repo with this, we have it set up for Slippi (and various subprojects, like the Launcher): https://github.com/project-slippi/Ishiiruka

I'm thankful that it's largely a "once it's working, it rarely breaks". If it does break, it's usually because I have to sign in to the developer portal and accept some contract somewhere. Error messages in CI rarely indicate this is the case sadly.
