Sign & noatarize MacOS binaries?

Perhaps we should sign & notarize the MacOS binaries for ease of use?

ChatGPT suggests that the steps are:

Without a Mac, you can still handle code signing and notarization using GitHub Actions. Here’s a step-by-step approach:

1. Apple Developer Account: Ensure that you have an Apple Developer account, as you'll need certificates and credentials for signing and notarization.

2. Create and Export Signing Certificate:

   • Use a Mac to create a Developer ID Application certificate, or obtain one from your team.
   • Export the certificate as a .p12 file.

3. Add Secrets to GitHub:

   • Encrypt your .p12 file and add it as a GitHub Actions secret, along with the certificate password and your Apple Developer account credentials.

4. Install and Configure xcnotary:

   • Use xcnotary, a third-party tool that supports notarizing applications via CI, which works well with GitHub Actions.
   • Install xcnotary in your GitHub Actions workflow by adding:

   • name: Install xcnotary run: brew install keith/formulae/xcnotary

5. Import Certificate:

   • Import the .p12 file in your CI workflow using:

   • name: Import Signing Certificate env: P12_PASSWORD: ${{ secrets.CERTIFICATE_PASSWORD }} run: | security create-keychain -p "" build.keychain security import certificate.p12 -k build.keychain -P "$P12_PASSWORD" -T /usr/bin/codesign

6. Sign the Universal Binary:

   • After combining the architectures using lipo, sign it with:

   • name: Code Sign run: | codesign --sign "Developer ID Application: Your Name (TeamID)" --timestamp --keychain build.keychain universal_binary

7. Notarize the Binary:

   • Use xcnotary to notarize your signed binary:

   • name: Notarize Binary run: | xcnotary notarize universal_binary --apple-id ${{ secrets.APPLE_ID }} --password ${{ secrets.APPLE_PASSWORD }} --team-id "YourTeamID"

8. Staple the Notarization:

   • After successful notarization, apply the notarization ticket to the binary:

   • name: Staple Notarization run: xcrun stapler staple universal_binary

Make sure your secrets are stored securely within GitHub Actions. This setup allows you to automate signing and notarization entirely through GitHub Actions without direct access to a Mac.
