macOS Notarization
Use this skill when you need to notarize a macOS app for distribution outside the App Store.
Preconditions
- Xcode installed and command line tools configured.
- Auth is configured (
asc auth loginorASC_*env vars). - A Developer ID Application certificate in the local keychain.
- The app's Xcode project builds for macOS.
Preflight: Verify Signing Identity
Before archiving, confirm a valid Developer ID Application identity exists:
security find-identity -v -p codesigning | grep "Developer ID Application"
If no identity is found, create one at https://developer.apple.com/account/resources/certificates/add (the App Store Connect API does not support creating Developer ID certificates).
