Asc Notarization

This handles the full macOS notarization pipeline: archiving with xcodebuild, exporting with Developer ID signing, zipping the bundle, and submitting to Apple's notary service using the asc CLI. It covers the annoying preflight checks like verifying your signing identity and fixing broken certificate trust settings that can silently break codesigning. The skill walks through each step with actual commands, including how to poll for results, fetch developer logs when things fail, and staple the notarization ticket for offline verification. If you're distributing a Mac app outside the App Store and need to get past Gatekeeper, this is the checklist.

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 login or ASC_* 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).

Inspect Trust Settings

If codesign or xcodebuild fails with "Invalid trust settings" or "errSecInternalComponent", the certificate may have custom trust overrides that break the chain:

# Check for custom trust settings
security dump-trust-settings 2>&1 | grep -A1 "Developer ID"
