What problem does it solve? Distributing a macOS app outside the App Store requires Developer ID signing and Apple notarization, a multi-step process with cryptic failure modes like broken certificate trust settings and missing secure timestamps. This Skill walks through the entire pipeline from archive to stapled, notarized artifact. ## Core Features & Use Cases - End-to-End Notarization Pipeline: Archive with xcodebuild, export with Developer ID signing, ZIP the bundle, submit via the asc CLI, and staple the ticket. - Certificate Troubleshooting: Diagnose and fix invalid trust settings, verify the Developer ID certificate chain, and handle Developer ID Installer certificates for PKG files. - Failure Diagnosis: Fetch notarization status and developer logs to resolve issues like unsigned nested binaries or missing hardened runtime. - Use Case: You have a signed macOS app ready for direct download distribution. Use this Skill to export it with Developer ID, submit it to Apple's Notary API, wait for approval, and staple the ticket so it passes Gatekeeper offline. ## Quick Start Notarize my macOS app by archiving the Xcode scheme, exporting it with Developer ID signing, and submitting the ZIP to Apple with asc notarization.
