macOS DMG Builder

Overview

Use this skill to create a repeatable macOS release pipeline with signed and notarized .app and .dmg artifacts.

Prefer existing project scripts first. If the project does not already have release automation, scaffold it from assets/templates/ using the bundled script.

Onboarding Walkthrough (Mandatory)

Before running release commands, collect or confirm these values. Do not skip this step.

1. repo_root (absolute path to target repo)
2. app_name (display name of the app in Finder/DMG)
3. xcode_scheme (build/archive scheme)
4. bundle_id (for entitlement/signing sanity checks)
5. artifact_dir (where .app and .dmg should be written)
6. team_id (Apple Developer Team ID)
7. apple_id (Apple ID used for notarization)
8. notary_profile (Keychain profile name for notarytool)
9. signing_identity preference (display name or SHA-1 hash)
