Use when shipping a macOS app outside the App Store — Developer ID signing with hardened runtime, notarization with notarytool, stapling, building a clean drag-to-Applications DMG, and verifying the result launches on a stranger's Mac.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# macOS App Distribution (DMG) Ship a macOS app outside the App Store so it opens first-try on a stranger's Mac: Developer ID signature, hardened runtime, notarization, staple, DMG. Miss a step and the user gets "*App* is damaged and can't be opened" — which most users read as *your app is broken*. ## When to use Use this skill when the user says: - distribute outside the App Store - DMG / disk image / drag to Applications - codesign / Developer ID - notarize / notarization / `notarytool` - staple / Gatekeeper - "app is damaged and can't be opened" - "cannot be opened because the developer cannot be verified" - hardened runtime Do not use this skill for Mac App Store submission (different signing + review pipeline), iOS distribution, or pkg-installer authoring beyond the note below. ## Core rule ``` Sign inside-out with Developer ID + hardened runtime, notarize the final artifact, staple both the app and the DMG, and verify on a machine that has never seen your certificates. ``` ## Prerequisites - Apple Developer Program membership. …

How to install
mdr add aka-kika/akakika-skills/macos-app-distribution-dmg@sha256:532b80dc0f7b424aThe line at the top of this page pins the label git:20260717.accdb14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
