Set up direct (outside the Mac App Store) distribution for a macOS Xcode app: a dedicated "Direct" target — sandbox off, hardened runtime on, a DIRECT flag, direct-only frameworks linked to it alone — wired to Sparkle auto-updates with EdDSA signing keys, a SUFeedURL, a "Check for Updates" menu item and an appcast signing script — and, for selling that build, a licence key from a hosted checkout, kept out of the App Store build. Use whenever the user wants automatic updates for a Mac app sold…
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
# Direct distribution + auto-updates for a macOS app Give a macOS app a second distribution channel — a notarized DMG downloaded from your own site — that lives **alongside** the App Store build from one codebase, and updates itself via Sparkle. This skill creates the build target and the update mechanism; the **notarize-and-distribute** skill builds the signed DMG. The hard part is keeping the two channels cleanly separated. The key constraint: **a linked framework is embedded per-target, not per-configuration**, so keeping Sparkle out of the App Store build (required by Guideline 2.4.5) means the direct build needs its own *target*, not just a build config. See [references/xcode-target.md](references/xcode-target.md) for the full rationale. ## Prerequisites - **Tools:** Xcode 16, and the `xcodeproj` Ruby gem (`gem install xcodeproj`, or via the project's `bundle`) — the scripts use it to edit the project safely. Sparkle itself is added as a package dependency, not installed. - **Credentials:** a Developer ID Application certificate, plus the Sparkle EdDSA key pair this skill generates and stores in the keychain. Notarization credentials belong …

How to install
mdr add yybd/app-factory/macos-direct-distribution@sha256:861dd942a3427600The line at the top of this page pins the label git:20261021.202b5c1, 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.
