Use when building Mac apps — menu bar extras, window management, AppKit integration, or notarized distribution outside the App Store.
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
<objective> Covers macOS-specific development: menu bar apps via MenuBarExtra, multi-window application management, keyboard shortcuts and menus, AppKit integration (NSViewRepresentable) inside SwiftUI, and notarization for distribution outside the Mac App Store. Lists the XcodeBuildMCP tools for macOS builds (build_macos, build_run_macos, test_macos, launch_mac_app, stop_mac_app) and references for app structure (MenuBarExtra, Settings, Windows), build tooling, AppKit bridging, and code-signing/notarization. Best practices: support keyboard shortcuts for power users, use MenuBarExtra for utility apps, use WindowGroup/Window for multi-window apps and Settings for the preferences scene, notarize before distributing outside the App Store, and enable sandboxing for App Store submissions. </objective> # macOS Platform macOS-specific development with window management and distribution tools. ## Agent Workflow (MANDATORY) Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`: 1. **fuse-ai-pilot:explore-codebase** - Analyze existing macOS patterns 2. **fuse-ai-pilot:research-expert** - Verify latest macOS 27 docs via Context7/Exa …

How to install
mdr add fusengine/agents/macos@sha256:fb4d2647d99c1698The line at the top of this page pins the label git:20260927.027656f, 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.
