versions:
  macos: 27.2
  xcode: 27.2
user-invocable: false

<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 27.2 docs via Context7/Exa 3. **mcp__XcodeBuildMCP__build_macos** - Build for macOS validation

After implementation, run **fuse-ai-pilot:sniper** for validation.

Overview

When to Use

  • Building Mac desktop applications
  • Creating menu bar apps (MenuBarExtra)
  • Multi-window applications
  • Keyboard shortcuts and menus
  • Notarization for distribution
  • AppKit integration

Why macOS Skill

| Feature | Benefit | |---------|---------| | MenuBarExtra | Background utility apps | | Window management | Multi-window support | | Keyboard shortcuts | Power user productivity | | Notarization | Gatekeeper-safe distribution |

MCP Tools Available

Build Tools

  • `build_macos` - Build for macOS
  • `build_run_macos` - Build and launch
  • `test_macos` - Run macOS tests
  • `launch_mac_app` - Start built app

Best Practices

1. **Keyboard shortcuts** - Support power users 2. **Menu bar integration** - For utility apps 3. **Multiple windows** - Use WindowGroup/Window 4. **Settings window** - Use Settings scene 5. **Notarization** - Required for distribution 6. **Sandbox** - Enable for App Store

Questions about macos.

Which coding agents can use macos?
macos installs in Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode and Windsurf with the skills CLI, using each agent's flag shown on this page. Flowy's auto-invocation, which fires a skill when your prompt matches, runs in Claude Code only.
