# macOS Platform

macOS-specific development with window management and distribution tools.

## Agent Workflow (MANDATORY)

Before ANY implementation, launch in parallel:

1. **fuse-ai-pilot:explore-codebase** - Analyze existing macOS patterns
2. **fuse-ai-pilot:research-expert** - Verify latest macOS 26 docs via Context7/Exa
3. **mcp__XcodeBuildMCP__build_macos** - Build for macOS validation

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

## 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
