macOS app UI guidance distilled from historical Apple Human Interface Guidelines and Mac-assed design analysis. Use when designing, auditing, reviewing, or updating SwiftUI, AppKit, Catalyst, or other desktop Mac app interfaces to feel like a proper Mac app: menus, windows, panels, dialogs, controls, labels, keyboard shortcuts, icons, preferences, help, drag and drop, feedback, platform conventions, expressive identity, and tasteful custom UI. Ignore iOS-only advice.
