macOS Human Interface Guidelines

Mac apps serve power users who expect deep keyboard control, persistent menu bars, resizable multi-window layouts, and tight system integration. These guidelines codify Apple's HIG into actionable rules with SwiftUI and AppKit examples.

1. Menu Bar (CRITICAL)

Every Mac app must have a menu bar. It is the primary discovery mechanism for commands. Users who cannot find a feature will look in the menu bar before anywhere else.

Rule 1.1 — Provide Standard Menus

Every app must include at minimum: App, File, Edit, View, Window, Help. Omit File only if the app is not document-based. Add app-specific menus between Edit and View or between View and Window.

// SwiftUI — Standard menu structure
@main
struct MyApp: App {
     body:   {
         {
            ()
        }
        .commands {
            
            (after: .newItem) {
                () { newFromTemplate() }
                    .keyboardShortcut(, modifiers: [.command, .shift])
            }
            () {
                () { zoomToFit() }
                    .keyboardShortcut(, modifiers: .command)
                ()
                () { addArtboard() }
                    .keyboardShortcut(, modifiers: [.command, .shift])
            }
        }
    }
}
