The Dock is a desktop application designed to reduce desktop clutter, provide users with feedback about an application, and allow users to switch easily between tasks. With OS X version 10.1 and later, you can customize your application Dock tile by modifying the Dock icon and adding items to the menu displayed for your application. With OS X version 10.5 and later, Cocoa applications can customize the Dock icon of a minimized window.
This document provides an overview of the Dock and describes how you can customize the menu associated with your application Dock tile. It does not describe how to create icons. You should consult OS X Human Interface Guidelines for tips on designing Dock icons, naming Dock menu items, and using badges in your Dock tile.
