Dock (macOS)

The Dock is a central feature of the macOS operating system, serving as an application launcher and quick access point for frequently used files and folders. It is typically located at the bottom of the screen, though its position can be adjusted to the left or right edges.

The Dock dynamically displays icons representing running applications, allowing users to easily switch between them. A small indicator, typically a dot or line, appears beneath the icon of a running application. Applications that are not currently running but are pinned to the Dock for easy access also display their icons.

Beyond applications, the Dock can also hold files and folders. These can be added by dragging them onto the Dock. Folders added to the Dock can be configured to display their contents as a stack, grid, or fan when clicked, allowing quick access to the items within. Files and folders are typically placed on the right-hand side of the Dock, separated from application icons by a vertical line.

The Dock's appearance and behavior can be customized via System Preferences. Users can adjust the size of the icons, enable magnification when the cursor hovers over them, choose an animation style for minimizing windows, and automatically hide or show the Dock as needed. The Dock's presence is integral to the macOS user interface, providing consistent and convenient access to essential resources.

The rightmost section of the Dock houses the Trash icon, used for deleting files. Items dragged to the Trash are not permanently deleted until the Trash is emptied. Downloads, by default, appear as a stack in the Dock after being downloaded from the internet.
