It started life as a basic 2D Dock that was flat and slightly translucent and then morphed into a 3D look with Leopard. With OS X Yosemite, the Dock reverted to a 2D look. If you became fond of the 3D look and want to experience it in OS X Yosemite or later, or if you have an OS with the 3D look and want the 2D appearance, it's possible to switch between the two Dock looks.

OS X Cheetah introduced the Dock, creating the Mac desktop's distinctive look. It was a basic 2D dock with the original Aqua pinstripe interface elements introduced in the first OS X version. The Dock morphed a bit through Puma, Jaguar, Panther, and Tiger, but remained 2D.

With the advent of OS X Leopard, the Dock underwent a dramatic change with a three-dimensional, reflective look. The Dock icons looked like they were standing up on a ledge. The 3D look continued through Snow Leopard, Lion, Mountain Lion, and Mavericks.

For OS X El Capitan through macOS Big Sur, installing cDock requires an extra step that involves disabling your SIP (System Integrity Protection). This security measure prevents potentially malicious software from modifying protected resources on your Mac.

While cDock is by no means malicious, the SIP security system prevents cDock's Dock-modification methods. Disabling the SIP system isn't recommended just to perform cosmetic Dock changes. If you choose to go ahead with the process, cDock includes instructions for how to disable SIP.
