Downloading DockEdit 2.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The program lies within System Tools, more precisely System Optimization. This free Mac application was originally created by Fredrik W. We recommend checking the downloaded files with any free antivirus.
From the developer:
Allows you to change the Leopard 3D Dock to a 2D Dock quickly and easily. According to Apple, Leopard contains over 300 changes and enhancements over its predecessor, Mac OS X Tiger,[2] covering core operating system components as well as included applications and developer tools.
