Mac OS X Tiger

Dashboard was a part of Mac OS X introduced in 2007 (version 10.4, Tiger). Dashboard served as a secondary Desktop that allowed access to a user-customized set of widgets, such as weather, calculator, notepad, stocks, and others. The Dashboard feature was discontinued after the release of macOS Mojave (version 10.14). However, widgets continue to be a part of macOS.
