Download of LiteSwitch X 2.8.3 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this free Mac application is Proteron LLC. We recommend checking the downloaded files with any free antivirus.
From the developer:
LiteSwitch X follows the tradition of LiteSwitch as a simple solution for managing open applications using the keyboard. Like its predecessor which will continue to be available, LiteSwitch X has a clean, simple and functional style that has become Proteron's hallmark. It features an aquified transparent, resizeable window which is invoked by a configurable key-combination (default is Apple-Tab).
