To use the Crick USB Switch Box with our own software, no installation is necessary. Just plug it into your Mac, wait for it to be detected, and then launch Clicker / DocsPlus .

To use the Crick USB Switch Box with any other software, you need to install USB Keys 2. This converts your switch presses into keyboard key presses, letting you control any software controllable by keyboard.
