Among the many features that MacBook Pro comes packed is it’s keyboard back light. Normally, the keyboard back light only turns on when the MacBook Pro light sensor detects a dark room, but with Lab Tick now its possible to take full control it. You simply have to deal with the behaviour dictated by the ambient light sensor, which sometimes does not work really well. The idea of a backlit keyboard is awesome, but the implementation in Mac OS X has its flaws. Lab Tick aims to fix them.
