Taking control of the backlight on your Macbook Pro or Air keyboard isn’t hard: newer models specifically devote keys to the purpose. That wasn’t always true, however. Before the addition of keys for the job, there was basically no way to control the lights behind the keys manually. Newer Macs may allow you to manually turn the light level up and down, but the sensor still takes control when it feels like it. Lab Tick lets you turn this off, and does a bit more.
