10.5.3 fixes MBA Ambient Light Sensor

May 28th, 2008

Since I bought my Macbook Air and moved everything on to it from my Time Machine backup, my ambient light sensor flat hasn’t worked. The screen would not dim or brighten, and the keyboard backlight would not turn on and off no matter what. I tried several recommended fixes from across the web without success.

Today must be a good day, though, because after installing 10.5.3, it works.
