So, I think the ALS works as it is supposed to in terms of turning up/down backlit keyboard depending on the amount of ambient light present. Where I have problem is that it takes A LOT of ambient light before the backlit keyboard turns off and locks, as in I have to be outside during the day or standing almost directly below a pretty bright light if I am indoors.


I have another macbook and it is a lot more sensitive and will turn off and lock backlit keyboard with a reasonable amount of ambient light. I have tested these two laptops side by side and the sensitivity/threshold is markedly different.


Can anyone help me with how I can go about adjusting the ALS threshold?
