Q: Macbook Pro 13' Early 2015 doesn't have "Automatically illuminate keyboard in low light" option

Hi,

I am confused how the backlight keyboard works for new Macbooks with El Capitan OSX.

In a dark room the backlight cannot be turned on automatically ? In my case it doesn't work like that.

In my Macbook I don't see the option that is shown here Portables: Adjusting the keyboard backlight - Apple Support,

but I have "Adjust keyboard brightness in low light".
