Is there any command to control the intensity of keyboard light of a MacBook Pro?
I haven't found a great solution yet. Here is some information that can help:
Apparently there is a solution for Ubuntu on MacBooks.
Lab Tick runs on OS X but unfortunately not command-line (nor open source).
brightnessis free software to control the display brightness.
This turns off automatic backlight in low light:
defaults write com.apple.BezelServices kDim -bool false
This turns off keyboard illumination when computer is not used for 1 second:
defaults write com.apple.BezelServices kDimTime -int 1
But ideally I would just turn off the illumination under all circumstances. And I haven't found a CLI solution for that - yet.
This app can do it, using the (undocumented) CoreBrightness library built in to macOS. It works on my M2 MacBook Pro (2023 model). You can add custom themes or change the program to work to your liking. I modified it to run through the animation just once, not "forever" in a loop, and I set up simple "backlight on" and "backlight off" animations to call.
