Today we will see the way that we can adjust keyboard brightness on MacBook Pro, MacBook Air, and 12-inch MacBook automatically. With this, what is achieved is an interesting energy saving and in principle the backlit keyboard sensor is the same one used for the computer screen, so when one goes down the other will also go down.
This is a very interesting setting for those who do not want to have the keyboard turned off and for those who do not need constant brightness to the maximum. Some users turn the keyboard brightness off and on from the settings found below the function keys, but the whole process can be carried out automatically and today we will see how it is activated.
Adjust brightness automatically
For the brightness of your keyboard to adjust automatically we simply have to access the System Preferences> Keyboard and directly select the tab that says: «Adjust keyboard brightness in low light conditions«.
In addition to checking this box we can schedule keyboard shutdown during idle time ranging from 5 seconds to 10, 30, 1 minute, or 5 minutes. Setting this off is also done by checking the option in the keyboard settings and they are really simple to carry out. With this, what we get is a lower energy consumption of the Mac, although it is true that each time this lighting is improved and now it has hardly any consumption.
