How To Turn Off Keyboard Backlight on MacBook Pro 2021?

Solution 1:

You can do it from the Control Centre — the new icon in the menu bar that looks like two sliders. When you click on that, it shows a dropdown with several small panes, one of which says ‘Keyboard Brightness’. Click on that, and it shows a slider that you can drag from full brightness all the way down to none.

Note that in System Preferences, the ‘Keyboard’ tab of the ‘Keyboard’ pane has a few options related to the keyboard backlight that you might want to check: in particular, the backlight can be turned off after anything from 5 seconds to 5 minutes of inactivity.
