MacBook Pro 15 2018
The keyboard backlight stopped working after the last software update. The keyboard backlight comes up on the login screen but turns off after login credentials are entered.
Increasing the brightness automatically returns the setting to 0. Using the buttons on the touch bar does nothing.
Tried restarting the computer, then reinstalling Sonoma, still no backlight.
