Caps Lock button's green light not working after Mojave update I've updated to macOS Mojave from High Sierra recently. Since the update, the green light in Caps Lock button is no more working. 

The button is working, but the green light is not.

MacBook Pro, 15-inch, 2017 model.

Is there any solution how can I fix this issue?
I would suggest your reset your NVRAM, following the procedure from Apple.
