Brightness adjustment doesn't work since I updated my MBP 2017
Hey There,
After I updated my MacOs to Big Sure It stopped functioning it shows me in the touch bar that it going up and down but nothing happening on the screen itself.
I tried reinstalling Catalina and it worked. but once I update it to the latest version which is Big Sur 10.6 it stops working.
Please I searched everywhere for the solution but none helped me.
MacBook Pro 13″, macOS 10.15
