Brightness control no longer working after Big Sur """upgrade"""
I've decided to update my MacBook Air (11-inch, early 2014) to the new iOS Big Sur.
Suddenly, I've realised that I no longer can control the brightness of my display.
I now read in the macOS User Guide that: "You can’t adjust the brightness of some older Apple displays." What do I do now????
Buy some sunglasses to work on my MacAir???
PS - Please don't tell me that the only solution you have is for me to downgrade back to Catalina.
