Lost-Entrepreneur439 Posted May 25 Share Posted May 25 I have a Dell Latitude E6430 on Catalina, and the brightness keys should be Fn+Up arrow to make the screen brighter, and Fn+Down arrow to make the screen darker, however instead it's Fn+Insert to make the screen brighter, and Fn+F3 to make the screen darker. I also had the same issue when I was using Big Sur (I downgraded to Catalina due to poor performance in Big Sur). EFI is attached, specs in signature.
