Brightness changing have a macbook pro 13 2014. Everything works fine on mac os mojave. When updating to mac os Catalina, changing the brightness of the screen does not work. The buttons themselves work, that is, you can see the brightness change icon on the screen, but the brightness does not change. I have been using brightness slider for a long time. Deciding to upgrade to mac os big sur, I was faced with the fact that when you click on the buttons, nothing happens at all, even the brightness change icon is not shown. And also when you exit sleep mode, the macbook itself works, but the screen does not. What can be in?

Same here. 1 month old iMac 27/i9 running 10.15.3 - and it only happens randomly.

Pretty jarring when working in a dark office!

Come on Apple!

I have dual monitors as well, with the same maximum brightness problem. It never happened before the Catalina update.

I do have a dual monitor setup, but it happens when I don't have any connected as well. The monitor brand is Acer (at home) and Dell (at work).

Hey, I just applied the 10.15.4 update this morning, and I think that this bug might be resolved. So far, so good. Hope I'm right!
