After upgrade to catalina 10.15.1, screen brightness is being reset to maximum after reboot, the behaviour is same even after waking up from sleep.
MacBook Pro 15", macOS 10.15
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'm having this problem too....really annoying having to keep recalibrating it!!!
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).
Mine is a Samsung. It never happened before Catalina.
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!
