I have a mid-2011 iMac (quad core i7) and every time I boot my iMac into High Sierra I always have to adjust my screen brightness. The "Automatically adjust brightness" setting is always checked and I have to uncheck it and change the level.
I reboot and go through the same process.
Anyone else have this issue?
Sidenote: This beta has been incredibly solid so far. I am very impressed. 🙂
