Hopefully someone can help with this. Here's my hardware...
2011 Mac mini running macOS High Sierra
LED Cinema Display 24" (I think!)
Apple Keyboard (2003 version, I think!)
There've beens some times when the brightness controls aren't working. When I press F14 and F15, the box pops up on the screen but the bar doesn't move and the brightness doesn't change. To get it to work, I have to shut down and restart the mini.
I currently have f.lux and Amphetamine installed, but I had them before this started happening.
