Hey all,
I've noticed a strange issue with my late 2015 iMac 27" running High Sierra 10.13.5.
I have the auto adjust brightness toggle checked in system preferences Displays, and holding a light up, and then moving it away causes the display to change as expected. However, when examining System Profile Graphics / Displays it says No for Automatically Adjust brightness. I have tried a PRAM reset, and also toggling the setting off and back on, but the value in System profiler doesn't change. The same value is listed on a late 2013 MBP as N, when it's enabled. What's going on here, and is there something I need to do to make it say yes? Or, am I reading it wrong.
Thanks,
