troorl Posted January 4, 2019 Share Posted January 4, 2019 Hi. I've been having this problem for a while with different versions of macOS (currently on Mojave). When I set brightness on my display to the lowest level using Fn+F3, it's still too bright for a dark room. I still can use the standard functional key (down arrow) to make it dimmer, but it's resets each time after sleep or turning off the display, it's very annoying. Perhaps, there is a workaround for this issue?Insert other media Link to comment Share on other sites More sharing options...
troorl Posted January 4, 2019 Author Share Posted January 4, 2019 As it often happens, I found the solution through search. Basically, it's AppleBacklightInjector.kext plus SSDT-PNLF.aml. I just folled the instructions in the readme file. Thanks to everyone who contributed to that fix, it works perfectly for me.
