Hello,

I followed up a guide from the first post and I cannot get it to work.

I noticed that AppleBacklightInjector.kext is not displaying on the list when I ran "
sudo touch /System/Library/Extensions && sudo kextcache -u /" but I definitely installed it.

Please see my files for problem reporting attached.

Thanks again for your help !
