Thanks for solution with replacement kexts, I didn't know about that. I think Rehabman maybe can help with PCHL problem, but he's gone from forumHello,
Same problem here on Samsung NP530U3C. That damn fog. Thanks for your IntelBacklight.kext solution (change PCHLInit=-1 to 0 in plist). But i prefer ACPIBacklight.kext, it works without "fog" effect too , not so bright and more customizable. If you apply "[igpu] Brightness fix (HD3000/HD4000)" patch in MacIASL to your DSDT.aml and then change
Name(KPCH, Ones) Method (_INI, 0, NotSerialized)
- it will work, as it does same -1 to 0.Code:
Name(KPCH, Zero) Method (_INI, 0, NotSerialized)
But, of course, without controlling. I have no idea, how to make PCHL work with AppleBacklightFixup.kext and SSDT-PNLF.aml.
The only solution i found is to extract /S/L/Extensions/AppleBacklight.kext, /S/L/Extensions/AppleBacklightExpert.kext and /S/L/PrivateFrameworks/DisplayServices.framework from "macOS Sierra 10.12.3 Combo Update", and replace original Mojave 10.4.3 with them. Then control of ACPIBacklight.kext and IntelBacklight.kext returns and there is no fog. I know this is not what is this thread about, but... Better a small fish than an empty dish.
