Maybe this obvious, but after updating to 10.13.2 via the App Store I had to update the kext cache to get backlight control working again. A simple sudo touch /System/Library/Extensions and a reboot had everything working again.

Due to my previous fix the EV4 invocation was still out-commented, so the BRT6 method was not invoked (doh!). It is working now with: Method (BRT6, 2, NotSerialized) { If (LEqual (Arg0, One)) { Notify (LCD, 0x86)...

Thank you! Fixing the _OSI checks with SSDT-XOSI.aml fixes the issue. (On a side note: https://github.com/RehabMan/OS-X-USB-Inject-All/blob/09005e8255a1901741587292f565d15a71da44b8/SSDT-XOSI.dsl#L4 should read "Windows 2012") However what do you mean by: I have tested with ACPIDebug.kext: the...

I have updated my Latitude 3330 to High Sierra and almost everything is working correctly. It has working backlight control (using AppleBacklightInjector.kext). The problem is with the backlight control keys. Though they are working, the BIOS also responds to them. Upon a key press the BIOS set...

Indeed, Clover FixRegions caused SMIB to be set to 0x00. Thank you very much. Posted a bug report on the forum.

Sorry, maybe needed some rest first... Ok so I created the requested files: (notice there are some slight changes since last post as I have been working on the audio) After creating the file I noticed there is a difference between the disassembly (with iasl) of CLOVER/ACPI/patched/DSDT.aml...

While making progress on my Dell Latitude 3330 I have encountered an issue while making the battery status work. After reading the guide I found out I was very lucky as all my EC fields are 8 bit. However after installing ACPIBatteryManager.kext the battery status was not working. By debugging...

Not quite sure what you exactly mean by that however there seems to be only one DVMT prealloc in my IFR extract. Though I am getting a warning that I do not quite understand when accessing the variable: And setting 0x1C7 does not seem to be affecting the DVMT prealloc as far as I can tell...

I had very similar glitches on my HD 4000. See this thread for a possible solution: http://www.tonymacx86.com/el-capitan-laptop-support/181844-dell-latitude-3330-intel-hd-4000-glitches-noise-artifacts.html#post1173690

Not quite sure what you mean by that. So I created a Clover USB with legacy boot + MBR. Started my install with it, but the problem still persists. Any other suggestions on investigating/tackling this problem?

I do not understand. I have a working backlight control slider in system preferences. In the IOReq you can see AppleACPIPlatformExport/PCI0@0/AppleACPIPCI/IGPU@2/IntelBacklightHandler. What is not implemented? There is no other graphics card than the integrated Intel HD 4000. So can this be...
