I'll take a look when I get home.

 

Would be good if you could post your entire EFI folder too.

I use the following in my DSDT to add the PNLF device to /_SB:

            Device (PNLF)
            {
                Name (_HID, EisaId ("APP0002"))  // _HID: Hardware ID
                Name (_CID, "backlight")  // _CID: Compatible ID
                Name (_UID, 0x0A)  // _UID: Unique ID
                Name (_STA, 0x0B)  // _STA: Status
            }
        }

Then I use the GenericBrightness.kext in Clover/kexts/OSVersion:

 

GenericBrightness.kext.zip

 

Good luck.

Hi I'm not very good, can you add me what you said in my DSDT, please?

I added the PNLF device but I'm not sure whether this method works with Kabylake.  Try it out and let me know if it works.  First, look to see if you have a slider bar in System Preferences/Display.  Next, see if the slider bar works.

OK, I have the slider bar but it doesn't work.

Thank you for you help.

Thank you for you help.

 

Where did you put the GenericBrightness.kext?  If you are running 10.12.x, you should put the kext in Clover/kexts/10.12.  Then, rebuild kernelcache and reboot for it to work.  

 

If it doesn't, there are other brightness kexts beside that one.  You could try RehabMan's here:

ok i try this, but doesn't work

[mnfesq]

ok i try this, but doesn't work

 

From my research, people with Kabylake systems have reported success using the PNLF patch and RehabMan's IntelBacklight.kext.  Not sure why it's not working for you but I would try installing the kext in Library/Extensions and see if that helps.  Also, not sure what you are using to rebuild kernelcache.  Try using KCPM Utility Pro to install the kext in L/E. 

 

Lastly, you haven't posted what type of mobo your system has or any details about your installation.  Are you sure you have CE/QI functioning?

[B3TA01]

ok
