mnfesq Posted July 25, 2017 Share Posted July 25, 2017 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. 2 Link to comment Share on other sites More sharing options...
B3TA01 Posted July 25, 2017 Author Share Posted July 25, 2017 Hi I'm not very good, can you add me what you said in my DSDT, please? Link to comment Share on other sites More sharing options...
mnfesq Posted July 25, 2017 Share Posted July 25, 2017 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. Hack2015-DSDT.aml.zip Link to comment Share on other sites More sharing options...
B3TA01 Posted July 26, 2017 Author Share Posted July 26, 2017 OK, I have the slider bar but it doesn't work. Thank you for you help. Link to comment Share on other sites More sharing options...

mnfesq Posted July 26, 2017 Share Posted July 26, 2017 OK, I have the slider bar but it doesn't work. 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: https://bitbucket.org/RehabMan/os-x-intel-backlight/downloads/ Link to comment Share on other sites More sharing options...
B3TA01 Posted July 26, 2017 Author Share Posted July 26, 2017 ok i try this, but doesn't work Link to comment Share on other sites More sharing options...
mnfesq Posted July 26, 2017 Share Posted July 26, 2017 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?
