jwresp Posted March 30, 2017 Share Posted March 30, 2017 After I upgraded to Sierra 10.12.4 yesterday, brightness is not working anymore. Instead the brighness is at the maximum value. Changing the brightness with Fn+F3 and Fn+Insert shows apple's brightness indicator changing, however without effect. I tried installing Rehabman's latest IntelBacklight.kext on my EFI partition, without luck unfortunately. What are the steps I should take in order to fix the brightness in Sierra 10.12.4? Thanks!

Administrators Hervé Posted March 30, 2017 Administrators Share Posted March 30, 2017 Afaik, there should be no need for IntelBacklight kext on your Azul (HD4400) E7440. My Azul (HD4600) E6440 runs 10.12.4 as per any previous OS X version with "just": Azul framebuffer/layout-id 0x0a260006 injection in DSDT Desktop HD4600 id injection in DSDT Rehabman's FakePCIID + FakePCIID_Intel_HD_Graphics kexts After upgrading to 10.12.4 from 10.12.3, I still have the brightness bar in the display PrefPane and I can still increase or decrease brightness with Fn-Insert or Fn-F3.

jwresp Posted March 30, 2017 Author Share Posted March 30, 2017 Thank you for your reply Hervé, I have used the E7440 bootpack from the Clover Guide with a replaced VoodooPS2Controller from Dr Hurt. In my EFI kexts there are two files listed similar to the ones you mentioned: FakePCIID.kext and FakePCII_HD4600_HD4400.kext. Are you suggesting to replace them by FakePCIID + FakePCIID_Intel_HD_Graphics kext's from the latest release of RehabMan's OS-X-Fake-PCI-ID?And can I then safely remove IntelBacklight.kext? I am relatively new to patching, therefore I am not sure if my DSDT from the bootpack contains the patches you mentioned. Can I find this out by unpacking my DSDT using MaciASL?Thank you for all your help. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 30, 2017 Moderators Share Posted March 30, 2017 Go ahead and update those kexts and remove IntelBacklight. If it's still not working, you could try my new E7440 files here under Sierra. 1 Link to comment Share on other sites More sharing options...
Administrators Hervé Posted March 30, 2017 Administrators Share Posted March 30, 2017 Your Azul/HD4400 tuning should be visible either in your Clover configuration file (config.plist) and/or the iGPU section of your DSDT (look up for the _DSM method that should be under the iGPU or GFX device located at address 00020000). Regarding the Clover config file, I recommend you open it with Clover Configuration app. Regarding the DSDT, indeed you can open it with MaciASL. If in doubt, post a zipped copy of your EFI folder and we can have a look. Link to comment Share on other sites More sharing options...
jwresp Posted March 31, 2017 Author Share Posted March 31, 2017 Thank you for your replies. When I looked through my config.plist, I found out that there already is a FakeID IntelGFX 0x04128086. I also found multiple AppleIntelFramebufferAzul patches which probably should be removed. I have included the full EFI folder if you would like to have a look. Can you tell me what should be removed? In Jake Lo's Kexts/Other/LE folder I found a AppleBacklightInjector.kext which probably also should be included. Would it be possible to check the EFI folder of Jake Lo from a usb stick or secondary hard drive, without removing my current EFI files? Thank you for your time. Edit I tried Jake Lo's EFI folder, and everything works perfectly. Thank you so much! Except for some reason the alt + windows key have switched. (Switched by replacing the alt and windows key on the keyboard ) and the tilde sign cannot be entered with the leftmost key. Instead a § is entered.

Moderators Jake Lo Posted March 31, 2017 Moderators Share Posted March 31, 2017 What keyboard did you select? Use ANSI and the alt+command key should be correct and the ~ key should also work. By the way, you signature is wrong, should be E7440, not E4400. 1 Link to comment Share on other sites More sharing options...
jwresp Posted March 31, 2017 Author Share Posted March 31, 2017 Thank you, setting it to ANSI fixed the issue with ~. The alt and windows key are still switched, however I like it this way as on MacBooks the command key is also next to the spacebar. Link to comment Share on other sites More sharing options...
Schiller Posted April 19, 2017 Share Posted April 19, 2017 I have the same issue with brightness and keys not working after upgrading to 10.12.4. I just installed brightness by berg design http://bergdesign.com/brightness/ as a workaround, I miss the Fn+F3 and Fn+Insert though. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 19, 2017 Moderators Share Posted April 19, 2017 Replace with new Sierra bootpack. Remove IntelBacklight.kext from /EFI/Clover/Kexts/Other Link to comment Share on other sites More sharing options...
