I don't seem to be having much luck. I updated the Kext by basically changing the following to Followed by copy to /S/L/E and Repair/Rebuild then reboot. I still don't get the DP monitor show up when I do a 'detect displays'.

Hi Im having trouble getting dual external monitor output when docked. I have 1x DVI connected and 1x HDMI using a HDMI to DP adaptor. I cannot recognise the HDMI/DP monitor. DVI works ok. I am running Sierra using Clover as per Jake Lo's guide. First question is - should this work OOB based on the standard bootpack from the guide? Have tried booting with lid open/closed, sleeping then wake, only one monitor connected etc. but nothing seems to recognise the HDMI. Thanks Mike

Thanks Jake Lo!! The sound is working again now. The only one thing is that if I leave the volume at half level. When I reboot the slider appears to be at full level. However if I play some music it will play at half level volume, but when I press the volume key once the slider will jump up to max (as thats where the slider bar thinks it is I guess). Quite difficult to explain, and only a minor annoyance but good if there is a fix.

I found the screenshot for the KexttoPatch but it only shows for VoodooHDA, not AppleHDA ? Current screenshot of my existing KexttoPatch is attached

Ok thanks Can you help me some more with what I need to do for this :-

Thanks - just working through those now, could you confirm :- I need to update this part :- Return (Package (0x06) { "layout-id", Buffer (0x04)

Hi Jake Lo No, sorry I haven't actually given you the full story! It was okay following the upgrade, but I had an issue where the volume would be on maximum each time I booted up, and when I clicked a volume button it would reset to the correct volume, halfway or wherever the slider bar indicated. So what I realised was that, even though I have a build from your instructions, using Clover, my kext arrangements were different to what you had in your boot pack. So I went ahead and installed your bootlick kexts. (6 into EFI Kexts Others) and 3 into LE. Looking at the difference in my old Kext - I seemed to be using the VoodooHDA in the EFI Clover. I tried with the boot without caches, rebuild and then reboot, but still the same. Thanks Mike

Thanks. I did this, re-did permissions and rebooted. The cache output was The SIP is now However, still no audio. I should have mentioned it is a E6220. Anything else I can check?

Sorry to hijack the thread, but I have exactly this issue also. I do have SIP enabled, how do I disable this ?

Hi Herve Just to follow up, I managed to patch the native kext file with the Hex values in your post but unfortunately it hasn't altered the behaviour and I still can't boot with the LCD closed when docked. Steps were :- - Checked DSDT and patch already existed so didn't need to amend. - Obtained native AppleIntelSMBGraphicFB.kext from friend (as I hadn't backed up my original!). - Searched for hex values in EMlyDinEsH post and replaced all with values in your post. - Installed to SLE using Kext Wizard. - Ran commands to rebuild permissions/cache (this took a few attempts). Do you have any other suggestion on what I can check ? Or alternatively if anyone else happens to read this post and has a patched AppleIntelSNBGraphicsFB for ElCap E6220 .... Regards Mike

Ok thank you Herve, I will take a look into that.

Thanks, here's the output from that one: Last login: Thu Mar 24 13:17:11 on console Mikes-MacBook-Pro:~ Mike$ sudo touch -f /L*/E* Password: Mikes-MacBook-Pro:~ Mike$ sudo touch -f /S*/L*/E* Mikes-MacBook-Pro:~ Mike$ sudo kextcache -Boot -U / rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67061 0xFFFFFFFFFFFEFA0B for kext AppleIntelSNBGraphicsFB.kext File at path '/System/Library/PrelinkedKernels/prelinkedkernel' changed, cannot be used Child process /usr/sbin/kextcache[471] exited with status 77.

Thanks for your help Herve. Unfortunately I still haven't got it working. It's probably me not understanding the technicalities/process fully. I am assuming by patch the SNB FB kext, I can use the already patched Kext you have as an attachment on the linked post? With that assumption - I installed that Kext to the extensions folder. I then tried to run the repair kext permissions and rebuild cache commands. But I had an error when running one of them :- Mikes-MacBook-Pro:~ Mike$ sudo kextcache -Boot -U / rebuilding //System/Library/PrelinkedKernels/prelinkedkernel kext-dev-mode allowing invalid signature -67061 0xFFFFFFFFFFFEFA0B for kext AppleIntelSNBGraphicsFB.kext File at path '/System/Library/PrelinkedKernels/prelinkedkernel' changed, cannot be used Child process /usr/sbin/kextcache[492] exited with status 77.

Hi there. First post here. I am a newcomer to the Hackintosh scene and recently built myself a E6220 with El Capitan using the info on this great site (and a lot of help from a friend!). I have had a few little issues which I had been working through, and am a little stuck on one which I was hoping for some help on. Basically I managed to add the kext file to allow VGA to work from the laptop docking station. But I still have 2 problems :- - The output only appears on the external display when I boot with the laptop lid open. - If I then close the laptop lid the laptop display is still active and I'm not solely on the monitor. Ideally, I just want to be able to leave the lid closed and just use the monitor when i am at the desk. Any help much appreciated. Thanks Mike
