For my Asrock Z490M-ITX I found this workaround for getting HDMI to work:
In the EFI/OC/Kexts section add:
”FakePCIID.kext" and "FakePCIID_Intel_HDMI_Audio.kext"
and declare them in the Kernel/Add section ("FakePCIID.kext" before "FakePCIID_Intel_HDMI_Audio.kext")
Still in the config, in the...
Try to boot with Fake-id 0x12345678 (you can add it at Clover boot screen) and when you reach the desktop rebuild cache from terminal with:
sudo kextcache -i /
and reboot.
No kext and config not configured. Try with the attached EFI
It is possible you have to boot with Fake-ID 0x12345678, you can input it at Clover Boot Option;
than rebuild cache with terminal :
sudo kextcache -i /
and reboot without Fake-ID
Analog and HDMI audio are working fine on this laptop with vanilla/original AppleHDA, Lilu + AppleALC (in EFI folder, not in L/E or S/L/E) and Layout-id 29
For the Display PrefPane take a look here:
Display Prefpane can't load. Found the problem and solution.
For ALC271x you can give a try to AppleALC; you need the original AppleHDA and injecting Layout-id 31 via config.plist or DSDT. Be sure there are no patches for AppleHDA in the "Kernel and...
Not exactly, you need only an istance of aDummy, better installed in S/L/E (or in L/E). The config provided from the patcher contains only the patches for your codec, so you have to add it manually to your config. Other way you can let the patcher doing the work, dragging your config in the...
It depends probabily on the fact that sierra broke support for -xcpm for Ivy-Bridge.
Do all the steps as described in the linked guide:
https://github.com/Piker-Alpha/ssdtPRGen.sh
when you perform the command use the parameter "-c 2" (without quotes). Be sure you don't have "-xcpm" selected in...
Why are you using an iMac system definition? Your laptop is more like a MacBookPro9,2. Try it with ig-platform-id 0x01660004 (inject intel must be flagged). 0x01660003 is better for low resolution monitors
You can give a try with to AppleALC.kext (google for it). Download the kext and put it in kexts/10.11, than you have to alter your Layout-id according with the info you can achieve looking in AppleALC.kext/Contents/Plugins/PinConfigs.kext/contents/info.plist.
You must have an original AppleHDA...
