[solved] Alienware 15 R2 install EI capitan&install Mac Sierra Success

@RehabMan
I am actually trying to debug HDMI audio with Toleda. Just wanted to ask for your experience on this. Here is the situation:
-In my laptop HDMI audio is controlled by the Nvidia Discrete graphic Card whereas CA0132 is the audio codec for the the rest (Speakers, line-in, etc.)
When looking at the DSDT and the SSDTs, i don't have any mention of B0D3 that is supposed to be renamed as HDAU. However, i have a Device (B0D4) in the same section than Device (IGPU) , under SB_PCI0. IS it this one that is a substitute of B0D3 ?
I went through different threads to find other potential names for HDMI audio in DSDTs but i could not find any. Also, the only way to have HDAU displayed in Ioreg is one i put it under SB_PCI0 along with Device (IGPU). Putting it anywhere else (ex. Scope (\_SB.PCI0.PEG0) will have no effect. Note, I also put Device (GFX0) under the same scope and this one is taken into account, the Device (HDAU) is simply ignored.

Attached the ACPI tables i use, can you direct me on this ?
Side note: i am not using any ACPI patches through Clover.

B0D3/HDAU/IGPU has nothing to do with discrete graphics HDMI-audio...

Not sure to understand. Do you mean that i don't need the Device (HDAU) for HDMI audio from the discrete graphic card with the web drivers ?
The only other think that i may think of is AppleHDA binary patching...

HDAU/IGPU is related to Intel HDMI-audio.
You said your HDMI port is attached to Nvidia.

Implementing IGPU HDMI-audio is nonsense if the HDMI port is not attached to it.

Ok, i will take that into account for my next trials. I am actually facing a weird issue when i updated my Bios (suspecting the actual version to prevent HDMI audio in OSX). Everytime i try to boot into OSX i get the following screen:

Which is clearly related to the intel graphics. I did not change anything in my injection method though

When i try to boot in safe mode i get this screen, any clue ?

No idea. Do a fresh install for comparison.

Even booting to the installer ends up with the same kernel panic...

Check BIOS settings, reset BIOS, do EC reset...

Ok guys so here are the files (read notes in the bottoms before downloading):
-The EFI folder (you have to generate the serials numbers for the Macbook pro 11,1)
-The working kexts (audio, ethernet, battery)

What works so far:

-Bluetooth
-Audio (all ports + mic and sound volume control)
-CPU power management
-Boot from Nvme SSD
-Sleep
-Graphics (HD530 for internal display + 980m GTX for HDMI VIdeo out - you have to use the nvidia web drivers)
-Keyboard (i use VoodooPs2 from Rehabman, only tap from trackpad not working but it's not important for me)
-All USBs
-Webcam
-Battery
-Brightness control
-Full hardware recognition (RAM, etc.)
-etc

Not working:

-HDMI audio ( i give up for now, if anyone want to pursue you're welcome to do so). So far i managed to have the nvidia display show in Ioreg with hda-gfx but could not have either HDAU to load in ioreg or have the nvidia codec to show in DPCImanager (weird enough, there is a 2nd intel codec that shows up).
-WIFI ( i have killer 1535, waiting for a broadcom card to be shipped)

Once you are done installing Sierra, install the web drivers for nvidia then change the boot arguments by removing nv_disable=1 and putting nvda_drv=1 instead).

Enjoy.

Note1: I used karabiner elements to remap the keyboard keys like a mac, works like a charm.
Note2: Files tested and working with Bios 1.3.6. I tried with the older Bios (1.2.2) but i could not boot to OSX).
Note3: the ssdt.aml file is for an intel 6820HK. if you have the 6700 version use SSDTprgen (from pikeralpha - https://github.com/Piker-Alpha/ssdtPRGen.sh) to generate yours.

Hi slayer23a. Could you please post your updated EFI partition files? I have the alienware 15r2 and installed macos Sierra. I used your EFI files already in your last post but after installing Nvidia drivers I started to get the same kernel panic as you had, with message about Intel graphics. Also, I could not get sound working. My model has 6700hq processor, 970m and sound blaster recon3di .

Thanks in advance.
