Hi Hans88,
I have your same cofiguration, only for me,: i7 5820k. Can you post/help me, the correct procedure to have video hw accelleration, and sound working...?!
Thanks.
Hi Lucke, sure I'd be glad! I assume you got success with all the preliminaries. So, I will skip that and go direct to the point.
First of all you need to make sure that you are using Clover as boot loader and make sure that these are included in your boot arguments: nv_disable=1 npci=0x2000 I would also recommend "-v" for the time being to see what's going, might the system hang up! Now in OS X make your update to 10.11.3 if you didn't yet. Download the latest Clover Configurator from this link
http://mackie100projects.altervista.org/download/ mount the EFI partition, Open the config.plist and change your SMBIOS to MacPro 6,1. Keep in mind that the Magic Wand might probably generate an invalid serial number and you might need to create your own serial number. This guide;
http://www.tonymacx86.com/general-help/110471-how-fix-imessage.html#TOP4.1 might be of great help to have a solid foundation and a valid/working iMessage is what would confirm this. Following this, go to RtVariables and insert 0x28 in BooterConfig and 0x3 in CsrActiveConfig to disable SIP. Save this config and reboot with the same arguments mentioned above.
Back in OS X, go to terminal and write this: "defaults write com.apple.finder AppleShowAllFiles YES" press Enter and relaunch Finder, this should unhide System folders. Go to System/Library/Extensions and save a copy of AppleGraphicsControl.kext and AppleHDA.kext.
Open Terminal, type this: sudo nano /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist (note that this is all on one line) and in the text search this line: <key>Mac-F60DEB81FF30ACF6</key> and change <string>Config1</string> to <string>none</string> press Ctrl+O and then press Enter to save the modification and Ctrl+X to quit. Now we need to rebuild the kernel cache; type this in terminal: "sudo kextcache -system-prelinked-kernel" press enter and wait, then this one "sudo kextcache -system-caches" and reboot with same arguments mentioned above.
Back to OS X, go to this link:
http://www.nvidia.com/download/driverResults.aspx/97587/ , download the latest driver and install. Before restarting, open Clover Configurator, open your config.plist go to "Boot" and enable nvda_drv=1 save and reboot. Now your graphics should work! I have guided you straightly according to our own specific hardware model. If you need the full guide;

For your sound make sure that there is nothing enabled for audio in Clover Configurator. Then, go to "Devices" and under audio type number "1" in inject then save and exit Clover Configurator. Go to this link:
http://www.tonymacx86.com/audio/143757-audio-realtek-alc-applehda-guide.html and head to "Unsupported/Non-working Realtek ALC AppleHDA" then "2. X99/Intel High Definition Audio (Workaround requires 1, 2, 3, 4, 5 and 6)" but ignore what's written and head directly to "2. ssdt injection (Any boot loader):" and download the provided SSDT instead of patching the DSDT. Open Clover Configurator, mount EFI partition and go to EFI/CLOVER/ACPI/Patched and paste the downloaded SSDT there. Now, download the attached AppleHDA.kext I have uploaded which was provided by Toleda. Download iKext or kextbeast app to install this AppleHDA.kext reboot and audio should work fine!
Sleep is still an issue I'm investigating in.
I hope I was able to help you.
