[Success] 8700K, Gigabyte Z370-HD3P, UHD Graphics 630, macOS High Sierra, Mojave

[BenCharbo]

for audio i did that and it worked

"For sound install VoodooHDA-2.8.8.pkg and unzip VoodooHDA.kext-2.9.0d10.zip then replace VoodooHDA.kext in /System/Library/Extensions using any kext installer" (page 1)

for USB i don't know, maybe you should verify the wiring. I had a disk that didn't mounted in the front USB, i mounted it from the rear USB and then replugged it again in front and it worked ... mysterious ...

hope that helps

@rainbowflare first post has been edited to fix UHD Graphics 630 issue on High Sierra 10.13.4, which are as below:

Customize > System Definitions > iMac > iMac 17,1

SMBIOS > Select iMac17,1

Boot > Checkmark -disablegfxfirmware in Arguments section if MacOs is High Sierra 10.13.4 and use latest kexts (FakeSMC.kext, IntelGraphicsDVMTFixup.kext, IntelGraphicsFixup.kext, Lilu.kext)

I have the same mobo and am unable to get audio working AND all of a sudden my usb ports stopped recognizing external drives

Exact same problems..

I've been able to do everything except the Optional Patching DSDT And SSDTs step.

When I execute iasl -da -dl -fe refs.txt *.aml I get the following error:

Pass 1 parse of [SSDT]
ACPI Error: [TUSB] Namespace lookup failure, AE_ALREADY_EXISTS (20161210/dswload-462)
ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20161210/psobject-310)
Could not parse external ACPI tables, AE_ALREADY_EXISTS​

I'm pretty sure I need to do this because I have the following symptoms:

• On boot the login screen is very dark & unresponsive to the keyboard or to mouse clicks. If I let it go to sleep and then wake it up I can log in and both displays are working.
• After login, various sections of the screen flicker and artifacts appear/disappear.

dual displays enabled

@rokuhn Try below

iasl -da -dl DSDT.aml SSDT*.aml

I was able to complete the Optional Patching DSDT And SSDTs step. Unfortunately the login screen problem and the flickering problem didn't change.

Next step is to try the 4K patch to see if that helps with the flickering.

Sure is a lot that a newbie has to research before completing one of these mackintosh installs.

I also noticed that Atom and GitHub Desktop don't run properly. The icons will appear in the task bar but that's it. Github Desktop won't quit. I have to restart before it'll die.

Attached is the ELF I ended up with.

@rokuhn For System Definitions (SMBIOS) use iMac17,1 instead of iMac18,3

I think I'll start over.

Just in case it's of any help ... here's the log file.

I did notice that only one of the 9 SSDTs that I put into the PATCH directory generated a table.

The instructions showed 16 SSDTs. Maybe I didn't hold down the F4 key long enough to generate all of them.

I wiped the disk and re-installed. Now I have one monitor but it is well behaved. The about shows two graphics cards and one monitor.

I had that functionality when I completed the MultiBeast step. Nothing after that helped.

The ssdtPRGen.sh step complained about an unterminated search string. I just hit yes to continue. Looked like the SED string was in the message output routine so I don't think it affected functionality.

I did find two kexts that caused problems:

• NvidiaGraphicsFixup.kext - caused black bars on the display. As the name implies, not compatible with the Intel 630 display.
• AtherosE2200Ethernet.kext - caused some compatibility issues with the Atom editor and the GitHub Desktop application.

I only use OSX when testing cross platform compatibility so I'm OK with the current functionality.
