pastrychef's Asus ROG Strix Z370-G Gaming (WI-FI AC) build w/ i9-9900K + AMD 6600 XT

Thanks for the speedy reply!

I've double checked all 3 directories and deleted the duplicates now only using /EFI/CLOVER/kexts/Other/ -
But this had resulted in boot loop so had to add lilu + AppleALC back to /Library/Extensions/ & /System/Library/Extensions/

Screenshots of kexts folders attached.
Also uploaded config.plist

Separate issue after recently upgraded Vega 64 (reference version) - Freezes at Heaven benchmark and various games, but not Cinebench R15, suspecting it's a power/fan issue - currently using VegaTab_64.kext as instructed in the guide.

Thanks again!

• Remove all the hackintosh kexts from /System/Library/Extensions/. They don't belong there.
• Remove Lilu.kext and realtekALC.kext from /Library/Extensions/.
• Remove IntelGraphicsFixup.kext from /EFI/CLOVER/kexts/Other/. Make sure you have the latest versions of AppleALC.kext, Lilu.kext, and WhateverGreen.kext in this folder.

It looks like you followed instructions from multiple sources. That's a bad idea. Everyone does things slightly differently. I suggest looking for one guide and follow it. Do not mix and match instructions from multiple guides. This will just lead to the mess you currently have.

If you want to use this guide, remove all hackintosh kexts from /Library/Extensions/ and /System/Library/Extensions/. Use the config.plist that is included with my EFI folder in post #1.

Cleaned up all kexts as instructed, and finally have audio working!

But still can't get Vega 64 to run Heaven benchmark without freezing, after reading up your guide on VGTab so tried that as well as RadeonVega56AirCoolingFansFix.kext - Fans are working fine but just freezes when under full load?

My settings for VGTab are not guaranteed to work for others because I applied Liquid Metal thermal compound to aid in cooling.

Also, as with CPUs, each GPU will clock slightly differently from other GPUs even same model from same manufacturers.

Therefore, it's best if you adjust VGTab for your own specific Vega card. Try starting off without any changes to the clocks or voltages and just adjust fan speeds and target temperature first.

Thank for the tip!
So are VGTab and RadeonVega56AirCoolingFansFix.kext the same as in manually modifying the fan/power controls?
And do you think the freeze issue is to do with power/fan so if I try test out the fan speed and target temp there should be a sweet spot which should stabilise the card?

Cheers

Yes. If you are familiar with the WattMan utility in Windows, VGTab allows users to make the same sorts of adjustments to Vega cards in macOS.

Yes, it's very possible that the freezes can be due to improper clocking, application of voltage, and/or fan speeds. I really don't know of any way to find a "one size fits all" setting for all Vega cards. Even AMD overshoots with voltages to ensure that all Vega cards run at advertised speeds. The only real way to find the "sweet spot" for your specific card is through trial and error.

First, make sure there's nothing wrong with the card itself. You can do some testing in Windows and/or use the Vega card without a fan fix until you are confident that the card is not faulty. Then, you can experiment with VGTab and adjust the fans. For me, I was able to set idle fan speed at 800rpm and target temperature at 55C and temps were still reasonably good. After that you can experiment with undervolting and/or overclocking.

Make sure you installed the correct version of the Nvidia web drivers that matches the version of High Sierra you are using.
Please see this list:
https://www.tonymacx86.com/nvidia-drivers/

I installed the correct version for the High Sierra (17G65). The problem persists. Tips? Do I have to update to (17G3025) and try again with the new drivers?

I tried to do an installation without your EFI folder and I have no startup problems, but in this way I lose all the improvements you've made to the configuration.

As per the forum rules, please fill out your profile with your CPU, motherboard, and GPU information so it's easier for others to help you.

When you boot in to macOS with your clean install, are you getting acceleration from your video card?

 

[pastrychef]

I had to RMA my RAM and am currently running on 8GB of very cheap RAM. It's interesting to see how much of a difference RAM makes to Geekbench scores.

No, I just installed the clover bootloader installation with multibeast as the official guide says.

If you are not getting acceleration, it's essentially the same as nv_disable=1 where the Nvidia web drivers are not being used.

Try installing the Nvidia web drivers on the Clover installation and see if they work.
