That actually looks okay, I think! But perhaps the refresh rate is 30Hz instead of 60Hz. Please check About this Mac --> System Report --> Graphics/Displays.

Ah, I think you are right. I'll check it later tonight.

Geekbench is good even with 16GB of RAM.

Great Job Casey!

The new Mac Pro just seems overrated and overpriced!

If only Apple had used an AMD Threadripper (including yesterday's announcement of 3990X with 64 cores and 128 threads) with TRX40 chipset and PCIe 4.0! Apple has such a good relationship with AMD for custom dual-Vega GPUs, so why not go all the way??

I disabled the AppleGFXHDA kext, losing HDMI/DP audio in the process (which I don't use anyway) and I didn't have any issue since.

Thanks for the tip. I don't need HDMI/DP audio anyway, so I'll give that a go. What's the best method to disable AppleGFXHDA?

I made a disaster!
I tried to solve the problem putting the file VirtualSMC .kext in /L/E i reboot and I got a black screen.
Then I tried to rescue the system with a time machine backup, I had catalina, other disater so I reinstalled everythig from usb key of mojave. After a complete configuration, I tried to update clover and a little disaster again the pc mboot very slowly and to power of I need to push power button.
I think the problem is in /EFI/Clover, here below the content, can anybody help me to solve?

I don't see any reference to refresh rate but I noticed the GTX is running at X8 instead of X16.

Hello @CaseySJ,

Having a very strange issue with my build (9700k, Arsock Vega 56) where the USB ports will completely lock up, but they only seem to do so when I am in Logic Pro X working in a session. The system is still completely responsive if I VNC in from another computer, so I know its not a kernel panic. It seems to be at random, sometimes happening a few minutes after launching Logic to a few hours later. It mostly appears to happen when I am hitting keys on my MIDI controller.

I read back in the forum and found a possible solution by using OcQuirks-4 and FwRuntimeServices in combination with BIOS version F8. This appeared to work at first but a little while later the same thing happened again. I have also tried the suggestion by totototo to revert to F6 with FwRuntimeServices + OcQuirks-Test-1 with no change to the behavior of the system.

The correct way is to override it with a dummy kext or a patch in your config.plist. The dirty way is to simply move it out of the /System/Library/Extensions/ directory and rebuild the cache.

Please note however that this fix is intended only if you observe random freeze related to hardware accelerated encoding/decoding with the following error in your system log when freezing :

localhost kernel[0]: (IOAcceleratorFamily2) <IOAcceleratorFamily2`IOAccelFenceMachine::fence_timeout(IOTimerEventSource*)> void IOAccelFenceMachine::fence_timeout(IOTimerEventSource *): AMDRadeonAccelerator prodding blockFenceInterrupt

I'm not sure it will do any good for you sleep issues and even if it does, there's probably a better way to fix it.

They need a certified Intel chipset to support Thunderbolt™, it rules out any possibility of an AMD CPU. That was a case at least before Intel released the specification to the USB-IF last year and it will definitely change once it will be integrated in the USB4 standard.

You shouldn't install any kext in S/L/E, they should go in L/E.

And use your available labels. In the attached image the green ones are hack related.

It makes it much easier. Just pick a new color each time you manage a new upgrade. Color the kexts before you place them within L/E and you only need to rebuild once.

I also opt for manually dragging to L/E to install and rebuilding using Hackintool's Tools > Rebuild (last lego block on the Tools screen)
