Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

[CaseySJ]

@CaseySJ
I am using Gigabyte Vision G and I have also mapped all the required ports correctly using your SSDT UIAC V2 for Vision G. I made my own USBPorts.kext using Hackintool and I use that one instead of any SSDTs. My hack works perfectly in all areas in Big Sur Dev Beta 6 / Public Beta 2. However, it does not go into sleep mode correctly. The screen turns off, but all motherboard and USB Keyboard / Mouse RGB lights remain ON.
I am also using your SSDT-USBW.aml and USBWakeFixup.kext. I have also injected correct power properties using Hackintool which were shown red previously. I am using iMacPro1,1 as SMBIOS and disabled bluetooth to wake up this device.
I am facing EXACTLY same problem on my other hack Gigabyte Z370N Wifi. I am using latest Official OpenCore 0.6.1 along with all latest kexts released yesterday.
Any pointers?

Hello @mirwaiz

• Does the problem occur when using the USB SSDT (SSDT-UIAC-VISION-D-V2) instead of USBPorts.kext?
• In OpenCore Configurator --> Kernel, is XhciPortLimit checked ON?

Do you have the parameter igfxfw=2 in Boot Arguments?

I do

I will be building a machine sometime this week. I have read all 200+ Pages in this forum. Back a few pages people are talking about using iMac20,1 instead of iMac19,1. However the instructions on pg1 say to use 19,1.

I will be using a Z490 Vision D
Radeon Nitro+ 5700 XT
i9 10850k
64gigs of Ram.
3 NVME drives for a triple boot system Windows, Linux, OSX

Should I consider using iMac20,1 or even iMacPro1,1?

Thanks for this great package @CaseySJ

I do

Do you see an IGPU utilization spike when playing the Sony 4K Camp video?

Hello @taconugget

I think it's quite safe now to use iMac20,1 or iMac20,2. At the OpenCore Configurator --> PlatformInfo page, simply choose it from the pop-up menu:

Playing the video takes the iGPU up to 0.15Ghz (as does rapidly scrubbing/shuttling).

Maybe there is something in the latest Whatevergreen that changes things?

Without igfxfw=2 I get all sorts of weirdness (playing the sony 4K camp file). I'm inclined to think there is a bug somewhere or that the microcode isn't updated for Comet Lake yet?


Edit: I think the actual performance is fine though; converting a 43min 1080p H264 to H265 (HEVC) will supposedly take 14 minutes, IPG is showing GFX AV of 3.42 and GFX Req showing 1.03 at the time of writing.

Hey everyone.

Today I replaced my old second monitor with the same model as my main monitor. Previously I was able to use NativeDisplayBrightness application to adjust the brightness for each monitor. Now when I try reducing the brightness, it is only changing it for the main monitor. I also tried using MonitorControl, it shows that the two monitors have different ID numbers, but when I try changing the brightness on each option, same as before, it changes the brightness of the main monitor. Any ideas on what I could change?

Also any recommendations on how I can use the speakers on both monitors at the same time? On the volume output it only lets me select one monitor's speakers.

Edit: When I only have the new monitor plugged in, the NativeDisplayBrightness works fine. I plug in the other monitor and it goes back to only changing the brightness for one of them.

Interesting problem. Do you have a real Mac for testing this? One option is to report the issue to the developers of both tools:

• NativeDisplayBrightness issues -- Unfortunately the developer no longer has time to support this project as stated in this TonyMac post.
• MonitorControl issues - Please search that link first in case there are any similar reports

Not possible.

Thanks for those resources Casey. Apparently it was a bug caused by having two identical monitors and they pushed a fix (MonitorControl).

Link to the fix in case anyone experiences the same bug.
