What layout id are you using? In my EFI i mapped the audio layout-id directly to my pci device in DeviceProperties - if you copied mine just double check the paths to the audio pci device are correct using hackintool failing that, you can set the layout-id in the boot arguments

More information can be found here https://github.com/acidanthera/bugtracker/issues/1137 this patch disables MTRR update action which performs the Intel recommended procedure for changing the MTRR in a MP system. Its the system which controls how access to memory ranges are cached by the CPU...

Upgraded to OpenCore 0.6.2 and latest kext, no issues!

A few reasons to note: those kexts are new and were not available at the time of building this machine itlwmx is slow because it only operates over 2.4Ghz the intel bluetooth module would sometimes not load on boot, issues with firmware. After disabling the onboard bluetooth the system is much...

Are you able to see the device with hackintool? I am not doing anything special, nor did anything change from 0.6.0 -> 0.6.1 which would affect bluetooth Check that the kexts are up to date:https://dortania.github.io/OpenCore-Install-Guide/ktext.html#wifi-and-bluetooth Failing that, are you...

F20 works, but is inconsistent. I often got graphical glitches and I was unable to boot into safe mode. I've since reverted to F11 BIOS. Since the board contains a switch for the BIOS you can try with both F11 and F20. I think your problem is with RebuildAppleMemoryMap as newer BIOS have trouble...

Updated for OC 0.6.1, I went through Differences.pdf and there's nothing additional to add for this board

It's a custom power play table for my RX 5700 (non XT), I've not bothered to include it as I've found it to be unstable compared to the default apple provides

At the moment I don't believe the 3990x is supported, the only way for it to currently work is to boot macOS as a virtual machine

You can edit your power play settings using this spreadsheet to get exactly what fan curve you want https://www.insanelymac.com/forum/topic/340909-tool-amd-radeon-rx-5700-xt-powerplay-table-generator/

Geekbench results lie, use a real test instead. I posted here along with others also making similar claims https://forum.amd-osx.com/index.php?threads/guide-opencl-metal-performance-increase-on-5700xt.387/

Thanks for checking it out, if you check Console.log for "SidecarDisplayAgent" "SidecarRelay" and "avconferenced" you will notice the errors, from what I can work out the problem is due to the unsupported VBIOS of the GPU in macOS. I don't have another GPU to try, but I suspect that it would...

I woulds suggest F11 BIOS because F20 has problems with recovery mode and installer

F20 BIOS Disabled Fast Boot Secure Boot CSM Enabled Above 4G decoding XHCI Hand-off F11 BIOS is also fine

Option C would be to disable it with a custom SSDT and buy something like a T919. I can upload the patch tomorrow

Updated to 10.15.6 OK - had a slight graphical glitch on the installer, however this did not affect the actual upgrade. I left it to do it's thing.

If anyone is interested, I recently took some photos of the computer:

I only ask because I have the same WiFi card, CPU and similar Navi GPU and I seem to have problems with SideCar because of a driver issue which is present on the OS. (3950x, Gigabyte Aorus Master X570, Catalina 10.15.5, OC 0.5.9) I am currently running a 34" UW monitor but would find it useful...

Great choice of CPU & Cooler! I'd be interested to know if your SideCar works OK?

I can't remember which artist I found this from, I believe I downloaded a wallpaper resource pack from reddit
