Do you have any news for us? I still can't boot the installer

It didn't change the situation for me. I still get stuck on a black screen

Each time the log is different. At some point, progress reached a gray screen with a cursor, but then nothing changed. I attach a screen from the last video. I have tried different smbios. Therefore, the information in the logs may differ from the EFI folder.

I own Navi for a long time and tried to run it with different parameters. Including, I tried launching with the natively supported Nvidia GT710. Black screen anyway. I've tried various variations but no result. On top of that, my Chinese nvme with catalina apparently commits suicide. What bad...

Could you show EFI for your B75? I passed the kernel panic due to UNC0, but I still can't get the system to boot (stuck on a black screen, but the problem is not in Navi). At the same time, Catalina starts successfully

I confirm that on the x79 platform (b75 chipset) the kernel continues to panic with SSDT-UNC.aml. I attach a screen. Check ACPI for analysing from this post, please.

Obviously this dsdt won't work with my x79t. Fix my acpi. So I can try and report about work after fixing.

I have the same problem on x79t (Chinese board based on B75 chipset, LGA2011, Xeon e5-1650v2, 4-channel ddr3). The problem could not be resolved, but Catalina works with this bootloader. I am attaching my EFI folder and video log. I need this update, so I want to help in solving the problem as...

Anyone faced an issue from this thread: https://www.tonymacx86.com/threads/2-problems-after-upgrading-to-catalina.292195/ ? For several months now I can not achieve a solution to the problem with lock screen password input It looks like this is related to Navi or AMD drivers in general. I would...

I have the same problem with my RX 5700XT. Password entry is slowed down when entering characters. In addition, there are some freezes on the screensaver (on password entry). Has anyone found a solution?

At 10.15.2, there remained artifacts with dynamic wallpapers and a screen frequency in 2K resolution. Any ideas? UPD: I did as written here: https://gist.github.com/ejdyksen/8302862 Dynamic wallpapers are now without artifacts. But I can not change the frequency of the screen. Booted under the...

"HP" gives the noise of the headphone jack on the front panel. "Mic" gives nothing. "Read" also gives nothing :( Attach files

Ok, I pasted these 3 files into the clover. But there is no desired result as in your screenshot. In addition, I found that the jacks on the front panel were connected to the built-in sound card all this time :( Now I fixed this. The microphone on the front panel does not work, but there is some...

UPD: I replaced the old ssdt with the one you sent. I attach files UPD2: Everything remained the same with the sound except one: strong noise on the left channel is observed at one of the outputs. This is likely a rear R/L output.

Should it be along with what you sent earlier? Or replace the old with this?

Is there anyone who would help us with this? I am ready to do everything that depends on me, just tell me how.

UPD2: Only the microphone still works. Be sure that I checked the signal on all the jacks. I attach files

I tried all the jacks, optics and jacks on the front panel. Nothing works except the microphone UPD: but I have not tried kext from your post yet

This is beautiful. Now Voodoo? If so, then everything is still the same: the microphone works. Other jacks do not play sound. Optics also have no sound. Dump attached

This changes to HDEF only if i use AppleALС. In all other cases, it is not renamed and looks like in the screenshot that you showed :(
