X299 Big Sur Support

[madsl9394]

I just downloaded the folder of @djlild7hina
I deleted my EFI folder (first time without clover)
I updated the BIOS (including the patch)
I switched to the EFI folder of @djlild7hina
And I just clicked the Update button
And it works!

In the coming days of course I will get more of an idea about the performance of the system

But for now,
You just do not disappoint!
Never!

Mate... good stuff! Can you please check Netflix / Prime Video DRMs? It doesn't work for me in Big Sur but it worked on Catalina. I'm on Radeon VII MacPro7,1 without WEG

No problem :

I can choose both

Good News :
But choosing is one thing, does it really boot with the chosen one

Anyone know how to enable "Extreme" option in macOS for on AppleALC? This is available under Windows for Realtek but not macOS. Probably needs driver level updates?

I have got a problem on the boot process.

Sometime at the end of the boot process, after verbose, I get a problem. Basically I can describe 3 scenarios after verbose:
1) apple logo with loading bar and at the end of the loading I will get macOS desktop
2) no signal (as per monitor popup message) but after a second I will get macOS desktop
3) black screen (monitor thinks that there is signal but is black) and no macOS desktop -> in this case I need to use reset button

Of these I think that the right behavior is on scenario 1, so there could be something wrong with my setup.

My current setup is:
- OC 0.6.3 -> same problem on lower oc version
- BigSur Beta 10 (20A5395g) -> I'm sure that this happen on all betas
- RX5700XT -> only via I can test
- 2 monitors (main LG 4k monitor connected on first DP port with a DP cable, a TV FHD connected via HDMI on the second port with HDMI cable) -> If I disconnect the HDMI tv, I get the same problem
- MacPro7,1 smbios
- No WhateverGreen
- RX5700XT SSDT adapted for x299


My only guess is to use WhateverGreen, even if I read that isn't mandatory using MacPro smbios. Anyone had this kind of issue?

Hi mate!

I have the same issue... same 5700XT, 2 monitors, 4k LG and 3440x1440 ultrawide lg with DP cables and a FullHD TV via HDMI.

I am using WhateverGreen, doesn't help.

I believe It is related to NVRAM & Big Sur. I have 5 monitors ( 1x38"; 1x27" 2x24"; 1x7" ) with a RX580. I have similar symptoms when I switch from OS Mojave or Catalina to Big Sur. Only 3 monitors out of 5 reach Mac OS desktop. Unplugging & replugging monitors are of no avail. I have to do a NVRAM reset or completely shut down the Hack, unplug power cable for few seconds & restart. Only then, all my monitors reach macOS desktop & all consecutive boots of BS are working fine.
Never encountered this issue with previous OS. Using WEG & ImacPro1,1

I have the same issue with only my main monitor connected. Only three days ago I added the TV as secondary output

Dell Alienware Area 51 R-4 is running 11.0.1 with a couple of things I am still working on. This is a MSI X299 with Killer 2500 Ethernet and Qualcom WiFi and Bluetooth.

Maybe I found a workaround, but needs some more test.
On my Asus X299-A Prime, disabling Serial Port in Bios -> Advanced -> Onboard Devices seems to fix the problem.
I rebooted 7 times yesterday and 3 times this morning. During night I unplug from the power outlet.
As for now I haven't got any black screen, usually I got a couple every 3-4 good reboot.e

Long story:
I read that others with the same issue have fixed by disabling Serial Port in bios. For what I remember on Catalina amend Mojave I had the Serial Port disabled but before upgrading to BigSur I decided to upgrade also the Bios and decide to leave Serial Port on since I thought it did not give any problem.
