 don't work for me too... 

Found a bug, YouTube don't work ...

 

it's maybe a misconfiguration in your config.plist or some missing kexts. For me I have no problem with yt or any other video/playback/streaming services whatsoever.

I used vandroiy2012 .image and everything works. (WiFi, USB, Sound, etc.) But I can't make a boot in Recovery. When I try to boot in Recovery I am getting OCB: LoadImage failed - Unsupported error.

 

Second problem mount -uw / doesnt work always giving an error 66. Actually I want to boot in Recovery and disable authenticated-root but I can't boot in Recovery. 

 

Guys is your Recovery working? or anyone knows to disable authanticated-root without boot in Recovery?

Installation went fine even though last part of the installation process was blind because screen turn black although I can still see it works. After a while screen turns off and when I press something turns on again and shows black screen, sometimes I can see the mouse cursor on the black screen.

 

Booting up again after installation is a success but still black screen although monitor turned on.

 

I have a AMD 5700 XT.

 

Anyone seen a black screen and fixed it?

I did. This happened to me. You have to add two keys to your NVRAM, "booter-fileset-basesystem" and "booter-fileset-kernel". If adding via CLI, use base64 encoded value AA==. If adding via Xcode, use <00>.

 

If you don't have these, Lilu won't load, neither WEG will. So a black screen with the mouse cursor until you click on the screen (but you still can see the mouse moving on the second screen).

Recovery does not work ATM, since it uses same approach as Install and therefore offers no injection from OC.

Hi
Can someone help me to fix this?

 

It's my first time using opencore and I'm stuck here with Big Sur

I already installed the os with VM on my SSD but i cant boot it now

You need to set the config file properly, You're missing config properties under "Kernel>Add" read about it on open core guide for your processor.

How to fix intel UHD 630 for macos big sur?  I have Catalina run without any issue with the same setup and open core.

 

I am stuck at multiple apple logos (8 of them) with lines on each apple logo. before the 8 apple logos showed up, it was one apple logo with progress bar. it reached to 80% then screen flashed to the multiple apple logos.

 

changed both 07009B3E and 00009B3E

 

booter-fileset-basesystem and kernal added as well.

 

please help!

Hi guys,

Anyone of you lost audio with Big Sur?

 

Only in Firefox without normal audio output, the others including Safari and Google Chrome are normal.
