Big Sur OpenCore Gigabyte Z370 Aorus Wifi + Gigabyte RX 580

[aftamohd]

I am sorry but I am finding it little hard! I now have a bootable USB for Mac OS Big Sur.
can you share your OC files since my board is the same ? Can I just use it or ...
I did see the guide but it is not helping me. from the guide should I use comet lake ?

 

[aftamohd]

I used the EFI folder provided and I am now able to boot but the language is German ....
I did edit the config.plist file and did change it to prev-lang:kbd to en-US:0 but still it boots in German language... any advise...

 

[P1LGRIM]

I did edit the coffin.plist file

 

[aftamohd]

sorry for the typo,.,.,, I meant config.plist

 

[aftamohd]

after spending good amount of time, I found that we need to clear the NVRAM and I was able to change the language.

installation suceeded but when I boot via Big Sur.. it keeps rebooting....

Boot your system in verbose mode by adding -v to your boot arguments and provide us a picture of what happens at the end when it decides to reboot. I am not sure but it looks to me like the install log you posted does not show anything wrong. And if you are using the EFI the op posted Big Sur should work if you have the same board.

let me share that quickly... one quick thing... I already have a Catalina running on M2 ssd and I have one more on which I want to install Big Sur to ensure all works ... I noticed that my Catalina was basically configured as iMac mini but now I see that as iMac Pro.... I can boot Catalina and it works though....

looks like an error with USBxHCI...

You could likely boot it with nothing or a bunch of miss matched information you just might have issues with iCloud services. In saying that I do not think it is your USB but if you do then remove the USBports.kext then it will just boot with default USB ACPI and that's no big deal. You might also want to remove the RX5700xt file in the ACPI folder and remove it from the config. If you have the same board as the OP then maybe something is not right in your bios because their EFI should boot your board except maybe for the different video card. Use the link below to check your bios settings are set correctly.

Many thanks for your inputs @scottkendall
I am running Catalina on the same bios so that should not be an issue right ?
I formatted the SSD, did install again and I see these errors.
