[gerard71]

hello MaLd0n quick question you gave me a dsdt for my gigabyte z270 gaming k3 is it necessary to add in addition the SSDs SSDT-EC-USBX.aml AND SSDT-PLUG.aml? under BIG SUR when the computer goes to sleep when I wake it up the processor starts up and crashes the system it looks like the processor management is bad thank you

hi, what about Big Sur with AR9285? I cant make it work!

i think if u disable protections yes

MaLd0n, eu refiz a instalação do sistema porque o comando para resize não estava funcionando... agora aconteceram umas coisas estranhas. o sistema "instalou", coisa que não estava acontecendo antes... só que ele não aparece por exemplo o meu HD direto pra dar boot, só a opção "Preboot", que eu selecionando ela consigo usar o sistema normalmente, só que o meu áudio não funciona de jeito nenhum! e antes funcionava! o que será que pode ser isso?

fiz esse procedimento, dava load na appleALC e na Lilu normalmente mas não tinha som, tentei voodoohda, não carrega a kext, coloquei um patch que você fez pra mim para o som no clover, aí ele reconhece o som fica como desconhecido no hackintool e não funciona de jeito nenhum o som, mas na instalação anterior funciona normal(fazendo restore)

eu me lembro que esse notebook tinha uma zica no áudio. tinha vezes que não funcionava por nada. o problema era nvram

Ola Maldon, qual parte na configuração do open core resolve problemas em restart. Porque solicitar o restart ele não sai totalmente e fica em uma tela preta após desligar o monitor. O shutdown  funciona normal. acredito que isto tem atrapalhado fazer o update das versões. Ocorre isto preciso apertar o reset físico da maquina.

I think we have the same issue.

Opencore boots fine, I managed to install until 12/13 minutes remaining, after that tries to boot, but crashes.

Then manual rebooting opencore loads fine there's a option for bigsur macos install select this and at the phase that the apple logo is already up the screen it crashes and can't even see the errors, because it's too quickly something with "sigakill: shutdown...!!!.

Been this week trying to figure this thing out, but no show!

Any clues?

EDIT: Since I can't make any usb to boot in my system, i booted from empty internal ssd, only with EFI populated, after that i use the usb  to make the installation to the internal SSD. Could this be the issue?

HP XW6600, 2xXeonE5430, 16 GB, 256GB SSD, Nvidia 710GT. 

EDIT2: I was able to get a picture of the final verbose, just before the screen become black. Can anyone make something of this, it's not very clear.

Nope!

I installed beta5 from an image from here, and it's working very well.

Unfortunately, until today, couldn't update in anyway.

Still trying to figure it out.
