PLEASE HELP

BigSur22 should be diskX where X is a number listed for your BigSur22 disk.

Not "BigSur22" you must use own dev/diskname. (disk5 or disk2 etc.) or share your diskutil preview here.

Same happened to me when I mounted the DMG.

Also when restored the image to the real disk.

[MorenoAv]

Well I'm back and the restore worked, because I'm writing this in my macOS Big Sur...thanks to @MaLd0n, but now I have two problems : how do I change the name from test to macOS Big Sur, and how do I expand the installation that is only 120 GB and my ssd name is 500GB, and last how do I change the screen name from admin to my own...

Thanks I really appreciate all the help you guys give me...

Cheers

You probably can add another admin (you) and remove the other.

To resize:

Resize Disk After restore Thanks to Pavo

To resize the physical disk of BigSur when using this method
*Identify the physical disk
diskutil list
*repair the physical disk partition
sudo diskutil repairDisk diskX
*Resize the physical disk container volume
sudo diskutil apfs resizeContainer diskXs2 0

And how did you got rid of the errors you mentioned when mounting the .DMG file?

Every single time I mounted the DMG to be restored it gave me the error. Probably because I am booting Catalina with Clover?

vc tem de dar restore na partição de 120gb e não na outra

quando se monta o .dmg ele cria várias entradas, veja o tutorial, use um espaço maior que 120gb pra evitar problemas

Sim, estou usando um HD de 250GB e fazendo o restore da de 120Gb.

Vou observar mais uma vez depois dessa tentativa

 

[telepati]

@MaLd0n is your "sudo mount -uw /" working? When I try I am getting error 66. Second question can you boot in Recovery? When I try to boot in recovery "OCB: LoadImage failed - Unsupported" error coming. is there any way the fix both issues?

[RandomTech7]

Thanks Mald0n! You are the God of Hackintosh, I know what I'm saying.

I get still waiting for root device and the prohibited symbol. ASRock B450M Steel Legend, Ryzen 7 2700x, GT 710. AMD patches are done. what could be the issue?

Consegui bootar aqui.

Usei a pasta EFI e DSDT que estão no outro post eu acho, para a z390 M Gaming.
Verifiquei se as entradas de NVRAM estavam corretas e dei o boot.

Vejo vários erros no verbose, inclusive dá um erro logo após escolher o dispositivo de boot, algo de segurança.

MAS...

Como eu não entendi se isso aqui precisa ser feito já no novo sistema, ainda não fiz:

Compile OpenCore and Kexts, use these commands

Não sei se rodo agora pós instalação.
Até porque não sei se rodo isso no sistema ou na EFI (por exemplo, onde rodo o Olarila OC.command)?

E nosso amigo Mald0n disse que precisaria fazer um fine tune pois, minha placa é outra, é uma Z390 Gaming X. Como fazer isso?

Obrigado a todos que ajudaram a instalar.

(obs: não dá para trocar o nome do disco de "Test"?)

Eu consegui chegar até o passo do recovery, verifiquei o disco após terminar o processo, refiz as configurações do OpenCore, mais não vejo o macOS Big Sur no boot.

O que pode estar acontecendo?

vc deu restore na partição errada, veja o primeiro post. a sua deve ser o disk5 e não o 6
