Hi

Programs no more, only terminal command.

Great guide.

Muito obrigado.

Un saludo.

Umm, how about:

Change .raw extension to .dmg

Mount image with Disk Utility -> Restore to Flash Drive.

It won't restore EFI partition and boot sectors (drive won't be bootable on hackintosh).

thanks very useful knowledge

[kidimon]

Am I only one who is having problems to make bootable usb? I write ''% diskutil list'' in terminal and it comes up as no such job.

Is there a fix for that? what am i doing wrong?

Thanks in advance

hello

the # is the prompt line command

just write the command

diskutil list

good hack

Saudações!

Uma pergunta "estúpida": essa imagem raw é para PC Intel apenas ou serve para notebooks também?

Se sim, é só instalar as kexts necessárias para touchpad etc?

Obrigado.

[pernacabeluda]

Ela instala apenas o sistema original, sem modificações. Você precisa instalar as kexts necessárias para o seu hardware, independente de ser laptop ou desktop. As kexts e boot loader incluídas na imagem servem apenas para o boot do instalador e boot inicial do sistema através do pen drive.

Hello,

Does anybody know how do i burn the .raw image (that i wrote to USB successfully thanks to this guide) back to DVD?

Tnx

[erroruser]

[ref]royorlev[/ref], just store your usb in a safe place

[royorlev]

Is it possible to write the .raw image back to cd/dvd?

[MichaelStewart]

Is there a way for me to be able to tell when the process is finished, will it prompt me in Terminal or do I just have to keep checking with Control+T until it stops?

[erroruser]

[ref]MichaelStewart[/ref], make on usb an use either win32diskimager or etcher

this makes 0 sense- why use a raw file with no real instructions on how to extract and utilize???

.raw is .dmg, just renamed

use Balena Etcher instead

[brian k]

downloaded the raw file , changed to dmg, made bootable drive with the Ventura install and copied the contents of the

efi, still stuck in boot loop, gets into the 29 minute install portion, then does a continuous restart but never gets to where I can boot from the install drive.. please advise

Windows does not show up my usb drive after I flashed the raw img to usb via Etcher. it does boot up macos and shows in Device manager, but I just cannot see it in windows file explorer. i just wanted to copy my efi folder to the usb. also the efi I made doesnt show internal drives on my laptop, googled a lot but no solution works

How do you make MacOS bootable installer for offline install in Windows? I have dmg image of MacOS but Mac installer doesn't see it correctly on USB. 

is there a step by step how to do this on Windows?

[electrovalent]

No bootable device found using vanilla high Sierra  on legasy boot.

Flush raw file with etcher

[gbrchagas]

Can I use Rufus instead?
