Boot error - missing "usr/standalone/OS.dmg.root_hash"

[yabogsegodnia]

Hello, I am trying to install macOS using your guide, but I ran into a problem. The system fails to boot and shows the following error:

[EB.RH.PF] usr\standalone\OS.dmg.root_hash
[EB.RH.MF] ("usr\standalone\OS.dmg.root_hash.x86 legacyap.im4m")
[EB.LD.LF|IN] 0 1 <"usr\standalone\OS.dmg.root_hash"> <"0">
[EB.LD.OFS|OPEN!] Err (0xE) <"usr\standalone\OS.dmg.root_hash">
[EB.RH.LRHIP!] Err(0xE) <- EB.LD.LF
[EB.BST.FBSI!] Err(0xE) <- EB.RH.LRH

I checked my EFI settings and set DmgLoading = Any and SecureBootModel = Disabled, but it didn’t help. Also, the usr/standalone folder is missing, so the required file OS.dmg.root_hash is not present.

Could you please help me solve this issue? Do I need to modify my EFI settings or use another macOS image?

Thank you!

did you find a resolution? I have the same problem, I think it was after updating qemu, but maybe a coincidence.

Update: I switched to qemu 8.2.2 and I'm booting again
