Thanks for the report! Looking at the log you pasted: I don't see an actual kernel panic here — everything is still pre-kernel EFI/bootloader logging (AAPL:/OC:/OCAK: lines), and the log ends right where its ~256 KB capture buffer runs out (LOG:EXITBS:START), not necessarily where the boot actually fails.

The Err(0xE) on usr\standalone\OS.dmg.root_hash during the OS Installer 2 phase looks concerning, but this exact sequence has shown up before on a device where the boot actually continued fine afterward — it turned out to be harmless log truncation rather than the real failure point.

To pin this down, could you:

1. Describe/transcribe exactly what the screenshot shows — the actual on-screen error text is what's missing here, since the pasted log doesn't contain it.
2. If possible, reproduce with -v (verbose) boot-args, and if you have a second Mac available, capture the log over serial/network instead of relying on the on-screen buffer, so it isn't cut off at the same point.

That will tell us whether this is a real OpenCorePkg-side bug or something else (root patching, installer media, etc.) — I'd rather not guess at a fix without knowing what's actually failing.

So my Mac stop install in apple logo and progress bar 29%. Later they open this recovery..

I don't use SMBIOS, but I'm using spoof level: Moderate.
I make all in instruction but it's don't work, later i trying now and send you logs and details (Sorry on errors, English not my native language)

I totally understand you. My native language is not English as well.
My English is my third language, I speak both Bulgarian and German better than English.

@Ang1l3ff can you try whether with the latest release it gets stuck here?

[Ang1l3ff]

Moderate

Yeah I can, but later, maybe today or tomorrow
