OC: grabbed zero system-id for SB, this is not allowed.

[whosdev]

Hey there! Dunno if I'm just dumb, but I've made all the BIOS changes and I still can't boot. I've always get the same bug. OC: grabbed zero system-id for SB, this is not allowed. Halting on Critical error With the deprecated EFI, it used to boot, but whenever I tried to use the Main EFI it gave the same error. Currently using BIOS 1.53, unmodded.

What macOS version are you on? Are you on Catalina by any chance?

[yxyshadow]

@whosdev @yxyshadow @ljurcisin

Which EFI version is giving you this issue, the latest EFI?

Which EFi commit is the last working one?

[ljurcisin]

Latest EFI in my case + additional change for unmodded bios + "-v" boot arg + I think 3 additional kexts for enabling wifi and bt on stock wifi-card

last working was just the last one before Monterey related changes

So the latest EFI is giving you this?

@ljurcisin

Can you try setting SecureBootModel to Disabled and let me know if that fixes the problem?

[yxyshadow]

The latest EFI giving this error when update to Mon_12.0.1, last working:OC_0.7.2 , BigSur11.6.1

Lastest Big Sur. I also tried to set SecureBootModel to Disabled, it still didnt boot. Altough the first line of the error was removed.

[whosdev]

Also, whenever I tried to "merge" the unmodded EFI to the modded one, by placing

PciRoot(0x0)/Pci(0x2,0x0)

        <dict>
            <key>framebuffer-fbmem</key>
            <data>AACQAA==</data>
            <key>framebuffer-stolenmem</key>
            <data>AAAwAQ==</data>
        </dict>

after the add Am I doing something wrong as well?

Place it in the self top level.

Not sure why SecureBootModel is working but I'll look into it.

SecureBoot Disabled worked for me on x1c6 i7 8Gen

¡Hola! No sé si soy tonto, pero hice todos los cambios en el BIOS y todavía no puedo arrancar. Siempre tengo el mismo error. OC: tomó cero system-id para SB, esto no está permitido. Detener en error crítico Con el EFI obsoleto, solía arrancar, pero cada vez que intentaba usar el EFI principal, daba el mismo error. Actualmente usando BIOS 1.53, sin modificar.

Has el intento con la versión de open core 0.6.1 y utiliza el archivo de simple.plist (config.plist) del open core 0.6.1 y verás q te va a funcionar a mi me sirvió y puedes utilizar la guía 0.8.3 para dicha configuración

I have tried disabling the Secure Boot, still don't work, is there anything to do with the Serial Ports?

Unfortunately there is no legacy boot/CSM mode in my PC, so I can't go BIOS boot

I use X1C6 model 20KG and try to disable Secureboot but have same error

OC: grabbed zero system-id for SB, this is not allowed. Halting on Critical error

anyone have an idea?

You need to disable "Securebootmodel" in the OpenCore settings. Yes, you have to do it in BIOS too, but this part here is referencing OpenCore settings.
