Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Hi everyone,

Can anybody write a mini guide, or, if there is one already, to post here a link of it.

HOW TO SPOOF OR HOW TO FAKE CPUID FOR OPENCORE. ?

I know where you can put it in the OpenCore Configurator but have no idea how to make one.

Like example for i5-11600K OR i7-11700K, which I want to buy.



@CaseySJ :​

Maybe if you have the time to explain us who have less knowledge, how to do that s.v.p.
If you are installing Big Sur, the Fake CPU ID is already present:

Just about to test this - It renamed the EFI partition of my SanDisk Flash drive. Is that supposed to happen? It is now called "EFI-USB-908"
Yes that's correct. It's a very good feature because too many applications cannot differentiate between multiple "EFI" partitions if we mount two or more at the same time.

Thanks for the fast reply. So the CPU ID does not matter which CPU I have, i5-11600K or i7-11700K?

I ask because I see on some i9-11900K EFI folders on the Internet that almost all of them have different numbers there at OpenCore Configurator where you highlighted here above.

We're currently using CPU ID 0806EB, which belongs to the mobile Intel i5-8265U. This is less than ideal. We can, however, go to this website and try different CPU IDs.

Because macOS recognizes the i7-9700K, we can also try 0906EC, but it needs to be entered in reverse byte order: EC060900

The website allows you to select any Intel CPU up to 9th gen. Other sites should have 10th gen CPU IDs.

Excellent. That’s a great feature! The app works excellently!

@Inqnuam devoted a lot of time and effort (and coffee) to create this app! :)

By the way, the latest WhateverGreen has this new feature to disable any specific GPU:

Haha! Typical. After all this time, I finally understand the process and make an SSDT, only for it to not be needed :lol:
 
** OpenCore 0.6.8 EFI for Z490 Vision D **
Supports both Catalina and Big Sur
Just wanted to point out that the current OpenCore Configurator 2.33.1.0 does not play nice with the new EFI provided by @CaseySJ . I get the following error upon rebooting: OCTY: Failed to locate apple event protocol - Not Found Halting on critical error.

I found on line 976 that OpenCore Configurator was changing the line from <string>Builtin</string> to <string>OEM</string>. Once changing the file back to <string>Builtin</string> everything works correctly...

Gluck!

If you unmount the EFI partition HackinDROM rename it back to "EFI" automatically :)

Thank you so much.
