Big Sur Opencore booting from USB and not working from SSD EFI

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

Hi

I have a working version of Big Sur installed on a fresh SSD, AMD Fx system (990fxa-UD5, fx8350 processor, AMD580x graphics).

Booting from my OpenCore USB stick works perfectly. I copied the content of my USB to the SSD EFI partition. So I would expect this would work, like it always did in the past with all previous MacOS versions. Not this time. When I select the Big Sur in the boot picker, I get an immediate kernel panic.

I included the OpenCore log for the 'Working USB' and the 'Not working SSD' EFI. Again, it's an exact copy, so I do not get why this does not boot.

Has anyone seen this before?

Thanks!

Hi MaLd0n, what do you mean with 'same folder'?

Yes indeed, I did an exact copy from the USB Efi folder to my SSD.
