Cannot Boot macOS with Latest BIOS Despite Disabled Secure Boot

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.

Greetings everyone. I have an MSI Z590-A PRO motherboard that I was using to dual boot macOS Sonoma and Windows 11. After upgrading my BIOS to the latest version, which was necessary for critical CPU management enhancements, I can no longer boot into macOS.

Through troubleshooting, I determined the root cause relates to changes involving Secure Boot. Even when I explicitly disable Secure Boot in the BIOS on this updated firmware, macOS still fails to boot. As further confirmation, I flashed an older BIOS version, did not disable Secure Boot initially, and observed the exact boot failure. However, after disabling Secure Boot with the older BIOS macOS starts up flawlessly.

It seems the revised BIOS enables a variation of Secure Boot that blocks loading macOS, despite my attempts to disable this setting. I would greatly appreciate any guidance getting macOS booting again alongside Windows 11 while retaining the critical updates in the newest BIOS release. I’ve attached both my config.plist file and boot diagnostic logs to better assist. Please let me know if any additional details would help troubleshoot this problem.
