Enabling AHCI on Gigabyte Z690 UD AX DDR4

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 cannot find a way to enable AHCI on my Gigabyte Z690 UD AX DDR4. The bios does show the SATA drive on which Sonoma is installed for this card and cpu; I can also see the usb installation drive in the bios but when I boot with F12 I end up on the Bios window. By the way I updated to the latest Bios version F28. I'm certainly missing a particuler bios setting.

When I enable CSM I can see my drives in the boot menu but they are not displayed as UEFI even though they are. With CSM disabled the UEFI drives just don't show up.

How do you enable AHCI on my motherboard?

Thanks

AHCI is default setting on this chipset.

Thanks for your reply. Then why can I not see any SATA UEFI drive or usb install EFI drive?

Can you take a look at my configurations?
