Struggling with ASUS PRIME Z490-P - USB stops working randomly despite proper USB map

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.

Once I set it up around 2020, it worked perfectly. Then I wasn't using this PC for a while and upgraded to Sonoma, which revealed some issues I describe in detail on another forum. I already sorted out USB mapping and even got some custom-patched DSDT solving the [code]ACPI Error: \_SB_.PCI0.XHC_.RHUB.HS13 Namespace lookup failure, AE_NOT_FOUND[/code] error I couldn't solve on my own, but the main issue with this mobo still persists.

The problem is that right after boot, the USB keyboard stops working. To make it work again, I have to either unplug it and plug it in again or put the system to sleep and wake it up. Then when using the system, the keyboard occasionally stops working. The only 100% way to reproduce it is to go to system updates (!) - then in 100/100 cases the USB will stop working. Yeah, I know how bizarre it is!

It only affects the keyboard; other USB devices remain unaffected. Anticipating the question: I did try a fresh install and confirmed that the keyboard itself is fine since it works well under Windows/Linux.
