USB issues with Big Sur after update to 11.4

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.

Hey guys.

Today I upgraded Big Sur from 11.3 to 11.4 and the upgrade went smoothly.

But when I entered the system, the wireless key and mouse could not work, which was caused by the unrecognized USB2.0 port when I checked.

I connected to the system using VNC and found in Hackintool that all the USB2.0 ports were not working,USB3.0 works at 5 Gbps.

I followed the instructions to disable XHCIPortLimit. All ports work, but USB flash drives on USB 3.0 ports only work in 480 Mbps mode.

I tried to customize the ports through Hackintool, but after customization, only USB2.0 will work. I can find many HS ports in Hackintool, but only one SS port. Other USB 3.0 ports do not recognize both 2.0 and 3.0 devices.

How should I solve this problem?

Thank you.
