IOKit daemon stall (60s) "pxsx" during startup on Tahoe

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.

Used a slim EFI, successfully booted into the system and installed macOS. However, when I added the extra kexts back, the startup speed became significantly slower, looping error message "IOKit Daemon (kernelmanagerd) stall[0], (60s): 'PXSX' ", but eventually it would boot. Also, my wifi is not working, while Bluetooth is totally fine. I'm using a BCM94352z wireless card with BlueToolFixup.kext, BrcmFirmwareData.kext and BrcmPatchRAM3.kext, which seems to be the problem. I saw this post here,

however, the link provided in the answer that solved the problem isn't available any more. My full EFI is included here: https://drive.google.com/file/d/1Hxns_bCOCakwLRuYf2NnlAAbquQKF3vb/view?usp=sharing. Help is very appreciated!!!

Update all kexts to last version

Thanks a lot! I updated all kexts and disabled the AirPortBrcm4360_Injector.kext plugin, and finally got the system to boot very fast! However, while the wifi icon doesn't show the exclamation mark now, it still can't discover local networks, nor can it receive Airdrop. Is this a problem with macOS26? Would I need to do other patching, like the AppleALC kext?
