Hackintosh-ROG-STRIX-Z490I

This repository is about hackintosh on Asus ROG STRIX Z490I. For now, all the hardware is working as expected, it’s ready for daily usage and I will continue to follow the updates of OpenCore and macOS.

Anyone who has the same board can use my EFI directly. The source EFI folder uses debug version of OpenCore, mainly used for installation and testing. It’s recommended to use the release version for daily usage, you can replace it yourself or just download my release. Either way, don’t forget to edit the EFI/OC/config.plist file, you should generate your own SMBIOS info by following the Comet Lake Config Guide #PlatformInfo.

Highly recommended reading the whole OpenCore Install Guide before you start.

HDMI/DP display and audio output are working fine.

Wi-Fi/BT

Working by using an m.2 M-Key adapter with Apple Airport Card BCM94360CS. It’s natively supported, airdrop, handoff, and sidecar are working perfectly. The bottom side m.2 slot for SSD is occupied and the bottom SSD heat sink must be abandoned.

The Bluetooth can not be recognized by default, it uses the onboard 9-pin USB2.0 port for power supply, so USB mapping should be fixed to make it work.

The onboard wireless network card Intel AX201NGW uses m.2 E-Key slot and CNVi protocol. I tried to replace it with an m.2 A-Key BCM94352Z card, the slot is compatible but it didn’t work even in Windows, thanks to the CNVi thing ?. So don’t try to replace the onboard card.

USB

All ports are working fine except for the ones disabled due to the 15 port limit.

USB Ports:

All ports: HS01 ~ HS14, SS01 ~ SS10, USR1 ~ USR2

HS02: AURA LED Controller / HS14: Onboard bluetooth

You can make your own mapping by hackintool, here’s my choice:

Sleep/Wake

Works with DP output and power button. GPRW Patch is used to disabling the USB device instant wake.

Note:

1. Bluetooth has a delay of about 7 seconds after the display is turned on.
2. When using HDMI, the display cannot be woken up.
3. Without enabling GPRW, a keyboard press or mouse click can wake up the display as well, but a second press or click is needed when the light is on, I tried to fix it by following Keyboard Wake Issues Guide, but didn’t work. So my choice is to just use the power button, disable SSDT-GPRW if you want to use a keyboard or mouse to wake up.
