- MSI MPG Z490 Gaming Edge Wi-Fi
- Audio: Realtek ALC1200-VD1
- LAN: Realtek RTL8125B 2.5G
- Wireless Card & Bluetooth: Intel AX201
- 4x8GB (32GB) Corsair Vengeance RGB 3200Mhz CL16
- PowerColor Red Devil Radeon RX 5700 XT
What’s tested and working?
- Wi-Fi & Bluetooth
- Wi-Fi works with the itlwm.kext found here1 but read into this a bit more; it requires you to hardcode the SSID and password OR use HeliPort to gain Wi-Fi access.
- I did NOT test AirportItlwm.kext.
- Bluetooth works with the included kexts.
- The kext for our LAN adapter does not auto-negotiate and thus needs to be manually set to 1000baseT.
- Some ports are disabled due to macOS’s 15 port limit; this is explained further down.
- Native CPU power management
- Sleep/Wake, Restart, Shutdown
1: I have not included the itlwm.kext in this EFI setup as I don’t need it.
Issues Encountered During Installation & Setup
- You can’t install macOS without a network connection, so you have to use the terminal to set the negotiation speed.
ifconfig en0 media 1000baseT should typically take care of this.
- I had this nagging issue where the installer would crash back to the start screen after I select a disk. I found this issue by looking in the installer log and found the line
No mapping for user data read which, upon some Googling, revealed USB and port issues. Unfortuantely I didn’t have macOS installed so I wasn’t sure how to fix this…so I disabled all but two ports in the BIOS and found out which ports were still enabled by trial and error. I used a USB Hub for my installation media, keyboard and mouse and it installed without a hitch.
- My current issue is that the system will essentially crash (speaker starts making a buzzing noise, cursor turns pixelated and the system stops responding.) Some Googling shows that this might be due to my overclocked RAM. I didn’t think this at first because my original overclock was stable on Windows, but it figures that it’d be different on a Hackintosh (I mean, duh, right?) Currently have it toned down a notch and testing.
- I pretty much followed the Dortania Guide to a tee
- Using USBMap, I disabled ports I deemed non-essential to my needs – which were my front USB ports.

I tried LLC mode 2 but saw peaks of 92 celsius and an average of about 89-90 celsius. It was much more stable temperature-wise on LLC mode 4.
