Asus ROG STRIX H370-I GAMING Hackintosh Guide

December 2021 update

The PowerColor Radeon RX 5700 XT 8 GB Red Dragon was causing too many system lockups (seems to be related to using dual monitors) so I'm back to the Intel UHD Graphics 630. At the same time I updated to OpenCore 0.7.5 in preparation for Monterey.

My system

• CPU: Intel Core i7-8700K
• CPU cooler: Noctua NH-L9i chromax.black
• Motherboard: Asus ROG Strix H370-I Gaming
• Memory: Corsair Vengeance LPX 16 GB (2 x 8 GB) DDR4-3200
• Storage: 2 x Samsung 970 Evo Plus 500 GB M.2-2280 NVME Solid State Drive
• Graphics: Intel UHD Graphics 630
• Case: DAN Cases A4-SFXv4.1
• Power supply: Corsair SF 600W 80+ Platinum

OpenCore guide

I followed the Dortania guide step-by-step; as I'm new to OpenCore I'll only add a few comments.

PlatformInfo

I'm using an iMac19,1 SMBIOS

Kexts, drivers etc

USB 15 port limit

• I generated a USBMap.kext

Audio

• the audio layout id is 7; the preferred method now seems to be to use alcid in boot-args, so I have alcid=7

Issues

RTC/CMOS error

• on restart I was getting the BIOS error The system has posted in safe mode. This is fxed with DisableRtcChecksum in Kernal -> Quirks set to true:

<key>DisableRtcChecksum</key>
<true/>

Intel UHD Graphics 630 and dual monitors

• my primary monitor is on the Display Port and secondary is on HDMI
• I have the following in DeviceProperties to get dual monitor working, but I still have to power-cycle the second monitor after booting or waking from sleep:
