Asus ROG STRIX H370-I GAMING Hackintosh Guide

October 2020 switch to OpenCore

The old version of this guide, using Clover and CorpNewt’s Hackintosh Vanilla Desktop Guide can be found here. I had started to get regular graphics (I think) – related lock-ups (i.e. black screen/force shutdown) with the Clover-based install, and updating Clover and kexts had become complicated. So far there have been no lock-ups with OpenCore.

OpenCore guide

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

ACPI

I ran SSDTTime in Windows with the following options:

• Dump DSDT
• FakeEC
• PluginType
• PMC
• AWAC

Then added:

• SSDT-USBX.aml

PlatformInfo

I’m using an iMac19,1 SMBIOS

USB 15 port limit

• although the cleaner method is probably to generate a USBMap.kext with USBMap, I’m still using USBInjectAll.kext, XHCI-unsupported.kext and SSDT-UIAC.aml generated previously
• this graphic might still be useful when deciding which ports to include or exlude: 
• example SSDT-UIAC.dsl with unused/excluded ports commented out

Audio

• my layout id is 7, so I have this in DeviceProperies:

<key>PciRoot(0x0)/Pci(0x1F,0x3)</key>
<dict>
	<key>layout-id</key>
	<data>BwAAAA==</data>
</dict>

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

OpenCore GUI

• this isn’t working at the moment and I’m not sure why

• updating to OpenCore 0.6.3 (with the necessary driver, kext and config.plist updates) has fixed this so the GUI is now working.

Windows 10

• wake from sleep in Windows 10 is broken since the move to OpenCore
