  • Notes:
  • Troubleshooting iGPU with full acceleration

I followed the Dortania’s guide to the letter, then checked the USB I made by that guide. Everything went great except when it reaches the recovery setup ‘language choice’ screen, the screen goes black. I found that the SMBIOS is the problem. iMac18,1 caused me troubles.

I changed that to MacPro6,1 and the setup goes very smooth.

In OpenCore config.plist, in DeviceProperties section, I added this:

PciRoot(0x0)/Pci(0x2,0x0) layout-id Data <00001259> 
  • Fixing the ethernet connection

After finishing installing Big Sur 11.2.2, I found that I don’t have internet connection. After trying the other port, the internet is on. The motherboard has two ports, only one port works. The one that is beside the USB-C is not working. The kext IntelMausi.kext is used for the ethernet connection Intel Ethernet I219-V.

  • Fixing sound:
  • By following the guide of fixing sound, I got sound. I use the green aux output, and I choose Internal Speaker as my output device in Sound Preferences.
  • In OpenCore config.plist, in DeviceProperties section, I added this:

PciRoot(0x0)/Pci(0x1F,0x3) layout-id Data <21> 
  • Wifi and Bluetooth:

I only needed to add three kexts files in the Kexts folder.

AirportItlwm.kext, IntelBluetoothFirmware.kext and IntelBluetoothInjector.kext

  • Sidenote: Ubuntu grub menu

When I put the driver file CrScreenshotDxe.efi in Drivers folder of OpenCore to screenshots of the OS picker, keyboard keys are disabled at the grub menu of Ubuntu. I removed the file and got the grub menu working normally.

  • USB Mapping

I used Hackintool to map my USB ports. Then added SSDT-EC-USBX.aml and SSDT-UIAC.aml in ACPI folder. Also USBPorts.kext.

boot args:

keepsyms=1 debug=0x100 alcid=21 

Final thought:

This is not my first hackintosh, but it could be the best. If anyone here can help to fix sleep and chime sound of OC picker, I’ll be thankful.
