Not working

  • WiFi: Intel 3168 NGW

Pre-Installation

 

I will not go through the basics since it is explained in details here on this site. Briefly, the process is to:

  • Get Clover
  • Get Catalina macOS installer
  • Create USB with 2 MBR partitions (FAT32 for Clover and HFS+J for the installer)

 

 

Required kexts

 

 

Config.plist

I used the one provided by RehabMan called config_HD615_620_630_640_650.plist. Download it from GitHub. It has almost everything you will need with only few edits for audio.

Edits:

  • [CPU] Make sure there is lilcpu=9 setting in boot arguments needed for Kaby Lake R CPU to be recognised correctly.
  • [GPU] Make sure there is a patch GFX0 to IGPU under ACPI->DSDT
  • [GPU] Under Devices->Properties->PciRoot(0)/Pci(0x02,0) make sure that the AAPL,ig-platform-id value is 00001B59, and the device-id value is 16590000
  • [AUDIO] Under Devices->Properties->PciRoot(0)/Pci(0x1f,3) set the layout-id to 40 and the device-id to 70A10000
  • [SMBIOS] Set Mac model ID is iMac19,2

Notes

  • For some reason with latest version of Clover the install partition was not visible. If you run into the same issue you can downgrade Clover to r5103, which worked perfectly.
  • WiFi / BT Intel 3168 NGW needs to be replaced if one needs WiFi.
  • Someone mentioned that to get HDMI work properly you may need to change AAPL,ig-platform-id value to 00001659 for PciRoot(0)/Pci(0x02,0) - not my case but may be considered if you get this issue.
  • Don't forget to generate your serial and other SMBUS values before signing in with iCloud services.
