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

AppleALC.kext Lilu.kext RealtekRTL8111.kext VirtualSMC.kext WhateverGreen.kext



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.
