the following kexts are in E/C/k/O
Lilu.kext version 1.4.0
WhateverGreen.kext version 1.3.5
Boot args
agdpmod=pikera. (note, you can go to option in Clover and add it there if you forget, then add it permanently.)
Graphics section in config.plist should have nothing. all blank.
SMBIOS is iMac 17,1 or newer
most issues I have seen are form syntax errors or multiple versions of kexts in different locations
