Hallo again!
I tried now really many video and written tutorials of how to change to Kabylake properties, i used OCLP, Hackintool, lots of advices to change plist and device properties in OCC to patch, i tried on other MacOs, but nothing worked for me.
I also cant boot from usb with iMac 17,1- Smbios ( as proposed in the install-guide) "f) Users with IGPU need change SMBIOS (example: for Skylake Processor change smbios iMacPro1,1 to iMac17,1)" even with -igfxvesa.
Maybe you have some more advice for me?
Thank you, Greetings
