srmusico Posted September 16, 2017 Share Posted September 16, 2017 Hello Guys I have a new 200 series board with an i5 7400 and 8 GB Ram + Gigabyte Nvidia Geforce 710 The system definition that I used is 17,1 because I have read that for kabylake is the best choice working on Sierra 12.6 Everything was working without the GPU plugged. When I plug the Graphic Card, I need to change the SMBIOS to iMac 14,1 because with 17,1 I get a black screen at boot time and the monitor disconnect. (The computer stills on and in password screen, but without image ) With 14,1 iMac SMBIOS everything is working and recognized. I have read that is a problem that could be fix with "AGDPfix.v1.3.zip" But ,is there any danger in the stability if I have 14,1? what is the better option? Thanks for your help!

Hi there, It's better to use iMac 18,1 or iMac18,2 SMBIOS for KabyLake processors, you will have better power management for you CPU. macOS Sierra 10.12.6 has native support for KabyLake and if you use iMac18,2 it will suite your hardware resources better. to avoid the black screen you can use this patch under "Kext and Kernel Patches": Name: com.apple.driver.AppleGraphicsDevicePolicy Find: ba050000 00 Replace: ba000000 00 Comment: Disable board-id check to prevent no signal © lvs1974, Pike R.
