Gigabyte Z390 M Gaming build with working NVRAM

[fFour]

Try ig-platform-id = 00001219

I tried putting it in Device Properties and also under Graphics section (separately, and then also both) as seen in pics but same results. Also attached hackintool screenshots, I noticed I can’t seem to get the ??? to go away under Intel Generation.

iMac17,1 is not correct for your hardware

Is there a recommended choice that might work for me on High Sierra? I’ve tried a lot of them but haven’t tried others with the platform id chef mentioned.

Edit: Let me add my 5700 is pulled (using iGPU) in case that was the problem you saw

Thanks, should I still try to use chef’s recommended ig-platform-id = 00001219 or switch to another? And which is better, in Device Properties or Graphics section?

Try these settings.

Don't use config.plist > Graphics. Leave that section blank.

Only use config.plist > Devices > Properties.

device-id = 12190000

Add boot argument "-disablegfxfirmware" (without the quotes)
