Interesting, Any guide on how to get both internal and external graphics working together? Have this with HS and works very well, I had issues when updating to Mojave.SMBIOS'es 18.3 and 18.2 expect that the device has two graphic cards, internal and external, that's why there is flicker when you use only internal Intel card. 18.1 is your friend, since it is from a iMac without external card.
No problem, Just didn't realize that maybe I should try 18.2 or 18.3 being that I have both internal and External being utilized. Though on occasion I do get a graphics error that forces a reboot. We change our bios to use both Internal and External graphics. It has helped some people who were having slow Bruce tests in FCP, and processing HVEC encodings. For me it fixed an issue I had with Photos processing video uploaded from a DSLR. Just was looking for addition info.What's the problem with that? I'm just saying that when you have only internal CPU graphic card (which is visible on the screenshot) and set SMBIOS from an iMac that has both - it flickers like hell. Had the same problem. Solution to that is to set SMBIOS of the machine that doesn't have external GPU when you don't have one. That's SMBIOS 18.1
Just gave it a try, but no luck with iMac 18,1: not starting, like iMac 17,1. I'll stick to 14,2.SMBIOS'es 18.3 and 18.2 expect that the device has two graphic cards, internal and external, that's why there is flicker when you use only internal Intel card. 18.1 is your friend, since it is from a iMac without external card.
