Confused right direction?

Thanks, I've got it all running now and I've learned a bit. (working in Shell64, editing, do know I've edited manually the framebuffer settings but don't know in what format they are and how to convert them to understandable values.)

The thing I now encounter is massive flickering and strange display updating. I'll try to fix this. See attached for my configuration as is boots. (19.1 )

Thanks lovely community and contributors, you make it very pleasant being here!

If you are using IGPU only, I suggest you switch to iMac18,1 or MacMini8,1 system definition.

I'll take your advise. What is the best when I switch to a PCIe GPU?

When you get a video card, you can use iMac18,3 or iMac19,1 or iMacPro1,1 (if you disable IGPU).
