No change when I removed DSDT.aml from ACPI/Patched. Replaced it with the one provided above, still the same. I also plugged in a Belkin USB-C ethernet dongle. I don't get the "bouncing", I can set an IP manually but it still does not work. Added in 4 minutes 49 seconds: Without the interface defined, if I plug in the cable, the link remains solid. As soon as I add en0 and apply it, the link status starts cycling between cable is plugged in, self assigned IP, cable is unplugged, repeat. It does the same thing with both ports, and acts similarly with USB ethernet.

Same result, except the computer name changed .. (of course) Send me iMac-Pro.zip

The status will go between: "The Cable for Ethernet is connected but your computer does not have an IP address" or "Either the cable for the Ethernet is not plugged in or the device at the other end is not responding" BIOS settings of "Wake on LAN" either disabled/enabled matter not.

Any suggestions on where to start with why Ethernet goes on / off? ... it was working, I swapped some non-boot drives out, rebooted and it cycles on the ethernet now. It starts cycling once the kext loads. If I boot into some other OS it works.

How did I do video before? ... When it was in Safe Boot, it was like 16 bit color, very pokey, and only supported one monitor. What I have now is at least full color, but still only one monitor. Should be 4K, it's seeing it as half that. Am I able to use either an nVidia 1050 Ti or GTX 650 instead of this tiny old AMD 6570? It's only showing me 1280 x 950. It probably can't do 4K. If I'm reading correctly, the older GTX cards can use some kind of workaround for Mojave?

Just about perfect. I used your 10 20 30 series, put DSDT.aml in patched, added an SMBIOS profile of iMacPro 18,1 ... just the video has weird things going on in places, plus it only shows 7MB of VRAM. When the cursor passes over a button, you see a square behind it, when flipping through the System Preferences window, you'll see areas to the right jumping around next to the window. My second monitor isn't working either, though I suspect that has to do with the video driver in general. Send me Z370R2-iMac.zip

Greetings: I had a 1050-TI but ... CUDA, Mojave ... ahem.. So I put this AMD card in until I get a better one.. It boots in Safe Mode, but will panic with the last thing being @kec.corecrypto Help You helped me on InsanelyMac during a time when the database kept having issues. Thanks for that, too!
