Casey,
First off; I've been following this guide for years, and I have built 3 Designare systems using it. Thank you so so very much for such an unbelievable body of work. I confess, I stopped reading EVERY post a few thousand ago! But I do search and scour when needed.
My current system (inline with this thread):
SMBIOS iMacPro1,1, iGPU disabled in BIOS, Vega 64 in PCI-1, LG Ultrafine 5k with full functionality (cam/audio/usb), Lilu 1.5.1/WEG 1.4.8, macOS 10.15.7 (19H524).
My hurdle:
I purchased a Sonnet eGfx box and installed a Radeon VII. Now, I understand that without a flashed TR board and what not, there won't be full Thunderbolt support -- I get that. I'm just trying to use it for Resolve -- but on this system, the System Profiler does NOT show drivers installed for the Radeon VII under PCI, and, therefore, Resolve doesn't see it. In Mojave 10.14.6 it didn't work either. I'm writing here because on a much older build (Gigabyte Z170MX Gaming 5, Skylake 6770k running Catalina, iMac17,1 with Alpine Ridge AIC). It DID load the Radeon VII drivers when I plugged in the Sonnet eGfx to the Alpine Ridge AIC.
I'm sure you'll want more specifics, etc., and I'm happy to supply, of course,. But I'm hoping there's something easy off the top of your (or anyone else's head) that would prevent the Radeon VII drivers from loading on this designare build.
Happy to supply any and all info.
Thank you one and all,
J
