Hi again. is some one who find right solution to active Z390 + 9900K + HD630 + AMD RADEON + SMBIOS 19.1 + 10.14.5 ?
I try many option but no luck when I try to active HD630 GPU not work very stable.. a lot of lagging.
I upload my last config.
WHY you not buy any EVGA GTX 680 and them FLASH bios to recognise like original MAC edition.
after that no need enything no driver no patch.. and trust me on this MAC PRO 3.1 ( I have same ) you not see any different between 970 and 680;)
I use special version of 14.4.4 System Version: macOS 10.14.4 (18E2034)
I'm using 9900K + RX580, So without HD630 system It's not very powerful on FinalCutPro.
I waiting 14.5 to try disable HD630 from bios and then I should find solution for fake CPU. System should see 9900FK not 9900K...
I have absolutely same problem. Right now I'm testing i5-2500K with RX560 - 4GB. There is no IGPU .
HEVC are perfect but on H264 are green glitches/artefacts in the output after about one second of play. after that on all film there is no problem. I use SMBIOS 14.2, also I test SMBIOS Imac...
