I am also at same problem . No luck with this

Both clover and open loader making the same problen.

Update: 

Set iMacPro19,2 in config.plist 
and prev-lang:kbd => en:US:0

Then reset nvram from opencore if still not work.

After that, everything is working flawlessly with gpu also.spacer.png

Did this, to no avail. Still grey screen after verbose. Also, where should I edit the iMacPro19,2, is it in the General? Thanks
