I have used, or should I say tried to use OpenCore, but even reading everything and trying to follow all of the instructions I get most of it, but still needed help. Someone here (many pages back, about 6 or 7 months ago), had an EFI file that was done in OpenCore for the very Asus X299 Prime-DELUXE (v.1 not v.II) mobo and just tired it and it worked like a charm! I was even able to upgrade several times with the same EFI file with no issues so far. I'm grateful things are working!
In any case, (from this WEG file you're talking about), I would need to go into my existing EFI > OC > Kexts > WhateverGreen.kext and delete it, correct? If I removed it now, that wouldn't affect anything with the existing Radeon VII cards I'm using would it? Thanks again for your help.
