When I try to install AMD software it says it cannot find any AMD hardware installed. I have a new 20.1" iMac. I followed the instructions on the Apple Support page, that simply does not work.
iMac Line (2012 and Later)
Do you see the AMD GPU in the Windows Device Manager?
Did you use BC Assistant to install W10?
BTW you have to download boot cam version, you cannot use standard one.
