This site might be helpful in answering your question: Radeon Software Adrenalin Edition for Windows Not Compatible with Boot Camp? | tonymacx86.com.
Edit: I mentioned the link above because it concerns a MAC User asking about installing Windows Adrenalin Driver in a MAC OS Computer that is not using Windows in a BOOTCAMP environment. According to the thread, The Windows AMD Driver seemed to be working with the MAC OS environment.
Add to this when will AMD's team in a timely manner port to MacOS "AMD Radeon Pro Adrenalin, AMD Radeon Enterprise Adrenalin and not just AMD Radeon Adrenalin"? The only AMD software that was until recently ported to MacOS is Radeon Pro Render. Which if I recall correctly was released to Windows and Linux customers over a year ago. It's nice to see AMD Link in the iOS App Store but it's useless to Apple customers unless they run Windows through Bootcamp or switch out from the Apple MacBook and iMac line just to have it connect with AMD Radeon Adrenalin. The delay with AMD providing MacOS software support to work with their GPU is frustrating not just from the premium cost of these cards compared to NVIDIA but also as it creates an inconsistent customer experience compared to the full support offered by AMD for Windows and Linux users
