Had it installed previously on my Intel system but had a bit of a pain to install on Ryzen system.
Problem for me was that installer would not even boot from USB.
Then I found AMDHS_Installer_v2_clover from here https://drive.google.com/drive/folders/ ... 5Ml7-kkCRp
Just restored to USB via Transmac and tried to boot - it booted to installer.
So I booted back into Windows and created a new partition to install macOS onto.
After installation just had to tweak clover a bit and install Nvidia web drivers.
WiFi and Bluetooth are not working at the moment. I might try to sort that out later, but not a huge deal.
