Hi @Shanny,

Hi and welcome.

To answer your question, yes it's absolutely possible! In fact I had just recommended someone the other day such a build:

GitHub - osx86-ijb/MSI-B450-Tomahawk-Max-Ryzen5-3600-macOS: The OpenCore EFI for booting macOS on the MSI B450 Tomahawk Max Motherboard

The OpenCore EFI for booting macOS on the MSI B450 Tomahawk Max Motherboard - osx86-ijb/MSI-B450-Tomahawk-Max-Ryzen5-3600-macOS

github.com

The build should work with your setup off-the-cuff using the Opencore 0.7.8. bootloader. You'll need to place the EFI into the EFI partition of your macOS boot drive or USB installation stick and generate one of the numbers using SSDTPrGen. The full guide to making the installation stick is found here

However you will need to remove whatever boot-arg has been set for the RX5700 on this build which is changing the setting of agdpmod=pikera to agdpmod=ignore for your RX580.
