How to flash a RX6600XT RX6800XT RX6900XT for Mac Pro 5,1



Hi Folks, So I just flashed a RX6600XT and it works! You must be running Opencore and Monterey 12.2.1 or later
Links below for all you need. It must be done in a PC Tower or A Mac Pro 7,1 running Windows.
DO THIS AT YOUR OWN RISK! But quite a few folks have done it with Success. You will need the Pixlas Mod or an external PSU if you want to go with a RX6800XT or RX6900XT.
