EFI AMD 5700XT for Mac Pro 4,1/5,1
Another fine addition for your 4,1/5,1 Mac Pro. YOU MUST RUN 10.15.1 OR LATER FOR FULL FUNCTION ! The EFI will allow you to boot into older OSs with a single display to navigate and get some minor work done. You will want to install Catalina before the card comes. Note also that we are offering a limited number for Pre-Release sales. Cards will begin shipping by March 15.
Unlike the Vega56/64, there are NEVER power issues with these. A good way to transition into newer OSs and prepare for 7,1 Mac Pro. They should also function normally on a 7,1 when you make the jump.
For use in 10.15.5 and 10.15.6 requires the use of a component of 10.15.4
