Hi thanks in advance for any help. See apple s article on using an external graphics processor with your mac that lists supported thunderbolt 3 chassis graphics cards. I have a 2009 mac pro 5 1 and upgrade cpus running os x 10 13 6. The sapphire rx 580 pulse 8gb is the only current generation amd gpu identified correctly in macos.

I wanted to upgrade my video card. Using both aux power ports. These were my results. This is due to it being used in the official external graphics dev kit.
