MP 1,1-5,1 MSI Radeon RX 560 with Mountain Lion?

[Michael Nova]

Hi, I have my 2009 MAC Pro 5,1 running Mojave with a MSI Radeon RX 560 4gb graphic card

I have a need to temporarily swap my current system drive with my old hard drive that has Mountain Lion OS-X 10.8.5 on it and now can get nothing to display

Is Mountain Lion OS-X 10.8.5 not compatible with MSI Radeon RX 560? Or Is there something I can do to make the Mac see it?

Thanks!

You'll need an older GPU to use Mountain Lion.
