I had been sucessfully runing a Sapphire HD 7950 video card on a Mac Pro 5,1 (2011) 16GB and MAC OS X 10.9.1. After Upgrading to OS X 10.9.2, the video card would not boot. I had revert to my old video card to make it operatonal, but prefer to use the 7950.
Have others experienced this? Has anyone found a sucessful solution?
I am very interested in getting my 7950 running again. Thanks.
