I have a mac pro 1,1, the first intel model, and I have it running el capitan, with 16GB of RAM & the OS running off of a SSD. I bought this card, being told it would work in my mac pro, and it "works". I only get one of the video ports to display, and every movement of the mouse, let alone the windows makes the screen all choppy, and redraw itself a bunch of times.
I've seen screenshots in old posts in forums that are closed saying it works, but I can't find any drivers or anything.
I will HAPPILY provide any information you need to help me with this.
PLEASE help me!
Thank you a million times in advance!!!
