Hey Shiloh,
i appreciate the update on the guide and I tried it out with my setup but I keep getting problems with my Gtx 780 SLI setup
i keep getting black screens. Yosemite is causing much more headaches than Mavericks ever did. Anyway I'm at a point where I'm just gonna give up. I've spent over 40 hours trying to get it to work with everyone's advice here. It would be great if someone could loan you a gt110 card type.
I have the exact same setup as you did but not the 770GTX card.
Unless you have any suggestions I'm at a loss...
Peace
