MacPro Early 2009 Install Flashed Nvidia GTX 570

[cdarlington1]

HI

I have a MacPro Early 2009 with a os x flashed Nvidia GTX 570. I'm running latest version of Yosemite. Just want to confirm if possible that I can install this card with Yosemite and it'll work. I realize I may need to download some drivers but i'm not that interested if it's going to be a major hassle to get it to work (modifying text docs,etc...). Anyone have any thoughts?

Just use the Apple drivers. Use Safe Boot if you get into trouble as it loads limited (Apple) set of extensions.

As the guy who adapted the EFI on your card, I can say it should "just work."

If it has multiple ports, only 2 of them will function.

But you shouldn't need to do any driver fiddling unless some 3rd party messed up the rom.
