    Hi, I have been using an unflashed nvidia gtx 970 graphics card in my 2010 mac pro. Today, I installed the new security update without thinking and it broke the nvidia drivers that I had installed on the computer. Now the computer won't boot (since it's an unflashed card). I still have the original AMD card that came with the computer, but the drivers on the computer are still set to nvidia so the AMD card won't boot either. Does anyone have a way to fix this? I would be eternally grateful!

    The drivers on the computer are not still set to nvidia. That's precisely what this update breaks. If you were able to boot up, you'd see a dialog box waiting for you that says the nvidia web driver has been disabled and the computer is now using the OS X default driver.

    If it were set to nvidia still, you'd be able to boot up with the 970.
