EVGA GeForce GTX 750ti stopped working with latest OSX 10.11.6 (15G21013)

I'm using a Mac Pro (early 2009) OSX 10.11.6 (15G21013) with a GeForce GTX 750ti. I know everything is still working with Windows through bootcamp so all hardware is functioning nominally.

When is an update expected to allow my graphics card to start working again? In the past when an OS X prevents my graphics card from working it would start working again once Nvidia released a companion driver update for the OS X update. In this case their customer support is claiming everything is updated and I've got the most current drivers installed.

Is this going to turn into the blame game? Nvidia blames Apple and Apple blames Nvidia?

Updating to the next OS X or updating my computer are not options.

I need a OS X or driver solution. It's currently preventing work and my graphics card is currently only useful as a crappy door stop.

Thank you for your help.
