    I have an early 2009 Mac Pro (MacPro 4,1), which came with an NVIDIA GeForce GT 120 graphics card. So that I could run new CUDA software, which requires an NVIDIA GPU that has "compute capability" of 2.0 or higher, I bought a new graphics card off of ebay. My new card is an NVIDIA GeForce 470 for Apple Mac Pro, 1280 Megs Femi CUDA. However, my system doesn't seem to recognize the card.

    I just updated to OS 10.7.5, I made sure the card power cables are plugged in, and I see that the card fan is running. But, no output. With just the new card installed, my display stays black and says "no input signal detected". With both new and old cards installed (and display running from the old card), my System Report doesn't report that the new card is installed.

    Does anyone have any ideas? Do you think the card is faulty, or is my system not set up properly somehow?

    Thank you!

    Do you have another machine to put the card in? A non-Mac? I could be a faulty card.

    Also try to contact the seller about the problem and if you could return the card. Best to buy from sellers with adept experience in flashing cards and offers returns.

    Sounds like faulty card. Even with compatibilty problem with mac, it should be detected as PCIe device.

    Thanks for all the helpful replies! I'm going to try to return the card and get one that I know works.

    Assuming this is a hacked card. There never was an official GeForce 470 for Mac.
