    Yeah, the 10.6.8 driver is working fine for me with 10.7 Lion

    I think that's your problem. Download the 10.6.8 driver from NVIDIA's website and also the 4.0.21 CUDA driver and you should be good.

    hmmm, my machine isn't booting any longer. I just see two grey screens with a rotating circle on one of them...

    Is the Quadro 4000 the only graphics card in your machine? Do you still have the original graphics card?


    My Mac Pro came with the Radeon 5770 and I replaced it with the 4000. I ran both cards together at first but I didn't notice any difference in rendering speeds, so I took the 5770 out.


    If you still have your original card you could try rebooting with it and loading the NVIDIA driver for the 4000, then put the 4000 back in and reboot. According to NVIDIA's website you're supposed to install the drivers for the 4000 before putting the card in, so maybe this is the problem.

    back again...

    I sold the original AMD card :-(

    I installed Lion from a USB CF-Reader and migrated from my iMac so everything is up and running again...


    Currently my MP is running Lion with the original drivers that are crappy but... I hope that either Apple or nvidia comes with a new driver.

    From the nvidia support came an answer that if I had installed old drivers I should remove them and work with the built-in drivers from Lion - weren't they listening? I told them, that the drivers are sh.. and they tell me to use them as the only solution - ***!?


    Thank you anyway ljpiii1!

    Sorry I couldn't help you more.



    Hopefully NVIDIA updates their driver for Lion.


    It still puzzles me though because I am not experiencing any problems with my Mac Pro / Quadro 4000 combination at all.

    Did you try installing the drivers using root user?
