    Hi All,

    I recently installed an unflashed GTX 1060 3GB in my Mac Pro 5.1 running OS X 10.12.6, and found that after I restarted, the other PCI slots are all disabled, and I see the message “there was an error while gathering pci device information” in System Profiler. Before installing the card, I installed the NVIDIA and CUDA drivers, and the new GPU seems to be working really well otherwise.

    I normally boot the system off a Sonnet Tempo Pro Plus that has 2 raided SSDs, but so far I'm unable to access these drives with the GTX 1060 installed.

    Is there a way to fix this, so that I can continue using the other PCI slots? Do I need to have the card flashed?

    Thanks,
    Alex

    Would guess that you attempted to install an update, or an update was automatically installed. Enable SIP and/or put an EFI card in and see if that "fixes" the update issue. Once those updates complete, everything SHOULD (hopefully) go back to normal.

    This is completely normal for 10.12.6, not a prove for anything is disabled.

    Thank you for your responses! I switched in my ATI Radeon 5770, which got the PCI slots working again. Then disabled SIP, which might've been the culprit here. Then re-installed the NVIDIA and CUDA firmware, and now with the GTX 1060 back in the system, it looks like it's working.

    Even though the system profiler shows that error message, "there was an error while gathering pci device information," it seems that all my other PCI cards are functioning just fine.

    Thanks again for your help!

    just to clarify for anyone else with this issue...
    with SIP - did you DISABLE or ENABLE?
    still on OS 10.12 (build number?) or have you upgraded to OS 10.13?
    what NVIDIA driver versions are you using?

    Ah, sorry, I got that backwards up above.
    I enabled SIP (it was disabled before)
    I'm running OS X 10.12.6 (16G29)
    NVIDIA Driver 378.05.05.25f01
    CUDA Driver 9.0.197
