I am running a Mac Pro (mid 2012)


I bought an 8 TB G-raid with Thunderbolt and it doesnt come up on my Mac.


I tried a different cable.


I exchanged the Hard drive and nothing.


I went into the system and it says next to Thunderbolt "No drivers are loaded"


Could this be the problem?


Why wouldnt I have drivers?


Can I get them?


Any help would be greatly appreciated




Mac Pro, Mac OS X (10.7.5), Final Cut X

    There are no Thunderbolt ports on a Mac Pro, so you can't use any Thunderbolt devices.  There are no drivers or adapters that will help.


    The graphics card may have a Mini DisplayPort, which is similar to Thunderbolt, but won't work with Thunderbolt devices or displays.

    Okay so that's a thunderbolt port for a display?


    So am I able to add thunderbolt ports to my Mac?


    What Mac products have thunderbolt ports?


    Thank you for your time.

    It's a Mini DisplayPort.  Mini DisplayPort devices will work with a computer's Thunderbolt port but Thunderbolt devices cannot use a Mini DisplayPort.

    All current Mac computers except the Mac Pro.

    Wow!  I'm pretty stunned and bummed.

    Thanks for your help

    To add external RAID to a Mac Pro you need a PCI-e SATA or RAID card.

    You will not be able to connect that drive to your Mac Pro, there will never be a thunderbolt expansion card.

    So much for that, check first next time.

    Asus's card is a feature card, not an expansion card. It can be used only on that sepcific brand and model logicboard.


    Asus designed that logicboard specifically to have thunderbolt, then removed it.

    That does two things: Cuts costs for those that don't want it, or may not want it right away, and increases profits by making people buy another one of their products.


    Please learn about your source next time, it will save yourself a LOT of embarassment!

    You said:

    there will never be a thunderbolt expansion card.

    But there is, next time be less vague with your sweeping (never hasn't even arrived yet) pronouncements.

  • BitterCreek Level 1 (100 points)

    But there is

    No, there isn't. The Asus board was designed for the card and the card was designed for the board. It is NOT an expansion card, it is a feature card. Specifically, Asus calls it an upgrade card.


    never hasn't even arrived yet

    Actually, by definition, "never" is already here because it will not occur.


    A Thunderbolt PCIe card will never exist because the technology requires  hardware-level access to the PCIe controller, CPU and on-CPU GPU.

    Apple and Intel will not licence TB to somebody that won't provide full-feature compatibility. So a PCI-E card that simply "passes through PCI-E lanes" will never be made.


    Again, please learn about the topic before you chime in, you're just digging your hole even deeper.


    Secondly, Mac Pros do not need thunderbolt. You already have direct access to PCI-E lanes via PCI-E expansion slots, built-in bays for internal drive additions, have built-in RAID support, built in support for more than three monitors AND support for multiple GPU cards.
