  • Ultrastudio 4k not showing up or recognized by mac

    Posted by Ben Slama idir on November 19, 2014 at 12:05 pm

    I recently purchased an Ultrastudio 4k. It initially was recognized by my MACPRO
    MACPRO 2013

    Processor 3.5 GHz 6-Core Intel Xeon E5
    Memory 16 GB 1867 MHz DDR3 ECC
    Dual Graphics AMD FirePro D500 3072 Mo
    Software OS X 10.9.5 (13F34)

    It initially worked and I was able to get a live stream into resolve 11.
    Now the system will not recognize the device after update Video Desktop 10.3.
    System preferences / Desktop video (does not see ultra studio 4k).

    I have tried disconnecting all devices and only connecting the Ultrastudio 4k (still nothing).
    I have tried various Thunderbolt ports and cables (still nothing)..

    The weird thing is that System Report see the thunderbolt device…

    Have you found a solution? My US4K is having the exact same issue. I can also get a signal in to the preview screen and out to my studio monitor, but the log and capture canvas is completely black….
