    I use Audirvana on my macbook, this app has his own dac recognition and can play 24 bits files, I never have issues streaming to my dac, I also have a cheap hand held dac that I use for my headphones that is also recognized by the software.
    Streaming music from macbook via usb, to a musical fidelity V90 dac, to a Nobsound ns-01P tube pre amp with jj ecc803s gold pin to poweramp arcam Alpha 8 power amp to Q Acoustics 3050 floor standers.
    Favourite music progressive rock.

    I also had some terrible problems recently.

    I use a late 2012 Mac Mini with Audirvana feeding a Heed DAC via USB. The sound output just stopped without warning. Everything 'looked' OK, just no sound! It was driving me absolutely bonkers.

    So, to cut to the chase, I wiped the Mac clean - erased the HDD - and reinstalled the OS, which in my case was El Capitan. Result, is that now everything works perfectly and normality is restored.

    I suggest that the OP tries the wipe clean option. As a lifelong MS Windows user, I was pleasantly surprised at how painless it all was. Might be some future for 'the fruits PC' after all!

    It is obviously not connecting to the Mac if there are no lights on the DAC. Tried a different cable? I'm sorry, don't know Macs, but may be the program settings?

    USB ports are pretty stable. Is this your only DAC? Or are you swapping it out for another one?

    What options do you get when you haven't got the DAC connected?

    If a complete HDD wipe and OS install seems a bit too nuclear then have another look at settings. Go to System Preferences and select Sound, then make sure that your DAC is selected and not the internal speakers. Then go and find Audio Midi, which is in Utilities I think, and make sure that, again, your DAC is selected there and is set as default. Often I found that although the sound prefs are OK the Audio Midi mighty not be. In all those areas make sure that the volume is turned to max and mute is not selected.
    You can also try a PRAM reset -you restart and hold down some keyboard buttons which I can't recall right now (it's on Google), and a reset of SCM, which you do by unplugging the power for some minutes.
    After that you need to identify if your components are working properly. First thing to try is another source, so maybe try another computer. Remember if you can only get hold of a PC you'll probably need DAC drivers. Oh, and the usual thing of trying a different USB cable.
    The thing that really did my nut with my issue was that everything seemed to work and 'looked' like it was working but there was no sound. It took the reinstall to sort it out.

    Good luck...... and yes, this is precisely why vinyl is better

    If I unplug the Dac by pulling out the usb lead then push it back in againg all the lights flash for about 1 second

    How do you select USB input on the DAC?
