I currently am trying to connect a MacBook Pro Retina (2012) to a Topping D30 DAC via USB. I've had issues with USB audio ever since Apple release El Capitan. I'm currently running Mojave 10.14.3. My Mac won't recognize the DAC (it's not listed in system information or MIDI or as an audio output option in sound preferences). I've tried numerous cords (including ones that I know have worked in the past). I've tried both USB ports. I've tried rebooting with it connected and powered "on." I've tried rebooting with it connected and powered "off." I've tried rebooting with the DAC disconnected and reconnecting the DAC when it's already powered "on." I've tried rebooting with the DAC disconnected and reconnecting the DAC when it's powered "off" and then powering it "on." I've reset SMC (once with the DAC connected and once with it disconnected). I've reset PRAM/NVRAM (once with the DAC connected and once with it disconnected). Nothing. I've tried a few other tricks in terminal and still... nothing. It was randomly recognized last week for an evening but nothing since. I'm at a complete and total loss of where to go from here. I'm about to install windows and run it in parallels. Does anyone have any other ideas for me?
