You'll have to either use the Chrome browser for "hifi" quality or the Tidal app for Mac with AIR. There is no AirPlay, miracast, or Bluetooth audio capability with Devialet. With the Devialet expert remote program for iOS you can play content that's physically on the I-device. But few of us store music on our I-devices.
Honestly most Devialet we sell is with a third party streamer such as Auralic Aries or Aurender. These are more stable, easier to use, and sound better than Spark. Hopefully eventually Spark will be improved in the future (particularly for the software). But for now even the $549 Aries Mini is a better option. I'd hook it up to Expert via the USB connection. Even if your using Phantom I'd still hook up an Aries or similar (eg Bluesound or Sonos) over optical to the Spark optical input.
