A few options all would be wired. You could use the built in audio output mini 3.5mm to rca, depending on the exact model most 3.5mm ports double as an optical output as well. You could go USB to an external DAC if you had one or on the other side of your macbook you may even have an HDMI output.Thinking of selling the 205, is there a way to directly connect my MacBook to the 720 in order to use Tidal? I would normally use the Play-Fi app but it doesn’t work (recognize devices) half the time. Here’s a pic of my MacBook inputs/outputs.
In tidal's desktop app settings it should show all of your sound output capablities. You would need to go there to toggle the output.
