No Air for macOS Catalina?

[CongoFather]

Hi,
I think there is something wrong with your configuration. Maybe it's because you are using Devialet 200. I use both Audirvana and Roon on Mac Mini  with Catalina OS 10.15(19A602). Audirvana successfully supports AIR protocols(Devialet Air 3.0.4) and UPNP(I can play any song from NAS using Upnp on Audirvana).  Moreover, if you run some scripts, you can use "Direct Mode" and  enable Exclusive Access which bypasses the operating system and directly sends bit-perfect stream to the DAC using Ethernet. In this case, the streamer(Mac Mini, iMac etc.) and Devialet(in my case 220 Pro) are connected to a switch(audiophile switch is prefered) with ethernet cables.

Hi,

I don't think it has something to do with the Devialet 200. When installing Devialet AIR 3.0.4 on Catalina OS 10.15.3 it just won't install the driver. At this moment the software can't know which Devialet device you have. Excuse me for asking, but are you sure you're using Catalina? Strange situation...

I am currently listening Pat Metheny using Audirvana with Devialet Air Ethernet on MacOs Catalina 10.15. I did not install the latest updates in case "Direct Mode" does not work again for Audirvana. It is a little bit difficult to bypass Catalina and enable Direct Mode. I have run several scripts after installing Catalina to enable it.
