It only shows my computer and my Amazon Echo (connected via wifi). With my speaker system connected to wifi and Chromecast (via Google Home mobile app), the Spotify desktop app still doesn't recognize it in the devices list. This is my first time having to use Chromecast and I'm having trouble it working seamlessly. Important to me is to be able to play music to this device over wifi in my Spotify Mac desktop app.Īlthough this speaker system isn't specifically listed as compatible with Spotify, the device does support Chromecast, which Spotify Connect appears to support. I just purchased some speakers (Polk Magnifi Mini) that has wifi capability (and Bluetooth). Operating System: MacOS High Sierra 10.13.6 Connecting to Chromecast Device on Mac Desktop App.
