One of my favourite Mac utilities has just been updated to add some excellent functionality. Airfoil now supports Chromecast and it works very well.
I’ve never understood why AirPlay from an iOS device only allows you to send audio to one speaker at a time, Airfoil is the perfect way to fix that. My MacBook Pro is normally on and so I AirPlay to Airfoils sister app Airfoil Satellite and then using the iOS Satellite app send the audio to what ever speakers I want. Since I have a Chromecast in my little studio I can now easily send Apple Music to my speakers without faffing around with cables. I put it to good use this morning streaming to both my studio speakers and kitchen speakers while I moved between the two rooms.
