I keep getting dropouts and lost connections with my mac book pro with capitan OS over AirPlay on my Denon x4100. My iPhone and iPad work ok, just the Mac book causing issues. I've read on many a forum that the fix is to switch off Bluetooth on the Mac, however, this doesn't fix it for me. I've tried rebooting my router, receiver, Mac book and it sometimes works, but then just stops. I'm on the latest firmware on my x4100 and software on Mac. Any body else having these problems and is there a fix?
