I'd like to find a solution to my problem. I recently moved to a dorm of around 1100 students, and each one of these students has a mediabox that is also an Airplay device.

Because of this, the Airplay service seems to completely destroy the sound on the client and make it very slow. I've worked around this by just disabling bonjour altogether by unloading the mDNSResponder and mDNSResponderHelper plists from the launch daemons, but this also makes the multicast announcements of my IPTV service fail.

I've tried blocking the bonjour packets to no success either (with Littlesnitch).

I'd just like it to not load the Airplay devices at all, so it doesn't get hogged up with them.

Information about my system: OSX 10.9.3 (on both a Macbook and an iMac). Things I've tried:

  1. Chmodding the mDNSService to 000 (doesn't work that well)
  2. Blocking the ports associated with Airplay announcements (5353)
  3. Completely unloading the mDNSResponder and mDNSResponderHelper

I'm connected through a wired network, and the announcements are sent via multicast announcements (as with my IPTV).

AirPlayXPCHelper /usr/libexec/AirPlayXPCHelper was hammering port 7000 on my local network. Port 7000 is not documented in Apple's who's who of ports and usage:

I found it using a light duty application network access monitoring and application firewall software package called Radio Silence.

Radio Silence is an all or nothing easy interface for process network access monitoring. https://radiosilenceapp.com. For those that find Little Snitch or HandsOff! a little too complex or overwhelming in the settings, this is a quick and dirty tool with a clean interface.
