HT1947 Home sharing doesn't work. I tried all the items in the troubleshooting section. It just sits there and says turn on home sharing in itunes in the remote app. It's on. Connecting to a library doesn't work either because my phone doesn't show up on

Question

Iphone 5. Anything else I can try? Itunes and iphone and the app are all up to date.

Answer 1

I brought my macbook air at home, everything worked perfectly: iPhone, iPad and Apple TV can connect. So basically I guessed that the issue was coming from the iMac, something preventing it to be discovered. I've checked the bonjour broadcasting and oh, surprise, the iMac wasn't broadcasting... Weird because it's a setup from a Time Machine, the environment I am running currently on the macbook air.
Anyway, if this can help someone else:
I've ran:
ps aux | grep mDNS
and saw that for the iMac the daemon was launched with the argument -NoMulticastAdvertisements.
I've setup the daemon to run back as normal and restarted the computer:
sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ProgramArguments -array /usr/sbin/mDNSResponder -launchd
After the reboot, everything works flawlessly (it has never worked before for the 6 months I had the Apple TV).
Also interesting discovery and I think it's new because I don't remember being able to do that before, but some of my devices are on the separate 5Ghz network, some are on the 2.4Ghz and they can still all communicate flawlessly. I can use AirPlay on the Export Express that is on the 2.4 from the iMac that is on the 5Ghz, and I can access the iMac library from whatever band. Pretty nice!
