Q: Apple TV can't find my Mac, restart discoveryd

I noticed after upgrading to Yosemite that often my Apple TVs couldn't find my Mac to play content from it, their main reason to exist. A reboot of my Mac fixed the problem so I dug deeper. I don't have to reboot anymore, I just have to restart discoveryd.

 

msoulier@merlin:~$ sudo launchctl list | grep discovery

264 0 com.apple.discoveryd_helper

1937 0 com.apple.networking.discoveryd

 

sudo launchctl unload /System/Library/LaunchDaemons/com.apple.discoveryd.plist

sudo launchctl load /System/Library/LaunchDaemons/com.apple.discoveryd.plist

 

So it seems that discoveryd has issues in Yosemite.

Mac mini, OS X Yosemite (10.10.1)

    Sounds silly, but have you rebooted your router?

    I've rebooted everything, just to confirm that the problem is what I think it is. I'm convinced it's discoveryd. I'd say Apple's testing standards are sliding.

     

    I've also had the Finder in Yosemite refuse to provide an options menu on files until I killed it and let it restart. Sad, and disappointing.

    My issues with itunes sharing on yosemite were being fixed by renaming my mini in System Prefs regularly. Restarting discoveryd is also solving the problem for me. Thanks so much.

     

    All these issues are a bug with Yosemite, and not "my network" as the fanboi's keep telling me.

    I have no idea what any of that means. I feel so lost.

    I've had trouble with multiple MacBook's ability to connect to my router after they wake up from sleep, or at random times. As soon as I restarted the discovery service, they connected to the network immediately. Previously I restarted the machine to fix.

     

    For anyone that doesn't know, the commands that msoulier wrote, are run from the terminal. You can launch the terminal from Applications to run more advanced commands on your Mac.

     

    As stated by msoulier; If you are having trouble connecting to your wifi router, try launching the terminal application and running the following commands, in this order:

     

    sudo launchctl unload /System/Library/LaunchDaemons/com.apple.discoveryd.plist

    sudo launchctl load /System/Library/LaunchDaemons/com.apple.discoveryd.plist
