Q: AirPlay Mirroring. The ATV3 screen goes black.

When my mid MBP 2011 connects via AirPlay Mirroring. Mountain Lion.  The screen goes black. It has worked before. Now it doesn't.  I checked firewall, graphics switching and rebooting all devices.

 

Streaming via iTunes works fine. ATV3 can access my MBP's library.

 

thanks!

    I should also mention that Audio does work from Quicktime and other apps.  Just not Video.  The video screen on the ATV3 goes Black.

    Problem solved... sorta!

     

    It appears that Parallels 7 is not compatible with Airplay Desktop Mirroring in ML

     

    If you remove this file com.parallels.desktop.launchdaemon.plist

     

    inside

     

    /Library/LaunchDaemons

     

    then reboot.

    ATV3 now works again with Airplay Mirroring.

    However, it breaks Parallels.  And you simply cannot put the com.parallels.desktop.launchdaemon.plist file back inside /Library/Daemons.  You need to re-install Parrallels. Could be a permissions thing, but I tried to repaire and follow Parallels instructions on how to start and stop the service.

     

    I Hope this helps save someone some time...

    Thanks for all this information.  I downloaded the Trial of Parallels 8, installed it, re-started both Windows & Mac (Mountain Lion) and now AirPlay Mirroring is working again, even though it had the "black screen" problem before. Note that both restarts seemed necessary.
