AirPlay Mirroring has stoped working. Only audio but no video.

I am having the same problem except mine has never worked at all....just a black screen and audio. I have a Macbook Pro Retina Display. I just went into my router and disabled the 5ghz and now it is working fine.

I too am haveing the same porblem.

I have a Macbook Pro with Retina Diaplay, AppleTV 2 (720p), and Time Capsule.

All software and fimrare uodates are applied.

When selecting Airplay Mirroring from the menubar on the Mac, the apple TV displat goes to black, and only audio is transmited.

I have tried swithch the radio options on the Time Capsule as per mcbrian79's suggestion, but all options produce the same result.

Apple, please help....

You're not the only one.

Same problem, even applecare had no clue.

I've done everthing, reinstall, format, pram reset, disk utility, ...

But maybe I found an interesting temporarly solution:

Shut down the computer

Restart in safe mode (hold shift button when starting up)

When you are in safe mode, choose restart.

The computer will start in normal mode, then try to use airplay mirroring.

2 of the 3 times, I've got my desktop back on my tv.

Restart my computer again without going in safe mode --> back the black screen.

So going to safe mode en restart is helping.

Not a very good way to resolve it, I know.

Can anyone else try this pls?

Tried a reboot after booting into safe mode as you suggested, still the same result, just get the black screen on the AppleTV. No luck.

An interesting side note, tried the demo verson of the "AirParrot" app, and it works like a charm. Funny the third pary app works, but not the built in function of the OS. 😟

I think it was a lucky shot.

Because now it isn't working anymore.

Only one big black screen. With my parents macbook pro 2011 everthing works fine. But in their network my macbook retina still fail to show a display on the tv.

No luck either 😟

I think airparrot works in another way than the build in airplay mirroring from mountain lion.

Airparrot works but a lot slower.

Same here. Any solution yet? 😟

I'm happy. It's working again.

This is what I did, I hope it will help you to.

Go to library and delete all items in The map launchdeamons, Launchagents and startupitems.

After a restart, AirPlay mirorring works again.

I had to install some programs again but after that, The problem never occured again.

You are absolutely right! I cleared the LaunchAgents and LaunchDaemons folders (I have nothing in StartupItems) and restart, then voila! It's working now! 🙂

To play safe, I backed up those files onto the Desktop. And after Airplay Mirroring is working again, I restored those files to those folders and restarted again, and the mirrowing also works without problems!😁

I'm glad that it's also working for you!

Think we found The problem then. Whoehoe! :)

Worked like a charm!

Thank you so much for this.

A quick clarification for all that follow, this is in you top level system library, not your user library, which is hidden by default now anyways.

Thanks again!

For me, 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/LaunchDaemons. You need to re-install Parrallels. Could be a permissions thing, but I tried to repair permissions and follow Parallels instructions on how to start and stop the service. Even chown root and chgrp system. But only a ReInstall fixed Parallels. Which then kills Airplay Desktop Mirroring.

I Hope this helps... If you don't use parallels, then it still could be something in the /Library/LaunchDaemons or /Library/LaucnhAgents directories

How can i delete that file? im new at Mac OS....
