i have a problem which i can't solve.

My MacBook Pro Retina 15'' was able to use the airplay video mirroring on the AppleTV 3 without problems.

Some days ago, i saw, that the icon was not longer available in the menu bar.

The system settings just shows "No device found".


I can use the AppleTV for audio streaming without problems.

I tried another AppleTV (also with latest software) and it doesn't work, too.


So it seems to be a problem wirth my MacBook.

Is there any settings file, system component or other file, i should check (or maybe delete)?


I took a look into the system console and found the following entries regarding "airplay"

You can see, that i started audio airplay from iTunes, but there are two lines that may show some problem.


Does anybody have a hint?

    One additional hint: I can use the airplay video mirroring from my iPhone and iPad, it works fine.

    So it really seems to be an issue of the MacBook.


    I tried to perform the 10.8.2 combo update, bit it refuses to install. I found some hints, that this doesn't work due to the supplemental updates 1&2. This is really some bad situation, that there seems to be no combo update for my computer.


    Do i need to reinstall the whole system?

  • JvdL Level 1 Level 1 (10 points)

    Ok, i fixed it.

    Just for documentation:


    I started the MacBokk with Command-R

    I choosed to reinstall Mountain Lion

    After the system was installed again, AirPlay Mirroring was working perfectly again.

    I had to update the system again, but everything is fine again.


    All installed software is still working, so it was quite easy, no need to istall everything again.

    Checking the console output, now the AirPlay agent seems to work, so this was definately the problem:

    You can see it seems to start correctly in 1080p

    Unfortunately, after some weeks it now doesn't work again

    iPhone and iPad can do video mirroring, the MBP Retina can't.


    That's really anoying.

    Does anybody else have this kind of Problems on supported devices?

    I am experiencing the same problem on a MacBook Pro 13 inch Mid 2012 edition (non-retina). My other Apple devices (iPad and iPhone) work without a problem.

  • JvdL Level 1 Level 1 (10 points)

    Hi, did you manage to solve the problem?

    I still can't use the video mirroring.

  • kafecho Level 1 Level 1 (0 points)



    A few days ago I eventually did a PRAM reset on my MacBookPro 13 inch (the mid 2012 model). I followed the instructions at: http://support.apple.com/kb/HT1379. After the reset, AirPlay mirroring from my MacBookPro works fine.


    In the past, I also had issues with my Mac not correctly detecting external displays. The PRAM reset also fixed those.


    I hope this works for you.

    Hi, thanks for the hint, unfortunately it had no effect.

    The AppleTV still does not show up in the airplay video mirroring.


    Maybe i have to contact customer service about this, or file a bugreport.

  • JvdL Level 1 Level 1 (10 points)

    Finally i got the solution: After again reinstalling the System, Airplay Video Mirroring worked.

    To save some space on my internal SSD, i have copied the Apple Garageband and Logic Sound Libraries to an external hard drive.

    After setting the symbolic link to this hard drive, the Airplay Mirroring failed again.


    So I did some additional checking and found the problem:


    There is a driver in Macintosh HD/Library/Audio/Plug-Ins/HAL/AirPlay.driver

    OSX seems not to be able to resolve the symbolic link for this driver, so i copied it back to the internal drive and it finally worked again.


    Using symbolic links seems to be dangerous:-)

    Please report that to Apple via Feedback/Bug report.  Thanks.

    I have had this problem too. I read a solution that suggested going into the device you want to Airplay and change the language settings to another language, eg from English to French, allow the device to update, then change it back to English, it works a treat,  not sure why, but it does.
