My iMac won't mirror to my Apple TV they both have the updated software.

Bradhotdog, I have no such thing in my utilities folder nor elsewhere.

I don't have anything in my utilities folder called that either ian.mont have you found an answer?

Thanks Bradhotdog - it worked for me!

I had the same problem, I think, so I uninstalled AIR Display as stated and restarted the computer. It didn't fix my problem and I lost AIR Display…is there any way to get it back?

Struggling with the same problem for 3 full days. Although my problem was not due to airparrot, now working like charm with "uninstall airplay" solution. Thanks to bradhotdog and copythat23

I'm having a similar issue.

Brand new Apple TV unit, updated to the latest version.

Ethernet connection, so it isn't wifi related.

My boss's MBP Retina (10.9.5) won't mirror to it.

It will play music via his iTunes.

My Mac Mini (10.10.2) will connect fine.

My iPad will play music fine.

I can't mirror iMac on 10.10.3 but I can start up on an external HD running 10.6.8 and it does mirror iMac. Looks like 10.10.3 is guilty.

I might have found a solution? This works for me anyway. Like many on here i can get audio but no picture. I was using Air Parrot 2 to mirror my iMac before

so I'm know using both of them until hopefully apple come up with a solution I'm also on the new El Capitan. I am able to run both devices and works well on my TV . Hope it dose for you all.

Check it out... I have had the same airplay issue for over a year; however, it worked on my MacBook so I gave up on fixing it. Until today, several other discussions mentioned Air Display and Air Parrot, which I have never used; however, I forgot that I had tried Duet Display once. When I deleted it, I simply went to my application and moved it to the trash as you do with Apple Certified Apps, I also forgot that Duet Display was not downloaded from the App store it was done from a website.

IF YOU HAVE EVER USED DUET DISPLAY AND HAVE THIS ISSUE DO THE FOLLOWING!!!

THE FIX... Go to Duet Display's website, and reinstall the application. Once installed the D will be next to the airplay button. Click the D then click the option button (GEARS) and final click uninstall DUET. It will tell you that MAC will need to restart, say yes do it now... After restart your Airplay should work just fine. Took me less than 10 mins...

I cant believe it but it was Duet Display this whole time. Uninstalled it and now AirPlay works fine. So annoying.

Hi, I had this problem too. After a few different options I finally found this to work:-

System Preferences>Sound>Output>Apple TV

This was absolutely the answer for me. Duet was causing the problem.

Now I need to cancel Apple tech support before they call me this morning.

Thanks!
