[OS X] AIRPLAY not showing up in Mountain Lion

Click for full size
The machine in question is a late-2009 27 inch iMac.

After installing ML, the airplay logo is not displayed in the bar at the top.

Interestingly enough, the airplay logo and apple TV on my network shows just fine in iTunes on the same machine.

Please help. Thank you.

Editor's note:Unfortunately, AirPlay Mirroring only works on Macs made in 2011 or later.

I know I just found this out! I should have read the real fine print but was expecting to be able to mirror my mid 2009 Mac Book Pro. Really sucks.

Thanks for the quick reply.

What a rip off. :-( There is no hardware issue/bottle neck preventing it from working just fine.

I think it's the hardware H.264 encoding that is enabled on the Sandy Bridge and newer platforms. That's what I was told anyways.

Yes there is. Your Mac does not have a processor with Intel QuickSync (hardware h264 encoder/decoder). So it would have to use the general CPU to do the compression, which would ruin system performance.

You should still be able to use AirPlay for audio.

I have a 2011 13" MBP, installed mountain lion lastnight from the Appstore, all good. I noticed Airplay icon is only showing up when connected via cabled network connection. When using wireless, no airplay icon.
Dont despair everyone, maybe this is a bug?
Our iphones see the appletv all the time over WiFi

Then how come iPads and iPhones are able to do it?

The iPhone doesn't do AirPlay mirroring. The new iPad and iPad 2 have hardware encoders to mirror the display to Apple TV.

As for AirPlaying video, if the video plays on an iPhone/iPad it's already in a format that will play on the Apple TV so there's no need to encode it.

The A4 and A5 have hardware H.264 acceleration built-in.

My iPhone 4S can do mirroring.

I just tried AirPlay mirroring a live feed of the Olympics through my Apple TV. Looked like absolute shit--the shot on the TV had all kinds of trouble catching up to what my laptop screen was showing. Im wondering where the bottleneck is. I have a G wireless router, but Im not sold that it was the bottleneck.

My mistake, I have iPhone 4, it doesn't. Seems like devices with an A4 can't do the needed encoding for mirroring.

Guess you're right. I could check with my wife's iPhone 4 when she gets home but perhaps it is just limited to the iPad 2 and the iPhone 4S with their A5s for video mirroring.

Are we talking about the same thing? I can AirPlay videos from my iPhone 4, I'm talking mirroring what's on the iPhone screen to an Apple TV including the launchpad icon screen.

4S does full mirroring, 4 does not.

This. When you stream video you aren't mirroring the video - it's just sending the datastream to the AppleTV for processing and viewing. When you mirror your iPhone or iPad creates a data stream in H.264 format of what you're seeing on your screen and sends that to the AppleTV. That's why hardware encoding is so important - sending a raw, uncompressed datastream would be too demanding on the network and using the general CPU to do the encoding would hit system performance greatly.

Use AirParrot: »airparrot.com/

Problem solved ...

PS. It does use your CPU instead of the GPU as the method built in ML, so it is quite intensive.
