Mountain Lion AirPlay Mirroring (iMac to AppleTV) Not Working

Mountain Lion successfully installed on my iMac.


AppleTV sucessfully networked with my iMac (at least where iTunes and iPhoto are concerned.)


But AirPlay icon is NOT appearing in my menu bar. Any clues as to why this is?


In System Preferences, I've checked "Show mirroring options in the menu bar when available" but still nothing.


Below is a screenshot of my menu bar. Thanks in advance!

Because iPhone's and iPads(newer versions) have on-GPU H.264. They can offload much of the mirroring heavy lifting to the GPU. You can have a 4 processor Quad core XEON server with a terrible graphics card and the iPad will still be able to do mirroring better with less resource drain.


Already pasted previously, but a good read for those that missed it and still don't understand why this isn't supported.

I feel for owners that don't have a GPU that supports mirroring. I just bought a 2011 Mac Mini, its going to replaced most likely in a couple months with a Ivy Bridge Mac Mini with USB 3.0 and Intel 4000 GPU. I can't cry that my USB ports are slow 2.0 version and why can't they be updated with a firmware update.

Sorry pj4u,


My story is similar to Ray in Naples and to me I am very disapointed that I have to purchase a third party software for airplay mirroring while i have already paid for the mountain lion upgrade.


Not to mention my hardware is a Pro Video editing monster: 17" macbook pro running Final Cut Pro.......

I7 CPU, 16GB Ram and 512GB SSD and another 1TB HDDdrive.


and honestly I am in the mood to purchase the Macbook Pro Retina since my current hardware is at par in performance.

My story is a little different. I purchased a new iMac (mid-2011)and apple tv (latest one) last week. My iPad and iPhones connect to AirPlay. Even my iTunes on my iMac connects no dramas.. Problem is I have no AirPlay icon on the top right bar of the iMac so I can't mirror. I've searched the forums and can't find any threads with people with compatible macs not being able to mirror. Any help would be appreciated.
