Q: I'm very disappointed that AirPlay does not work on my MacPro or Mac Air.

This is a technical problem support Forum.  Thank you for sharing.  And please, don't do it again.

Hope this helps

Then feel free not to promote it, why should you if you can run it.

I have a MacPro that won't even run Mountain Lion. Guess I won't promote anything in ML.

But I have a MBP that does run Airplay mirroring so I guess I will promote it. With the caveat that you need to have a fast WiFi network to really use it and to me it is not really that useful. I guess if I was connecting to large TVs or projectors for presentations it might be different.

You might take a flyer with AirParrot.

That's the problem with technology, it just keeps moving. You might want to save your anger for Intel, all Apple is doing is writing a line of code that use QuickSync in the Intel chipset. Wasn't available for the Intel chips in your equipment.
