Q: Apple TV Airplay Works With One MBP, Not Other
I have two McBook Pros. Both are running exactly the same version of OS X: 10.8.5.
The difference is, my ATV 3 shows up in the menubar of one of my MBPs, one from mid-2012, and does not show up in the menubar of my other one (Late 2008).
In the 2008 one, in System Preferences, under "Displays," there is a checkbox (checked) that says "Show mirroring options in the menu bar when available."
But there is no familiar black triangle in the menu bar.
However, on my 2012 MBP, in the same location, above the checkbox I have the option "Airplay mirroring" and a dropdown menu for, presumably, whichever Apple TV I want to use. The black triangle is in the menu bar.
My Apple TV works with this computer, not the other. All three are on identical networks. As far as I can tell, all preferences on both computers are identical.
I've seen many frustrated threads about this issue, many of which have not been solved, but I have the bonus of having two computers running the same systems with which to test.
Now . . . what is going on here? I notice the silence from Apple on this issue has been deafening. Luckily, solving this for me would be convenient, not essential, as it appears to be with several unhappy users.
MacBook Pro, OS X Mountain Lion (10.8.4)
