Hi Guys
I sort of figured it out. I was having the same problem as well and was really cheesed by apple for putting out a feature that doesn´t work. I have a late 2010 macbook pro and I figured it out.
Apple tv goes into sleep mode - at least mine does after 30 mins on standbye. If you try to mirror when your apple tv is on sleep mode....forget it. The Apple TV icon on the top right, just dissapears.
What I do and this is painful, is turn on the apple tv, and restart the macbook pro. Now there is a catch, don´t try and mirror it right after its booted. Wait a whaile for the system to "calm down" after its restarted. I get the idea that if the memory of your computer is not 100% available, the apple tv doesn´t pick it up and the whole thing just doesn´t gel....
Once all everything is fired up and looks like your macbook is waiting for you, try and mirror, but do it the following way:
- don´t use the icon on the top right of your desktop screen...tempting, but don´t go there...
- go the same place the icon shortcut would take you which is "system preferences", then click "displays" (under hardware) and you will see at the bottom left "AirPlay mirroring: choose the apple tv there.....
Hopefully it should do it.
I just lost my appletv icon on the top right of my macbook pro just as I write this. I thought I would check this thread again to see if someone smarter than me had found an easier way...but alas, no comments since the last time I checked.
So hope this helps....going to restart the macbook pro and do the schlepp procedure....when it does work, its great....just keep trying! I have had to restart 3 times before until it all came together! Its easier to get my 20 year old lawn mower to start!
Guys at apple...this seems simple to fix!
Looking forward to an update that gets this sorted out....you are almost there, just a few big bugs in the way!
Cheers guys!
