Airplay symbol not appearing despite following all steps on the troubleshooting page
I have a 13 inch mid 2012 macbook air updated to OS X Lion 10.7.5, and a second or third generation apple tv, updated with the latest software. The airplay symbol isn't appearing on my screen. I tried disabling firewalls, they are both on same network, I have restarted both devices. I can play music from itunes through the tv, but am not able to use airplay mirroring. Is there anything else I can try?
