My new apple tv does not work with my new macbook pro. No silly box/triangle icon shows up on the operating system. I cannot use airplay. No help anywhere. No documentation. No diagnostics. Just fail. Fail. FAIL. Now my Apple TV will not upgrade...it tries and FAILS.
AirPlay Mirroring requires a second-generation Apple TV or later, OS X 10.8 or better and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). It also requires the computer to be using wi-fi.
