My macbook pro 13 inch early 2011 don't have an airplay mirroring. What should I do?
It is your OS, you need to purchase OSX 10.8 Mountain Lion from the app store as this is the OS for mirror, your MBP will support it.
if you don't run Mountain Lion you don't have mirror and
if your mac is not listed as supported you don't have airplay mirror
MBP early 2011 does support mirror with mountain lion.
