Question: Airplay mirroring broke in 10.9.2
i just updated to 10.9.2 and now when i try and airplay mirror to my Apple TV, it sends the audio but just shows a black screen and i can't drag anything to it. It doesn't show any of the options for external displays in the displays section of System Preferences.
Any ideas? i tried reapplying the combo update with no luck
iMac, OS X Mavericks (10.9.1)
