Apple TV Black screen (OS X Yosemite ) I have MacBook Pro (Retina, 13-inch, Mid 2014) and also a third generation Apple TV. Lately, especially after 10.10.3 update for OS X Yosemite, I am having mirroring issues.

I have checked all the links, forums etc on google and still no luck. 

The problem is basically, my ipad 2/iphone 5 can successfully mirror to Apple TV, but when I try to mirror my MBP, it only shows black screen with audio..

I cannot control the apple tv settings from my menu bar on MBP either. It does not let me choose whether to extend my desktop or mirror built-in display.

On web, I read forums with similar questions but they are generally left unanswered or did not work for me. 

Thanks in advance xxx
In cases where something appears to work, but it is not following your commands:


Logging as different user and try again, to check if your profile/permissions needs repairs.
Open Disk Utility located in your utility folder, and use the Repair Permissions.
