MacBook Pro will not AirPlay to apple TV
My MacBook Pro (Retina late 2013 Running 10.11.4) will not Air Play of late to my Apple TV. I can airplay from other devices (iPhone 6s) but not from my MacBook. There are no network issues (Wifi has been reset and confirmed working properly) but when I attempt to airplay from my computer I get the notification "Could not connect to 'Apple TV'." I've updated the software on my computer as well as gone as far as to update and restore the Apple TV.
I had a variety of random files get corrupted recently on my computer and I'm thinking that perhaps the files necessary to airplay got corrupted too?
If someone could point me towards the files to check and steps to get AirPlay to work again, that would be awesome! Thanks!
MacBook Pro with Retina display, OS X El Capitan (10.11.4)
