Can't turn on airplay on mid 2011 macbook air
Hello,
I have a mid 2011 macbook air running El Capitan 10.11.5. I'm trying to turn on Airplay, but in the display window the drop down that says "Airplay display" is showing "off". But there is no option to turn it on. I've followed the recommended instructions. Any help? Thanks.
MacBook Air (13-inch Mid 2011), iOS 10.3.3, OS 10.11.5
