No need to fork out for Apple TV. This does exactly what it says on the tin. It’s only suitable for watching movies though, since there’s a 2-3 second delay.
#1 Solution to my problem!!!
I own a ‘Smart’ Panasonic tv and unfortunately no apps that I actually use are available such as HBO Go, ShowTime Anytime, etc. This was the solution to my problem without having to go out and purchase another HDMI cable or Apple TV. This app instantly mirrors what is displaying on my MacBook Pro onto my TV screen. Now I can watch anything I absolutely want! AMAZING! Totally worth $10!
