Airplay MacBook Pro

I have a Macbook Pro, running Sierra and the latest version of Djay Pro bought today.
I cannot find the Airplay icon in Djay Pro anywhere and have not found any information eluding to where it might be other than next to the master volume button where it is not.

Any help would be appreciated

Hi Steve Henry,

thank you for your post. Is your Mac AirPlay ready and is AirPlay turned on?
