Can't find AirPlay on macOS High Sierra
I have a mid-2010 MacBook Pro with macOS High Sierra 10.13.6 installed.
I have just found out that my Smart LG TV with webOS has AirPlay incorporated so, I would like to mirror my MacBook Pro screen on my TV.
However I can't find AirPlay on my MacBook. Already searched for some solutions on Google but the only option that I found was to go to Screen Settings on System Preferences and turn on "Show mirroring options in the menu bar when available" which it is. However the AirPlay icon doesn't appear in the Menu Bar.
Does anyone know how to solve this? Is my MacBook too old to support AirPlay?
