Airparrot 2.6.2 not running in macOS Sierra
I had an older version installed (1.5.3), just tried it under Sierra, connected to an ATV4, got this message on the ATV:


  This AirPlay connection requires iOS 7.1 or later, OS X 10.10 or > later, or iTunes 11.2 or later.


Then I tried AP 2.6.2, and it worked fine.
