I've seen this icon in a tutorial I watched on YouTube. What app is this icon? Have searched through Google Images but found nothing.

That is the icon for AirPlay, by Apple, and that menu bar item allows you to control the streaming/mirroring of content on your Mac to an Apple TV or other AirPlay server.

Turning AirPlay Mirroring on and off

If your Mac supports using your Apple TV as a display, an AirPlay menu appears in the menu bar when an Apple TV is on the same network. The AirPlay Mirroring menu icon turns blue when AirPlay Mirroring is on ().

  • Your answer seems to be totally wrong. Can you provide a reference for it? The Chromecast icon has little quarter circles coming from the lower left corner. Commented Jul 30, 2017 at 18:17
