SharePlay allows you to play and manage frequently viewed video streams and podcasts on your Mac. It natively supports external screens (including video projectors) and automated, fullscreen playback.
Here’s how it works: enter URLs to popular video podcasts, such as cable news programs. SharePlay will grab the most recent available program and play it. Build up a playlist of your favorite podcasts and watch them on your projector or external display!
