The news: Safari on macOS Big Sur beta 4 finally supports native playback of YouTube videos in 4K.

  • For years, videos could only be played in up to 1080p
  • Users were forced to choose Chrome or another web browser for higher resolution viewing

Our take: As somebody who watches (and creates) YouTube videos every day on a 5K iMac, this is a godsend. There was always some weird engineering explanation for why 4K videos never worked, but none of that matters anymore. Videos will look so much better than they used to.
