When Apple launched the Apple TV 4K streaming box and first announced support for 4K and HDR in the iTunes movie store back in 2017, it had managed to sign up most major studios. But there was one holdout in terms of offering its catalog in UltraHD: Disney.

For three years, users in Apple’s ecosystem had to settle for 1080p HD to watch, say, the Marvel movies or Pixar animated films. Today, it looks like that’s changing in the United States, Canada, and the United Kingdom. A plethora of Disney-made films inclusive of numerous Marvel, Star Wars, Pixar, and Walt Disney Studios animated films are available in Apple’s storefront in both 4K and Dolby Vision HDR.

Apple Terminal spotted a recently updated support document on Netflix’s Help Center that now includes hardware requirements for viewing 4K HDR content in Safari on macOS Big Sur.

According to the web page, viewing Ultra HD content can only be achieved on a “select 2018 or later Mac computer with an Apple T2 Security chip.” In addition to that, every monitor connected to the computer on which Ultra HD is streamed must be a 60Hz 4K capable display with a HDCP 2.2 connection.

It’s not clear why Macs need a T2 security chip to play back 4K HDR content, given that Windows machines obviously don’t, but
