Users who want to stream Netflix content in 4K HDR through the macOS Big Sur operating system will need a Mac with an Apple T2 security chip,media reported. Netflix recently updated a Help Center page with new guidance on viewing 4K HDR content in Safari on macOS Big Sur, with operating system and hardware requirements.
According to support documentation, some Mac computers with Apple T2 security chips for 2018 or later are compatible with 4K content. In addition, all external displays must have 60Hz 4K functionality and HDCP 2.2 compliant connections.
Netflix can’t explain why Macs need t2 chips to play 4K HDR content. The chip does integrate many key controllers, such as the system’s image signal processor and audio controller, which have been shown to have a moderate increase in video encoding. Netflix may just have added T2 requirements to ensure that users are using a newer Mac with the current graphics component.
Apple noted in its support documentation that HDR video playback is limited to MacBook Pro models 2018 or later, MacBook Air models in 2018 or later, 2020 iMac, iMac Pro, 2018 Mac Mini and Mac Pro, while 4K is limited to iMac and iMac Pro models. There is no mention of T2 chip requirements.
Apple is expected to launch macOS Big Sur in the coming weeks.
