Apple’s upcoming macOS Big Sur update appears to enable 4K video streams encoded using the HEVC codec, delivering Safari support for popular platforms like Netflix.
The forthcoming Safari capability was spotted by Ishan Agarwal, who shared the discovery in a tweet Monday.
During beta testing, Agarwal was served a 4K stream with Dolby Vision while viewing Netflix content on Safari in Big Sur. Dolby Vision is a branded HDR technology used by a variety of video streaming and on demand services to deliver content tailored to high-resolution screens.
