I thought DRM’d 4K HDR video streaming and playback support would come to the Mac in 2017 with 2017 Kaby Lake Macs. It finally comes in 2019 with macOS 10.15 Catalina, in the form of an Apple TV app. Dolby Atmos and Dolby Vision supported. iTunes and others like HBO supported but no mention of Netflix. Also, no mention of which Macs supported but I’m still guessing 2017 Kaby Lake Macs or later. --- Post Merged, Jun 3, 2019 --- Dammit all to hell. 2018 or later Macs required. 4K, 4K HDR, 4K Dolby Vision, Dolby Atmos, and HDR10 content is available on all Mac models introduced in 2018 or later with 4K-resolution screens. Some services require a subscription Dolby Atmos is available on Mac notebooks introduced in 2018 or later.
