You probably have heard of the big news that the new released macOS system called macOS High Sierra will finally come with system-level support for GPU-accelerated fixed-function HEVC/H.265 10bit decoding and encoding. HEVC stands for High Efficiency Video Codec, which is the successor to H.264. HEVC roughly doubles the compression ratio of H.264, enabling it to deliver similar video quality at roughly half the file size (or higher quality and resolution at the same file size). You can see the HEVC benefits comparing to H.264 below in detail.

HEVC can save space and bandwidth, which will be more and more important as more 4K and HDR video becomes available to stream. Apple says the standard can compress 4K video files to 40% of the size without losing quality, which will let iOS 11 and High Sierra users store more of their own videos before running out of drive space. Alternatively, you can keep an HEVC video file about the same size while doubling the amount of data, which will decrease the bandwidth needed to move 4K and HDR video around.

In addition, all High Sierra supported Macs will support HEVC, however, only very recent models will support any hardware acceleration. Newer Macs, including the late 2015 27-inch 5K iMac, the 2017 21-inch iMac, and MacBooks and MacBook Pros from 2016 and 2017, will support hardware acceleration for coding and decoding HEVC video. The Kaby Lake chips in the 2017 laptops also support HEVC decoding. Hardware acceleration means faster encoding times in pro apps like Final Cut and Motion, and longer battery life when you're playing back HEVC video. Older Macs running High Sierra will still be able to play back HEVC video, but the process is a little hardware intensive.

If your Mac is too old, we don't suggest you to upgrade to macOS High Sierra or even you upgrade to macOS High Sierra, we don't suggest you to play HEVC on the old Mac with macOS High Sierra system. If you have HEVC files and want to play them on older Macs, you'd better transcode HEVC to H.264 files in .mp4 .mov and .m4v formats. Even your Mac supports HEVC hardware acceleration, when you play HEVC on macOS High Sierra, you'd better make sure it is HEVC/H.265 MP4 video or H.265 MOV video cause no matter Mac video player or NLE software on macOS High Sierra, they support HEVC MP4 and HEVC MOV better than other HEVC codec videos.
