Method 2: MKV Player for Mac

What plays MKV files on Mac computer perfectly? Not QuickTime, not VLC, what I'm going to recommend here is a newbie, 5KPlayer, a fantastic MKV video player for Mac that I came across accidentally on forum.

It plays MKV video in 720p, 1080p, or 4K UHD on macOS Sierra, Mac El Capitan, Yosemite, OS X 10 without freezing or buffering. It takes no time to fully load MKV file. The player for MKV also plays AVI, FLV, MOV, MTS, MP4, MP3 music, AAC, to name just a few.

Another feature that impresses me is that it is able to airplay MKV video movie from Mac to Mac, from Mac to Apple TV. This means that you can watch MKV on Mac even on airplay supported TV with no limits.
