An MKV file format is nothing more than a multimedia container format. MKV files can incorporate different video, audio, and subtitles into one file. While this makes MKV a very versatile and adaptive file format, the problem is not many video players come with support for MKV files right out of the box. So the only way to play MKV on Mac would be to either download a player that supports MKV format, download an additional MKV codec for the player you already use, or convert the MKV file into a compatible one.
