VideoToolbox is preferred. Now that FFmpeg released 2.8, there's no reason to support VDA anymore. In fact, we had a bug that made VDA not useable with older FFmpeg versions in some newer mpv releases. VideoToolbox is supported even on slightly older OSX versions, and if not, you still can run mpv without hw decoding.
