With the newest update of macOS, macOS Sierra comes to users' eyes. But like the update of other older versions, users have been or is going to encounter some issues with the macOS Sierra operating system, like iTunes with macOS Sierra not responding issue, macOS Sierra installation frozen issue, macOS Sierra can not run normally after update issue, macOS Sierra runs slow issue, etc among which the top one issue, the same as macOS other versions, is the video playback issue. Many users will report the preinstalled video player in macOS Sierra, QuickTime, can not play MKV, AVI, WMV, FLV, MPEG-1, MPEG-2, RMVB, WTV, SWF, 3GP, ASF, etc, but we all know that the above said video formats take a big part in video files.
Many users may recommend VLC media player. Yes, VLC media player can play lots of video formats, like MP4, AVI, MKV, AVI, WMV, etc, but not all of them, like AAF, DAT, MXF, etc. what's worse, when running the free VLC media player some problems will appear. For example the video is too dark, choppy; the video and audio can not sync; some subtitles can not be played; some DVD or other video file can not be played; VLC crashes.
