MPlayer OSX Extended is a utility that comes as an alternative to using system's default player - QuickTime - for watching your favorite movies from your Mac computer. This program is the macOS version of the well-known MPlayer tool which was originally available only for the Windows platform.
The tool is great for users who switched from Windows to macOS and wish to play their movies with a utility that's similar to their previous media player.
MPlayer OSX Extended enables you to play movies with subtitles, gives you access to a wide range of video and audio playback settings, and brings you a built-in help guide. Furthermore, you can create playlists. However, you cannot export them to your local directories. Another disadvantage is the fact that you can't use MPlayer OSX Extended to watch SWF movies.
Still, MPlayer OSX Extended supports more file formats than Mac's default media player, is very intuitive, and offers you many useful advantages. And since you don't have to pay a dime to use it on your computer, it's definitely worth giving it a try.
