MPlayer OSX Extended
MPlayer OSX Extended is a macOS media player for playing many video and audio formats with subtitle, playlist, and fullscreen controls.
What is MPlayer OSX Extended?
MPlayer OSX Extended is a native macOS media player built to play a wide range of video and audio files. It uses the MPlayer and FFmpeg projects for playback and gives Mac users a straightforward desktop interface for opening local media, managing playlists, and watching videos with subtitle support. Common uses include playing MKV files, using embedded or styled subtitles, taking screenshots from video, and adjusting playback in fullscreen mode. The app also includes playback controls, an inspector, and audio and video equalizer tools for users who want more control over how media is presented. It is designed for people who want a lightweight alternative to more full-featured media suites on Mac. Development has been retired, so it is best understood as an older standalone media player for legacy macOS workflows.

Safety overview
Status: Mostly safe
MPlayer OSX Extended is a legitimate media player, but it is retired software and no longer receives updates. For a media player, normal file access is expected when you open videos, audio files, or subtitles from your Mac. The main practical risk is using an outdated app with modern media files or newer macOS versions, which can lead to crashes, playback issues, or unpatched security problems. If you still use it, avoid opening untrusted media files and prefer a current player for regular use.
Recommendation: Keep MPlayer OSX Extended only if you still rely on it for older playback workflows or specific subtitle behavior. If you no longer use it, removing it is reasonable and should only affect your ability to open media with this app and any settings it stored locally. For everyday playback, consider moving to a currently maintained media player.
