MKPlayer
MKPlayer is a macOS media player from Rockysandstudio for playing local video and audio files, web videos, and some TV playback workflows.
What is MKPlayer?
MKPlayer is a third-party media player for macOS published by Rockysandstudio. It is designed to open a wide range of video and audio formats on a Mac, including common movie containers and music files that users may prefer not to handle in the default Apple apps. The app also supports alternate audio tracks, multilingual subtitles, custom subtitle loading, drag-and-drop opening, and video adjustment controls. Rockysandstudio documents Safari extension support for opening web video links in the player, and its support pages describe features for sending compatible playback to Smart TVs or Apple TV in supported scenarios. Users are most likely to encounter it as a manually installed media app, not as a built-in macOS component. It appears to be a legitimate consumer media application, but because media players can request local network access, browser extension access, and file access, users should review permissions in the context of how they use it.

Safety overview
Status: Mostly safe
This appears to be a legitimate media player from Rockysandstudio rather than a system component. It is generally low risk when installed intentionally, but it may request access to files, the local network for TV playback, and Safari extension permissions for web video handling, so users should confirm those permissions match their needs.
Recommendation: Keep it if you actively use it for local media playback, subtitles, or TV streaming features. If you do not recognize installing it or no longer use it, review its permissions and remove it through normal app removal steps rather than deleting random Library files.
