IINA
IINA is a native macOS media player for watching local files and online streams with modern playback controls and subtitle support.
What is IINA?
IINA is a macOS media player built for playing video and audio files with an interface designed for modern versions of macOS. It helps users watch local media, open online streams, manage playlists, and control playback with familiar Mac features such as Picture-in-Picture and system media controls. The app supports a wide range of formats through the mpv playback engine and also includes subtitle features that are useful for movies, shows, and multilingual content. Users often choose IINA as a general-purpose replacement for older Mac video players because it fits well into desktop workflows and supports gestures, thumbnail preview, music mode, and browser-assisted opening of web video. IINA also includes a plugin system for extending playback behavior and adding custom tools.

Safety overview
Status: Mostly safe
IINA is a legitimate open-source media player for macOS. Its normal behavior matches its purpose as a desktop video player, including access to files you open and optional browser extension integration for sending online media to the app. Extra caution is most important with unsigned nightly builds, third-party plugins, and media opened from untrusted websites, because those can change the app's behavior or expose you to unsafe content. If you use browser integration or plugins, install them from sources you trust and review any requested permissions.
Recommendation: Keep IINA if you use it to play video or audio on your Mac. If you no longer use it, you can remove the app and its support files to free space without affecting macOS, but any custom settings, playback history, plugins, and saved preferences for IINA will be lost.
