Cog
Cog is a free, open-source macOS audio player for playing music in many formats with playlist controls and library-friendly playback tools.
What is Cog?
Cog is a native macOS music player focused on audio playback across a wide range of file formats. It is designed for people who want a lightweight desktop player for local music files, including users with mixed-format collections that go beyond the formats supported by simpler players. Cog supports common listening workflows such as opening individual tracks, building playlists, shuffling playback, and repeating songs, albums, or entire queues. It also includes user-facing conveniences such as gapless playback, global hotkeys, desktop notifications, and Last.fm scrobbling. The current maintained release is published by Christopher Snowhill for modern versions of macOS, making it a practical choice for users who want a straightforward dedicated audio player instead of a broader media library app.

Safety overview
Status: Safe
Cog is legitimate audio-player software for macOS. Access to your music files and media folders is normal for its purpose, and features such as notifications or media-key control are typical for a desktop player. As with any app that opens local files, use trusted audio files and downloads, and keep the app updated if you install it for regular use.
Recommendation: Keep Cog if you use it to play local audio on your Mac. If you no longer use it, you can remove the app like other third-party software, but doing so may also remove its saved settings, playlists, and related support files if you choose to clean those up separately.
