Kid3
Kid3 is an audio tag editor for macOS that helps you view, edit, and organize metadata in music and other audio files.
What is Kid3?
Kid3 is a native audio tag editor for desktop users who want to manage metadata in music and other audio files. It is designed for tasks such as correcting album, artist, track, genre, cover art, and lyric information without re-encoding the audio. Kid3 supports batch editing, so you can update many files at once, generate tags from file names, and rename files or folders from tag data. It also supports multiple common audio formats and can convert between major ID3 tag versions for MP3 collections. On macOS, it is useful for keeping local music libraries clean and consistent, especially for users who organize large collections, audiobooks, or manually managed media files. Kid3 is published by K Desktop Environment e.V. and is also available on other desktop platforms.

Safety overview
Status: Mostly safe
Kid3 is a legitimate open source audio tag editor from KDE. Its normal behavior matches its purpose: reading and modifying audio file metadata you choose to open. Because it can rename files, edit tags in batches, and write changes across many tracks at once, review the target files before saving if you manage a large library or archival collection.
Recommendation: Keep Kid3 if you actively edit music metadata, clean up album information, or organize local audio files on your Mac. If you no longer manage a local media library, you can remove it without affecting macOS, though any tags or file names you previously changed will remain as edited.
