🚀 Quick Start

1. Download latest release from Releases
2. Extract & run MusicMetaWriter.exe (Windows) / .app (macOS) / executable (Linux)
3. Load files or a folder via the buttons on the top left → start tweaking & exporting!

MacOS Users

Since I didn't join the apple developers program, I can't codesign my app now. So when you unzip the downloaded archive and try to open the app, it could tell you that the file is damaged, but its not. Apple adds an attribute to non-codesigned apps when unzipped from an archive.

Just run: cd Downloads sudo xattr -d com.apple.quarantine ./MusicMetaWriter.app

🛠️ Requirements

• Windows 10/11 (tested on Win11 x64)
