Test LibraryMix with the music you actually own.
The external beta is being prepared for a small first group of testers. The goal is to test real libraries, different Macs and the quality of the mixes LibraryMix creates.
What to test
- First-time setup and Music automation permissions.
- Library audit and metadata refresh.
- LibraryMix Radio — especially whether the finished playlist feels appropriate to the chosen seed song.
- LibraryMix Rediscover.
- Spotify export.
- Overall usability, performance and reliability.
Mac compatibility
LibraryMix Studio itself supports macOS 11.5 and later. Apple's TestFlight app for Mac requires a newer macOS release, so TestFlight will be the main beta route on compatible Macs. A signed and notarised direct-download build is planned for older supported Macs that cannot run TestFlight.
Current beta limitations
Last.fm discovery and LibraryMix Gigs rely on third-party APIs. API setup is temporarily unavailable to new beta users while permissions are being finalised. The core audit, LibraryMix Radio, Rediscover and Spotify export features can still be tested without those APIs.
Before you start
- Keep Music installed and available on your Mac.
- When macOS asks, allow LibraryMix Studio to control Music.
- Choose an Audit Folder when LibraryMix asks for one. LibraryMix stores its audit CSV files there.
