1. Update your Sonos music library.
2. Open the macOS Finder app.
3. Press Shift + ⌘ + G and type in
   ~/Music/iTunes/
   .
4. Copy the
   iTunes Music Library.xml
   file.
5. Paste the file into the music library folder on the external USB drive that is being shared with Sonos.

Note that you will need to repeat the steps each time you update your Sonos music library.
