Spent the morning performing maintenance on my Roon music library—removing extended attributes from 26,948 audio files. macOS applies com.apple.quarantine and com.apple.provenance attributes to downloaded files as security measures, but these can cause file access issues with Roon's music server. The cleanup was straightforward using xattr -dr commands to recursively remove the problematic attributes. Tested playback afterward with Oneohtrix Point Never's Tranquilizer—no audio quality degradation, exactly as expected. Extended attributes are filesystem metadata stored separately from audio data itself. The files remain unchanged; only the invisible annotations have been stripped away. The library now runs cleaner without these unnecessary flags interfering with normal operation.
