Do you run Mixxx on macOS? We need your help to test two fixes: accessing a traktor library from sandboxed Mixxx (https://github.com/mixxxdj/mixxx/pull/16205) and also rekordbox (https://github.com/mixxxdj/mixxx/pull/16237)

Follow those links for more details and links to download testing images.

This should be a safe process, but If you have any doubts, back up your settings and library just in case! (https://manual.mixxx.org/2.5/en/chapters/appendix/settings_directory)
