Just re-installed Mac with Mojave. Installed back Roon. Was trying to save a song I liked to a specific playlist but when i choose ‘Add to Playlist’, there’s no playlist to be found. Then checked in the dropdown->X’s Stuff->Playlists. I could find the playlist there. But I also realised that there are two profiles that have got created. One that has my real name and the other my nick. I don’t recall creating these two profiles. How can I go back to having a single profile?
