So i upgraded the macbook pro to Catalina . i still Burn cd discs for use in car and older home theatre cd player. problem is now when i set gap to none i still have a gap between tracks.never had problem before using the old i tunes library/playlist as a way to burn . new Catalina upgrade changed i tunes to music (no longer i tunes) . anyway i let apple know and wonder if anyone has had a similar problem . i know cd's are old school and i use other options like my audio player that i can play flac on . but my old Subaru is cd only capable and still works fine playing cd's ( 6 disc capable ).
