I have a massive local library that was originally built with iTunes and then I done the onetime upgrade when Catalina came out and it all transferred over to the new music app with just a few errors. Now I have a new MacBook Pro and I can’t figure out how to transfer that local library from music on Catalina from my old MacBook. I’ve condensed the library etc but the .xml file is greyed out and I can’t select it to use the data for the existing library. I’ve done this numerous times before with iTunes but just can’t get it work from one old Catalina to a new Catalina laptop
