I have two itunes libraries. One is on Catalina and has a bunch of music. One is on Windows and has a bunch of different music. On the Windows machine I exported the Library xml file and copied the whole iTunes folder to my usb disk. I then went to the mac and opened the Library.xml file in a text editor and fixed up the paths to point to the correct location (e.g.
file:///Volumes/120GB SSD/iTunes/iTunes%20Media/Music/...) and then when I go into Music and import the Library.xml file, nothing happens.... no feedback on screen, no error messages, no items appearing in my library. I had console up to look at the logs but not really sure what I am looking for and nothing notable appeared. Music doesn't seem to even try to deal with importing.
How can I copy my whole iTunes library from windows into my EXISTING mac library?
