library.itl conversion to music.app library doesn't work, help needed.
Hello.
I finally updated my mac mini to the newest OS (used as music-server for locally stored ALAC and WAV files).
I then option-opened music.app to select the old library.itl and have it converted to the new format.
After a first run, it had the library converted, but all files (>10000) were marked as being in the cloud (thus, no ALAC, but 256bit mp4).
So I tried it again: quit music, deleted the new music-library, option-open music, select the old library.itl and then nothing happens, I get the "loading" rotating icon forever (~3 hours that is, I then aborted and did this several times, but nothing works).
I really really really don't want to start all over again, as there are many years of play-history etc. to which my listening habits and many finely tuned playlists are tied to.
How can I convert an old library.itl that already has been touched by music.app?
How can I get the local files be recognized by the app?
