Can't open iTunes Library.itl in Music on new Mac.
New Mac running Monterey. Old Mac running High Sierra. I've copied the full library from the old Mac to an external disc and I'm trying to point the new Mac towards the iTunes Library.itl file to import the library. All that happens however is a spinning circle and "Loading", going nowhere. I've looked at the structure of the folder and it seems normal - I've never had it split between locations. (I've also tried deleting the existing Music folder and replacing it with the old one - Music opens up and asks me to choose a library, but this doesn't even result in the loading circle, it just doesn't work at all.)
Can anyone offer a solution? Thanks
