Trying to import iTunes Library to Apple Music on new computer
I have my iTunes library backed up on an external 1TB drive. I have long used a 2009 MacBook Pro running El Capitan 10.11.3. I recently purchased a new MacBook Air, running Sonoma 14.5, and am trying to get Apple Music to recognize the iTunes library. I have tried starting Music with Option held down, “Choose Library,” and then selecting the .itl file that is my iTunes library on the external drive. (I would prefer to run it from that drive rather than moving all the files to the new computer’s hard drive, since it takes a significant amount of space.) I then receive the error reading, “‘iTunes Library.itl’ does not appear to be a valid library. Please choose a different library.” I have tried re-copying the .itl file from my current iTunes library on the old computer to the external drive, but it still brings up the same error message. How can I use my old iTunes library on the new Macbook?
