what with all the changes that have been made to iTunes and the Store.
Why not update iTunes on that G4?
You may want to consider upgrading the OS to 10.4 as well
Using a G4 with Mac OS 10.3. Unfortunately the computer hasn't been used in a few years and the software on it is out-of-date. It runs Itunes 5. Itunes radio stations work, but I can't access the music store, podcast directory, or sign in to my account. Is Itunes 5 not allowed to access the music store anymore?
