My wife and I each have a login on our MacBook with a shared iTunes library. Only one of us can have it open at a given time, which is just fine. However, she is now the only user who can access the library. I get an error saying the iTunes library is locked, on a locked disk, or I don't have permission. I ran a fix of permissions just to check and see if that works, but to no avail. Any suggestions besides making a new library and copying the music over to it?
