Problem switching to a new Mac
On my old iMac (which I still have for now), I had a small SSD and a HD, and I used TuneSpan to access my music on the HD. I tried to use an external drive to transfer my music to my new iMac, so on my old iMac I told TuneSpan to move my music to a folder called "Music Library RS" on the external drive. That went fine. On my new iMac, TuneSpan said "Main iTunes library file missing: it wasn't found in its current location: (...)/iTunes/iTunes Library.itl (...) Whenever you change the library location in TuneSpan, you must make sure i`Tunes is set to load the same library." So I opened iTunes on the new iMac, went into Advanced settings and selected the path toward "Music Library RS" on the external drive. iTunes asked me if I wished to let it move and rename the files in the new iTunes Media folder, in accordance with the preference "Let iTunes organize the iTunes Media folder", I clicked yes. Then I reopened TunesSpan, which said Please allow TunesSpan to access files in "Library (on Mac HD)", but after I selected the path to "Music Library RS" on the external drive, I got the same error message "Main iTunes library file missing, etc". What am I doing wrong?
