upgrade to 10.8.2 left me with no music
My music, etc is stored on an external drive and has always worked fine. I activated a new Mac Mini with 10.8.2 and it now cannot "find" my music. I chose to "make a new library" and now have an empty media folder in "Music". The mini hard drive will not hold all the media I have on the external drive. I seem to have made a new .xml file (Gibberish seemingly) but have no library listing of my media. How do I et itunes to scan my external drive and create an actual library from which to operate?
Mac mini (Late 2012), OS X Mountain Lion (10.8.1)
