My iTunes 22.214.171.124 Is becoming unresponsive lately on my 15" Mid 2012 Macbook Pro ?? Suggestions ? Anybody else deal with this ? By the way i bought this laptop 2 weeks ago brand new and by the way i have 20,000 songs on it though is that the problem ? I have 367 GB free out of 500GB on my Macintosh HDD harddrive ???
