Thank you for opening my thread. Ive had the iphone since 2007, and I now currently have the Iphone6+. I have a late model 08 MBP running the latest version of Itunes and Mavericks. For YEARS I have been making my own ringtones in Itunes, YEARS. But it NO LONGER works. Ive spent COUNTLESS hours trying to fiqure it out. Any intel about what has changed? is it a bug in ITunes?
