I'm new at posting so please be easy on me. I am just wondering why I can't convert to AAC in iTunes anymore. I was just trying to make a ringtone in iTunes with the work round and it doesn't work anymore. I was able to do it before the last iTunes update. I am currently running iTunes ver. 18.104.22.168. Do I have to go back to an older version of iTunes to be able to create ringtones (for free) ?
