I have a old Mac mini self upgraded to a 64bit Intel chip but still run OS 10.6.8. The latest Itunes I can run on this OS is 11.4 I got an Iphone 6s plus for Christmas only to find out Apple will not let Itunes and my Iphone pair up. Is there a work around to allow these two to talk or for me to load the latest Itunes on my mac?
