itunes cannot connect to iphone
My 2011 mac mini runs with OS X Yosemite 10.10.5 and cannot update. The itunes on my mac mini hasn't had any problems before, but when i tried to recently connect my iphone 6 to the itunes on my mac, it says I need OS X 10.11.4, but there are no updates available on the app store for my mac and when I try to download them from the apple support site, it does not work.
