newer version of iTunes not acknowledged by iPhone
I have the new iPhone 6s. I also have a MacBook Pro. The first time I plugged the new phone into the computer, an iTunes message said "The iPhone cannot be used because it requires a newer version of iTunes." I went to itunes.com and downloaded the latest version. I have confirmed that I have properly downloaded the new version by going to "About iTunes". The scrolling message says I have 12.2.2.25. I've restarted my phone and my computer, but I continue to have the same message pop up every time I plug my iPhone in to my computer. I'm not sure how to resolve the issue.
Thanks for any help.
