iTunes will not sync with iPhone 6s
I am unable to sync my new iPhone 6s with my iTunes because it says my iTunes is not updated. My MacBook is from 2010 (Mac OS X Version 10.6.8), and I refuse to update to the newest operating system. Friends with the same model MacBook that have updated operating systems have seen poor results. I am using iTunes 11.4 which shows as the most recent update when I check for updates. Can I update to a new iTunes if I am not updating operating systems?
There should be a way to sync iTunes to my new phone. Please help!
I should not have to purchase a new computer or additional software to sync the two.
iPhone 6s, iOS 9.1
