Upgrading from 10.5.8 to 10.8.5
I need to backup my iPhone 4 on iOS 7 but iTunes says that iTunes needs to be upgraded to the latest version, and to do that, I need to upgrade to 10.6.8
I have a MacBook (Late 2007 model) and it has not been updated since 10.5.8
I have the 10.6.3 Install Disc but if possible, I would like upgrade to 10.8.5.
I have purchased Mountain Lion on the App Store
