Hi and thank you, I am currently running iTunes 11.2.2 on a MacBook Pro with Mac OS 10.6.8 and have an iPhone 5S with 7.1.2 installed. Everything is great now, but there are features on iOS 9 that I would like to use. Will I run into any issues with syncing or compatibility if I upgrade to iOS 9 for my iPhone? I don't plan to move beyond 10.6.8 on my MacBook for now. I understand this is an old OS, but it works for me, and the process of ensuring my workflow needs aren't interrupted is pretty paramount at this time, so I also am wary of upgrading iTunes, though 11.4 is possible, I think, on 10.6.8. But will 11.4 run iOS9? I've read a few threads about this, but can't seem to find a definitive answer. People come up with funky workarounds sometimes, but I'm looking for a straightforward approach. I appreciate your help.
