Hi macrumors; I have used this site alot over the years and always found it to be the most knowledgable community for tough apple related questions. But now i have a doozie and can't find enough supporting info out there - please help!

I have a 2007 macbook who's hard drive I've replaced and am working on installing OSX. The goal is to have this computer and my 2014 macbook pro share a common itunes library (by doing option+click and selecting the other computer's ituneslibrary.xml file). The problem is this requires both OSes to use the same version of Itunes, which also, by extension means that i will have to try to roll my IOS version back in order to still be able to sync with the library.

My question: Has anyone successfully gotten the SAME VERSION of Itunes(most likely version 11.4) working on both an OS 10.7.5 Lion and 10.11 El Cap(?)

and the follow-up: Is it actually possible to revert an iphone back from ios 10.3 to ios8 or 9? (ios 8 would be required for itunes 11.4 to be an option).

thanks for your time! this community is seriously the best
-Mike
