iTunes | Using Two Versions
This post is for those using the dot-method to revert to iTunes 10.7. One reason people revert to iTunes 10.7 is because it is a superior way to manage a very large music library. However, these same people probably use modern apple devices (iPod, iPhone, iPad, etc…).
If you only have one computer, it is possible to create two iTunes libraries. Then switch between iTunes 12 and iTunes 10.7.
