One of the popular step-by-step guides here at About: Macs explains how to copy music from an iPod, iPhone, or iPad to a Mac. This technique can also help you rebuild an iTunes music library that may have been damaged, for one reason or another.

We've made a slight change in the guide that addresses a problem with getting an iPod to mount on the Desktop in Mountain Lion. In addition, we've added a tip that will help you open hidden folders in Mountain Lion.
Because the changes in the copying process are minor, we've simply updated the existing guide to ensure that it works with both Lion and Mountain Lion.
