In this article we will tell you about how to sync iPhone to multiple Computers,  Here are the complete details:

Many people use multiple computers one for office work and the other for personal work  for storing music and movies. So very often there comes the desire to sync the iPad or iPhone with multiple computers. But iTune does not allow it, and it simply does not let you synchronize different kinds of applications in different computers.

Yet it is possible to do such a thing with your computers and iOS devices. iTune has been set so that by default it does not allow this kind of application but what if the settings are itself changed? Well then it can be definite connected to two computers.

In the first part of this tutorial, we will deal with changing the settings of iTune, and in the second part we will deal with the secondary computer so that it may have the same iTunes default settings.

1. By clicking on the ‘Finder’ symbol open a new Finder window.
2. Now from the Go select ‘Go to Folder’.
3. Type ‘~/music/iTunes/’ and then choose ‘Go’ button.
4. Open the TextEdit file –iTunes Music Library.xml by double clicking on it.
5. Note the Library Persistent ID value key. Do not modify the file before closing it. It must look close to this- D501EB4887717F8F.
