Part 2. Sync iPhone with Multiple Computers with iTunes

If you are too possessive about your iPhone and do not want to experiment with any new software for syncing needs, then iTunes can also be used to sync the iPhone with multiple computers. Though at first instance, this may sound against the working of iTunes, in reality, it can be done by tricking your iPhone. While connecting your iPhone to the new computer, you can trick it in a way so that it thinks that it is connected to the same old library. Understanding deeply, iTunes library which is linked to your iPhone or other iOS devices is recognized by Apple based on Library Persistent ID key which is hidden on your PC/Mac. If you can copy and paste this key between multiple computers, you can track your iPhone by making it think that it is connected to it’s originally iTunes library. Thus using iTunes as well, you can sync the iPhone to multiple computers.

Steps to Sync iPhone with Multiple Computers with iTunes

Step 1. Open the new Finder window on the Mac system that you use to sync your iPhone normally, and then from the top menu bar, navigate to Go and select “Go to the folder:” option from the drop-down menu.  Once the text prompt opens, type “~/Music/iTunes” and then click on Go.

Step 2. A list of files will be shown and from this list, you need to backup .itdb, .itl and .xml files along with the “Previous iTunes Libraries” folder.

Note: Though the selected files are needed for the process from the given list, it is recommended to backup all the files so that you have a copy of these files if anything goes wrong.

Step 3. Open the file “iTunes Music Library.xml” with TextEdit and search for the Library Persistent ID, which is a 16 character string,  and copy it. Make sure not to change anything in the file.

Step 4. Now open the new/secondary Mac system with which you wish to sync your iPhone. Repeat the above 1- 3 steps on the new Mac. Ensure that iTunes is closed on this system.

Step 5. Now on the new/secondary Mac system delete all the files with .itl in the folder “Previous iTunes Libraries”. If you do not find this folder in your system, skip this point.

Step 6. Open “iTunes Music Library.xml” on a new/secondary Mac system with TextEdit and find the Library Persistent ID. Here the ID on the new/secondary Mac system needs to be replaced with the ID string that was copied from the original or first system. Replace the ID that was received in step 3 and save the file.

Step 7. On the new/secondary Mac system, open “ iTunes Library.itl” with TextEdit and all the contents in this file needs to be deleted. Save the file.

Step 8. Now launch iTunes on a new/secondary Mac system. An error - The files “iTunes Library.itl” does not appear to be a valid iTunes library file. iTunes has attempted to recover your iTunes library and renamed this file to “iTunes Library (Damaged)”.” will appear. Ignore the error and click “OK”. Connect iPhone to Mac and you can sync it with iTunes library on this system.

Once the above steps are completed, you would be able to sync the iPhone with two computers without erasing any existing content.

So whenever someone asks you if you can sync an iPhone to two computers, you can confidently say Yes.
