MultiTunes is defunct. It is incompatible with iTunes 10.4 because Apple completely rewrote iTunes using different technologies (it's now Cocoa based not Carbon based). To make MultiTunes work again would mean completely rewriting it as well, and I just don't have the will to do that.

What is MultiTunes?

MultiTunes is an iTunes plug-in that lets you manage multiple iTunes libraries simply and seamlessly from within iTunes itself. There is no external program to run. It will work on Intel or PowerPC Macintoshes running at least Mac OS X version 10.3 (including Leopard).

How does it work?

MultiTunes does not move any of your music files when you switch libraries. In fact, only 3 files are touched: "iTunes Library" and "iTunes Music Library.xml" from the "Home -> Music -> iTunes" directory, and "" from "Home -> Library -> Preferences". These 3 files are moved in and out of the holding directories in "Home -> Library -> Application Support -> MultiTunes".

Even though your music files are not touched by MultiTunes, you can still have multiple music libraries on different disks. After creating a new Library go to the "Advanced" tab in the iTunes preferences where you can change where the music files for that library are stored. Note that even if you change where your music files are stored, the 3 files that MultiTunes touches still remain in their normal place.

Try MultiTunes before you buy it!

MultiTunes is shareware. You can try it for a while to make sure it works for you. Then you can purchase a registration code for $15.99.


A Note About iTunes 8:

If you used version 1.3 when iTunes 8 came out your iTunes may have started giving you an error like this:

Here is how to fix it:

  1. Open your "Music" folder.
  2. Find and open the "iTunes" folder.
  3. Throw the file named "iTunes Library Extras.itdb" in the trash.
  4. Throw the file named "iTunes Library Genius.itdb" in the trash.

And that should fix it. Don't worry, the files will be recreated when you run iTunes next.
