Sharing your iTunes collection
The following assumes you want to keep all your iTunes music and movies on a shared folder and ensure new music is always stored there, and that you want to share the iTunes library among multiple users
First, you need to consolidate your iTunes Library to a folder you have chosen (let's say
External > Media).
Select the command consolidate library from the F
ile Menu > Library > Consolidate Library (or from the
Advanced Menu in iTunes 7). This will copy all your iTunes media to the shared folder and link the iTunes library file to it
The library library file (the index as it were) may still be in the Users > Me > Music folder of your mac G5.
If you want this file on the external as well as well, copy it to external iTunes folder, start itunes with the alt key pressed and you will have the option to select the library file now on the external
Select the library file you just copied and now both your music and the library are on the external
You can now use the same alt key trick on the new Mac Pro to get it to use that library file and link to all the music on the external
You may need to alter the permissions on the library file to make sure everyone has read and write access to the library file
