Sync iTunes Library Between Multiple Accounts

Move the whole iTunes folder elsewhere on the hard drive where both accounts can see it. You will have to tweak iTunes a bit to see it, but then you have one library, usable by both accounts, rather than just by one.

- Quit iTunes
- Copy the iTunes folder (From ~/Music/iTunes) to the new location.
- Relaunch iTunes, holding the option key. Tell it you want to select a different library, and select the new location you moved the iTunes folder to.
- Open the iTunes preferences, and make sure that under Preferences > Advanced, that the "iTunes Music folder location" option points to the new location (It should usually end in 'iTunes Music').

Do the same on the second account (minus the copy/move step), and you should be good.

(WARNING: This is tricky, so you will want to be careful so you don't accidentally do something bad and lose your data, I would backup before attempting this if this sounds hard to do)

 

Mac to PC?

Is there any way I can sync my desktop computer's (running XP) Itunes library to my Macbook Pro's Itunes Library? My desktop is being used as the server for all our media. I can easily access the files and open with no problems. What I'm looking for is when I add files to my library on the desktop, my library will automatically update on the laptop so I don't have to keep track of it manually.
