Hello everyone, and Happy New Year!

Here is a quick guide that will help you out importing iTunes playlists from your Mac to your N900. Hope it helps!

1) Create your iTunes playlists.
2) Download doubleTwist Sync, Play & Send software.
3) Install the application on your Mac and create an account so you can use it.
4) From doubleTwist go to Playlists - Playlist setup - Import iTunes Playlists (playlists will now appear on doubleTwist).
5) Connect your N900 to your Mac - Mass storage mode.
6) From doubleTwist go to Devices - Nokia N900.
7) Check Sync Music and choose the Selected Playlists option.
8) Now check the playlists you wish to send to your device and enjoy!

A new category will appear on your media player playlist section named: "Imported"(scroll down to find it) after syncing is complete.
Good luck!
