Hi John.
Firstly, you need to make sure you have the latest version of iTunes.
Then you need to download the Mac software from the B&O website for the Mac OS you're using, and install it.
Restart iTunes, plug in BS2. Hold down the GO button on BS2 for two seconds-docking station LED should change to red.
A few seconds later you should see a picture of the BS2 briefly appearing in iTunes.
BS2 should appear as a device in iTunes.
Drag and drop album onto BS2 icon.
This will place the tracks into a file called 'Music' on the BS2.
With BS2 device highlighted in iTunes click the '+' button underneath the devices list.
A new folder will appear which you can name.
Click on the Music folder, select all and drag to named folder for you album.
Now you have your music organised by album. Repeat as necessary!
Hope this helps.
Any questions, please PM me.
Best wishes,
Steve.
