iPhoto: "The music you selected cannot be opened" Alert

When you try to play a slide show in iPhoto, an alert box with this message appears:

"The music you selected cannot be opened."

If a music file has been moved in the Finder, iPhoto may not be able to locate it for a slide show. If iTunes 3 reorganized a music library, for example, the message will appear.

You can resolve this issue by reselecting the music file.

1. Select the photo album you want to use for your slide show.

2. Click Share in the iPhoto window.

3. Click Slide Show in the iPhoto window.

4. Choose Edit from the "Music" pop-up menu.

5. Select the track that is not playing correctly from the music list.

6. Click Delete.

7. Click Done.

8. Choose Other from the "Music" pop-up menu.

9. Locate the music file you want to use in the Open window.

10. Select the music file and click Open.

11. Click OK.
