I have a large photo slideshow using the ken burns effect and custom music from my library. When i close out of the slideshow the music does not save. How can i get it to save?

There was a time when tracks purchased thru iTunes was still DRM protected. See if you can export a brief slideshow, 5-6 slides and one of the problem tracks as a slideshow. If exports OK then that track is DRM free.

Hi.

Where is the music from. If it is from a subscription service (eg apple music) then that is DRM protected and cannot be saved. You need to use music from CD's you have purchased and ripped into Apple Music, or purchased songs from apple music.

OK - that still works for me but you may be on a different version (what version of MacOS do you have?)

In any case instead of clicking the red dot (which instantly closes the app), try exiting out of the slideshow back to photos first, by clicking the left pointing "angle arrow" next to the three dots.

Then go back to your slideshow and see if the music is saved. If it is exit with the arrow again before closing and reopeneing photos and checking again.

Ok - I'm having no problems here, how are you closing out of the slideshow?

When you've selected music, is it appearing in the list top right of the screen, like this?

OK - thanks for letting me know. Sounds like a bug in your version of photos.
