BeforeВ starting the screen saver, launch iTunes and start playingВ one of your playlists. The screen saver slideshow doesnвЂ™t have any options to play music, but you can make up for that by withВ iTunes. To start the slideshow right away, click the preview image. The last step is to check the вЂњShuffle slide orderвЂќ box. Select a collection and click the Choose button. Now you will see all the collections from your Photos library. At the bottom of the menu you should see the вЂњPhoto LibraryвЂ¦вЂќ item. Go back to the Screen Saver preferences and click on the Source menu. Afterwards, the button should become greyed out. Make sure that youвЂ™re in the General tab, and click the вЂњUse as System Photo LibraryвЂќ button. Then go to the Photos menu and select Preferences. If you donвЂ™t see вЂњPhoto LibraryвЂ¦вЂќ at the bottom of the Source menu, you need change your Photos preferences to use the Photos library as the system photo library. Use the Source menu to choose a set of images in Photos (e.g. Select the Screen Saver tab and then choose from one of the photo-related screen savers like вЂњKen BurnsвЂќ or вЂњClassic.вЂќ However, if you need that kind of control in creating your slideshow, you can use iMovieВ instead.Д¬lick the System Preferences icon on your dock,Д¬lick on the Desktop & Screen Saver preferences. ItвЂ™s not as full-featured as iPhoto as you lose the ability to control the slide time, transitions, titles and so on. If you donвЂ™t have iPhoto installed on your Mac, the only way to shuffle the photos in a slideshow is to use the built-in screen saver. Until then, hereвЂ™s a quick way to randomly play back a collection of photos in your Photos library. Hopefully Apple will reintroduce that feature back into the Photos app sometime soon. By shuffling the order of the photos, you can make the slideshow more interesting without spending time sifting through the whole album to find the best ones. If you play back the photos in the order they were shot, parts of the slideshow seem repetitive. Often weвЂ™ll have several photos of the same subject taken about the same time. This was a big loss for those of us who have to quickly create slideshows from a large number of photos for a party or school event.

When Apple replaced iPhoto with the new Photos app in OS X Yosemite, we lost the ability to shuffle (randomize) the slide order.
