Mountain Lion: Create an Instant Full-Screen Slideshow in the Mac OS X Finder

Something which I find myself using often on my Mac when I’m looking through a collection of pictures is the ability to quickly start a full screen slideshow.

To do this, select all of the pictures in the Finder that you want to view, then hold down the Command+Option+Y keys together to create an instant Full-Screen slideshow of the selected images:

You can Play & Pause the slideshow, click the Left and Right Arrows to manually go through the images and also add the selected images directly to iPhoto. I particularly like the Index Sheet option. If you click on the icon with the 4 squares, your slideshow switches to an index sheet allowing you to see the all images and select a specific one to switch to:

This feature has been tested using Mac OS X v10.8.1 which was the latest Mac OS release at the time of writing and also using the latest Internal and external Apple keyboards.

    I just got my first mac yesterday, and was trying to figure this out. Very happy to find this site.

  • BadAndy

    Thanks for this.
    As I am not a pro with Mac , it was much appreciated.
    Funny: can’t seem to find anything that OmniDragon or Russell Harris helped out with or spent time to help others, Oh sorry yes they do troll the “how to be a negative nilly”websites.
    Thanks guys

  • Thanks for the feedback Troy and Andy and glad to help.

    Please feel free to let us know if there is anything we haven’t covered that you’d like to know and if we don’t already know, one of us will hunt the Apple world down for an answer!

  • Well spotted Ian.

    You could also select all your pictures, then hold down the Option key and select the ‘Quick Look’ eye icon in any Finder Toolbar menu.

    Apple usually hide more than one way to do something, just a matter of choosing whichever one is the easiest/quickest for you to action!

    I’ve been using Mac for quite a while and just upgraded. On Tiger I would select images in a folder, right click, and there was a “slideshow” option. Now, under Mountain Lion, “slideshow” isn’t there which was frustrating me until I found this info. Thanks very much for stating what may be obvious to some but very helpful to others. I concur with BadAndy regarding OmniDragon and Russell Harris.

    Many thanks.

    When I do this it doesn’t display the slide show in the order in which I have arranged the icons in the Finder folder. Any ideas?

  • Hi SSA.

    The order you manually arrange the icons of pictures is irrelevant, the slideshow will default its displaying of images in the order specified in the ‘Arrange By’ setting in the ‘View’ menu of the Finder for the folder or by the ‘Arrange By’ category you have ordered the images by within the Folder’s toolbar.

    The ‘Arrange By’ categories are :Name, Kind, Application, Date Last Opened, Date Added, Date Modified, Date Created, Size and Label.

    So if you want them in a specific order, you could perhaps rename then ‘pic1’, ‘pic2’ etc and then arrange them by name.

    Hope this helps!
