Pay more than fleeting attention to any Apple Mac advertising and you can not help but be struck by the incredible and engaging photography used to show off the capabilities of the screens of iMacs and MacBooks.
In this tutorial, I’ll uncover some breathtaking hidden photography – that is already on your Mac – and show you how to set this as your Desktop.
Desktops Detected
Personally, I tend to stick with whatever desktop image is supplied with that version of OS X. I’ve had various galaxies – in Snow Leopard, Lion and Mountain Lion – and now have a big wave in Mavericks.
But there is no requirement to stick with OS X’s default Desktop image. Changing your Desktop image is straightforward and is done from > System Preferences > Desktop & Screen Saver.
How to Change the Desktop Image
Navigate to > System Preferences > Desktop & Screen Saver and ensure that the Desktop button is selected.
In the lefthand pane, ensure that the Desktop Pictures folder is selected and, in the righthand pane, you will see a number of thumbnail images that can be used for your Desktop image.
A single click on any of these images will change your Desktop image immediately. You should be able to see the effects of the selection beneath any open windows on your display.
Uncovering More Stunning Photographs
There’s a collection of 43 National Geographic images that are used, by Mavericks, for screen savers. If you wish to view these, you will need access to the Library folder.
Ensuring that you have opened Finder, and it is in focus, press the Command Shift G keys to reveal a window into which you can enter the path of the directory you’d like to visit. Copy and paste, or type carefully, the following:
/Library/Screen Savers/Default Collections/
… and press the return key. This will open up the folder, within ~/Library that contains the National Geographic images.
Automatically Change the Desktop Image
If you like to change the Desktop image, periodically, you can tell OS X to change change to images within a particular folder and to change them every fixed time period.
The fixed time periods range from as little as five seconds up to one day.
If you want to use the National Geographic images alongside the existing choice of images, simply drag the folder(s) from Finder to the Desktop & Screen saver preferences pane. This will add that folder of images as available for Desktop images.
Using Images From iPhoto
If you already use iPhoto to manage your photography then this is a superfast way to use your own photo, especially if you have created any smart folders.
Navigate to > System Preferences > Desktop & Screen Saver and ensure that the Desktop button is selected. In the lefthand pane, select the iPhoto folder and navigate to the Events, Faces, Places or smart folder of your choice. Select any photograph to become your Desktop image.
Using Your Own Images
If you are using images, from other sources, that are not stored in iPhoto, I’d suggest setting up a folder for the purpose.
Create a new folder, called My Desktop Images within the ~/[Your user name]/Pictures folder.
Open a new Finder window and navigate to ~/[Your user name]/Pictures/My Desktop Images
Navigate to > System Preferences > Desktop & Screen Saver and ensure that the Desktop button is selected.
With Finder open, drag the My Desktop Images folder to the Desktop & Screen saver system preferences pane. When you see a white plus symbol inside a green circle, release the mouse and the folder will be added.
Using a Solid Colour
If your preference is for a clean Desktop, you may find that some images provide too much of a distraction to the extent that it is difficult to locate icons.
If this is the case there is, instead, an option to select a solid colour.
Navigate to > System Preferences > Desktop & Screen Saver and ensure that the Desktop button is selected.
In the lefthand pane, select Solid Colors to reveal ten blocks of different colour in the righthand pane. Click on any of these to change your Desktop to that colour.
If none of the colours work for you, click on the Custom Color button to reveal the colour wheel from which you may choose your desired colour and assign it to the Desktop.
Multiple Desktops, Different Images
If you employ multiple Desktops, on your Mac, it is possible to assign different images for each. Some people find that it aids their workflow to have different apps residing on different Desktops. It may also help to have a different image on each Desktop to provide points of reference.
New Desktops will inherit the image that is being used on Desktop 1. If you reorder the Desktops, it will be the new Desktop 1 from which the Desktop image is inherited.
If you already have a number of Desktops, you will need to go to each, navigate to > System Preferences > Desktop & Screen Saver and ensure that the Desktop button is selected, then select your chosen image for that Desktop.
