The good news is that it’s not hard to change the background on your Mac computer. Whether you want to switch to a favorite new photo, put up a dazzling image you found online, or rotate between a collection of your favorite backgrounds, we can show you how to change the background on a Mac the easy way.
Changing your background to another image
This option is for those of you who recently downloaded an image online or from a similar source and want to make it your background. It’s quick and simple, here’s how to get started:
Step 1: Exit out or downsize any windows on your screen so your Mac is focused on the desktop. In the upper left corner you will see the option to choose and open the Finder window. If you don’t already have a Finder window open, start one by choosing this option or using a keyboard shortcut.
Step 2: In the Finder window, search for the image that you want to use for your background. Make special note of what the image was called when you downloaded it, or just search your most recently downloaded images to find it. Make sure that it is the correct image. If you have saved the image to your desktop, the file icon should be visible out there as well, if you want to save a little time.
Step 3: Right click on the image to show the dropdown menu of everything you can do with it. Toward the bottom of this menu, you should see an option to Set Desktop Picture. Choose this, and this image should automatically be moved to your background. This gives you an opportunity to immediately see how it looks and if the resolution is acceptable.
Changing your background to a specific photo
Suppose you have a specific photo that you or a friend took, that you want to use for your Mac background. Here’s how to do it quickly!
Step 1: Make sure the photo is imported into your Mac Photos app. This may have happened automatically, depending on how your devices are set up. Open your Photos app (you can find it in Applications in the menu bar) and find the photo that you want to use as a background.
Step 2: Right click the photo that you want to use, and select Share. This will create a secondary menu of the places you can share the photo, and at the bottom you will find an option to Set Desktop Picture. Choose this.
Note: Photos also makes it easy to assign photos to specific screens if you have multiple monitors. Just drag the Photos app window to the monitor that you want equip with that background as you are working.
Advanced option: Set your background to rotate images
Can you just not make up your mind about the best image to use? Do you have a lot of favorites and like to switch a lot? It’s easy to set your Mac up to automatically switch between images, although it takes a bit more work. Here’s how to do it.
Step 1: Using the Finder, create a new folder and call it something easy like “Background Images.” Copy all the images that you really want to use as backgrounds, and paste them into this folder. Add any new images or photos that you also want to use as backgrounds. Anything you want for your background needs to be in this folder.
Step 2: Head to the menu bar and open up System Preferences, which you can find under the Apple menu in the top left corner of the screen. Once there, look for the icon for Desktop & Screen Saver and open it up. Make sure you are on the desktop tab and not the screensaver tab.
Step 3: In the select-an-image menu on the left, you should see a small plus and minus sign at the bottom. Select the plus sign, which will allow you upload a folder from your Mac. Choose the folder where your images have been collected, and add it.
Step 4: At the bottom of the window you will see an option to Change picture. Make sure this option is checked and that your folder is the source selected. You can then choose how often you want the desktop background to change. Choose something that works for you – we like changing the image once a day so every morning is something different, but if you want more of a slideshow feel, you can cut that down by a lot. You can also choose whether pictures are chosen randomly from the folder, or if they change in order.
