On your computer, find the downloaded image and click on the photo. Then click Apple Menu > System Preferences > Desktop & Screen Saver > Desktop. Mac: Find a wallpaper you love and click the blue “download” button just below. Find the image on your computer, right-click it and then click “set as desktop background.” Now the only thing left to do is enjoy your new wallpaper! When you click the “download” button, the wallpaper image will be saved, most likely in your “downloads” folder. Just below the image you’ll see a button that says “Download.” You will also see your screen’s resolution, which we have figured out for you.
