The desktop is often the first thing you see when you log into your MacBook. A well-chosen wallpaper can help you focus lift your mood or simply make your workspace feel more organised.

macOS allows you to choose from built-in wallpapers photos from your library solid colours and even dynamic backgrounds that change throughout the day. With just a few clicks you can make your MacBook feel more personal and visually appealing.
How to Change Your Desktop Wallpaper
The easiest way to change your wallpaper is by using System Settings. Begin by clicking the Apple menu in the top-left corner of your screen then selecting System Settings. In earlier versions of macOS this may be called System Preferences.
In the sidebar select Wallpaper. You will now see a preview of your current desktop background along with a list of available options. These are divided into categories such as Apple Desktop Pictures Photos Colours and Dynamic Wallpapers.
Click any image to instantly apply it as your desktop wallpaper. You do not need to save or confirm anything. The change happens immediately and you can switch as often as you like.
Using Your Own Photos as Wallpaper
If you want to use a personal photo or downloaded image as your wallpaper the process is just as simple. In the Wallpaper section select Photos or Folders depending on where your image is stored. You can choose pictures from your Photos app or from any folder on your MacBook.
Click on the image you want and it will be set as your new desktop background. If your image does not fill the screen properly you can adjust the layout using the Fill Screen Fit to Screen or Centre options available in the wallpaper settings.
You can also right-click any image file in Finder and select Set Desktop Picture. This will apply the image immediately without opening System Settings.
Dynamic Wallpapers and Light or Dark Mode
macOS includes several dynamic wallpapers that change appearance based on the time of day. These often feature landscapes where the lighting shifts from sunrise to nightfall giving your desktop a living feel. To use one simply select a wallpaper marked as Dynamic from the available options.
You can also choose between Light Dark and Auto appearance modes. Auto mode will switch your Mac between light and dark themes based on the time of day. When used with dynamic wallpapers this creates a seamless and visually cohesive experience.
Setting Different Wallpapers for Multiple Displays
If you use an external monitor with your MacBook you can assign a different wallpaper to each screen. First open System Settings > Wallpaper. Then drag the settings window to the screen you want to customise. From there choose a different image for that display. This gives you greater flexibility and helps keep your workspace visually organised.
Wallpaper Resolution and Quality Tips
For the best results use high-resolution images that match your screen’s native resolution. Most MacBook Air and MacBook Pro models have Retina displays with resolutions such as 2560 x 1600 or higher. If you use a low-quality image it may appear blurry or stretched.
When using photos from the web make sure they are high resolution and not copyrighted. Images from royalty-free websites or personal collections are usually a safe option. Avoid overly busy backgrounds if you want a clean and focused desktop.
Troubleshooting Wallpaper Issues
If your wallpaper does not change as expected first make sure your image is supported. Very large files or certain formats like TIFF may not display properly. Stick to standard formats such as JPEG PNG or HEIC for best compatibility.
If changes do not appear immediately try restarting your MacBook or logging out and back in. Occasionally a display setting or external monitor issue can prevent the wallpaper from updating correctly.
If System Settings does not open or shows an error when selecting a photo check your macOS version and update if necessary. Some features including dynamic wallpapers may require newer versions of macOS.
