The fastest way to change your MacBook wallpaper

Open System Settings, click Wallpaper in the sidebar, then select a new image from Apple's built-in library or upload your own. The change takes effect when ready on your desktop and lock screen. The whole process takes under a minute.

If you want different images on your desktop and lock screen, or if you're using an older Mac, the steps vary slightly — but the principle is the same. You're always working through System Settings (or System Preferences on older machines) rather than hunting through folders.

Key Takeaways

  • Open System Settings, select Wallpaper from the sidebar, and pick an image from the library or your own files.
  • You can set different wallpapers for your desktop and lock screen, or keep them matched.
  • On Macs running macOS Monterey or older, the path is System Preferences > Desktop & Screen Saver instead of System Settings > Wallpaper.
  • Your own photos work best when they're at least 1920 by 1200 pixels, though smaller images will stretch to fit.

Finding and selecting wallpaper on macOS Ventura and newer

Click the Apple menu in the top-left corner, then select System Settings. In the sidebar on the left, scroll down and click Wallpaper. A panel will open showing your current wallpaper and a library of options below it.

Click any image in the library to preview it. Once you've found one you like, click it again to explore it to both your desktop and lock screen. If you want to use a photo from your own files instead, click the plus sign at the bottom of the library, navigate to your photo, and select it.

Setting different wallpapers for desktop and lock screen

After you've opened the Wallpaper panel in System Settings, you'll see two sections: one for your lock screen and one for your desktop. Click the lock screen section first, choose an image, then click the desktop section and choose a different one. Each section works independently.

This is useful if you want a straightforward, minimal image on your lock screen but something more detailed on your desktop — or vice versa. The lock screen image is what appears when your Mac is asleep or locked, while the desktop image is what you see behind your open windows.

Using your own photos as wallpaper

Click the plus sign in the Wallpaper panel and navigate to any folder on your Mac — your Pictures folder, Downloads, or anywhere else. Select the photo you want and click Open. The image will be added to your wallpaper library and applied when ready.

Photos work best when they're wider than they are tall (landscape orientation) and at least 1920 by 1200 pixels. Smaller images will stretch to fill your screen, which can make them look blurry. If you're using a photo that's portrait-oriented or very small, you may want to crop or resize it first using the Preview app before setting it as wallpaper.

How to change wallpaper on older Macs (Monterey and earlier)

If your Mac is running macOS Monterey, Big Sur, or an earlier version, the path is different. Click the Apple menu, select System Preferences (not System Settings), then click Desktop & Screen Saver. You'll see the same library of images and the same option to add your own photos.

On these older versions, you set the desktop and lock screen wallpaper separately. Click the Desktop tab to change your desktop background, then click the Lock Screen tab (if available) to change your lock screen. The process is otherwise identical to the newer method.

Troubleshooting wallpaper that won't change

If you've selected a new wallpaper but it hasn't appeared, close System Settings completely and reopen it. Sometimes the change hasn't registered until you restart the panel. If that doesn't work, restart your Mac — wallpaper changes almost always take effect after a restart.

If a photo you're trying to use won't upload, check that it's in a format your Mac recognizes: JPEG, PNG, HEIF, or TIFF are all standard. If the image is extremely large (over 50 MB), try compressing it first using Preview before adding it to your wallpaper library. You can also try moving the photo to your Pictures folder first, then selecting it from there.

Frequently Asked Questions

Can I set a different wallpaper for each desktop space?

No — your wallpaper applies to all desktops and spaces on your Mac at once. If you switch between multiple desktops, they will all show the same background image. You can only have one desktop wallpaper and one lock screen wallpaper active at a time.

What happens to my wallpaper if I update macOS?

Your wallpaper choice is preserved when you update macOS. If you're using one of Apple's built-in images, it will remain selected. If you're using your own photo, it will stay in your wallpaper library and continue to display after the update.

Can I use a video or animated image as my wallpaper?

Not through the standard Wallpaper settings. macOS only supports static images in the Wallpaper panel. If you want an animated background, you'll need to use a third-party app from the Mac App Store, though these can use more battery power than a static image.

Why does my wallpaper look blurry?

Your image is likely smaller than your screen resolution. If your photo is less than 1920 by 1200 pixels, macOS will stretch it to fit, which causes blurriness. Use a higher-resolution photo, or crop your current image to a landscape ratio before setting it as wallpaper.
