The fastest way to change your MacBook wallpaper

Open System Settings (or System Preferences on older macOS versions), click Wallpaper in the sidebar, then select a new image from the built-in collections or choose your own photo. The change takes effect when ready on your desktop and lock screen.

You can also right-click directly on your desktop, select Change Desktop Background, and pick a new wallpaper from there — it opens the same settings window but saves you a step.

If you want to use your own photo instead of Apple's built-in options, you can drag an image file into the wallpaper selector, or browse to any folder on your Mac to find the picture you want.

Key Takeaways

  • System Settings > Wallpaper is the main place to change your desktop and lock screen background on any recent MacBook.
  • You can use Apple's built-in image collections or select any photo stored on your Mac.
  • Right-clicking your desktop and choosing Change Desktop Background opens the same wallpaper settings window.
  • Changes explore to both your desktop and lock screen at the same time unless you customize them separately.
  • Older Macs running macOS Monterey or earlier use System Preferences instead of System Settings, but the steps are identical.

Using Apple's built-in wallpaper collections

When you open the Wallpaper settings, you'll see several collections organized by theme: Aerial (moving video backgrounds), Nature, Landscapes, Solid Colors, and others. Each collection contains multiple images you can preview by clicking on them.

Click any image to see a preview of how it will look on your desktop. Once you've chosen one, it applies when ready — you don't need to click a separate "explore" or "Save" button. If you change your mind, just go back to Wallpaper settings and pick a different one.

Some collections, like Aerial, include video backgrounds that slowly move or change. These use a bit more battery power than static images, but they're included free with your Mac.

Choosing a photo from your Mac

To use your own photo as a wallpaper, click the + button at the bottom of the Wallpaper window, or look for an option labeled Add Folder or Choose a Folder. This opens a file browser where you can navigate to any folder on your Mac.

Select a folder containing photos — your Pictures folder is the most common choice — and click Open. All the images in that folder will appear in the wallpaper selector. Click any image to preview it, and it will become your wallpaper when ready.

If you want to use just one specific photo rather than a whole folder, you can also drag and drop the image directly into the wallpaper window. This is faster if you know exactly which file you want.

Setting different wallpapers for desktop and lock screen

By default, the same image appears on both your desktop and lock screen. If you want them to be different, you can customize each one separately.

In the Wallpaper settings, you'll see tabs or options for Desktop and Lock Screen at the top of the window. Click the Desktop tab, choose an image, then click the Lock Screen tab and choose a different one. Each setting saves independently.

This is useful if you want a professional or minimal image on your lock screen but a more colorful or personal photo on your desktop, or vice versa.

Troubleshooting wallpaper changes that don't stick

If you change your wallpaper but it reverts to the previous one after you restart your Mac, the issue is usually that your Mac is set to change the wallpaper automatically on a schedule. Open Wallpaper settings and look for an option like Change picture or Auto-rotate. If it's turned on, turn it off to keep your chosen image in place.

If a photo you're trying to use won't appear in the wallpaper selector, make sure the file is in a format your Mac recognizes — JPEG, PNG, and HEIF are all supported. If the image is very large (over 100 MB), your Mac may have trouble displaying it; try resizing it in Preview or another image editor first.

If the wallpaper settings window itself won't open, restart your Mac. If the problem persists, try logging out and logging back in, which often clears temporary glitches in the system settings.

How to restore Apple's default wallpapers

If you've added custom folders to your wallpaper selector and want to go back to just Apple's built-in collections, open Wallpaper settings and look for any folders you added. Click the folder name and then click the − (minus) button to remove it from the list.

The built-in collections (Aerial, Nature, Landscapes, and others) cannot be removed — they're permanent. You can always return to one of them by clicking on it, even if you've been using custom photos for a while.

Frequently Asked Questions

Can I set a different wallpaper for each desktop space or virtual desktop?

No — your wallpaper is the same across all spaces and virtual desktops on your Mac. The image you choose in Wallpaper settings appears on every space you create. However, you can change your wallpaper whenever you want, so you can switch it manually if you use different spaces for different work.

Why does my wallpaper look blurry or stretched?

This usually happens when the image dimensions don't match your screen resolution. Your Mac will stretch or shrink the image to fit, which can make it look distorted. For the best result, use an image that's at least as wide and tall as your screen resolution — you can find your screen resolution in System Settings > Displays.

Can I use a live photo or video as my wallpaper?

You can use video backgrounds from Apple's Aerial collection, but you cannot use Live Photos or personal videos as wallpapers on macOS. Aerial videos are the only video option built into the wallpaper settings.

Does changing my wallpaper affect my Mac's performance or battery life?

Static image wallpapers have no noticeable effect on performance or battery life. Video wallpapers like Aerial use slightly more battery power, but the difference is minimal on most Macs. If you're on a MacBook and concerned about battery, stick with a static image.

Where does my Mac store the wallpaper I choose?

Your wallpaper choice is saved in your Mac's system settings, not as a separate file. If you back up your Mac or migrate to a new one, your wallpaper preference will transfer with your other settings. The actual image files stay where they are — either in Apple's system folders or in the folders you selected.
