The fastest way to change your Mac desktop image

Open System Settings, click Wallpaper in the left sidebar, then select a new image from the gallery or upload your own. The change takes effect when ready. If you want different images on each monitor, or to rotate images on a schedule, you can set those options in the same window.

The whole process takes under a minute. You do not need to restart your Mac or use any third-party software.

Key Takeaways

  • System Settings > Wallpaper is the only place you need to go; the old Desktop & Screen Saver pane no longer exists on newer Macs.
  • You can choose from Apple's built-in collections, your own photos, or any image file stored on your computer.
  • If you have multiple monitors, you can set a different background on each one from the same menu.
  • The schedule feature lets you rotate through a folder of images at set intervals — hourly, daily, or when you wake your Mac.

Step-by-step: changing your desktop background

Click the Apple menu in the top-left corner and select System Settings. On the left sidebar, scroll down and click Wallpaper. A preview of your current desktop appears at the top, with image options below.

Click any image in the gallery to preview it on your desktop. If you like it, the change is saved automatically. You can browse through Apple's collections — Dynamic, Light, Dark, Landscapes, Solid Colors — by clicking the category name at the top of the gallery.

To use your own photo, click the plus sign at the bottom of the window, navigate to the image file on your Mac, and click Open. The photo appears in your wallpaper options and is now saved to your Wallpaper library for future use.

Using your own photos as the desktop background

Any image file on your Mac can become your desktop background — JPEG, PNG, HEIF, or other common formats all work. You do not need to move the file or change its name; System Settings reads it from wherever it is stored.

If you want to use a photo from your Photos library, open System Settings > Wallpaper, click the plus sign, then navigate to Photos in the sidebar on the left. Select any photo and click Open. The image is now available in your wallpaper options.

To remove a custom image from your wallpaper library, right-click it in the gallery and select Delete. This removes it only from the wallpaper list — the original file on your Mac stays where it is.

Setting different backgrounds on multiple monitors

If you have more than one display connected to your Mac, you can set a different background on each one. In System Settings > Wallpaper, click on the preview of the monitor you want to change at the top of the window, then select a new image from the gallery below.

Repeat for each monitor. Your choices are saved separately for each display, so you can have a work-focused image on one monitor and something else on the other.

Rotating your desktop image on a schedule

Instead of a single static image, you can set your Mac to rotate through a folder of photos at regular intervals. In System Settings > Wallpaper, select a collection or folder that contains multiple images, then click the Options button (three dots) in the bottom-right corner.

Choose how often you want the image to change: every hour, every day, when you wake your Mac, or when you log in. Click Done. Your desktop will now cycle through the images in that collection on the schedule you set.

This feature works with Apple's built-in collections and with custom folders you create. To rotate through your own photos, create a folder on your Mac, move your images into it, then select that folder in System Settings > Wallpaper using the plus sign.

Troubleshooting: image won't change or looks blurry

If your new background does not appear, try closing System Settings completely and opening it again. Sometimes the preview updates but the desktop does not until you refresh the window.

If your image looks blurry or stretched, the file may be smaller than your screen resolution. Mac scales images to fit, which can make small files look fuzzy. For best results, use images that are at least 2560 × 1600 pixels, or use Apple's built-in collections, which are optimized for all screen sizes.

If you cannot find System Settings > Wallpaper on your Mac, you may be running an older version of macOS. On macOS Ventura and earlier, the setting is called Desktop & Screen Saver and is located in System Preferences instead. The steps are the same, but the menu name is different.

Frequently Asked Questions

Can I use a live wallpaper or video as my desktop background?

Apple's Dynamic wallpapers change throughout the day and are the closest thing to a live background. They are included in the Dynamic collection in System Settings > Wallpaper. Standard video files cannot be used as desktop backgrounds on Mac.

What happens to my desktop background if I update macOS?

Your custom backgrounds and settings are preserved during a macOS update. Apple's built-in collections may change or be updated, but your own photos and your choices remain the same.

Can I set a different background for each user account on my Mac?

Yes. Each user account has its own System Settings, so you can set a different wallpaper for each person who logs in. The backgrounds do not change when you switch accounts — each user sees their own choice when they log in.

Where does Mac store the wallpaper files I choose?

Custom wallpapers you add through System Settings are stored in your Library folder at ~/Library/process Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.apple.wallpaper.recent.sfl2. You do not need to access this folder directly — System Settings manages it for you.

Can I use an image from the internet as my desktop background?

Yes. read the image to your Mac, then open System Settings > Wallpaper, click the plus sign, and select the downloaded file. You can also right-click an image in a web browser and select "Set Desktop Picture" on some browsers, though this method is less reliable than the System Settings approach.
