Choose a Background Image
You'll see a preview of your current desktop and a list of image categories on the left, such as:
- Apple Wallpapers (built-in collections like Mojave, Big Sur, etc.)
- Photos (images from your Photos app)
- Solid Colors (plain color backgrounds)
- Folders you've added (custom folders with your own images)
Click on any category, then select an image to instantly set it as your background.

Use Your Own Photo
To set a custom image:
- Click the button below the image thumbnails (or drag a folder into the list).
- Navigate to the folder where your image is saved (like Downloads or Pictures).
- Select the folder — now you can choose any photo inside it.
- Click the image you want, and it becomes your desktop background.
You can also just drag and drop an image file directly onto the desktop, then right-click it and choose Change Desktop Background .
Adjust Display Options
Below the image preview, you'll see settings like:
- Fill Screen
- Fit to Screen
- Stretch
- Center
- Tile
Choose one depending on how you want the image to appear. “ Fill Screen ” is usually best — it scales the image to cover the entire desktop without distortion.
You can also check Change picture to rotate through a slideshow if you select a folder or album.
That's it — your Mac's desktop background is now updated. Basically just a few clicks, and you can switch it up anytime.
