You stare at that default "Ventura" or "Sonoma" abstract wave every single day. It’s fine. It’s clean. But honestly, it’s also incredibly boring. Your MacBook Pro is a powerhouse machine that probably cost you a small fortune, so why are you looking at the same wallpaper as every other person in the coffee shop?
Changing it is easy. Doing it right—so your icons don't get lost and your battery doesn't take a hit—is a different story.
If you're wondering how to change the background on MacBook Pro, you've probably already tried right-clicking the desktop. That's the shortcut. But macOS has evolved. Since the transition to macOS Ventura and the subsequent updates in Sonoma and Sequoia, the settings menu has shifted from the old "System Preferences" grid to a "System Settings" list that looks suspiciously like an iPad.
The Fast Way: Standard Desktop Customization
Let's get the basics out of the way. If you just want a quick swap, you don't need to dig through menus. Right-click (or two-finger tap) anywhere on your empty desktop wallpaper. Select Change Wallpaper.
This action teleports you directly to the Wallpaper section of System Settings. Apple organizes these into categories: Dynamic Wallpapers, Shifting Tides, Landscapes, and simple Colors.
The Dynamic Wallpapers are the clever ones. They use your local time to transition from high-noon brightness to a moody, dark-mode twilight as the sun sets. It’s a neat trick. Apple uses the HEIC file format to layer multiple images into a single file, which the OS then cycles through based on your clock.
But here is the thing: some people find the constant shifting distracting. If you're a video editor or a designer, a shifting background can actually mess with your color perception. In that case, stick to a "Still" image.
Using Your Own Photos (The Personal Touch)
Maybe you want to see your dog. Or a shot from your last trip to Kyoto.
Scroll to the bottom of the Wallpaper menu. You’ll see an "Add Photo" button or a section for your Photo Library. You can pick a specific album. If you’re like me and have 40,000 unorganized photos, don't do this. It’ll lag. Instead, find the specific image in Finder, right-click the file, hover over Services, and click Set Desktop Picture.
Boom. Done.
Aspect Ratio Dramas
Your MacBook Pro likely has a Liquid Retina XDR display. It’s a 14-inch or 16-inch screen with a very specific aspect ratio (usually around 16:10). If you grab a random photo from the internet that’s 16:9 or 4:3, it’s going to look weird. It’ll either crop out your friend's head or leave awkward black bars on the side.
Go for high resolution. We're talking 3024 x 1964 or higher. Anything lower will look "crunchy" or pixelated on a Retina screen.
Why Your MacBook Might Feel Slow After a Change
It sounds crazy, right? It's just a picture.
Well, not always. If you use one of the new "Aerial" wallpapers—those stunning slow-motion drone shots of Scotland or Dubai—you’re actually running a high-definition video file. macOS Sonoma turned these into "Screen Savers" that seamlessly settle into a static wallpaper when you log in.
They are beautiful. They are also heavy.
If you are running a base model M1 or M2 MacBook Pro with 8GB of RAM, and you have 50 Chrome tabs open plus Slack and Zoom, that high-res moving background is eating into your GPU resources. If you notice your UI animations stuttering, go back to a simple, static image. Your RAM will thank you.
The Multiple Desktop (Spaces) Trick
A lot of people don't realize you can have a different background for every "Space."

If you use Mission Control (swipe up with four fingers), you can create a New Space by clicking the "+" icon in the top right. You might have one Space for "Work" and one for "Gaming."
- Move to the Space you want to change.
- Open System Settings > Wallpaper.
- Pick a new image.
MacOS treats these as separate entities. It’s a great psychological hack. A clinical, grey background for work helps focus. A vibrant, colorful landscape for your personal time helps you disconnect.
Advanced Customization: The Third-Party Route
Sometimes Apple's offerings feel a bit sterile. If you want something truly unique, there are tools that go way beyond the standard "how to change the background on MacBook Pro" tutorial.
- Unsplash Wallpapers: This is a free app on the Mac App Store. It sits in your menu bar and can automatically refresh your background with high-quality photography from professional shooters.
- Wallpaper Engine: Originally a Windows staple, there are ways to get similar animated effects on Mac, though it's more taxing on the battery.
- Aerial: This is an open-source project that brings the Apple TV screen savers to your Mac. It’s far more customizable than Apple’s built-in version.
Fixing the "Folder of Images" Loop
If you miss the old days of your wallpaper changing every 30 minutes to a random photo from a folder, you can still do that.
In the Wallpaper settings, look for the "Auto-Rotate" icon (it looks like a circle of arrows) on any folder you’ve added. You can set the frequency—every 5 seconds, every hour, or every time you wake the laptop from sleep. Just a heads-up: if your folder is on an external drive or iCloud and that drive isn't connected, macOS will default back to the "Sonoma" wave. It’s annoying. Keep your wallpaper folder on your local SSD to avoid the reset.
Troubleshooting Common Issues
"I changed my wallpaper, but it didn't change on my external monitor!"
This happens constantly. macOS treats external displays as separate canvases. To fix it, you actually have to move your mouse cursor onto the external monitor, then open System Settings. The settings window will usually jump to that screen, allowing you to set a specific image for that display.
Another weird bug involves the "Lock Screen." Sometimes you change your desktop background, but the login screen stays the same old default. This is usually because FileVault is turned on. When you first boot up, the Mac hasn't "unlocked" your user settings yet, so it shows the system-wide default. Once you log in, it switches to your personal choice.
Summary of Actionable Steps
- Quick Swap: Right-click desktop > Change Wallpaper.
- Precision: Use images with at least 3000px width for Retina clarity.
- Efficiency: Disable "Aerial" moving wallpapers if your MacBook is running hot or lagging.
- Organization: Create a dedicated "Wallpapers" folder in your Pictures directory to keep things linked properly.
- Multi-tasking: Set different images for different "Spaces" to separate work and life.
Stop settling for the factory look. It takes ten seconds to make your workspace feel like yours. Whether it's a minimalist solid color to reduce eye strain or a high-res shot of the Pillars of Creation from the James Webb telescope, your MacBook Pro's screen is too good to waste on a default setting.
