How to Change Screen Saver on Mac: A Complete Guide

Mac screen savers have come a long way from simple bouncing logos. Today they range from elegant aerial photography to artistic shader displays — and macOS gives you precise control over when they activate, how they behave, and what they show. Here's exactly how to change your screen saver, what settings matter, and what affects the experience depending on your setup.

Where to Find Screen Saver Settings on Mac

The screen saver controls live in System Settings (called System Preferences on macOS Monterey and earlier). Here's the path:

macOS Ventura, Sonoma, and later:

1. Click the Apple menu (🍎) in the top-left corner
2. Select System Settings
3. Click Screen Saver in the left sidebar

macOS Monterey and earlier:

1. Click the Apple menu
2. Select System Preferences
3. Click Desktop & Screen Saver
4. Select the Screen Saver tab

Once you're in the right panel, you'll see a preview window and a list of available screen savers on the left.

How to Change Your Screen Saver

Changing the screen saver is straightforward:

1. Open the Screen Saver panel using the steps above
2. Browse the available options — macOS groups them by category, including Landscape, Cityscape, Underwater, Earth, and more on newer systems
3. Click any option to see a live preview
4. Adjust options if available — some screen savers let you customize speed, display style, or shuffle behavior
5. Set the start time — use the "Start after" dropdown to choose how many minutes of inactivity trigger the screen saver

Your changes save automatically. No confirmation button needed.

Understanding the "Start After" Timer

The inactivity timer is one of the most practically important settings. Options typically range from 1 minute to never. This interacts directly with your display sleep timer in Energy Saver or Battery settings.

A common point of confusion: if your display is set to sleep before your screen saver is set to start, the screen saver will never appear. For example, if your display sleeps after 5 minutes but your screen saver starts after 10 minutes, you'll only ever see a black screen. Make sure your screen saver timer is shorter than your display sleep timer if you actually want to see it.

Screen Saver Options Available in macOS

The selection varies by macOS version and Mac model, but most modern systems include:

On Apple Silicon Macs running macOS Sonoma or later, the aerial-style screen savers are rendered in high quality with smooth transitions and can display live weather-based scenes. Older Intel Macs running the same OS may show the same screen savers but with reduced animation fidelity depending on GPU capability.

Using Your Own Photos as a Screen Saver

If you'd rather display personal photos, macOS supports this natively:

1. In the Screen Saver panel, look for Slideshow or Photos options
2. Select the source — this can be your Photos library, a specific album, or a local folder
3. Choose a display style: Classic, Ken Burns (slow pan and zoom), Shifting Tiles, or others depending on your macOS version
4. Adjust the slideshow speed if the option is available

The Ken Burns effect adds gentle motion to still images and tends to look polished on larger displays. On smaller screens or older hardware, you may prefer a static or simpler transition style.

Third-Party Screen Savers 🖥️

macOS supports installing third-party screen savers as .saver files. A popular example is the Aerial screen saver, which replicates Apple TV's aerial footage with additional customization options not available in the built-in version.

To install a third-party screen saver:

1. Download the .saver file from a trusted source
2. Double-click the file — macOS will ask if you want to install it for your user account or all users
3. Once installed, it appears in your Screen Saver list

Important: macOS Gatekeeper will flag unsigned screen saver files. You may need to right-click and choose Open the first time, or allow it in Privacy & Security settings. Only install screen savers from sources you trust, as .saver files can execute code.

Screen Saver vs. Lock Screen: What's the Difference?

These are related but separate. The screen saver activates after inactivity and displays visual content. The lock screen requires a password to regain access.

In macOS, you can configure whether your Mac requires a password after the screen saver begins — this is set under System Settings → Lock Screen (Ventura and later) or System Preferences → Security & Privacy → General (earlier versions). The delay before requiring a password can be set to immediately, or after a short grace period.

Variables That Affect Your Screen Saver Experience

The right screen saver setup isn't one-size-fits-all. A few factors shape what works best:

• macOS version — Sonoma introduced new scene types and improved transitions not available on older systems
• Mac model and GPU — high-resolution animated screen savers are more demanding; older Macs may stutter on complex scenes
• Display size and resolution — aerial and photo-based screen savers read very differently on a 14-inch laptop vs. a 27-inch Studio Display
• Use case — a screen saver on a home desktop serves a different purpose than one on a work Mac where colleagues regularly pass by
• Battery vs. plugged in — on MacBooks, animated screen savers draw more power; the simpler the screen saver, the less impact on battery when unplugged

Whether the built-in options cover your needs, or whether a third-party screen saver makes sense, depends on exactly what you're working with — and what you actually want the screen saver to do.
