How to Install a Screen Saver on Mac

All macOS screen savers here are signed and notarized by an Apple Developer ID, so they install with a simple double-click — no "unverified developer" warning. The whole process takes a minute or two. Here are the detailed steps.

Installation Steps

1. 1. Download
   On any screen saver detail page, click "Download" to get a .saver.zip file (about 300 KB each — very small).
2. 2. Unzip
   Double-click the zip in your Downloads folder to extract a .saver file (e.g. BraunClock.saver). Safari may unzip it automatically.
3. 3. Double-click to install
   Double-click the .saver file. macOS asks whether to install it; choose "Install for all users" or "Install for this user only" and confirm.
4. 4. Enable in System Settings
   Open System Settings → Screen Saver (older macOS: System Preferences → Desktop & Screen Saver) and select the screen saver you just installed.

Where to Find It by macOS Version

• macOS Sonoma (14) and later: System Settings → Screen Saver
• macOS Ventura (13): System Settings → Lock Screen / Screen Saver
• macOS Monterey (12) and earlier: System Preferences → Desktop & Screen Saver → Screen Saver tab

How to Uninstall

Right-click the screen saver in the list and choose remove; or go to ~/Library/Screen Savers (per-user) or /Library/Screen Savers (all users) and delete the corresponding .saver file.

Troubleshooting

Nothing happens on double-click / can't find it? Make sure you extracted the .saver file before double-clicking, then refresh the Screen Saver list in System Settings.

Will it drain my battery? The screen savers are energy-optimized (almost no redraw when still, and automatic frame-rate reduction under heat or low power), so they stay light even when running for a long time.
