Winter snow
Choose an effect to preview. Your own wallpaper stays just as it is.
Six ways to set the scene
More than a snow day.
Choose a seasonal effect, or bring your own artwork. Change the intensity, size, speed and wind to find a look that feels right.
Rain
From a light drizzle to a steady shower. Tune the wind, drop size and intensity.
Autumn leaves
Amber and crimson leaves tumble across your desktop with a breeze you control.
Spring petals
Blush-colored petals float through your workspace for a softer change of season.
Summer fireflies
Warm points of light wander across the screen, bringing a summer evening indoors.
Your own images
Import PNG artwork and let it fall like snow, tumble like leaves or move like rain.
Small details. Your atmosphere.
Make it feel like your desktop.
Keep your wallpaper
The effects are transparent overlays. Keep the desktop background you already love.
Choose where it appears
Show the animation over open windows or on the desktop behind them. Use the full screen or a 150-point strip at the top.
Tune the motion
Adjust intensity, particle size, speed and wind. Snow, leaves and petals also have drifting controls.
Add a little light
Decorate the menu bar, Dock or both with garlands. Pick colors, bulb shapes and steady, twinkle, wave or chase animation.
Make it your own
Add up to 10 PNG images, select or mix them and choose a motion style. Transparent backgrounds work best.
Stay in your flow
Click through the overlays to use your Mac. Control the effects from the menu bar and optionally launch at login.
A change of season in three steps.
Install and open
Download the Mac app and find its icon in the menu bar.
Choose your effect
Open settings, enable Weather effects and choose snow, rain, leaves, petals, fireflies or custom images.
Find your balance
Adjust motion and placement. Add lights, or keep it subtle with a desktop-only effect.
What is SnowMyScreen?
SnowMyScreen is a macOS menu bar app that adds animated effects to your desktop: snow, rain, autumn leaves, spring petals, summer fireflies and custom PNG images. It also includes decorative lights for the menu bar and Dock.
Is it a live wallpaper or a screensaver?
It is a desktop overlay. Your existing wallpaper stays in place, and the animation can appear behind or over open windows while you use your Mac. It does not replace the macOS screensaver.
Does it work with multiple displays?
Yes. The app creates an overlay for each connected screen and updates the overlays when the display setup changes.
Can I still click my apps and desktop?
Yes. The overlay windows ignore mouse events, so you can click through them and use your Mac normally. Desktop only mode places the effects behind your windows.
Can I use my own images?
Yes. Import up to 10 PNG images, each up to 5 MB and 1024 × 1024 pixels. Choose one or mix several. Custom images can move like snow, leaves or rain.
Can I add Christmas lights without snowfall?
Yes. Weather effects and garlands have separate controls. Put lights on the menu bar, Dock or both, and choose a palette, shape and animation.
Does the rain effect include sound?
The current app provides visual effects. It does not include rain audio, music, weather forecasts or a live weather feed.
Which Macs are supported?
The app target requires macOS 14.6 or later. Check the current Mac App Store listing for the requirements of the available release before downloading. It is a Mac app, not an iPhone or iPad app.
Does it need an internet connection?
Effects, settings and custom images work locally on your Mac. Downloading or updating through the Mac App Store requires internet access.
How do I turn the effects off?
Use the menu bar controls to disable weather effects or lights, or quit the app. Launch-at-login behavior is a separate setting.
