SnowMyScreen is now called Wonderfall. Version 1.2, released on the Mac App Store on November 9, 2026, is a free update for everyone who already has the app. It keeps the falling snow and adds rain, autumn leaves, spring petals and summer fireflies, decorative lights with eight scenes, snow that piles up and can be shoveled away, optional local weather matching and easier custom image import.
SnowMyScreen started as a small app that let it snow on the desktop. Over the past year it grew into something for every season, so it got a new name and a new icon. The App Store listing is now called “Wonderfall: Desktop Effects”. Your purchase, your settings and your imported images carry over.
Why SnowMyScreen became Wonderfall
The old name promised snow and nothing else. Version 1.2 also brings rain, leaves, petals, fireflies and lights, so the app needed a name that fits all year. Wonderfall keeps the idea of something falling across your screen. The website moved to getwonderfall.com, and the App Store page stays the same.
More winter: snow that piles up
Snow can now settle along the bottom of the screen and slowly build a drift. Turn on Snow accumulation under More effects, and when the drift gets deep, pick up the Shovel and dig it out, or clear it all at once. Snow also has ten flake shapes, three presets (Gentle, Balanced, Intense) and full control over intensity, size, speed, wind and drifting.
Decorative lights for Christmas and beyond
A string of lights can hang along the menu bar, the Dock or both. Eight scenes set the mood in one click: Winter Night, Cozy Evening, Holiday Lights, New Year, Celebration, Spring Bloom, Halloween and Spooky Night. Each one can be changed: twelve palettes, twenty bulb shapes from classic ovals to gifts, pine trees and the digits of 2027, and ten patterns from a steady glow to twinkle, chase and candlelight. Here is the full lights guide.
Lights and weather now have separate display layers. Keep the snow behind your windows and the lights on top, or the other way around.
Five seasons, each with its own settings
- Snow for winter, with snow banks and a shovel.
- Rain, from drizzle to shower, with raindrops on the glass and a squeegee.
- Autumn leaves, which can gather in piles you sweep with a broom.
- Spring petals, with petal piles and the same broom.
- Summer fireflies, soft glowing points for warm evenings.
Each season remembers its own settings, so switching between them does not undo your tuning.
Match the weather outside
Turn on Match local weather, and Wonderfall uses Apple Weather to choose the effect: snow when it snows, rain when it rains, and a seasonal effect on dry days. It checks every 30 minutes. The app asks for location only when you turn this on, and every manual setting still works without it.
Your own images, with less effort
Choose Your image and add up to ten pictures at once from a file picker or by dragging them in. Common image formats and SVG work, and Wonderfall handles the sizing. Each image can fall like snow, tumble like leaves or drop like rain.
Everything else in 1.2
- Fifteen interface languages, including Ukrainian, German, French, Spanish, Japanese and Chinese.
- A new renderer built on Metal, with an automatic fallback.
- A lower frame rate in Low Power Mode or when the Mac gets hot.
- Refreshed scene previews and cleaner settings.
Wonderfall needs macOS 14.6 or later and runs on Apple silicon and Intel Macs. It needs no account and shows no ads. Ready for December? Here is how to give your Mac a Christmas theme.
