That's the whole idea.
This page is snowing the way your Mac will. Grab any title bar and shake the snow off.
Make It SnowLet it pile up on everything.
Real snow for your whole Mac. It settles on your windows, slides off when you move them, grows icicles, and builds its own snowmen on the Dock.
Download for MacmacOS 14 or newer, Apple silicon. One extra step to open it.
It knows where your windows are.
Snow lands on your windows
It drifts along their top edges, even around the ones in front. Drag a window and it all slides off, landing on whatever is below.
Icicles grow while you work
They form slowly along bottom edges and drip. Move the window and they snap off and shatter.
Snowmen build themselves
Now and then one rolls itself together on the Dock or a deep drift. It watches your cursor, waves when you get close, and eventually melts.
Your cursor joins in
Push flakes around, plow through drifts, wipe frost off the corners. Rest it and a little cap of snow builds up. Shake it and the whole screen goes snow globe.
In front, behind, or fullscreen
Snow can fall over your windows or behind them, on every Space. It can show over fullscreen apps, or stay out of the way of them.
Weather, in 2D or 3D
Switch between crisp flat flakes and tumbling 3D ones. Calm spells and blizzards come and go, and a sleigh flies by if you wait long enough.
Your lid changes the snow
MacBooks have a lid angle sensor, and Make It Snow reads it where it can. Lean it all the way back and snow slows to a drift. Tip it forward and the piles slide off. Move it quickly and everything gets knocked loose.

Getting it open takes one extra step.
- Download it, unzip it, and drag Make It Snow to Applications.
- Open it. macOS will say it can't verify the developer, and refuse.
- Go to System Settings → Privacy & Security, scroll down, and click Open Anyway.
- Look for the snowflake in your menu bar. That's where every setting lives.
You only do this once. It also opens at login, which you can turn off in the menu.
Fair questions.
Apple shows it for any app that isn't signed with a paid Apple Developer ID, and this one isn't. It doesn't mean something was found wrong with the app, but it does mean Apple hasn't checked it, so only open it if you trust where you got it.
It reads where your windows are, but not what's in them, and doesn't need Screen Recording. The app has no accounts or analytics, and it only goes online to check this site for updates. Accessibility access is optional and only makes the Dock's position exact.
It's built in Metal to stay light. On an M3 MacBook Air it used about 5% CPU on battery at 30fps, and about 9% at 60fps. macOS also does extra work to draw over the whole screen, so a power saver switches on by default when you're on battery.
Every update is signed, and the app refuses any file whose signature doesn't match. You can turn automatic updates off in the menu.
