Getting real falling snow on a Mac desktop

macOS has no falling-snow effect: the aerials in Wallpaper settings, snowy peaks included, only move as you lock or unlock your Mac. For snow that keeps falling, add an overlay app such as Snowy, loop a free snowfall clip with a live-wallpaper app, or pick a GPU-rendered scene like Mac+ Snow.

macOS has no falling-snow effect built in: even Apple's snowiest aerial wallpapers only animate for a moment, as you lock or unlock the Mac, then hold still while you work. Search “snow live wallpaper mac” and page one is mostly download galleries, with no guide in sight. For snow that keeps drifting on a real desktop, there are exactly three honest routes — an overlay app, your own snowfall clip, or a GPU-rendered scene like Mac+ Snow — compared below alongside the aerial and screen-saver options Apple already ships.

What macOS gives you in winter: aerials that move only when you lock or unlock

Open System Settings, click Wallpaper, and Apple's own wallpaper guide lists the categories on offer, among them Dynamic Wallpapers, images that “brighten and darken, based on the time of day”; Landscape, Cityscape, Underwater, and Earth aerials; Shuffle Aerials, still images that change at an interval you set; and Your Photos. None of them is a snowfall effect.

The aerials are the closest thing to motion Apple ships, and Apple is specific about when that motion happens: “These aerial images animate as you lock or unlock your Mac.” A community-maintained catalog of Sonoma and Sequoia aerial names lists flights over snow-covered peaks in Iceland and near Yosemite, and over glaciers in Greenland — real snow, filmed from the air, but panning scenery rather than falling flakes. No version of that catalog documents an actual snowfall effect, though it stops at Sequoia and can't speak for whatever Tahoe or macOS 27 may have added since.

One more detail matters for what comes next: “By default, the aerial wallpaper you select is also used as your screen saver.” Whichever snowy aerial you pick here follows you into the next section.

Snow as a screen saver: the slow-motion aerial, and why the old snow savers are gone

Click Screen Saver in the same settings, and Apple's screen saver guide reuses the same aerials: “These slow-motion images show dramatic views.” Choose Custom — Apple's own instruction is “Select Custom, then choose a screen saver…” — and pick a snowy one, or leave the default, since your aerial wallpaper already doubles as the screen saver. Either way, this is the closest native macOS gets to a snow screen saver: dramatic, slow, and on screen only while the Mac is idle — never while you're working.

Search “snow screensaver mac” and some of the oldest results are the most literal match for the query, and the least usable one. OSXDaily's writeup of Snowfall describes “a beautiful screensaver of falling three dimensional snowflakes,” then adds the detail that matters most today: it “requires Tiger (10.4) to Snow Leopard (10.6)” — Mac OS X versions, long before today's macOS. A page still ranking in 2026 doesn't mean the app still installs in 2026; check what a result actually requires before trusting it.

Snow falling over your desktop today: two overlay apps that keep moving while you work

Snowy! is free and “requires macOS 15.6 or later.” Its listing describes “a delightful menu bar app that adds falling snow and festive holiday lights to your desktop,” with intensity you can adjust “from a light flurry to a full blizzard” and a choice to “have snow fall in front of or behind your windows.” Holiday-light themes — Multicolor, Warm White, Candy Cane, Blue, Rainbow — come along for the season.

Let It Snow is older and paid: $1.99 plus in-app purchases, and it “requires macOS 10.14 or later.” Its own description promises “realistic snow fall,” “random snow flurries” and “gusts of snow,” with a “snow behind active window” setting and a Pro unlock for a permanent snow drift and multi-display support. One line is worth repeating exactly, because it corrects an easy assumption: “Wallpaper not included with app” — Let It Snow draws snow over your existing desktop picture, it doesn't supply one.

Neither listing documents its own battery or GPU impact, so if that matters to you, watch Activity Monitor for a while after installing either one.

Your own snowfall video as a live wallpaper

If neither overlay app matches the look you're after, the next option is a looping snowfall clip of your own, played by a live-wallpaper app instead of drawn as an overlay. Pexels is a solid free source: “All photos and videos on Pexels are free to use,” and “attribution is not required.” Its license does draw one hard line worth knowing before you search for a “snow falling” stock clip: don't “redistribute or sell the photos and videos on other stock photo or wallpaper platforms.” Download a clip to use on your own Mac; don't re-upload it as someone else's wallpaper file. Pixabay and Coverr are worth checking too, each with its own free license — read it, since the exact restrictions differ from Pexels'.

For the mechanics of actually looping the file, our guide to setting a video as wallpaper on Mac covers it end to end. One native-adjacent option worth knowing about: Aerial, a free, open-source screen saver whose own site says, “Drop any .mov or .mp4 into a single folder and Aerial picks it up.” In its Beta, Aerial also “registers as a native wallpaper” inside System Settings, “like any built-in one” — a real step forward, but still labeled Beta, and it needs macOS 26 or later.

The Mac+ Snow scene: GPU-rendered flakes behind your icons

Mac+ takes a third approach: a scene rendered live by the GPU, not an overlay drawn over your windows, and not a loop of photographic snow footage. Snow is one of 15 animated scenes in the app, and its own subtitle for this one is simple: “Drifting flakes.” Apply one of its color palettes to recolor the scene instantly, or swap in your own video or a still image as the background instead — looping your own video is a Pro feature; a still image is available on the free tier.

Performance is adjustable rather than fixed: 30, 60 or 120 FPS, adjustable render resolution, and an automatic pause “when the screen sleeps or an app covers it” — full-screen apps included, so nothing keeps rendering behind something you can't see anyway. Mac+ runs across every display you enable it on, updates automatically when you plug in a new one, and needs no account: rendering is 100% local, with no ads or telemetry. It supports macOS 13 Ventura or later, on Apple Silicon and Intel, and is made in France by PENRA.

The free tier includes 6 of the app's 15 animated scenes (the site doesn't say which), 8 color palettes, an image background, 6 folder icons, 2 widgets and multi-display support; Pro unlocks the rest for €9.99 once or €1.99 a month with a 7-day trial. Two limits worth stating plainly: a Mac+ scene always stays behind your windows, unlike Snowy or Let It Snow, so it never draws over what you're working on; and Mac+ has no Lock Screen or screen-saver mode, so a scene you pick for the desktop stays on the desktop.

Which snow option fits your Mac

Five rows, one honest table. “Moves while you work?” is the column that matters most if you searched for something that keeps falling, not a still picture.

If you only remember one row, make it the second: an overlay app is the only route here that can put snow in front of your open windows, not just behind them.

Make it snow on your Mac desktop

1. Open System Settings, click Wallpaper, and choose a snowy aerial — it animates only as you lock or unlock your Mac.
2. Click Screen Saver, choose Custom, and pick the same aerial — or keep the default, since Apple already uses your aerial wallpaper as the screen saver.
3. For snow that keeps falling while you work, install an overlay app such as Snowy (free) and choose to show the snow behind your windows.
4. For your own look, download a looping snowfall clip from Pexels, Pixabay or Coverr — read the license first — and play it with a live-wallpaper app.
5. Or open Mac+ from the menu bar and choose the Snow scene and a palette.

macOS 13 Ventura or later. Apple Silicon and Intel. Free tier: 6 scenes, 8 palettes, image background; your own video is Pro.
