How to transfer your Wallpaper Engine library to Mac

A screen-by-screen walkthrough of moving your existing Wallpaper Engine scene library from a Windows PC to a Mac, over local Wi-Fi, with a free companion app and a 4-character pairing code. No cloud, no account, no re-purchase.

TL;DR

Vivid Walls ships a free Windows companion app that transfers an existing Wallpaper Engine library to a Mac over local Wi-Fi using a 4-character pairing code, no cloud upload, no account, no re-purchase. The whole process, from install to first wallpaper applied, typically takes about ten minutes.

We also wrote this up as a step-by-step walkthrough of the whole transfer, covering what to have ready before you start, the local network transfer itself, and what to check when a scene does not show up on the Mac.

What you'll need

  • An Apple Silicon Mac (M1 or later) running macOS 14.0 (Sonoma) or later, with Vivid Walls installed from the Mac App Store.
  • A Windows PC with your existing Wallpaper Engine library on it, Steam Workshop subscriptions and all.
  • Both devices connected to the same Wi-Fi network. Home networks work reliably; some public or guest networks block the local discovery this relies on.

The whole process, install to first wallpaper applied, usually takes about ten minutes. Nothing is uploaded anywhere: the transfer runs directly between your Mac and PC over your own network.

Step by step

01
Install Vivid Walls on your Mac

Open the Mac App Store listing, buy it once ($9.99, no subscription), and launch it. Grant Screen Recording permission if macOS asks, it's used to render the wallpaper behind your desktop icons.

02
Download the Companion app on your PC

On the Windows machine that has your Wallpaper Engine library, go to vividwalls.app and download the free Vivid Walls Companion (.exe). Windows SmartScreen may flag it as unrecognized since it's a small independent app, click More info, then Run anyway.

03
Put both devices on the same Wi-Fi

The Companion finds your Mac using local Bonjour / mDNS discovery. Connect both the Mac and the PC to the same Wi-Fi network before continuing. If they're on separate networks (one on Wi-Fi, one on Ethernet through a different router, or a VPN active on either), pairing won't find the other device.

04
Pair with the 4-character code

Launch the Companion app on your PC. It auto-detects your Wallpaper Engine library and shows a 4-character code on screen. On your Mac, press Cmd+Shift+P (or choose "Import from PC" from the menu), then type that code in. This establishes a direct, secure connection between the two devices.

05
Choose what to transfer

Select individual scenes, or hit Import All to bring your whole library across. A progress bar tracks each file. Most libraries, even a few hundred scenes, finish in a handful of minutes on a normal home connection; very large libraries or slower Wi-Fi will take longer.

06
Apply a wallpaper

Your imported scenes show up in the Vivid Walls library grid on your Mac right away. Click any one and it becomes your live desktop background instantly, no restart needed.

Troubleshooting

The Mac and PC can't find each other

This is almost always a network issue rather than an app issue. Confirm both devices show the same Wi-Fi network name. Some routers isolate wireless clients from each other for security ("AP isolation" or "client isolation"), which blocks the local discovery this relies on, check your router's settings if you control it, or try a personal hotspot as a workaround on unfamiliar networks (a coffee shop or office Wi-Fi, for example). A VPN active on either device can also interfere; disconnect it and try again.

Windows SmartScreen won't let the Companion run

This is expected for a smaller independent app that hasn't built up SmartScreen's reputation database yet. Click More info, then Run anyway. The download link only ever comes from vividwalls.app.

The transfer is slow

Transfer speed depends on your Wi-Fi, not on Vivid Walls. Moving both devices closer to the router, or connecting the PC via Ethernet if possible, speeds things up noticeably for large libraries.

Some scenes didn't come through, or don't render correctly

Scene format coverage is where the most active development happens, since the Workshop catalog spans years of scenes with different styles and complexity. If something is missing or renders wrong after import, send the scene name or Workshop link to support@vividwalls.app, reported scenes get looked at directly and patched in updates.

What transfers, and what to expect

Vivid Walls plays the Wallpaper Engine scene format natively (particle effects, visual effects, animated characters), and also plays video, web, and GIF wallpapers. It does not claim every single wallpaper in every library renders identically to Windows on day one, scene format support is broad but still actively expanding. What does transfer is the actual file: nothing is re-encoded, re-compressed, or altered in transit, and nothing is stored anywhere except on your own Mac and PC. For the bigger picture of running Wallpaper Engine on Mac, including where scene support still falls short, see the full answer page.

A sense of proportion helps for setting expectations before you import. Filtering the Steam Workshop by wallpaper type gives 1,561,362 scene items, 1,187,365 video items, and 101,223 web items, out of 2,865,391 published in total. Scene and video are the two formats most libraries are built from; web wallpapers, the format with the most gaps on macOS today, are the smallest of the three by a wide margin. Those are counts of Wallpaper Engine's catalog, not a measurement of how much of it renders correctly on a Mac, which is not a number anyone has published. Your Steam Workshop subscriptions also stay exactly where they are: the transfer copies files to your Mac and changes nothing on your Steam account.
