How to use Wallpaper Engine wallpapers on Mac (Vivid Walls)

Wallpaper Engine isn't available on macOS, and it never has been. A third-party app called Vivid Walls now offers a real Wallpaper Engine for Mac workaround: it imports many Wallpaper Engine scene files and renders them natively using Apple's Metal graphics technology, with no Windows, Wine, or virtual machine involved, according to developer James Goodnight (AppleInsider, today). That's the answer to how to use Wallpaper Engine wallpapers on Mac right now, and it holds up for the scene type AppleInsider actually tested.

AppleInsider ran a hands-on check by importing a wallpaper folder called "Fishing Frogs by Abi Toads," which contained a project.json file, a preview GIF, and a one-minute, 3840-by-2160 MP4 (AppleInsider, today). Vivid Walls flagged the folder as compatible, and once applied, the video animated on the Mac desktop. That confirms a working video-based wallpaper, nothing more. Goodnight says the app doesn't support scenes built on 3D models or wallpapers packaged as Windows executables at all, and web wallpapers only get partial support (AppleInsider, today). Interactive, particle-heavy, and SceneScript-driven scenes weren't part of AppleInsider's test, so how faithfully Vivid Walls reproduces those remains independently unverified.

This guide covers both ways to run Wallpaper Engine on Mac through Vivid Walls: importing a single wallpaper folder to test compatibility, and pulling an entire Steam library over the network with the app's Windows Companion tool. It also covers what to check on battery and privacy, an optional lock-screen export feature, and what to confirm before paying for the app.

What you need before starting

The two import paths have different requirements, so check which one applies before buying anything.

• A Mac running macOS 14 Sonoma or later. Goodnight says the app is optimized for Apple Silicon (Vivid Walls, earlier this year).
• Vivid Walls purchased from the Mac App Store. At the time of AppleInsider's report, the U.S. listing priced it at $9.99 as a one-time purchase (AppleInsider, today).
• For a full library transfer only: a Windows PC with Wallpaper Engine and Steam installed, plus both machines on the same local network. Home Wi-Fi or Ethernet both work for this (Vivid Walls, earlier this year).

Pricing may shift soon. Goodnight told AppleInsider he plans to release an update making Vivid Walls a free download with a three-day trial of every feature, while keeping the $9.99 unlock price and preserving access for anyone who already bought it (AppleInsider, today). That trial wasn't live as of this report, so check the current listing on Vivid Walls' site or the Mac App Store before buying, rather than assuming a free trial is already there.

Folder import doesn't require the Windows Companion tool or a Steam library on a PC at all. It just requires an actual Wallpaper Engine wallpaper folder from a library already owned.

How to use Wallpaper Engine wallpapers on Mac through Vivid Walls

Import a single wallpaper folder first

Start with one folder before attempting a full library transfer. It's a faster way to see whether a given wallpaper works before committing an entire collection to it.

1. Locate a Wallpaper Engine wallpaper folder from a library already owned. AppleInsider's test folder included a project.json file, a preview image, and a video file, though that describes the folder tested, not a documented list of what Vivid Walls requires for every import (AppleInsider, today).
2. Import that folder into Vivid Walls. The app checks compatibility on its own and reports success or failure, the same behavior AppleInsider saw with the 4K MP4 folder that imported and animated correctly (AppleInsider, today).
3. Apply the wallpaper to the desktop, then run through a quick check: confirm it's animating, test pointer interaction if the scene is supposed to support it, and only test sound reactivity after granting the audio permission Vivid Walls requests. Compare behavior on AC power versus battery, since frame rate can change between the two.

If playback stutters, freezes, or shows visible artifacts after that check, it may indicate the scene includes elements Vivid Walls doesn't fully support yet, though other causes are possible too. Try a second, simpler video-based wallpaper for comparison before assuming the app itself is at fault.

Transfer a full library with Windows Companion

Use this path once a folder import has worked, since it moves an entire Steam library at once. The Vivid Walls Wallpaper Engine import process for a full library runs through a small free companion app on the Windows PC.

1. Install the free Windows Companion app on the Windows PC. It scans common Steam library folders automatically and reports how many wallpapers it found (Vivid Walls, earlier this year).
2. If it reports zero wallpapers, check whether the Wallpaper Engine library sits on a non-default drive. Companion scans common, default folders on its own, so a library stored elsewhere may not turn up (Vivid Walls, earlier this year).
3. On the Mac, open Vivid Walls and press Cmd+Shift+P to launch the Import from PC wizard. It searches the local network for Companion using Bonjour (Vivid Walls, earlier this year).
4. When Companion shows up, enter the 4-character pairing code displayed on the PC. A new code generates every session, confirming the connection lands on the intended machine rather than another device on a shared network (Vivid Walls, earlier this year).
5. Leave Companion running on the PC while the transfer happens. Wallpapers populate the Vivid Walls library on the Mac as they arrive, so browsing can start before the whole library finishes copying (Vivid Walls, earlier this year).
6. Once the transfer finishes, click Apply to Desktop on any wallpaper to start rendering it. Volume, speed, fill mode, and opacity save per wallpaper and persist across reboots (Vivid Walls, earlier this year).

If the PC doesn't appear

Give it about 30 seconds. If nothing shows, the two machines are likely on different network segments, since Bonjour's local multicast doesn't cross subnets (Vivid Walls, earlier this year). Connecting both devices to the same Ethernet switch is the usual fix, even though Wi-Fi normally works fine for this transfer. A manual IP entry is available as a fallback if Bonjour discovery keeps failing (Vivid Walls, earlier this year).

Test every imported scene before trusting it

A successful import only means Vivid Walls accepted the files as compatible, not that every effect inside the scene will display the way it did in Wallpaper Engine. A collection can contain files the app accepts but doesn't render correctly (AppleInsider, today).

Goodnight's compatibility list for using Wallpaper Engine files on macOS includes custom visual effects, particles, character animation, pointer interaction, and sound-reactive audio behavior, plus partial support for SceneScript, Wallpaper Engine's scripting layer for custom behavior, which he says isn't complete yet (AppleInsider, today). Scenes built around 3D models or packaged as Windows executables aren't supported at all, web wallpapers get only partial support, and scenes that stack several complex effects together can render incorrectly (AppleInsider, today).

Vivid Walls' own developer guide frames the gap differently, claiming the app handles the vast majority of scenes correctly, with only a small percentage running into shader constructs or SceneScript features that aren't fully built out, and that those gaps usually get patched quickly (Vivid Walls, earlier this year). That's a company claim, not something independently verified across a broad set of scenes. Check each imported wallpaper individually after applying it, especially anything beyond a simple looping video, rather than assuming one successful import means the rest of a library will behave the same way.

Battery, performance, and privacy permissions to check

AppleInsider's performance check covered one of Vivid Walls' bundled 1080p videos rather than the imported 4K wallpaper, so treat these numbers as a general baseline for animated Wallpaper Engine backgrounds on Mac, not a guarantee for every scene. Activity Monitor showed roughly 5.5% to 7.4% CPU use across repeated samples, close to the 5.8% to 7% Vivid Walls' own dashboard reported, with memory use between about 91MB and 124MB (AppleInsider, today). On battery, Activity Monitor logged an Energy Impact of about 6.8, a relative measure of current energy draw as Apple defines it (AppleInsider, today).

Vivid Walls builds in a few power safeguards worth knowing before leaving it running all day. The test Mac showed a 30 fps cap, a drop to 15 fps on battery, and automatic pausing after 15 minutes of inactivity (AppleInsider, today). Goodnight says the app also pauses when the desktop is fully covered or another app goes full screen, supports Low Power Mode, and can reduce frame rate under thermal pressure (AppleInsider, today). On a multi-monitor setup, that covered-window pause rule only triggers once every wallpaper window is covered, so a wallpaper can keep running on a hidden display if another screen is still visible (AppleInsider, today). Anyone who wants tighter control can head into Settings, then Performance, and manually force a 15 fps cap or a full pause on battery power (Vivid Walls, earlier this year).

Permissions matter most for sound-reactive wallpapers. Depending on the macOS version, expect a Screen Recording prompt on macOS 14.0 and 14.1, or an audio capture prompt on 14.2 and later (AppleInsider, today). Goodnight says the app only captures system audio, never the microphone, consistent with its stated privacy policy, and that declining the prompt just disables sound reactivity without breaking normal playback (AppleInsider, today). A separate Automation permission lets music-reactive widgets read Now Playing data from Apple Music or Spotify; turning it down just removes album artwork rather than breaking the widget (AppleInsider, today). The privacy policy also states that captured audio processes locally without being stored or transmitted, and that the app collects no personal data, analytics, telemetry, or crash reports (AppleInsider, today).

Optional: export a wallpaper to the Mac lock screen

This is a separate export workflow from the desktop-wallpaper import path above, and it's worth understanding before turning it on. Vivid Walls can export a wallpaper as a 4K HEVC video and add it directly to the catalog macOS uses for its built-in aerial wallpapers, since Apple doesn't provide a documented interface for this kind of integration (AppleInsider, today).

Because it edits that catalog directly rather than going through a documented API, a future macOS update could change how the feature behaves. A Remove button in the export sheet deletes the exported video and its catalog entry, though that's a manual cleanup step rather than a fix for compatibility problems a macOS update might introduce (AppleInsider, today). Once a wallpaper is exported, macOS handles playback on its own without Vivid Walls needing to stay open (AppleInsider, today). Granting Automation permission lets the app refresh the lock screen automatically right after export; without it, the new wallpaper shows up after the next login instead (AppleInsider, today).

What to do next

Vivid Walls gives Mac owners a practical way to run Wallpaper Engine on Mac without touching Windows, but the independent proof so far covers one straightforward video wallpaper, not the full range of what Wallpaper Engine's workshop offers. Check the live price and trial terms on the Mac App Store first, since the free-trial version wasn't confirmed as available as of this report.

Import one simple, video-based wallpaper folder and confirm it plays smoothly, check its CPU and battery behavior in Activity Monitor, and make sure it isn't asking for permissions that feel out of place. If that wallpaper behaves the way it's supposed to, move on to the Windows Companion transfer for a full library. If it relies heavily on particles, 3D models, or SceneScript behavior, hold off on committing a whole library until Vivid Walls' support for those categories gets wider independent testing.
