Pre-release prototype · not downloadable yet

The bridge to everything.

Zenbashi is a free, open-source Mac app built to run your Windows Steam games on Apple Silicon, so you never have to touch the engine underneath.

Honest status: Steam runs and the first game tests are under way. Nothing is ready to download.

What it is

Your Steam library, on your Mac. No installs to learn, no settings to guess, and no price tag. Zenbashi is built to bring a patched Wine engine and Apple's D3DMetal graphics together behind one friendly window.

How it works

Three steps, then play.

That is the design goal. Here is how it is meant to feel.

Sign in to Steam

Open Zenbashi and sign in. Your library shows up, and Steam keeps doing the downloading and updating.

Pick a game

Zenbashi is designed to choose settings for your chip from its compatibility database, and to try safe fallbacks if something fails to start.

Press Play

Graphics are meant to run through Apple's D3DMetal. If a change breaks something, a snapshot lets you step back.

Features

Built for people who just want to play.

These are the things Zenbashi is built to do. Not all of it has been verified end to end, and the badges mark what is still in development.

Steam mode

Sign in to the Windows Steam client inside Zenbashi and use your library the way you already do. You keep your games, your friends and your saves.

D3DMetal graphics

DirectX 11 and 12 games are translated to Metal using Apple's D3DMetal, shipped with Apple's notices. It needs Apple Silicon.

Compatibility by chip

A database that will record how each game runs on each Apple chip family, so you are not guessing.

In development

External disks

Keep big libraries on an external drive and keep your Mac's storage free.

In development

Snapshots

Save a game environment before you change it, and go back if it goes wrong.

Couch mode

Sit back, grab a controller and move through the library without a keyboard or mouse.

In development

Mods

Install and manage mods for your games from one place, with the ability to undo.

In development

Accessibility

Designed for VoiceOver, keyboard control and reduced motion, because games are for everyone. Still to be verified.

In development

9 languages

The app is being localized into English, Italian, German, Spanish, French, Brazilian Portuguese, Japanese, Korean and Simplified Chinese.

In development

Honesty

Where things really stand.

Zenbashi is a young prototype. We would rather tell you this than oversell it.

What works today

  • The Steam client runs inside a Zenbashi environment.
  • Environments and snapshots exist in the app, but are not yet verified end to end.
  • A first game test is in progress.

What does not yet

  • There is no download, installer or signed release.
  • No game has been verified end to end.
  • Intel Macs are untested.
  • Games that need kernel-level anti-cheat will not run.
