A Wine bottle is a self-contained Windows environment that lives inside macOS — it has its own virtual C: drive, registry, and set of Windows libraries, completely isolated from the rest of your system. MoltenVR uses a bottle to run Windows VR games without a separate Windows PC, then streams every rendered frame to your headset in real time.Documentation Index

How MoltenVR’s bottle works
Inside the bottle, two critical components are installed and configured by the setup wizard:- DXMT — translates Direct3D 11 draw calls into Apple Metal API calls, so the game’s GPU work runs fully native on your Apple Silicon chip rather than through a software emulation path.
- OpenXR VR runtime — a custom runtime that intercepts every VR frame the game submits and hands it to MoltenVR’s streaming pipeline. Games call this runtime for head tracking, controller input, and haptics, just as they would call SteamVR on Windows.
Managed bottle vs. custom bottle
- Managed Bottle (Recommended)
- Custom Bottle (Existing Install)
MoltenVR’s built-in bottle manager uses WhiskyWine / GPTK under the hood — the same proven Wine build that powers the frankea Whisky fork. The setup wizard handles everything: it creates and configures the bottle, installs the DXMT graphics layer (Direct3D 11 → Metal translation), and registers the OpenXR runtime, each in a single click.Once the wizard completes, the managed bottle is fully configured and ready to run VR games. No manual Wine tweaking is needed.
The Minecraft exception
Minecraft + Vivecraft runs fully native on macOS — no Wine bottle involved at all. MoltenVR launches it through Prism Launcher and Vivecraft handles the VR integration directly. It is the first working Mac Minecraft VR experience since SteamVR for Mac was discontinued in 2020.
