What WIE is

WIE runs Windows PE64 user-mode binaries on macOS Apple Silicon without requiring Windows, Wine or a virtual machine. Guest x86-64 code runs through a Cranelift block JIT, while Windows API calls are handled on the Mac host in Rust. Windows GUI apps can open real macOS windows, use controls, menus and native dialogs, and support printing. Guest files are accessible as files on the Mac. By default, the guest C: drive maps to a per-user app-data bottle; native Open and Save panels can access files elsewhere on the Mac.

WIE is an experimental project, and its Windows API coverage is intentionally incomplete. Reported working examples include Windows Notepad, 7-Zip console operations, console apps, and the 2048 and Snake terminal games. The D3D9 software renderer supports selected features such as VS 2.0 and PS 2.0, with 51 of 119 IDirect3DDevice9 methods implemented. Networking through WS2_32, OpenGL, child-process creation, audio output and D3D11 are among the listed missing or unsupported capabilities. The project says 32-bit binaries and full Windows compatibility are out of scope. It is free and licensed under GNU Lesser General Public License v3.0. The README documents building with Cargo or installing a prebuilt binary with Homebrew; release binaries are also published as GitHub release assets.

Who it suits

WIE suits people using Apple Silicon Macs who want to run selected Windows PE64 user-mode programs without a Windows installation or virtual machine. It may fit developers and researchers exploring emulation and cross operating system runtimes, provided the experimental status and incomplete Windows API support suit their needs.

What it does well

Runs Windows PE64 user-mode binaries on Apple Silicon Macs.
Windows GUI apps can use macOS windows and native dialogs.
Guest files are accessible as Mac files.
Supports prefix management.
Free software under the GNU Lesser General Public License v3.0.

What to know first

The project is experimental and Windows API support is incomplete.
32-bit binaries and full Windows compatibility are out of scope.
Networking, audio output, OpenGL and D3D11 are listed as missing or unsupported.
Graphics acceleration is none.

Limits

WIE's Windows API surface is intentionally incomplete, and the project does not target 32-bit binaries or full Windows compatibility. Networking handlers, OpenGL, child-process creation, audio output and D3D11 are listed as missing or unsupported.

Getting started

Visit the WIE GitHub repository.
Install a prebuilt binary with Homebrew, or build from source with Cargo.
Alternatively, download a release binary from the GitHub releases page.
Run a supported Windows PE64 user-mode binary on macOS Apple Silicon.
Use the default per-user app-data bottle for guest C: files, or native Open and Save panels to reach other Mac files.

Verdict

Choose WIE if you have an Apple Silicon Mac and want to run the Windows PE64 programs that its current implementation supports. Its native macOS windows, dialogs and file access are useful for supported GUI apps. Look elsewhere if you need broad Windows compatibility, 32-bit program support, networking or audio output.
