Crosswire

Crosswire runs Windows games and apps on macOS by letting users install a Windows .exe and launch it from a searchable library. Each installation has a separate isolated space. During setup, it detects common Windows runtimes such as Visual C++ and .NET and offers to install them. For recognized games, it applies known-good settings automatically. Crosswire can check for and update its Windows compatibility layer, and releases arrive automatically on version 1.1.1 or later. It is free and open source under GPL-3.0, with source published on GitHub. The maker describes it for Apple Silicon Macs running macOS 14.6 or later; the base installation needs about 1 GB of free disk space. Crosswire is not Apple-notarized yet, so macOS requires users to confirm opening it in Privacy & Security. Compatibility varies by app version and macOS release. Microsoft 365 is unsupported, while League of Legends and Valorant are blocked by Vanguard.

Crosswire provides a free way to organize and launch some Windows apps and games on supported Macs. Check the app-specific limits and installation requirements before relying on it.

Crosswire is for people who want to run Windows games or apps on an Apple Silicon Mac with macOS 14.6 or later. It may suit users comfortable with app-specific compatibility limits and macOS security confirmation.

Crosswire is a free macOS utility for launching Windows apps and games on Apple Silicon Macs. It best suits users who want a searchable home for compatible .exe programs, with each install kept separate. Its automatic setup assistance is useful, but the system requirements and title-specific blocks make checking compatibility essential.

Overview

Crosswire installs Windows .exe files and adds them to a searchable library, where each program can be launched with a click. Separate isolated spaces for each install help prevent one app from interfering with another, which is helpful for people maintaining multiple Windows programs. That organization does not guarantee an app will run: compatibility varies by app version and macOS release.

The project is free and open source under GPL-3.0, with its source published on GitHub. The maker directs users to a wiki for troubleshooting and accepts bug reports and feedback by email. One setup wrinkle is that Crosswire is not Apple-notarized yet; macOS requires users to approve opening it in Privacy & Security.

Key features

Install management and runtime support

During installation, Crosswire detects common Windows runtimes such as Visual C++ and .NET and offers to install them. This can reduce manual setup for apps that depend on those components, though it does not resolve broader compatibility problems.

Game configuration and compatibility updates

For games Crosswire recognizes, it applies known-good settings automatically, a practical shortcut for supported titles. It can also check for updates to its Windows compatibility layer. From version 1.1.1 onward, releases arrive automatically, so users on those versions need not rely on manual update checks.

The limits are consequential: Microsoft 365 is unsupported, and League of Legends and Valorant are blocked by Vanguard. Crosswire is therefore a poor fit for users whose main requirement is either of those games or Microsoft 365.

Pricing

Crosswire costs nothing. Its single Crosswire plan is free and open source under GPL-3.0; there is no paid tier or free-trial decision to weigh. That makes it a low-cost option for experimenting with compatible apps, but the price does not change its hardware, operating-system, or app-compatibility limits.

Platforms

Crosswire supports macOS and Apple silicon, but requires macOS 14.6 or later and about 1 GB of free disk space for the base installation. It does not support Linux. Users on older macOS releases or Intel Macs should choose another option.

Who it's for

Crosswire is aimed at Apple Silicon Mac users on macOS 14.6 or later who want to install and organize compatible Windows apps or games. Its isolated installs, searchable library, runtime assistance, and automatic settings for recognized games make it most compelling for users who value a guided way to manage several programs. It is not the right choice for people who need Microsoft 365, League of Legends, or Valorant, or who cannot meet its system requirements.

Pros and cons

• Pros: Free and GPL-3.0 open source, so there is no purchase cost and the source is published.
• Pros: Separate app spaces and a searchable launch library help keep several installs organized.
• Pros: Runtime detection and automatic settings for recognized games can reduce setup work.
• Cons: macOS 14.6 or later and Apple Silicon are required, excluding older systems and Intel Macs.
• Cons: The app is not Apple-notarized yet, so opening it requires a Privacy & Security confirmation.
• Cons: Compatibility depends on the app version and macOS release, with Microsoft 365 unsupported and Vanguard blocking League of Legends and Valorant.

Alternatives

For another free, open-source option spanning macOS and more platforms, consider Boxedwine, which supports Linux, macOS, web, and Windows and is released under GPL. Linux users can compare WineGUI, a free Linux option, or GE-Proton, a free Linux gaming compatibility tool that requires compatible Vulkan drivers and packages.

Mac users who want a freemium alternative can look at MacWrap, whose free tier covers wrapping your own software and generic compatibility analysis. PlayOnLinux and Q4Wine are free options for Linux and macOS; PlayOnLinux notes that not every game is supported and performance can sometimes decrease, while Q4Wine is open software that is free to download and install in most cases. For a free macOS tool requiring a supported Windows program, consider PlayOnMac; Porting Kit installs Windows games and apps on macOS using Wineskin. Browse Windows Compatibility Layers to compare more options.

Verdict

Choose Crosswire if you have an Apple Silicon Mac running macOS 14.6 or later and want a free, organized way to launch Windows programs that it supports. Its isolated installs and setup assistance are the strongest reasons to try it; its uneven compatibility, hard blocks for some popular software, and required macOS security confirmation are the reasons to look elsewhere when a particular app must work reliably.
