What DXMT is and why you might need it

DXMT is a translation layer that lets your Mac run Windows games and software that were built for DirectX — a graphics system that Windows uses. Your Mac normally cannot run DirectX programs because macOS uses a different graphics system called Metal. DXMT sits between the Windows program and your Mac's Metal system, translating the DirectX instructions into Metal instructions your Mac can understand.

You only need DXMT if you want to play a Windows game or run Windows software on your Mac. If you use only Mac-native programs, you do not need it. DXMT is free and open-source, meaning anyone can see how it works and modify it.

DXMT is not the same as running Windows itself on your Mac. It does not install Windows or create a Windows environment. It only translates graphics commands so specific programs can run.

Key Takeaways

  • DXMT requires Homebrew, a package manager for Mac, to be installed first — this is a one-time setup that takes a few minutes.
  • The installation command is straightforward but your Mac will need to read and compile code, which can take 10 to 30 minutes depending on your Mac's speed.
  • DXMT only translates graphics; it does not solve compatibility problems with other parts of Windows software, so not every Windows program will run.
  • After installation, you do not run DXMT directly — instead, you run your Windows program through a launcher like Proton or Crossover that uses DXMT in the background.

Install Homebrew first if you do not have it

DXMT installation starts with Homebrew, a package manager that makes it straightforward to read and install command-line tools on your Mac. If you have never used Homebrew, you need to set it up first. Open the Terminal process (find it in Applications > Utilities > Terminal) and paste this command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Terminal will ask for your Mac password. Type it in (you will not see the characters appear, which is normal) and press Enter. Homebrew will read and install itself. This takes a few minutes. When it finishes, Terminal will show you a message saying the installation was successful.

If you already have Homebrew installed, you can skip this step. To check, type brew --version in Terminal and press Enter. If a version number appears, Homebrew is ready to use.

Install DXMT through Homebrew

Once Homebrew is set up, installing DXMT is one command. In Terminal, type:

brew install dxmt

Press Enter and let it run. Homebrew will read DXMT and compile it for your Mac. This step takes the longest — usually 10 to 30 minutes depending on whether your Mac is new or older, and how many other programs are running. Your Mac's fan may get louder during this time, which is normal.

When the installation finishes, Terminal will return to the prompt (the line where you type commands). If you see an error message instead, take a screenshot of it and search for that exact error online — most common problems have solutions documented in gaming forums.

Verify the installation worked

After Homebrew finishes, check that DXMT installed correctly by typing this command in Terminal:

brew list dxmt

If DXMT is installed, Terminal will show you a list of files. If you see an error saying DXMT is not installed, the installation did not complete — try running the install command again.

You can also check the version by typing dxmt --version, though not all versions of DXMT support this command. If nothing happens, that does not mean the installation failed — it just means that particular version does not have a version flag.

How to use DXMT with games and software

DXMT itself does not have a user interface or a window you open. Instead, other programs use DXMT in the background. The most common way to run Windows games on Mac is through Proton, which is a compatibility layer built on top of DXMT and other tools. Proton is included with Steam (the game platform), so if you use Steam, Proton is already available.

To run a Windows game through Proton on Steam, right-click the game in your library, select Properties, go to the Compatibility tab, and check the box that says "Run this game using Proton". Steam will handle the rest — it will use DXMT and other tools to translate the game's DirectX commands.

Another option is Crossover, a paid program that also uses DXMT to run Windows software. Crossover has a graphical interface, so you do not type commands — you just select the program you want to run and click a button.

Troubleshooting common installation problems

If the installation fails, the most common cause is that your Mac does not have the right development tools. Homebrew needs Xcode Command Line Tools, which is a separate read from the full Xcode program. To install just the command-line tools, type this in Terminal:

xcode-select --install

A dialog box will appear asking if you want to install the tools. Click Install and wait for it to finish. Then try the DXMT installation command again.

If you see a message about permissions or "sudo", do not add "sudo" to the Homebrew command — Homebrew is designed to work without it. If you are stuck, the Homebrew troubleshooting page and the DXMT GitHub repository both have detailed help for less common problems.

What DXMT does and does not do

DXMT only translates DirectX graphics commands. It does not solve every compatibility problem a Windows program might have. Some Windows software depends on other Windows-only systems — like certain audio drivers, registry settings, or system libraries — that DXMT cannot provide. This means a program might have graphics that work perfectly but still fail to run because of something else.

Before you install DXMT, check whether the specific game or software you want to run is known to work on Mac. Websites like ProtonDB (for Steam games) and WineHQ AppDB list which programs work and which do not, and what problems users have reported. This saves you time — if a program is marked as broken, installing DXMT will not fix it.

DXMT also works best on newer Macs with Apple Silicon chips (M1, M2, M3, and later). Older Intel-based Macs can use DXMT, but performance is often slower.

Frequently Asked Questions

Do I need to uninstall DXMT if a game does not work?

No. DXMT sits on your Mac but does not interfere with other programs. If a game does not work, you can leave DXMT installed and try a different game or software. You only need to uninstall it if you want to free up disk space — type brew uninstall dxmt in Terminal to remove it.

Will DXMT slow down my Mac?

DXMT itself does not run all the time — it only works when you launch a program that uses it. When you are not running a Windows game, DXMT is not active. Games translated through DXMT may run slower than they would on Windows, but how much slower depends on your Mac's hardware and the specific game.

Can I use DXMT on an older Mac?

DXMT works on Intel Macs and Apple Silicon Macs, but performance is better on newer hardware. If your Mac is more than five years old, you may find that games run slowly or not at all. Check ProtonDB or WineHQ AppDB for the specific game you want to play — users often report what hardware they tested it on.

Is DXMT safe to install?

DXMT is open-source, meaning the code is public and reviewed by many people. It is maintained by volunteers and has been used safely for years. Installing it through Homebrew is the safest method because Homebrew verifies the source before downloading.

What is the difference between DXMT and Wine?

Wine is a larger compatibility layer that translates many Windows systems, not just graphics. DXMT is specifically a graphics translator. Many tools, including Proton, use both Wine and DXMT together — Wine handles most of the Windows compatibility, and DXMT handles the graphics part.
