Installing Trezor Bridge on Mac and Windows: Step-by-Step Guide

If you're planning to use your Trezor hardware wallet through a web browser, such as Chrome or Firefox, you'll need to install a small but essential utility called Trezor Bridge. It enables secure communication between your computer and the Trezor device—especially when using the Trezor Suite Web or third-party wallet apps like MetaMask.

In this guide, you’ll learn exactly how to download, install, and troubleshoot Trezor Bridge on both macOS and Windows systems.

What Is Trezor Bridge?

Trezor Bridge is a background service that acts as a communication link between your Trezor hardware wallet and browser-based interfaces. Without it, your browser won’t recognize or interact with the device securely.

You don’t need Trezor Bridge if you’re using Trezor Suite Desktop, but it’s required for:

  • Trezor Suite Web
  • MetaMask (when connecting a hardware wallet)
  • MyEtherWallet, MyCrypto, and other third-party tools

✅ Before You Begin

Make sure you have:

  • A Trezor Model One or Trezor Model T
  • A USB cable to connect your Trezor
  • A modern browser (Chrome, Firefox, Brave, Edge)
  • Admin rights on your computer to install new software

🖥️ Installing Trezor Bridge on Windows

Step 1: Download the Installer

Go to the official download page:
👉 https://trezor.io/bridge

Click “Download for Windows” to start the installer download.

Step 2: Run the Installer

  • Locate the downloaded .exe file in your Downloads folder
  • Double-click to launch the installer
  • Follow the on-screen prompts to complete installation
🔐 You might see a Windows security prompt. Choose “Yes” to allow installation—it’s from SatoshiLabs, the official developer.

Step 3: Restart Your Browser

Once installed, close and reopen your browser. This allows the new service to be recognized by browser-based apps.

🍏 Installing Trezor Bridge on macOS

Step 1: Download the Installer

Visit the same page:
👉 https://trezor.io/bridge

Click “Download for macOS” to get the .dmg file.

Step 2: Install the App

  • Open the .dmg file
  • Drag the Trezor Bridge icon into your Applications folder
  • Launch the app if prompted, or let it run in the background
🔐 macOS may ask for security approval:
Go to System Preferences > Security & Privacy, then click “Allow” for Trezor Bridge under the General tab.

Step 3: Restart Your Browser

Quit and reopen your browser to complete the connection process.

🧪 How to Test If Trezor Bridge Works

After installation:

  1. Plug in your Trezor device via USB
  2. Open your browser and visit:
    👉 https://suite.trezor.io/web
  3. Click “Connect Trezor”
  4. If the device is recognized and you can continue to your dashboard, Trezor Bridge is working correctly.

🛠️ Troubleshooting Tips

❌ Problem: Trezor not detected

Fix:

  • Make sure Bridge is installed and browser restarted
  • Try a different USB port or cable
  • Check browser permissions and disable conflicting extensions

🔁 Updating Trezor Bridge

Trezor Bridge now includes automatic updates, so in most cases, you don’t need to do anything. If you experience issues or Bridge isn’t working, simply:

  1. Uninstall the existing version
  2. Download the latest installer from trezor.io/bridge
  3. Reinstall and restart your browser
