Trezor Bridge — Installation Deep Dive

Step-by-step install checklist and pre/post-install actions for Windows, macOS, and Linux (educational only).

Before you install — quick prechecks

Close browser tabs that interact with hardware wallets to avoid conflicts.
Back up your recovery seed and verify it before doing firmware updates.
Only download installers from the vendor's official channel — do not follow random ads.
On Linux, be ready to adjust USB permissions / udev rules for device access.

Windows — installation (summary)

Obtain the installer package and verify authenticity if checksums/signatures are provided.
Close wallet/browser tabs, then run the installer as administrator if prompted.
Accept any driver prompts required by Windows and complete the install.
Restart your browser and connect the Trezor device; the web UI should detect it via Bridge.

Tip: If drivers fail, try a different USB cable/port and re-run installer as admin.

macOS — installation (summary)

Open the downloaded .dmg/.pkg and run the installer following prompts.
Grant any Security & Privacy approvals if macOS blocks the installation.
Restart your browser and connect your device; approve actions on the device screen.

Linux — installation (general tips)

Use distribution-specific packages or follow official instructions for your distro.
Set udev rules so your user can access the Trezor device (requires sudo to install rules).
Log out / in or reboot after changing udev rules for them to take effect.

Post-install checks

Confirm Bridge is running (system tray / process list) before opening wallet pages.
Reload your web wallet or restart the app and test detection with your device connected/unlocked.
If detection fails: try another USB cable/port, temporarily disable conflicting extensions, and ensure Bridge is up-to-date.
