How to manage Trezor devices using trezorctl on macOS or Tails

Requirements

• Computer running macOS Big Sur or Monterey or Tails USB flash drive or SD card
• Trezor device

Caveats

• When copy/pasting commands that start with $, strip out $ as this character is not part of the command

Setup guide (macOS-only)

Heads-up: trezorctl is pre-installed on Tails so setup guide can be skipped.

Step 1: install Homebrew

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

$ uname -m | grep arm64 && echo 'export PATH=$PATH:/opt/homebrew/bin' >> ~/.zshrc && source ~/.zshrc

Step 2: disable Homebrew analytics

brew analytics off

Step 3: install libusb

brew install libusb

Step 4: install attrs and trezorctl

pip3 install --user attrs trezor

Step 5: source Python 3 bin directory

Heads-up: replace 3.8 with semver of latest version of Python 3 found using ls $HOME/Library/Python.

echo 'export PATH=$PATH:$HOME/Library/Python/3.8/bin' >> ~/.zshrc
source ~/.zshrc

Usage guide

Heads-up: on Tails, one needs to add torsocks before trezorctl commands (example: torsocks trezorctl firmware-update).

Install or update firmware

Heads-up: connect device in bootloader mode before running command.

Heads-up: Trezor devices ship without firmware so one needs to install firmware before setting up device.
