22 2. Place your keyboard into reset.
23 3. Press the `Find Device` button and ensure that your keyboard is found.
24 4. Press the `Open .hex File` button and locate the `.hex` file you created.
25 5. Press the `Flash Device` button and wait for the process to complete.
28 1. Install homebrew by typing the following:
30 /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
32 2. Install `crosspack-avr`.
34 brew cask install crosspack-avr
