===== GNU/Linux or macOS: =====

<ol style="list-style-type: decimal;">
<li><p>Open the terminal and type one of the following commands depending on the system used:</p>
<pre>sudo fdisk -l # GNU/Linux</pre>
<pre>diskutil list # macOS</pre></li>
<li><p>Make note of drives in the system. Do not erase these.</p></li>
<li><p>Plug in the flash drive.</p></li>
<li><p>Open the terminal and type one of the following command again:</p>
<pre>sudo fdisk -l # GNU/Linux</pre>
<pre>diskutil list # macOS</pre></li>
<li><p>Make note of the drive that was not present before. Write it down.</p></li>
<li><p>Double-check size/brand/model to make sure this new device is the device you plugged in.</p></li>
<li><p>Now, unplug the drive you just plugged in.</p></li>
<li><p>Run:</p>
<pre>sudo fdisk -l # GNU/Linux</pre>
<pre>diskutil list # macOS</pre></li>
<li><p>Does the drive you wrote down in step 5 still appear? If so, you made a mistake, and you’re on your way to deleting all of your data. Don’t do that. Do not pass go, do not collect $200 – back to the beginning. If not, you can now plug your drive back in.</p></li>
<li><p>Run:</p>
<pre>sudo fdisk -l # GNU/Linux</pre>
<pre>diskutil list # macOS</pre></li>
<li><p>If the drive that did not appear last time, appears this time, and is the same device as in step 5, you are likely on your way to not erasing your entire system. Good job, that makes you less of an idiot than me; a low bar, but it’s something.</p></li>
<li><p>Run the following, replacing <code>/dev/sdX</code> with your drive, and replace the pfSense img file with the filename of your image file:</p>
<pre>sudo dd if=pfSense-CE-memstick-serial-*.img of=/dev/sdX bs=1M status=progress</pre></li></ol>

Your bootable USB drive with pfSense is now ready for use! If you managed to erase your entire computer by writing pfSense’s image to your operating system drive EVEN AFTER all of this, congratulations, you’re almost as stupid as me.
