Plug your USB stick into the computer.

Execute again the same command.

In this example, the USB stick is 8.0 GB and its device name is <span class="command-placeholder">/dev/disk1</span>.
Yours might be different.

Execute the following command to safely eject the USB stick. Replace <span class="command-placeholder">device</span> with the device name found in step 6.

Execute the following commands to copy the USB image that you downloaded earlier to the USB stick. Replace:

<p class="command-template">dd if=/Users/me/tails-amd64-3.12.img of=/dev/rdisk9 bs=16m && sync</p>

<div class="note">
<p>If you get a <code>Permission denied</code> error, try
adding <code>sudo</code> at the beginning of the command:</p>

<p class="command-template">sudo dd if=<span class="command-placeholder">tails.img</span> of=<span class="command-placeholder">device</span> bs=16m && sync</p>

<p>If you get an <code>invalid number ‘16m’</code> error, try
using <code>16M</code> instead:</p>

<p class="command-template">dd if=<span class="command-placeholder">tails.img</span> of=<span class="command-placeholder">device</span> bs=16M && sync</p>

The installation is complete when the command prompt reappears.

Open the *balenaEtcher* download (DMG disk image).

Optionally, eject the disk image of *balenaEtcher* from the sidebar of *Finder*.

<p>All the data on this USB stick will be lost.</p>

<div class="note">
<p>Make sure that the USB image is called <i>[[!inline pages="inc/stable_amd64_img_filename" raw="yes" sort="age"]]</i> and has an
<i>.img</i> file extension.</p>

Click **Flash**.

Close *balenaEtcher*.
