Install Tails using Etcher
Install an intermediary Tails using Etcher
In this step, you will install an intermediary Tails using the Tails USB image that you downloaded earlier.
Install Etcher
Click on the following link to download Etcher:
Open the Etcher download (DMG disk image).
To install Etcher, drag the Etcher icon onto the Applications icon.
Close the installation window of Etcher.
Optionally, eject the Etcher disk image from the desktop.
Instead of installing Etcher, you can
also install Tails using dd
on the command
line.
Make sure that your USB stick is unplugged.
Open Terminal from .
Execute the following command:
diskutil list
It returns a list of the storage devices on the system. For example:
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS MacDrive 250.0 GB disk0s2 3: EFI 134.1 GB disk0s3 4: Microsoft Basic Data BOOTCAMP 115.5 GB disk0s4
Plug your USB stick in the computer.
Execute again the same command:
diskutil list
Your USB stick appears as a new device in the list. Check that its size corresponds to the size of your USB stick.
/dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme ∗500.1 GB disk0 1: EFI 209.7 MB disk0s1 2: Apple_HFS MacDrive 250.0 GB disk0s2 3: EFI 134.1 GB disk0s3 4: Microsoft Basic Data BOOTCAMP 115.5 GB disk0s4 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *8.0 GB disk1 1: Apple_HFS Untitled 1 8.0 GB disk1s1
Take note of the device name of your USB stick. In this example, the USB stick is 8.0 GB and its device name is /dev/disk1. Yours might be different.
If you are unsure about the device name, you should stop proceeding or you risk overwriting any hard disk on the system.
Execute the following commands to copy the USB image that you downloaded earlier to the USB stick.
Replace:
tails.img with the path to the USB image
If you are unsure about the path to the USB image, you can insert the correct path by dragging and dropping the icon of the USB image from Finder onto Terminal.
device with the device name found in step 6
You can try adding r before disk to make the installation faster.
diskutil unmountDisk device
dd if=tails.img of=device bs=16m && sync
You should get something like this:
dd if=/Users/me/tails-amd64-3.12.img of=/dev/rdisk9 bs=16m && sync
If no error message is returned, Tails is being copied on the USB stick. The copy takes some time, generally a few minutes.
If you get a Permission denied error, try adding
sudo
at the beginning of the command:sudo dd if=tails.img of=device bs=16m && sync
If you get an invalid number ‘16m’ error, try using
16M
instead:dd if=tails.img of=device bs=16M && sync
The installation is complete once the command prompt reappeared.

Make the computer start on the USB stick
Click on the
button.Press and hold the Shift key while you choose Power ▸ Restart.
In the Choose an option screen, choose Use a device.
If the Choose an option screen does not appear, refer to the instructions on starting Tails using the Boot Menu key.
In the Use a device screen, choose Boot Menu.
Windows shuts down, the computer restarts, and a Boot Menu appears.
Plug in your Tails USB stick shortly after choosing Boot Menu and while Windows is shutting down.
In the future, we We recommend that you only plug in your Tails USB stick while Windows is shutting down. Otherwise, a virus in Windows could infect your Tails USB stick and break its security.
Such an attack is possible in theory but very unlikely in practice. We don't know of any virus capable of infecting Tails. See our warning on plugging Tails in untrusted systems.
The Boot Menu is a list of possible devices to start from. The following screenshot is an example of a Boot Menu:
In the Boot Menu, select your USB stick and press Enter.
If the computer starts on Tails, the Boot Loader appears and Tails starts automatically after 4 seconds.
Most computers do not start on the Tails USB stick automatically but you can press a Boot Menu key to display a list of possible devices to start from.
If Windows 8 or 10 is also installed on the computer, you can refer instead to the instructions on starting Tails from Windows 8 or 10. Starting Tails from Windows is easier than using the Boot Menu key.
The following screenshot is an example of a Boot Menu:
This animation summarizes how to use the Boot Menu key to start on the USB stick:
The following instructions explain in detail how to use the Boot Menu key to start on the USB stick:
-
Shut down the computer while leaving the USB stick plugged in.
Shut down the computer and plug in the Tails USB stick.
Fahren Sie den Computer herunter.
Plug in the other Tails USB stick that you want to install upgrade from.
Unplug your Tails USB stick while leaving the intermediary USB stick plugged in.
-
Identify the possible Boot Menu keys for the computer depending on the computer manufacturer in the following list:
Manufacturer Key Acer F12, F9, F2, Esc Apple Option Asus Esc Clevo F7 Dell F12 Fujitsu F12, Esc HP F9 Huawei F12 Intel F10 Lenovo F12 MSI F11 Samsung Esc, F12, F2 Sony F11, Esc, F10 Toshiba F12 others… F12, Esc On many computers, a message is displayed very briefly when switching on that also explains how to get to the Boot Menu or edit the BIOS settings.
-
Switch on the computer and immediately press several times the first possible Boot Menu key identified in step 2.
-
If the computer starts on another operating system or returns an error message, shut down the computer again and repeat step 3 for all the possible Boot Menu keys identified in step 2.
If a Boot Menu with a list of devices appears, select your USB stick and press Enter.
If the computer starts on Tails, the Boot Loader appears and Tails starts automatically after 4 seconds.
-
Shut down the computer while leaving the USB stick plugged in.
Plug in the other Tails USB stick that you want to install from.
-
Switch on the computer and immediately press-and-hold the Option key (Alt key) until a list of possible startup disks appears.
-
Choose the USB stick and press Enter. The USB stick appears as an external hard disk and might be labeled EFI Boot or Windows like in the following screenshot:
If the USB stick does not appear in the list of startup disks:
- Make sure that you have verified your download of Tails.
- Try installing again on the same USB stick.
- Try installing on a different USB stick.
- Try using the same USB stick to start on a different computer.
If your computer still does not display the Boot Loader, it might currently be impossible to start Tails on your computer.
-
If your Mac displays the following error:
Security settings do not allow this Mac to use an external startup disk.
Then you have to change the settings of the Startup Security Utility of your Mac to authorize starting from Tails.
To open Startup Security Utility:
Turn on your Mac, then press and hold Command(⌘)+R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery.
When you see the macOS Utilities window, choose Utilities ▸ Startup Security Utility from the menu bar.
When you are asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.
In the Startup Security Utility:
Choose No Security in the Secure Boot section.
Choose Allow booting from external media in the External Boot.
To still protect your Mac from starting on untrusted external media, you can set a firmware password, available on macOS Mountain Lion or later. A firmware password prevents users who do not have the password from starting up from any media other than the designated startup disk.
If you forget your firmware password you will require an in-person service appointment with an Apple Store or Apple Authorized Service Provider.
