Instale o Tails usando Etcher

Instale um Tails intermediário usando Etcher

Nesse paço você irá instalar um Tails intermediário usando a imagem Tails USB que você baixou anteriormente.

Instalação do Etcher

  1. Clique no link a seguir para baixar o Etcher:

    Baixar Etcher para macOS

  2. Abra o Etcher baixado (no formato DMG disk image).

  3. To install Etcher, drag the Etcher icon onto the Applications icon.

  4. Feche a janela de instalação do Etcher.

    Opcionalmente, ejete a imagem de disco do Etcher da área de trabalho.

Em vez de instalar o Etcher, você pode também instalar o Tails usandoddna linha de comando.

  1. Certifique-se de que o seu dispositivo USB esteja desconectado.

  2. Terminal Aberto de Aplicações ▸ Utilidades ▸ Terminal.app.

  3. Execute o seguinte comando:

    diskutil list

    Ele retorna uma lista dos dispositivos de armazenamento no sistema. Por exemplo:

    /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

  4. Plug your USB stick in the computer.

  5. Execute novamente o mesmo comando:

    diskutil list

    O seu pendrive USB aparece como um novo dispositivo na lista. Confirme se o tamanho que aparece corresponde ao tamanho do seu pendrive USB.

    /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

  6. Anote o nome do dispositivo do seu prendrive USB. NEste exemplo, o pendrive tem 8.0 GB e o seu nome de dispositivo é /dev/disk1. Pode ser que o seu seja diferente.

    Se você não tiver certeza sobre o nome do seu dispositivo, você deverá parar o procedimento ou estará correndo o risco de sobrescrever algum disco rígido do sistema.

  7. 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.

  3. 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:

    Screen with the logo of an internal hard disk labeled 'Macintosh HD' and an external hard disk labelled 'Windows' (selected)

    If the USB stick does not appear in the list of startup disks:

    1. Make sure that you have verified your download of Tails.
    2. Try installing again on the same USB stick.
    3. Try installing on a different USB stick.
    4. 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.

  4. 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:

    1. Turn on your Mac, then press and hold Command(⌘)+R immediately after you see the Apple logo. Your Mac starts up from macOS Recovery.

    2. When you see the macOS Utilities window, choose Utilities ▸ Startup Security Utility from the menu bar.

    3. When you are asked to authenticate, click Enter macOS Password, then choose an administrator account and enter its password.

    Startup Security Utility

    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.
