1. Assicurati di aver installato Tails usando o:

  2. Spegni il computer.

    Spegni il computer lasciando inserita la chiavetta USB.

    Inserisci l'altra chiavetta USB Tails dalla quale vuoi eseguire l'installazione.

  3. Plug in your Tails USB stick.

  4. Riaccendi il computer.

    Immediately press-and-hold the Option key (Alt key) when the startup chime is played.

    Hold the key pressed until a list of possible startup disks appears.

    Tasto 'option' o 'alt' in basso a sinistra nella tastiera Mac

  5. Seleziona la chiavetta USB e premi Invio. La chiavetta USB appare come un disco rigido esterno e può avere l'etichetta EFI Boot o Windows come nella seguente immagine da schermo:

    Schermo con il logo di un disco rigido interno etichettato 'Macintosh HD' e un disco rigido esterno etichettato 'Windows' (selezionato)

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

    1. Wait a few minutes. Some USB sticks need some rest after installing.

    2. Make sure that you have installed Tails using either:

    3. Make sure that you have verified your download of Tails.

    4. Make sure that you have verified your download.

    5. Try installing again on the same USB stick.

    6. Try installing on a different USB stick.

    7. 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.

  6. Se il tuo Mac visualizza l'errore seguente:

    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.

  7. Se il computer si avvia con Tails, appare il Boot Loader e Tails si avvia automaticamente dopo 4 secondi.

    Schermo nero ('GNU GRUB') con il logo Tails e 2 opzioni: 'Tails' e 'Tails (Troubleshooting Mode)'.

    • The Troubleshooting Mode entry disables some features of the Linux kernel and might work better on some computers. You can try this option if you think you are experiencing hardware compatibility errors while starting Tails.

    • The External Hard Disk entry makes it possible to start from an external hard disk and some problematic USB sticks.
