Detailed system requirements and recommended hardware.

Summary

Tails works on:
- Most PC computers that are less than 10 years old
- Some older Mac computers with an Intel processor
Tails does not work:
- Newer Mac computers with an Apple processor (M1 or M2)
- Smartphones or tablets
- Raspberry Pi
Tails might not work on:
- Some older computers, for example, if they don't have 2 GB of RAM.
- Some newer computers, for example, if their graphics card is incompatible with Linux. Nvidia or AMD Radeon cards often do not work in Tails.

See our list of known hardware compatibility issues.

Detailed hardware requirements

A USB stick of 8 GB minimum or a recordable DVD.

All the data on this USB stick or DVD is lost when installing Tails.
The ability to start from a USB stick or a DVD reader.
A 64-bit x86-64 IBM PC compatible processor.
- Tails does not works on ARM or PowerPC processors.
- Tails does not work on 32-bit computers since Tails 3.0 (June 2017).
2 GB of RAM to work smoothly.

Tails can work with less than 2 GB RAM but might behave strangely or crash.

Recommended hardware

Laptop models evolve too rapidly for us to be able to provide an up-to-date list of recommended hardware. Below are some guidelines if you, or your organization, are considering acquiring a laptop dedicated to running Tails.

For PC

Avoid "gaming" models with Nvidia or AMD Radeon graphics cards.
Consider buying a refurbished laptop from a high-end (professional) series. These are cheaper and will last longer than new but lower-quality laptops.
- For example, the Lenovo ThinkPad series work well with Tails, including the X250, X1 Carbon, T440, T480, and T490 models.
- If you live in a part of the world where buying refurbished laptops is uncommon, look on eBay and Amazon. Amazon offers a 90-day Amazon Renewed Guarantee.
Consider buying a new laptop from vendors who guarantee the compatibility with Linux and Tails like ThinkPenguin.

For Mac

Unfortunately, we don't know of any Mac model that works well in Tails and can run the latest macOS version.

Make the computer start on the USB stick

Make sure that you have installed Tails using either:
Click on the Start 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 or the Use a device option don't 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.

If your Windows has no Boot Menu option available, make sure that your intermediary Tails USB stick is plugged in and choose your USB stick directly in the list of devices.

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.
- 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.

Most computers do not start automatically on the Tails USB stick, 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:

Make sure that you have installed Tails using either:
Shut down the computer while leaving the USB stick plugged in.

Shut down the computer and plug in the Tails USB stick.

Shut down the computer.

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:

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:
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.
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.

Troubleshoot Tails not starting

If no Boot Menu appears, refer to the instructions on starting Tails using the Boot Menu key.
If none of the possible Boot Menu keys from the previous technique work, refer to the troubleshooting instructions about Tails not starting at all.
If the Boot Menu appears but your USB stick is not listed in the Boot Menu:
1. Wait 2–3 minutes and try again. Some USB sticks need some rest after installing.
2. Try all other USB ports on the computer. Some USB ports cannot be used to start from.
If your USB stick is listed in the Boot Menu but the Boot Loader does not appear:

If your USB stick appears in the list of startup disks but the Boot Loader does not appear:
1. 等候 2-3 分钟，然后再试。有些 U 盘在安装 Tails 之后需要稍缓一下。
2. 试试电脑上的其它 USB 接口，因为有些 USB 接口不能用于启动 Tails。
3. 请确认你已经使用下述方法安装 Tails：
4. 请确认你已经验证你下载到的 Tails 文件.

Starting the computer using a Boot Menu key can be faster than starting the computer on Windows first and then on Tails. We recommend you learn how to start Tails using the Boot Menu key if you use Tails regularly.

Apple does not prioritize collaborating with Free Software projects. Their newest hardware is usually very hard for Free Software developers to get working with Linux, and thus Tails. PC hardware tends to be more open and work better with Linux.

Welcome to Tails!
