[Tails-testers] [Tails-news] Call for testing: 4.5~rc1

Tails 4.5, scheduled for April 7, will be the first version of Tails to
support Secure Boot.

You can help Tails by testing the release candidate for Tails 4.5 now.

# Secure Boot

Tails 4.5~rc1 should start on computers in UEFI mode and with Secure Boot
enabled.

# Known issues

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 change the settings of the _Startup Security
Utility_ of your Mac to authorize starting from Tails.

[Read our instructions on how to authorize starting from Tails on your
Mac.](https://tails.boum.org/news/index.en.html#news-test-4.5-rc1.mac)

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](https://support.apple.com/kb/HT201314).

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.

security-utility.png)

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](https://support.apple.com/en-us/HT204455), 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 it will require an in-person service appointment with an Apple Store or Apple Authorized Service Provider.**
