I followed these steps for testing on a MacBook Pro 13-inch, 2019 (MacBookPro15,2).
With Secure Boot turned on (Full Security):
• Tails boot menu did not appear on start-up. Apple logo appeared, and after a while, system opened in Recovery Mode, with dialog: “Unable to verify startup disk. Try again or select another startup disk.”
With Secure Boot turned on (Medium Security):
• Tails boot menu did not appear on start-up. Apple logo appeared, and after a while, system opened in Recovery Mode, with dialog: “The version of macOS on the selected disk needs to be reinstalled. Use macOS Utilities to reinstall macOS or select another startup disk.”
With Secure Boot turned off (No Security):
• First time attempting to boot in this mode, Tails launcher did appear, and start booting - however, notebook reset before GUI loading screen could appear. All subsequent boots showed same dialog as ‘Medium Security’ above.

Hi,
our first USB images that support Secure Boot are out!
Under the hood, they include two major technical changes:
- switch the boot loader from syslinux to GRUB for EFI boot
- switch from aufs to overlayfs
Please consider testing them :)
Here's how:
1. Download the USB image (.img) from
https://nightly.tails.boum.org/build_Tails_ISO_feature-6560-secure-boot/lastSuccessful/archive/build-artifacts/
2. Install the downloaded USB image to a spare USB stick,
using Etcher (Windows, macOS) or GNOME Disks (Linux).
3. Start from this USB stick on various computers
In particular, we're interested in test results on:
4. Do as much exploratory testing as you would like
5. Report back success or failure to this public mailing list:
