TAILS OSX
Following this guide you will be able to create a TAILS image that will work on OSX without requiring any REFIT or bootloader modifications to the target system.
Dependencies
In order to create a TAILS disk image for OSX you will need the following dependencies:
The easiest way to install these is with homebrew:
brew install git gpg
If you want to build the EFI bootloader yourself you will also need:
Setup TAILS OSX
git clone https://github.com/hellais/TAILS-OSX.git
cd TAILS-OSX
Create the EFI bootloader (optional)
You can build the EFI bootloader directly from Mac OSX (given you have installed vagrant and virtualbox) by running:
vagrant up
This is basically running this command from inside a linux box:
grub2-mkimage -d /usr/lib/grub2-efi/x86_64-efi/ -o BOOTX64.efi \
-O x86_64-efi --prefix /efi/boot part_gpt part_msdos lvm fat ext2 \
chain boot configfile normal minicmd linux reboot halt search \
gfxterm gfxmenu efi_gop efi_uga video loadbios gzio video_bochs \
video_cirrus echo true loadenv
Build the image
./create-image.sh
You will be asked to select a volume that will be formatted and will contain the TAILS live cd.
The script will then proceed to fetch TAILS, verify the signature, mount the iso, move some files in the ISO over to the USB disk and then configure grub properly.
Once you have finished this you will have a usb disk you can boot by holding down the alt-option key at startup.
