Public beta
Official x86_64 live ISO for testing. When you want persistence, install from the live session — do not treat the boot stick as your home directory.

Latest release

X86_64

First public beta: 2026.08.14. The raw ISO is ~2.9 GiB, so GitHub ships split parts — reassemble, then verify sha256 (instructions on the release). Channel pin: cicada-stable · Helium hash-locked in-tree.

# after downloading all .part-* files + .sha256 from the release
cat cicada-2026.08.14-x86_64.iso.part-* > cicada-2026.08.14-x86_64.iso
shasum -a 256 -c cicada-2026.08.14-x86_64.iso.sha256

Verify before you boot

FAIL CLOSED
  1. Download the ISO + checksum from the same release Prefer the release assets page — not a random Drive link.
  2. Check the sha256
    shasum -a 256 cicada-*.iso
    # compare to the published checksum on the release
  3. Flash (macOS example)
    diskutil list
    # confirm ~250GB stick diskN — wrong disk wipes that drive
    diskutil unmountDisk /dev/diskN
    sudo dd if=./cicada-YYYY.MM.DD-x86_64.iso of=/dev/rdiskN bs=4m status=progress
    sync
    diskutil eject /dev/diskN

After flash

ALERT

macOS may say the disk is unreadable. Eject — never Initialize. Default boot = non-hardened live. Live user cicada / empty password. Install when you want persistence — see Install.
