Why does Storage Studio say it couldn't unlock Delta Drive on this Mac?
Short answer: This Mac can no longer open Delta Drive's access details (for example on a new or restored Mac). Your files are safe — enter your recovery kit to reconnect.
Storage Studio keeps what it needs to open Delta Drive on this Mac. That's no longer readable here — for example after moving to a new Mac or restoring this one from a backup. Your files are safe.
Enter your recovery kit to reconnect this Mac. Once it's accepted, Delta Drive opens as before.
