I had a computer crash. I have a copy of my vault on my iPhone. I had do reformat my disk and restore it from a clone, but the vault vanished. I want to move my vault from my iPhone to my mac. What should I do? It does not show up in the finder anywhere.
Do you mean that you use iCloud to sync between your mac and iPhone? If so, now both of them should have nothing left, cause iCloud will mark them as deleted which I just experience yesterday.
To recovery your data, do as follow:
login to iCloud website
click “Account Settings”
move to the bottom and click “Advanced → Restore Files”
