[zappoi]

Hello, with fvdeinfo 20170917 it's impossible to mount / have infos on Filevaulted devices: it's says Unable to unlock keys.

What diskutil shows:

Do you have an idea of what I'm doing wrong ? Thanks!

I compile an older version (fvdeinfo 20170527) and the debug output worked output file log

libfvde does not seem to find the correct offset of the encrypted volume. I'll have a look when time permits
