I've got a MacBook Pro protected with FileVault 2 (10.9), and can't remember the password to unlock the disk.
When I boot, it asks for the "Disk Password".
What I have is the recovery key that I printed on paper when I activated FileVault.
How do I use it ?
Entering a wrong password multiple times doesn't prompt for the recovery key, and sometimes a '?' appears but it doesn't do anything.
(I've read http://support.apple.com/kb/ht4790, but it doesn't explain how to use the recovery key.)
