Hello, I have FileVault 2 Enabled on my Yosemite install (2014 Air) and I have a few questions. If I am understanding correctly if I do a full shutdown (Logout > Shutdown) the next time I boot the computer I should be presented with a grey wallpaper in pre-boot before the disc is unlocked. My concern is that no matter how the computer is shut down I am always presented with the normal login screen with my wallpaper etc. Does this mean that FV2 is not working? How do I force it to move to the "dual" login where the grey screen appears again? I have used "sudo fdesetup status" and it does show the status as ON. Thank you.
