Take a look at Alex Ionescu's "Ninja's and Harry Potter" talk from NoSuchCon this year [1].
He specifically mentions he could access the FileVault key of a machine by having physical access, and discovered two secret keys (KPPW and KPST) one of which is enabled when the input buffer is "SpecialisRevelio" [2].

It's a very interesting deck to read through.
