Obtain FileVault 2 recovery key with administrator account I enabled full disk encryption on my new MacBook Pro.  (I am new to the Mac world but an accomplished Linux/UNIX and Windows type)

However, I made a mistake and skipped the step of taking note of the recovery key.  

Is is possible to get the recovery key at this point?
It seems strange OS X didn't present you the recovery key. Try:

sudo fdesetup changerecovery -personal


This awesome blog has probably all the info you desire. Look for the section "Managing individual and institutional recovery keys". You can use your Filevault2 password to change the recovery key. And you will have to use an Administrator account.
