Can someone point me to a link or provide some clarity on what NOT having a firmware password means in terms of security and, as a home user, do i need to put on on? All my personal files are in 'Knox' dmgs - i work out of the dmgs - works perfectly. But i dont know for sure where else other background/usage info is stored on the computer. I did a search on google & these forums and nothing clear came up.... I remember i while back reading that without firmware password if someone got your mbp (physical possession) then they could reset the password and get into your user account (with mac osx cd) ... can someone confirm (im reasonably sure this is correct). I had the password on my last mbp but havent got around to putting it on this new one. I was about to today but its been awhile and maybe there is new information or perspective for me to consider. How many of you have a password installed? What are the pro's & con's? Many Thanks.
