Alright i've had my macs for awhile and this has happened a couple of times specifically with my macbook pro where I perform a proper shut down and upon the next time i power up i get the originally settings set again. Such as my dock contains all the original factory apps (any i added are gone) applications such as safari dont contain any of my bookmarks. When i opened up MS office i get prompted with a dialog telling me this is the first time i have opened this app. Does anybody know why this happens.... its getting annoying
