Mac OS X users with empty name Looking at my Users &amp; Groups I have just noticed two users I never payed any attention before. 
Maybe they already exist from the beginning of time i.e. when my macbook pro was installed for the first time.
But, as told, I have never, ever, ever noticed them.

Does anyone know where these users come from and if I can delete them?
No clue where they come from, is your macbook refurbished by any chance?

Just remove them if you don't use them.

They have no username, so they kinda don't have any folder related.
