Why does `whoami` give a different answer than Current User in Users & Groups?
It is the same account. The name displayed in Users &amp; Groups is your full name, the one shown by whomami is the name of the account as known to the underlying Unix system (and also used as the folder name for your home folder). To check yourself, open Users &amp; Groups, unlock if necessary and then right-click on your user name in the left column. This will show you the technical details behind your account.
