Trying to delete a user account through the user/groups panel in System Preferences in the normal way.
However. the "-" associated with the particular user is greyed out. (I think its because the Mac was previously on a domain)
When I check the Unique ID of the account it returns the value of 0 (the root account also has the value of 0)
How can I get rid of the account or at least change the Unique ID?
