I know this has been answered before, but on google and MR forums I can't seem to find a similar post. A co-worker upgraded to a new Mac Pro, and in the process of migrating decided to create a new main user account instead of keeping the old one. He migrated the old user account along side the new one, and then manually transferred the user folder's content. Now when he installs software or updates, the permissions dialog won't accept his new user name/password (even though it's set as an administrator in Sys Prefs). Instead he has to keep typing in the old user name/password. Could someone help us resolve this?
