If the account you use for development is not an administrative account you will be asked to enter the name and password for a user who is in the Developer Tools group once per login. To get around this you can add your account’s username to the _developer group.
- To make life simple log in to an administrative account.
- Launch Terminal.
- Type: sudo dscl . append /Groups/_developer GroupMembership <username>.
- Quit Terminal and log out of the administrative account.
