By default, in Mac OS X Leopard, any user can adjust the wireless network settings and connect to any available network. This may be convenient for most situations, but many users might wish to restrict non-administrator users from changing these settings.
Users should follow these steps:
- Log in as an administrator and go to the “Network” system preferences.
- Select the AirPort interface and click the “Advanced” button.
- In the AirPort tab, use the plus (+) or minus (-) buttons to add or remove wireless networks, only adding desired networks to the list.
- Uncheck “Remember any network this computer has joined”
- Check both “Disconnect from wireless networks when logging out”
- Check “Require Administrator password to control AirPort”.
- Click “OK” to save changes.
- With the advanced options closed and the AirPort interface still selected, uncheck “Ask to join new networks”.
- Click “Apply” to save changes.
