To configure a DSN on Mac OS X you should use the ODBC Administrator. If you have Mac OS X 10.2 or earlier, refer to Section 25.1.3.4, “Configuring a Connector/ODBC DSN on Unix”. Select whether you want to create a User DSN or a System DSN. If you want to add a System DSN, you may need to authenticate with the system. You must click the padlock and enter a user and password with administrator privileges.
Open the ODBC Administrator from the
Utilities folder in the
Applications folder.

On the User DSN or System DSN panel, click Add.
Select the Connector/ODBC driver and click OK.
You will be presented with the Data Source
Name dialog. Enter The Data Source
Name and an optional
Description for the DSN.

Click Add to add a new keyword/value
pair to the panel. You should configure at least four pairs
to specify the server,
username, password and
database connection parameters. See
Section 25.1.3.5, “Connector/ODBC Connection Parameters”.
Click OK to add the DSN to the list of configured data source names.
A completed DSN configuration may look like this:

You can configure additional ODBC options to your DSN by adding further keyword/value pairs and setting the corresponding values. See Section 25.1.3.5, “Connector/ODBC Connection Parameters”.
