That almost ALWAYS means that you haven't provided the proper configuration values or may have a firewall installed.

Not sure for mac but the default port is normally 1521 for Oracle so double check that.

And are you entering a hostname? If so, you didn't show it.

If you have an Oracle client make sure you can connect using that.

1433 sounds suspiciously like a MSSQL port number.

Do you have a database installed anywhere? You don't mention it.
