- You can use SQL Developer on a Mac to connect to a database running on Windows or Unix/Linux etc., so it still has a place; the fact you can't have a local server running on the same hardware isn't really relevant for most people.
- If you prefer SQL Developer GUI, you can first start the oracle system in Step 10. Then type the command line in the terminal and launch SQL Developer: unset GNOMEDESKTOPSESSIONID sqldeveloper 14. To stop the oracle system, type the command line: sudo service oracle-xe stop.

A Mac version would be fantastic, as the few Mac Oracle IDEs out there are pretty basic. Even Oracle's JDeveloper is barely usable for PL/SQL. Maybe once 10g is released for the Mac later this year more developers will be looking for a decent cross-platform product.

Setup method:
The Tools menu –>brower Filters opens the Order window for Brower folders and sets 'My Objects' to default.
Tools menu –>brower Folders The few directories you regularly order (e.g. Tables views Seq Functions Procedures) Move up a bit and color-coded so that your average look-up time will be much shorter and try.
