As Microsoft turned its attention away from working directly on ODBC, the Unix field was increasingly embracing it. This was propelled by two changes within the market, the introduction of graphical user interfaces (GUIs) like GNOME that provided a need to access these sources in non-text form, and the emergence of open software database systems like PostgreSQL and MySQL, initially under Unix. The later adoption of ODBC by Apple for using the standard Unix-side iODBC package Mac OS X 10.2 (Jaguar) (which OpenLink Software had been independently providing for Mac OS X 10.0 and even Mac OS 9 since 2001) further cemented ODBC as the standard for cross-platform data access.
