Upgrading your Mac is recommended because it brings security, performance, and usability improvements. These benefits are outlined below.
The normal path to upgrade is via the System Settings/General/Software Update options. If you get prompted to provide an administrator user name and password and are not able to update this way then please launch the Self Service App and look out for the upgrade policy options within Core Software.
