Preferences can be configured via System ▸ Preferences ▸ System ▸ Software Updates. You can configure it to check for updates on a daily, hourly or weekly basis or never. Note that these frequencies are only approximate, and checks for updates can be triggered by other events, such as the screen being unlocked, network becoming available, or another user checking for updates. The default setting is to check for updates daily. You can also configure it to automatically install all updates or just the ones that fix security issues. These settings are per-user and effective only for the current user logged in the system.
