Set a Software Update Schedule
You can ensure that your Mac and the applications that come with OS X are up to date with the latest features and fixes by setting a schedule for updating the software. Apple makes OS X updates available from time to time. These updates fix problems, add new features, and resolve security issues. You can reduce computer problems and maximize online safety by setting up OS X to download and install these updates automatically. By default, OS X checks for updates weekly. You can configure Software Update to check for updates daily or only once a month.
