On a Mac you should ensure that the operating system and applications are kept up-to-date as regards security and bug-fixing updates issued by Apple
Users of older versions of OS X should use Software Update (from System Preferences) to configure 'Automatically check for updates when you have a network connection'. This can be set to Daily, Weekly or Monthly. More information is available from Apple.
Mountain Lion or later users should use App Store (from System Preferences) and enable 'Automatically check for updates' and 'Install app updates'.
MacOS X 10.11 and earlier are now out of-support and no further updates will be available. Please consider upgrading to a more modern version of the operating system.
