Apple Security Advisory: OS X Mavericks 10.9.3.3 is a security update. The update includes bug fixes, oops, new features and improvements. The OS X 10.3 update is just under 0.5GB if you are already on 10.2, or just under 1GB for the Combo update. Some Naked Security readers have told us that theyre sticking with older versions of OS X, and avoiding Mavericks altogether, because Mavericks forces you to sync iOS devices via Apples cloud service, rather than regular USB cable.”]
