Security Update 2015-005 for OS X Mavericks & Mountain Lion Available
Mac users on OS X Mavericks 10.9.5 and OS X Mountain Lion 10.8.5 will find two important software updates available to them, labeled as Security Update 2015-005 and Mac EFI Security Update 2015-001. The updates include patches and fixes to significant potential security issues and are therefore recommended for all Mac users running Mavericks and Mountain Lion to install. For Macs running Yosemite, the OS X Yosemite 10.10.4 update includes the same set of security fixes, and a separate update is not required.
