If Apple sticks to its practice of the last two years, Monday's OS X updates will either be the next-to-last or second-to-last issued before OS X 10.10, aka "Yosemite," ships this fall. After Yosemite launches — or possibly just before — Apple will probably stop serving OS X Lion with security updates, just as it halted those for Snow Leopard last September, several weeks before Mavericks' debut.
According to metrics vendor Net Applications, Lion powered just 12% of all Macs which went online in May.
Mavericks 10.9.4 and Security Update 2014-003 can be retrieved by selecting "Software Update..." from the Apple menu, or by opening the Mac App Store application and clicking the Update icon at the top right.
iOS 7.1.2 can be downloaded over the air or through iTunes. To initiate an over-the-air update on an iPhone, for instance, users must tap the "Settings" icon, then the "General" button on the resulting screen. Tapping "Software Update" will kick off the update process.
