“While Apple hasn’t said — it never does — when it will release Mavericks 10.9.5, it’s almost certain to be the last update that includes non-security bug fixes, the kind of performance and reliability improvements that Mac owners hunger for, or changes to existing features in the OS,” Keizer reports. “Both Lion (OS X 10.7) and Mountain Lion (10.8) reached x.x.5 and no further, for instance… [It’s] likely that Apple will deliver Mavericks 10.9.5 some time in September.”
“More important than the delivery date for the last non-security Mavericks refresh is the fact that the same day will also mark the end of security patches for 2011’s Lion, or OS X 10.7,” Keizer reports. “Halting patches for OS X Lion customers would, of course, be painful — and potentially risky — for them, but Apple probably won’t blink an eye. As of July, Lion accounted for just 10% of all versions of OS X in use, according to metrics company Net Applications. By the end of September, Lion’s user share will be about 8%, assuming it continues to drop at the rate it has over the last six months. That will be less than half of Snow Leopard’s share when Apple pulled its plug last year.”
