Apple announced all sorts of stuff yesterday - iPhones, watchOS 2, iOS 9, Apple TV, and of course, a very big iPad. The event was never intended to be about the company"s Mac line, but Mac owners may be interested in a bit of info that Apple quietly revealed yesterday.
Until yesterday, the main page for OS X El Capitan stated that the new operating system update was "coming this fall". However, as Ars Technica spotted, Apple updated the page, so that it now reads: "Coming September 30."
El Capitan - known also as OS X 10.11 - was announced back in June, when Apple said the new release would focus on improving performance and the overall user experience. As many users have already seen in El Capitan"s public beta, it includes changes to the UI, along with new security features and access to new APIs.
El Capitan will arrive exactly two weeks after the release of iOS 9, the latest version of Apple"s mobile OS, which will roll out on September 16.
