Apple will release OS X El Capitan today (September 30), the latest major iteration of its operating system for Mac.

The update will be free to users, as has been the case for a number of years now.

Since El Capitan’s initial unveiling at WWDC in June, updates have been few and far between. From that presentation, however, we know that Apple has avoided any large strides in functionality. It appears that, like the recent updates to iOS 9, El Capitan will focus on usability and efficiency.

Users that were disappointed by the patchy reliability of features in last year’s OS X Yosemite will welcome this with open arms.

The major upgrades include an update to window management including Split View, which automatically positions windows.

Meanwhile, updates to Spotlight search means that users can now use natural language to find an email, or a file. Furthermore, Smart Suggestions and the addition of swipe-style gestures signals a drift towards a more iOS-like functionality.

El Capitan supports all Macs introduced in 2009 and later, and some models introduced in 2007 and 2008.
