OS X El Capitan (el-KAP-i-TAN) (version 10.11) is the upcoming twelfth major release of OS X, Apple Inc.'s desktop and server operating system for Macintosh computers. It is the successor to OS X Yosemite and focuses mainly on performance, stability and security.[1] Following the California landmark-based naming scheme introduced with OS X Mavericks, El Capitan was named after a rock formation in Yosemite National Park.

The first beta of OS X El Capitan was released to developers shortly following the 2015 WWDC keynote on June 8, 2015.[2] The first public beta was made available on July 9, 2015.[3] OS X El Capitan was announced to be available to end users in late 2015 as a free upgrade through the Mac App Store.

Features

OS X El Capitan includes features to enhance the design and usability of OS X as well as performance and security improvements. Apple states that opening PDFs is 4x faster, viewing messages in Mail is 2x faster, app switching is 2x faster, and launching apps is 1.4x faster than in OS X Yosemite.[4][5]

Window management

OS X El Capitan introduces support for snapping two windows side by side to create a split view, similar to the snap-assist feature in Windows 7 (and later) and several Linux desktop environments, such as GNOME.[6] OS X El Capitan improves Mission Control to incorporate this feature across multiple spaces. It also comes with a feature that enables users to spot the pointer more easily by enlarging the pointer while shaking the mouse or swiping a finger back and forth on the trackpad.[7]

Applications

OS X El Capitan adds multi-touch gestures to applications like Mail and Messages that allow a user to delete or mark emails or conversations by swiping a finger on a multi-touch device, such as a trackpad. OS X also analyses the contents of individual emails in Mail and uses the gathered information in other applications, such as Calendar. For example, an invitation in Mail can automatically be added as a Calendar event.

Apple Maps in El Capitan shows public transit information similar to Maps in iOS 9.[4] This feature will be limited to a handful of cities upon launch: Baltimore, Berlin, Chicago, London, Los Angeles, Mexico City, New York City, Paris, Philadelphia, San Francisco, Shanghai, Toronto and Washington D.C.

The Notes application receives an overhaul, similar to Notes in iOS 9. Both applications will have more powerful text-processing capabilities, such as to-do lists (like in the Reminders application), inline webpage previews, photos and videos, digital sketches, map locations and other documents and media types. Notes will replace traditional IMAP-based syncing with iCloud, which offers better end-to-end encryption and faster syncing.[8]

Safari in El Capitan allows users to pin tabs for frequently accessed websites to the tab bar, similar to Firefox and Google Chrome. Users will be able to quickly identify and mute tabs that play audio without having to search for individual tabs. Safari will also support AirPlay video streaming to an Apple TV without the need to broadcast the entire webpage. Safari extensions shall be hosted and signed by Apple as part of the Apple Developer programme and Safari will receive native support for content blocking, allowing developers, among other things, to block advertisements without JavaScript injection.[9]

Spotlight is improved with more contextual information such as the weather, stocks, news and sports scores. It will also be able to process queries in natural language. For example, users can say "Show me pictures that I took in Yosemite National Park in July 2014" and Spotlight will use that request to bring up the corresponding info.[10]

Technologies

Metal

Main article: Metal (API)

OS X El Capitan will support Apple's graphics API Metal, after its introduction in iOS 8. While similar to Metal on iOS, Metal on OS X will take advantage of the extra performance capabilities of Macs to deliver fast performance in games and professional applications. The overall speed of OS X El Capitan has been greatly improved from that seen in OS X Yosemite.[11]

System Integrity Protection

Main article: System Integrity Protection

OS X El Capitan will have a new security feature called System Integrity Protection (also known as "rootless"[12][13][14]) which protects certain system processes, files and folders from being modified or tampered with by other processes, even when executed by the root user. Apple says that the root user can be a significant risk factor to the system's security, especially on systems with a single user account on which the user is the de facto administrator. System Integrity Protection is enabled by default, but can be disabled.[15][16]

System requirements

All Macintosh products capable of running OS X Yosemite are supported by El Capitan, which includes all models supported by OS X Mavericks and most models supported by its predecessor OS X Mountain Lion.[17] However, not all features are available for each model. Apple notes that Metal is available on "all Macs since 2012".[18] It is speculated that the GPU must at least support OpenGL 4.3.[19]

The following models are compatible with OS X El Capitan:[20]

Reception

The initial press and developer reception upon announcement at WWDC 2015 has been generally positive with many reviewers citing that these new performance improvements in iOS 9 and OS X El Capitan were welcome,[21][failed verification] especially since the previous releases (iOS 8 and OS X Yosemite) had some issues with performance, particularly with older devices.[22] However, some journalists have noted El Capitan's lack of new and innovative features, labeling OS X El Capitan as a relatively minor upgrade compared to previous releases such as El Capitan's predecessor, OS X Yosemite. Apple has received praise for the increased integration between all its various platforms.[citation needed] For example, many journalists have noted that the multitasking features and applications like Notes are the same across platforms.[citation needed]
