Apple today released OS X El Capitan beta 3 to developers for testing purposes, just over two weeks after releasing the EI Capitan beta 2 and a month after unveiling the new operating system at its 2015 World Wide Developers Conference.
The update is available through the software update mechanism in the Mac App Store and through the Apple Developer Center.
OS X El Capitan largely builds on the features introduced with OS X Yosemite, focusing on improving performance and user experience. The improvements in El Capitan have made a number of apps and processes on the Mac much faster, and the introduction of Metal makes system-level graphics rendering 40 percent more efficient.
This EI Capitan includes a revamped Mission Control feature and new Split view feature for using two full screen apps at once, deeper functionality for Spotlight and several new features for safari which includes pinned sites for housing frequently visited websites and a universal mute button that quiets all tabs. Currently OS X 10.11.EI Capitan is available to the registered developers and the Apple plans to offer a public beta of the software in July. Following testing, El Capitan will see a final release in the fall of 2015.
