In recent weeks, Apple has been pushing rapid updates for OS X El Capitan, all of which have focused on under-the-hood performance improvements and bug fixes to optimize the operating system ahead of its public debut. Few design changes have been made in the most recent betas, but beta 7 includes some minor tweaks like a new Safari welcome screen, a new color for the El Capitan logo in “About This Mac,” and a setting to disable the “Shake mouse pointer to locate” feature.


OS X El Capitan is designed to improve features introduced with OS X Yosemite, focusing on performance and user experience. A number of apps and processes on the Mac are much faster with El Capitan, and the introduction of Metal for Mac brings system-level graphics rendering that’s 40 percent more efficient.

As for user experience, El Capitan includes a new systemwide San Francisco font, a revamped Mission Control feature, a new Split View feature for using two full-screen apps at once, deeper functionality for Spotlight, and several new features for Safari, including Pinned Sites for housing frequently visited websites and a universal mute button that quiets all tabs.

OS X 10.11 El Capitan is available to both registered developers and public beta testers. Apple plans to release El Capitan to the public in the fall.
