Apple's Latest Operating System Update Dubbed 'El Capitan'

Apple Inc. (NASDAQ: AAPL) unveiled the latest version of its operating system at a developers' conference Monday, naming it after the 3,000-foot rock monolith El Capitan in Yosemite National Park.

Various features were outlined on a live blog offered by Apple concerning its annual Worldwide Developers Conference in San Francisco.

But The Wall Street Journal deemed the revamped operating system not much different than the last, OS X Yosemite.

Perhaps the system's most notable improvement is in speed.

Apps will launch 1.4 times quicker with the new system on average; app switching will be twice as fast, and opening a PDF in OS X's Preview app will happen four times as quick, according to WSJ.

Apple's Spotlight search tool will use natural language to hut for documents on a Mac and for other information on the Web.

WSJ also highlighted a new Safari feature that offers a mute button for audio from websites.

Re-sizable windows is also a prominent feature in El Capitan, according to Business Insider.

"Similar to Windows, you can now quickly set up two app windows side by side. Just click on the green button in the window's toolbar, choose which program you want running on the left on the screen, and then choose what you'd like running in the second window," Business Insider said.

El Capitan is available to developers immediately and through a public beta starting in July.

It will be free to the public this fall.
