Apple today released the third beta of OS X 10.11 El Capitan to developers for testing purposes, just over two weeks after releasing the second El Capitan beta and a month after unveiling the new operating system at its 2015 Worldwide 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. Behind-the-scenes 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.

Along with a new systemwide font, El Capitan includes 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 currently only available to registered developers, but 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.

What's new in OS X El Capitan beta 3:

Two-Factor Authentication - iOS 9 and OS X 10.11 El Capitan include an entirely revamped two-factor authentication system.

Photos app - As in iOS 9 beta 3, there are new albums for selfies and screenshots in the Photos app in El Capitan beta 3.

If beta 3 never happened and beta 2 became the public release, it would still be better than Yosemite. And that says a lot, because I never had problems with Yosemite.

iMac (Mid 2007 or newer) MacBook Air (Late 2008 or newer) MacBook (Late 2008 Aluminum, or Early 2009 or newer) Mac mini (Early 2009 or newer) MacBook Pro (Mid/Late 2007 or newer) Mac Pro (Early 2008 or newer) Xserve (Early 2009) Notes and Known Issues

Installation Note

After upgrading to OS X El Capitan Developer Beta, applications that write to protected/system locations may no longer function correctly.

Installation
Known Issues

Directly upgrading from OS X Lion or earlier to OS X El Capitan Developer Beta 3 is not recommended.

Selecting the ‘Do It Later’ option will not install updates for Standard user Accounts.

Some systems may fail to boot after installation if USB devices are attached. Remove USB devices before booting to resolve.

AppleID
Some Apple ID accounts will be offered the option to upgrade to using two-factor authentication.

Known Issues

Attempting to enroll in two-factor authentication after installing OS X El Capitan Beta 3 may display an error regarding access to iCloud secure data. The iCloud Preference Pane can be used to complete enrollment. After enabling two-factor authentication users may be prompted to re-enable two-factor authentication again.

If you have two-factor authentication enabled, you may not be able to sign into services using OS X El Capitan or iOS 9 beta 2 or earlier. If you enable two-factor authentication, iTunes purchases on Mac and Windows will require you to append a 6-digit code to the end of your password on every purchase. The 6-digit code will automatically be sent to your iOS 9 or OS X El Capitan devices.

When there is only a single trusted device using two-factor authentication, you will need to generate a code in the iCloud Preference Pane when requested.

If you disable two-factor authentication and set a new password at iForgot.apple.com, the password requirements are not indicated so your password may not be accepted. Please ensure your password meets the following requirements:

Have at least one lower case character * Have at least one capital letter * Have at least one number * Your password must not contain more than two consecutive identical characters * Not be the same as the account name * Be at least 8 characters * Not be a common password

You cannot manage your two-factor authentication trusted devices at appleid.apple.com. Devices can be managed in the iCloud Preference Pane.

Known Issues

Upgrades of existing iPhoto / Aperture libraries to Photos libraries will not succeed in OS X El Capitan Beta 3. Upgrade your iPhoto / Aperture library to Photos on a pre-OS X El Capitan Beta 3 system or create a new Photos library and import the assets into this new library.

Has anyone else with a 2014 13" rMB felt like system audio has been clearer and louder since El Cap Beta 1? I stopped using Boom 2.
