Apple has released the third beta for OS X 10.11.2 El Capitan to its registered beta testers just one day after it seeded the third beta version of the operating system to developers.

The release of the third beta also came just two weeks after Apple seeded the first beta for the OS version, and only three weeks after the public release of the final OS X 10.11.1 El Capitan.

Users that have registered as participants in the beta testing program of Apple could download the third beta for OS X 10.11.2 El Capitan through the Software Update system found in the App Store for Mac. For users that would like to sign up as a participant in the beta testing program, they can do so through the dedicated website.

The first two beta versions for OS X 10.11.2 El Capitan did not contain any standout updates or changes, with the minor update mostly likely only including security improvements, bug solutions and performance tweaks to address the problems that have been reported with Apple's release of OS X 10.11.1 El Capitan.

The release notes of Apple for the beta versions for developers ask the testers to put most of their focus on the operating system's graphics, Calendar, Wi-Fi, Notes, USB, Spotlight and Photos functions, hinting on where Apple made improvements to the OS.

OS X 10.11.1 El Capitan provided a minor update to the operating system's performance, along with several significant bug fixes. The compatibility with Microsoft's Office 2016 apps also received an improvement.

The latest publicly-released version of the operating system also improved the installer reliability for upgrading to OS X El Capitan, along with fixes to issues associated with the Mail function and Audio Unit plug-ins. The reliability for the VoiceOver function has also been improved and last but not least, the operating system upgrade also added more than 150 new emojis.
