Apple today seeded the second beta of an upcoming OS X El Capitan update to developers for testing purposes, more than a week after releasing the first OS X 10.11.1 beta and one day before the scheduled public release of OS X El Capitan on September 30.
The new beta is available through the Software Update mechanism in the Mac App Store and through the Apple Developer Center.
The first beta of OS X 10.11.1 introduced support for Unicode 8 and new emoji like taco, burrito, cheese wedge, hot dog, middle finger, and unicorn head.
It is not clear what other improvements the first update to OS X El Capitan will bring, but it's likely to be a minor update that includes bug fixes and performance improvements for issues encountered following the operating system's official release. According to Apple's release notes, the beta offers stability, compatibility, and security improvements.
