Apple today seeded the fourth beta of the OS X El Capitan 10.11.1 update to developers and public beta testers for testing purposes, just one week after releasing the third OS X 10.11.1 beta and two weeks after the 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.
OS X 10.11.1, like iOS 9.1, includes support for a range of new emoji like cheese wedge, taco, burrito, popcorn, middle finger, unicorn head, and more. New emoji were introduced in the first OS X 10.11.1 beta. Subsequent betas have not included any other outward-facing changes.
It is unknown what the first update to OS X El Capitan will bring aside from updated emoji, but as a minor .1 update, it’s likely to focus primarly on bug fixes and performance improvements for issues encountered following the operating system’s official release. According to Apple’s beta release notes, OS X 10.11.1 offers stability, compatibility, and security improvements.
