Apple released OS X 10.11.2 beta 5 to the developers and testers, two weeks after seeding the fourth beta and more than a month after releasing OS X 10.11.1, the first OS X El Capitan update, to the public.
This beta comes with a build 15C48a and available through the Software Update mechanism in the Mac App Store and can be downloaded through the Apple Developer Center. Public beta testers can download the beta through the Mac App Store.
OS X 10.11.2 appears to be an under-the-hood update as the four previous betas have not included any apparent outward-facing changes. OS X 10.11.2 is likely to include bug fixes, security enhancements, and performance improvements to address problems that have popped up since the release of OS X 10.11.1.
Apple’s release notes for OS X 10.11.2 have asked developers to focus on Networking, Graphics, Mail, Wi-Fi, Calendar, USB, Notes, Photos, and Spotlight.
Finally, What changes will come with the public release of OS X 10.11.2 are not yet clear, though it will likely contain a number of bug fixes and performance improvements to the overall OS X experience.
