Apple has just seeded the third beta of OS X 10.11.6 El Capitan to developers and public beta testers for testing purposes, two weeks after releasing the second OS X 10.11.6 beta and more than a month after the public release of OS X 10.11.5. OS X 10.11.6 has been in testing since May 23.
OS X 10.11.6, like OS X 10.11.5 and the El Capitan updates that came before it, focuses mainly on performance improvements and bug fixes rather than outward-facing changes. According to Apple’s release notes, the update improves the stability, compatibility, and security of Macs.
The latest beta version for OS X El Capitan 10.11.6 is available through the Update tab in the Mac App Store on a computer running the first beta. It’s also available through the Apple Developer Center.
No obvious changes or bug fixes were found in the first two betas, but we’ll update this post should anything new be discovered in the third beta. Apple has also started testing macOS Sierra, the next-generation Mac operating system set to be released this fall.
