Apple has just seeded the second beta of OS X 10.11.6 beta to public beta testers, one day after releasing the second OS X 10.11.6 beta to developers. OS X 10.11.6 has been in testing since May 23 and the second beta comes three weeks after the public release of OS X 10.11.5, the fifth update to the El Capitan operating system.
OS X 10.11.6, like most of the previous updates to the El Capitan operating system, appears to be minor in scale, focusing mainly on bug fixes and security improvements that are not immediately obvious to testers and developers. No outward-facing changes or major bug fixes were discovered in the first two developer betas.
The new software is available through the Updates tab in the Mac App Store for machines that are running the first public beta. Mac users who want to join the program can sign up on Apple’s beta testing website.
