Apple Seeds Second OS X 10.11.3 El Capitan Beta to Developers and Public Beta Testers

Apple today seeded the second beta of an upcoming OS X 10.11.3 El Capitan update to developers and public beta testers for testing purposes, three weeks after seeding the first OS X 10.11.3 (http://www.macrumors.com/2015/12/16/apple-seeds-first-os-x-10-11-3-beta/) beta and a month after releasing OS X 10.11.2 (http://www.macrumors.com/2015/12/08/apple-releases-os-x-10-11-2/).





The second OS X 10.11.3 beta, build 15D13b, can be downloaded through the Apple Developer Center (https://developer.apple.com/osx/download/) or via the Software Update Mechanism in the Mac App Store for those who installed the first beta.

The first beta of OS X 10.11.3 did not include any noticeable outward-facing changes, suggesting the update will focus on security enhancements, performance improvements, and bug fixes to address issues that have been discovered since the release of OS X 10.11.2. Prior OS X El Capitan updates have also focused mainly on under-the-hood improvements.





We'll update this post with any changes that are discovered in the beta.
