Apple just seeded its second beta release of OS X 10.11.3 to both public beta testers and developers as it prepares for the upcoming public release.
Apple released the first beta of 10.11.3 on the Mac App Store mid-December following the public release of OS X El Capitan 10.11.2 earlier that month.
The company didn’t include any release notes with the first two pre-release versions of 10.11.3, which means the update should focus on performance improvements and bug fixes instead of major new features or enhancements.
As always, you can download the OS X 10.11.3 El Capitan beta 2 through the Mac App Store.
