Apple issues fourth beta of OS X 10.11.2 to developers for testing

Members of Apple's registered developer program can now access the fourth pre-release beta of OS X 10.11.2, a forthcoming maintenance and security update for its OS X El Capitan operating system.

Identified as build 15C47a, the new beta was released on Apple's developer website and via the Mac App Store on Tuesday. The forthcoming update is not expected to hold major feature additions, but should bring the usual assortment of backend.

Developers have been asked to focus their testing on Calendar, graphics, Mail, networking, Notes, Photos, Spotlight, USB and Wi-Fi, features under constant refinement. The company has been on a weekly schedule in pushing out OS X betas, the most recent of which contained minor changes to the same focus areas.

Apple last month formally released the OS X 10.11.1 update to address issues with Office 2016, Mail, VoiceOver and more. The software also included unspecified performance enhancements and more than 150 new emoji characters.
