Three weeks after releasing the first beta of OS X 10.11 El Capitan's third major software update, and 48 hours after seeding iOS 9.2.1 beta 2 to developers and public beta testers, Apple on Wednesday released a second beta of OS X 10.11.3 El Capitan.
It can be installed on machines running a prior beta through the Mac App Store's Updates tab and downloaded through Apple's portal for members of the Apple Developer Program.
The pre-release software is also available to public beta testers who signed up for Apple's Beta Software Program.
