Following the reveal of OS X El Capitan, the company has released OS X El Capitan Beta 1 just over a couple weeks ago, and now Apple has released yet another build of OS X El Capitan, OS X El Capitan Beta 2 build number 15A204h, to developers for download and testing.
Alongside OS X El Capitan Beta 2, Apple has also released OS X Server 5.0 beta 2 as well as Apple Configurator 2.0 beta 2. OS X El Capitan Beta 2 is considered a minor update since it includes bug fixes as well as under-the-hood features such as improvements in stability, compatibility, and security of your Mac.
You can get OS X El Capitan Beta 2 through Software Update or the Mac Dev Center for registered developers, while registered public beta testers will start receiving OS X El Capitan Betas starting next month.
