Apple released OS X EI Capitan beta 3 for the developers and also for public testers, company released this update one week after releasing the second OS X 10.11.1 beta and a week after the public release of OS X El Capitan on September 30.
Beta 3 for OS X EI Capitan comes with a build 15B30a and the update is available through the Software Update mechanism and the developers can grab the build from the Mac Developer Resource Center, while both developers and beta software program members can download the update from the Mac App Store.
The first beta of OS X 10.11.1 introduced support for a range of new emoji included in Unicode 8, like cheese wedge, taco, burrito, popcorn, middle finger, unicorn head, and more. Other betas appear to include under-the-hood fixes that are not immediately apparent.
It is not clear what the first update to OS X El Capitan will bring to the new operating system aside from updated emoji, but probably this might be a minor update that includes bug fixes and performance improvements and some enhancements for issues encountered following the operating system’s official release. According to Apple’s release notes, the beta offers stability, compatibility, security improvements and many more.
