In addition to iOS 9.2.1 beta 1, Apple has released OS X 10.11.3 developer beta 1 through the Mac App Store.
The pre-release software doesn’t contain any release notes or focus areas, but likely includes further performance improvements and bug fixes. The first OS X 10.11.3 developer beta follows last week’s public release of OS X El Capitan 10.11.2 which had its own list of small fixes for the Mac operating system. The update is a roughly 650 MB download.
