Apple has released a series of beta builds for system software, including iOS 9.3.2 beta 1 for iPhone, iPad, and iPod touch, OS X 10.11.5 beta 1 for Mac, WatchOS 2.2.1 beta 1 for Apple Watch, and tvOS 9.2.1 beta 1 for Apple TV. The point release beta updates are primarily focused on bug fixes and feature enhancements.
The current beta builds are available for developer testing, but will likely be released in the public beta programs shortly.

The beta update is available now for users who are participating in the developer beta testing program through the Software Update mechanism on their devices, or through the Apple Developer Center.
A first beta of OS X 10.11.5 for Macs arrives as build 15F18b and includes focuses on bug fixes and improvements to El Capitan. Mac users in the beta testing program can find the download through the App Store or through the OS X Developer Center on Apple.com.
