Beta 2 of iOS 11.2 and macOS 10.13.2 Available to Download
Apple has released iOS 11.2 beta 2 for iPhone, iPad, and iPod touch users enrolled in the beta testing program, along with macOS High Sierra 10.13.2 beta 2 for Mac users participating in the beta programs.
The initial beta builds are for those in the developer testing programs, but public beta versions typically follow soon after.
Additionally, watchOS 4.2 beta 2 has been released for those who like to run beta software on Apple Watch, and tvOS 11.2 beta 2 for Apple TV beta testers.
Those enrolled in the beta testing programs can download the latest versions from the software update mechanisms on their respective devices. In iOS, that is achieved through the Settings app, in macOS via the Mac App Store, Apple Watch via the paired iPhone Watch app, and for tvOS through the Apple TV Settings app.
The new iOS 11.2 beta release presumably focuses on bug fixes and feature enhancements, but it also includes multiple new wallpapers.
macOS High Sierra 10.13.2 beta also likely focuses mostly on bug fixes and minor enhancements.
