Third Betas of iOS 11, macOS 10.13, and tvOS 11 Released to Developers

Third Betas of iOS 11, macOS 10.13, and tvOS 11 Released to Developers

macOS 10.13 High Sierra Beta 3

The macOS 10.13 High Sierra update – build 17A 306f – offers several new features and refinements, including a new Apple File System (APFS), a High Efficiency Video Codec (HEVC) and an updated version of Metal offering support for VR and external GPUs.

The latest beta has enabled initial Time Machine support, and AVKit has added routines for developers to include additional flexibility for content playback when multiple outputs are available.

iOS 11 Beta 3

The iOS 11 Beta 3 update – build 15A5318g – offers mainly under the hood fixes, including a fix for connection issues for Bluetooth accessories using Wireless iAP protocol. Using 3D Touch with data detectors (phone numbers, addresses, and such) now works

tvOS 11 Beta 3

The tvOS 11 beta update – build 15J5324f – has mostly behind the scenes changes, restoring the functionality of some third-party media apps. DirecTV Now users, such as myself, will have to wait for a fix for the streaming television app’s periodic crashing under both tvOS 11 and iOS 11.

Also released on Monday was a new beta of Xcode 9, build 9M174d. So far, Apple hasn’t released a new beta of watchOS 4. We’ll keep you posted.

Registered developers can download updates to the most recent betas by way of their registered devices’ update features. They can also be downloaded via Apple’s Developer Center.
