Fifth iOS 11.1, fourth tvOS 11.1 and macOS High Sierra 10.13.1 developer betas arrive [u]

Apple has again short-cycled the developer testing release cycle with a new fifth beta of iOS 11.1 accompanying fourth betas of macOS High Sierra 10.13.1 and tvOS 11.1.

The new software and accompanying build numbers are as follows:

  • macOS High Sierra 10.13.1 beta 17B45a
  • tvOS 11.1 beta 15J5582a
  • iOS 11.1 beta 15B93

The latest iOS 11.1 beta is an increment of only one digit from the previous release. It is unclear at this time what has been changed or added.

A number of features were absent from the public release of iOS 11, including AirPlay 2 and Apple Pay Cash.

Apple's iOS 11.1 is likely to arrive around the time that the iPhone X, ships to customers on Nov. 3.

Apple last updated macOS High Sierra on Oct. 6 with a supplemental release designed to patch critical Disk Utility and Keychain vulnerabilities. The update also fixed a mail deletion issue in Mail and a graphical bug seen when using Adobe InDesign.

Apple's next-generation Mac operating system debuted in September with marquee features like the new Apple File System (APFS), support for Metal 2 graphics, H.265 integration, an improved Safari experience and more.

Update: Apple has also released public versions of the beta software.
