Apple recently released new development builds for the upcoming iOS 11.1 Beta 5, macOS High Sierra 10.13.1 , and tvOS 11.1 operating systems to registered developers and public beta testers.
iOS 11.1 Beta 5, macOS High Sierra 10.13.1, and tvOS 11.1 Beta 4 are now available to install from your Apple Developer account if you're an app developer. Public beta testers can also install iOS 11.1 Public Beta 5, macOS 10.13.1 High Sierra Public Beta 5, and tvOS 11.1 Public Beta 5 on their devices.
To install the macOS High Sierra 10.13.1 Beta 4 or Public Beta 4 (17B45a) update, simply run the macOS Developer Beta Access Utility to download the latest macOS 10.13 beta. On the other hand, the iOS 11.1 Beta 5 or Public Beta 5 (15B93) and tvOS 11.1 Beta 4 or Public Beta 4 (15J5582a) updates can be installed via the OTA update system.
This time, Apple has decided not to update the watchOS 4.1 OS for Apple Watch devices. The same goes for the Xcode 9.1 IDE, which contains the SDKs (Software Development Kits) for the latest iOS, macOS, tvOS, and watchOS operating systems.
iOS 11.1 Beta 4 / Public Beta 4 users are advised to update their iPhone, iPad and iPod touch devices to beta 5 / Public Beta 5. macOS High Sierra 10.13.1 Beta 3 or Public Beta 2 users should update their Macs to Beta 4 / Public Beta 4. Finally, tvOS 11.1 Beta 3 users should update their Apple TV 4K or Apple TV (4th generation) devices to Beta 4.
