Beta 2 of iOS 11.4.1 and macOS High Sierra 10.13.6 Released for Testing
Apple has released the second beta versions of macOS 10.13.6 High Sierra and iOS 11.4.1 for user enrolled in the beta testing programs for current generation Apple system software.
iOS 11.4.1 beta 2 is expected to be a bug fix update primarily, as no new features or major changes are expected in the iOS 11.x software channel now that iOS 12 is under active development.
macOS 10.13.6 High Sierra beta 2 is also expected to be focused primarily on bug fixes and refinements, as the next generation of macOS system software versioned as macOS Mojave 10.14 is currently under development.
Separately, new beta builds of tvOS and watchOS are available for those who like to run beta software on their Apple TV and Apple Watch.
Note that if you currently have downloaded macOS Mojave beta 1 or iOS 12 beta 1 then the beta versions of macOS High Sierra or iOS 11.4.1 will not be visible for you. If you are running a newer version of system software but want to run the older beta releases, you would need to downgrade iOS 12 back to iOS 11 and then enroll back into the iOS 11 beta testing program. Likewise, for macOS Mojave users they would need to downgrade from the macOS Mojave beta then reinstall the macOS High Sierra beta to have access to the macOS High Sierra beta.
Apple usually goes through several beta versions before unveiling a final build to the general public, suggesting that iOS 11.4.1 and macOS High Sierra 10.13.6 may be finalized sometime in the coming months. Meanwhile, release dates for macOS Mojave and iOS 12 are set for fall of this year.
The current final versions of macOS High Sierra system software is currently 10.13.5 and for iOS system software is iOS 11.4.
