Download iOS 11 Beta 4 and macOS High Sierra Beta 4 now [direct links]

Apple released fourth beta releases iOS 11, macOS High Sierra 10.13, tvOS 11, and watchOS 4 to users who participate in developer beta programs.

The latest beta releases continue to develop and improve various operating systems Apple that are not in active development.

As usual, the easiest way to download the latest beta release is using the standard update mechanism. On iOS it is in the settings, on macOS in the Mac application App Store, on tvOS also in the settings, and on Apple Watch through the Watch app on iPhone. Always back up any device before installing any system software update.

Public betas like iOS 11 beta 4 will be available soon. New beta versions for developers are often released before the public release. Recently, the interval is no more than a few days. The public beta is one digit behind, which means the next public release will be 'beta 3', not 'beta 4', even though they are the same versions.

Initially, developer versions were supposed to be limited, only registered Developers Apple can participate. But now anyone can participate in testing programs iOS 11 public beta or macOS High Sierra public beta. Please note that beta versions of system updates can be very unreliable and contain many more bugs than final versions. Beta systems are best tested on devices that you don't use very often.

The final versions of both macOS High Sierra and iOS 11 will be released this fall.
