Just one day after developers received the fifth beta build of iOS 11, Apple has released the same beta update to public testers, bringing a number of UI changes and bug fixes with it.
iOS 11 public beta 4 and macOS High Sierra public beta 4 are now available to download for all members of Apple’s public beta software testing program. You can also download the new software directly to your Mac, iPhone or iPad if you have the previous public beta installed.
