Yesterday Apple released iOS 12.3.2 for owners of iPhones 8 Plus to fix a specific issue that affected Portrait Mode (photos didn't come out with the desired effect); today, the company made available the iOS 12.4 beta 4 (build 16G5046d) for developers two weeks after beta 3 release.
New even for this version, only support for Apple card, which will be released in the United States soon. Otherwise, we are talking “only” about bug fixes and general improvements.
Along with the fourth test version of iOS 12.4, the company also made available the macOS Mojave 10.14.6 beta 2 (compilation 18G48f), the watchOS 5.3 beta 3 (16U5545c) and the tvOS 12.4 beta 3 (16M5545c).
Parallel to these versions, Apple has also released the first beta versions of iOS 13, iPadOS 13, macOS Catalina 10.15, watchOS 6 and tvOS 13 for testing that, do not get lost in numbers! 🤯
These new builds of iOS, macOS, and tvOS should soon be painting on the Apple Beta Software Program, for whom the developer will also be testing.
