Apple released the iOS 12.4, macOS Mojave 10.14.6, tvOS 12.4, and watchOS 5.3 software updates for all supported devices, adding more security improvements and bug fixes.
After a few weeks of development, the iOS 12.4 (build 16G77), macOS Mojave 10.14.6 (build 18G84), tvOS 12.4 (build 16M568), and watchOS 5.3 (build 16U569) software updates are here and ready for download via OTA (Over-the-Air) update mechanism on all supported iPhone, iPad, Mac, Apple TV, and Apple Watch devices.
As for the changes included in this new maintenance releases, we can mention that iOS 12.4 introduces an iPhone migration feature that lets users wirelessly transfer their data from an old iPhone device to a new one during the first-time setup process. Of course, for this to work, the newer device needs to run the iOS 12.4 release.
