Apple releases macOS Catalina 10.15, watchOS 6.2 and tvOS 13.4

Together with iOS / iPadOS 13.4, Apple has made publicly available the final versions of macOS Catalina 10.15.4, watchOS 6.2 and tvOS 13.4 . As for the Mac software update, it comes a couple of months after the release of macOS Catalina 10.15.3.

Among the main innovations we point out the introduction of the "Screen Time Communication Limits" function, already seen with iOS 13.3.1. This allows parents to limit their children to certain reachable Facetime contacts, phone, messages and iCloud. It improves accessibility, thanks to the introduction of a mouse control function with the head, using the Mac camera. In addition, the lyrics arrive in Apple Music in real time.

As for watchOS 6.2, support for in-app purchases arrives through the App Store directly from Apple Watch, in addition to the resolution of some bugs. Finally comes tvOS 13.4 for Apple TV of the fourth and fifth generation, what at the moment seems to be the update with less news than the others, in fact we only find corrections and performance improvements.

All new operating systems are available for public download on compatible devices, in the next few hours we will better analyze the news and in case we will proceed to further investigations.
