Two weeks after Monday, Apple today released the third beta versions of iOS 12.3 (compilation 16F5139e) of macOS Mojave 10.14.5 (18F118d) of watchOS 5.2.1 (16U5101c) and tvOS 12.3 (16M5139a).
In addition, Apple has also made available the Apple TV Software 7.3 beta 2 (12H833 compilation)
As we commented, the first test version of iOS 12.3 and tvOS brought the revamped Apple TV app.
These new builds of iOS, macOS, and tvOS should soon paint on the Apple Beta Software Program as well. And, as always, if more relevant news comes, we will inform you here. 😉
