Apple seeds macOS Mojave 10.14.6 beta 5 to testers [features and changes]

Apple has released macOS Mojave 10.14.6 beta 5 with under-the-hood improvements and bug fixes. The update is now available for registered developers, while a public beta will be available soon.

macOS Mojave 10.14.6 beta

Apple had previously released macOS Mojave 10.14.5 with AirPlay 2 support for Smart TVs, Apple News+ app update, audio latency improvements for 2018 MacBook Pros and various other bug fixes and improvements. macOS TV app was not part of this update and will be released this fall.

In a surprising move, Apple released this new beta just a couple of weeks before WWDC 2019, where the company will be announcing macOS Mojave 10.15, the next major update to their popular desktop operating system. macOS Mojave 10.15 will ship with Siri Shortcuts and Screen Time, a Mac to iPad display extension feature, new Music, Podcasts, TV and Books apps and much more.

Apple has also released iOS 12.4, watchOS 5.3 and tvOS 12.4 as betas.
