Apple has released a beta version of iOS 12.4 and MacOS Mojave 10.14.6 for users who are beta testing the current generation of system software releases.
These beta versions are different from current beta programs for iOS 13, iPadOS 13 and MacOS Catalina. However, the public beta version of iOS 13 and iPadOS 13 and the public beta version of MacOS Catalina became available for download today.
In iOS 12.4 or MacOS Mojave 10.14.6, no major new features are expected, although iOS 12.4 may include support for a future Apple Card credit card. Instead, it is likely that software updates will be aimed at correcting errors and clarifications in operating systems and are likely to include security updates as well.
IPhone and iPad beta testers can find iOS 12.4 beta 5, available for download in the Software Update section of the Settings application.
MacOS Mojave 10.14.6 beta 3 can be downloaded from the software update control panel in System Preferences.
Always back up your Mac or iOS device before installing any system software, especially for beta versions.
Apple announced that the Apple Card will appear in the summer of 2019.
