Following today's release of the iOS 12.1.4 update that fixed the eavesdropping bug with group FaceTime on iPhone and iPad, Apple followed up with a similar update for Mac computers.
macOS Mojave 10.14.3
Following weeks of testing, Apple today released new software updates: iOS 12.1.3 for iPhone, iPad and iPod touch, iOS 12.1.3 for HomePod, macOS Mojave 10.14.3 for Mac, watchOS 5.1.3 for Apple Watch and tvOS 12.1.2 for the fourth-generation Apple TV and Apple TV 4K . While mostly about bug fixes that improve your security, these minor software updates are worth the time because they happen to boost the stability, performance and reliability of your devices.
Apple on Thursday seeded the fourth beta of iOS 12.1.3 to developers. The release comes just three days after the beta 3 rollout, and registered developers can install the update via the iOS over-the-air mechanism, or through Apple's Dev Center.
