Apple has a supplemental macOS 10.14.3 update available right now for all owners of compatible Mac hardware. The Cupertino-based company hasn't been able to hide from the recent furor around its Group FaceTime bug and this supplemental update is designed to patch that flaw on all Mac hardware.
Apple has a slew of new releases intended for those non-iPhone owners as well. The Cupertino-based fruit company has just flipped the internal release switch on the final version of watchOS 5.1.3, tvOS 12.1.2, and macOS 10.14.3.
