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.
A fourth beta of the upcoming bug-fix tvOS 12.1.1 software update for the fourth and fifth-generation Apple TV is now available for developer testing. The over-the-air update with build number 16K5045a can be downloaded and installed on your Apple TV by using Apple's standard Software Update mechanism within the Settings app. The standalone installer is available through Apple's Development Center portal.
Apple has released iOS 12.1, watchOS 5.1, and tvOS 12.1 to the public. The updates arrive on the same day as Apple’s “There’s more in the making” event, which saw the arrivals of a new MacBook Air, Mac mini, and iPad Pro.
