Along with releasing iOS 11.2.5 to the public, Apple’s watchOS 4.2.2 and tvOS 11.2.5 can be downloaded now.
Both the Apple TV and watchOS software feature behind-the-scenes improvements and other bug fixes.
On your Apple Watch, download the software from the Watch app and then select General > Software Update from the My Watch tab. Any watch will need to have more than 50 percent power, connected to a Wi-Fi network, and placed on a charger.
To update an Apple TV, if you don’t have automatic software updates turned on, go to Settings > System > Software Updates.
