Last week iOS 14.7 appeared, adding features including support for Apple’s magnetic battery pack. Unfortunately, the update also interrupted the “Unlock with iPhone” feature that Apple Watch wearers used for easy access to their wristwear. Now, another update is going out to fix that.

Apple releases iOS 14.7.1 to fix Apple Watch unlocking and a zero-day exploit

Last week iOS 14.7 appeared, adding features including support for Apple’s magnetic battery pack. Unfortunately, the update also interrupted the “Unlock with iPhone” feature that Apple Watch wearers used for easy access to their wristwear. Now, another update is going out to fix that.

However, even if you don’t have an Apple Watch, you should still install iOS 14.7.1 (and for Mac owners, macOS 11.5.1) as soon as you can, because security notes from Apple reveal that the two updates it pushed today fix flaws that are already being exploited in the wild. The memory corruption issues in Apple’s desktop and mobile operating systems have been assigned the same vulnerability ID and attributed to an anonymous researcher.
