Apple has released an emergency software patch after researchers uncovered a security flaw that could allow hackers to secretly install spyware on your Apple devices even if you do nothing, not even click on a link. The spyware can then eavesdrop or steal data from your device. All of Apple’s operating systems, including those for iPads, Macs and Apple Watches, are vulnerable. Although it’s unlikely that hackers will target average users, any Apple device is vulnerable and the iOS update is recommended for everyone. To update your iPhone or iPad: Go to Settings. Tap General. Tap Software Update. Plug in your device or make sure it has 50% battery life or more. Tap “Install Now.”
