tvOS 11.1 Patches KRACK in Apple TV

by Josh Centers

Apple has released tvOS 11.1 [1] for the fourth-generation Apple TV and Apple TV 4K, expanding the availability of the TV app to Norway and Sweden. You can update your Apple TV by going to Settings > System > Software Updates.

tvOS 11.1 also includes five security fixes [2] — most notably to correct the KRACK Wi-Fi vulnerability discussed in “Wi-Fi Security Flaw Not As Bad As It’s KRACKed Up To Be [3]” (17 October 2017).

We haven’t heard of any issues with the tvOS 11.1 update yet, but it’s never a bad idea to wait a day or two to make sure none crop up.
