Apple is focused on pushing its fourth-generation Apple TV with the Siri Remote and built-in App Store, but that doesn’t mean the company has forgotten about owners of the older third-generation Apple TVs.
Thursday, a minor over-the-air Apple TV 7.2.1 software update was released for the $69 third-generation Apple TV.
The firmware update can be applied through the Software Update mechanism in the device’s Settings menu.
Although this particular software update for the third-generation Apple TV has the same version number as the previous one (iOS 8.4.1), the build number has changed to “12H523” so this tells us that the update is most likely focused on under-the-hood improvements, bug fixes and other internal changes.
the security content of the Apple TV 7.2.1 update can be examined in Apple’s support document. We’ll update the post if additional information becomes available.
