Apple has released an update to AirTags firmware – moving from internal build number 1A291c to 1A291a. As MacRumors noted, the release comes just a week after the previous iteration was released.
We don’t know what’s included in the new firmware and no new features were found following the first release, so it likely focuses on bug fixes and other under-the-hood improvements. There is no way to force an AirTag update, as it’s something that’s done over-the-air through a connected iPhone. To make sure the update happens, you can put your AirTag in range of your iPhone, but you have to wait for the firmware to roll out to your device.
