Today, Apple released a revised version of the AirTag firmware, which was released to users for the first time last week. The internal version number of the new firmware is 1A291c, which is higher than the previous 1A291a.
At present, the specific content of the new firmware is unclear, and no new features have been discovered after the previous release. This firmware update may focus on bug fixes and other low-level improvements. Users can open the search application and select AirTag in the inventory to check the current firmware version.
It should be noted that the AirTag update is done wirelessly through the iPhone, and users cannot force it to update. To ensure that the update is complete, the user can place the AirTag within the connection range of the iPhone.
