Apple is rolling out a new version of its AirTag firmware. The refreshed firmware has a build number of 2A73, up from 2A61, which was released last October. While there is no way to force your AirTag to update its firmware, there is a way to see if it has been updated to the latest version.
Today’s firmware release will be rolling out on a staggered basis. 1% of users will get the update today, and then it will expand to 10% of users on March 26. On April 2, the update will expand to 25% of users, and then it will be available to all on April 9.
AirTag firmware updates install automatically when an AirTag is in range of your iPhone. The process is similar to how Apple updates the firmware of its AirPods lineup.
To check your AirTag’s firmware version, do the following.
