Apple is rolling out a new version of its AirTags firmware (version number of 1.0.291 and a build number of 1A291a, up from 1A287b). 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.
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.
Checking your AirTag firmware version is a bit roundabout.
- Open the Find My application on your iPhone.
- Tap the Items tab in the bottom navigation bar.
- Select your AirTag from the list of displayed items by tapping on the name of the AirTag.
- Your AirTag’s serial number and firmware version should be displayed.
If your AirTag has not yet been updated, be patient. Just make sure your AirTag is in range of your iPhone and it should soon automatically update.
