It’s unknown as to exactly what this does, but it’s an AirTags firmware update and it might be helpful.
Apple on Wednesday released version 1.0.276 of its AirTags firmware, which is a revision to the update that was made available in June.
The updated AirTags 1.0.276 firmware has a build number of 1A287b, while the old firmware had a build number of 1A276d. The 1.0.276 firmware that came out in June added anti-stalking security enhancements, and this new version likely just refines these features.
Given that the firmware version itself has not changed, it’s impossible to tell the new firmware from the old firmware via the Find My app, nor will it be apparent when the firmware of the AirTags has been updated.
While there’s no way to force an AirTag to update, this can be performed over-the-air through a connected iPhone. To execute the update, place your AirTag within range of the iPhone, and wait for the firmware update to roll out to your device.
Users can also check your current AirTag firmware version through the Find My app.
If you’ve had a chance to try the revised firmware, please let us know about your experience in the comments.
