Apple started pushing out an AirTags Firmware Update for AirTags earlier this week, and while it wasn’t apparent what changes were included at the time, Apple has now revealed in a new support article that the update adjusts the sound emitted by unknown AirTags found to be traveling with you.
Since their release, Apple has made various adjustments to the way AirTags work in order to address concerns about the trackers being used for stalking. Apple said in February that it will be making a number of adjustments to address stalking issues, with some of the improvements going live in March with iOS 15.4 and others arriving later.
One of the later changes was to use more of the strongest tones in an unknown AirTag’s tone sequence to assist locate it more easily, and that appears to be what this week’s firmware upgrade includes.
Although it isn’t stated in the release notes, Apple is releasing this software in stages, and there is no way to compel your AirTags to upgrade. The upgrade was only available to 1% of AirTag users when it began rolling out on Tuesday, but that number will climb to 10% on May 3 and 25% on May 9, and it will be available to everyone on May 13.
