Apple has just confirmed in a support document that the updated AirTag firmware rolled out this week includes a tuned tracking sound that makes it easier to detect any unwanted AirTags (via MacRumors).
Introduced in the latest AirTag firmware 1.0.301 is a tuned unwanted tracking sound that allows for easier location of an unidentified AirTag that may be tracking you without your knowledge.
Apple is continuing to make changes and updates to its AirTags amid criticism that the device is being used to stalk people. Earlier this year, the company announced it would address these concerns in future firmware updates, with some changes also rolled out last month with iOS 15.4.
