Apple released a firmware update for AirTags earlier this week but it was not clear what the new build brought to the table. Now, the company has released a new support document, suggesting that it has tuned the sound made by unknown AirTags attached to you or your belongings. Scroll down to read more details on the subject.

Apple's item-tracking accessory can be used for various purposes like tracking your luggage when traveling in case it gets lost. We recently covered a story where a traveler presented a PowerPoint presentation to an Airline, asking about his lost bags that he tracked using AirTags. However, Apple has placed appropriate precautionary measures if someone attached an AirTag to you or your belongings. The AirTag will make a sound that will allow you to find it. Now, with the latest firmware update, Apple has tweaked the tune or sound made by the unknown AirTag.
