In this web content, the author shares their personal experience with their MacBook Air becoming a “worthless brick” after going through airport security and swapping laptops with a stranger. The author explains how they were eventually contacted by someone in the United Arab Emirates who had their MacBook and asked for theirs in return. However, when they received their MacBook back, it was locked with an Activation Lock that Apple refuses to disable. The author speculates on how the Activation Lock may have been activated and discusses the frustrations of not being able to unlock their own device despite being the rightful owner. They urge readers to turn on Find My on their MacBook to avoid a similar situation.
