The Apple laptops in question are some 15-inch MacBook Pros sold between September 2015 and February 2017. Apple issued the recall in June, saying it had “determined that, in a limited number of older generation 15-inch MacBook Pro units, the battery may overheat and pose a fire safety risk.” (Bloomberg)

How in the world are they even going to be able to enforce this? I would wager that many laptop owners have no idea which laptop they have and, if it was bought secondhand, they are unlikely to have received the recall notice. How is TSA going to know if you replaced the battery or not?
