The Federal Aviation Administration has banned certain 15-inch MacBook Pros with potentially defective batteries from US flights. The move, which follows Apple's June recall announcement, is part of a general FAA policy on devices with defective batteries. The FAA says it alerted airlines about the recall in early July. The agency also says it informed the public on social media around the same time, though it didn't get much attention at the time. Regulators in the European Union have also restricted the recalled MacBooks from use on European flights. Affected laptops were mostly sold between September 2015 and February 2017.
