A judge has granted class-action status to a suit against Apple over its controversial, allegedly defective MacBook "butterfly" keyboard design, agreeing that owners of any affected model in seven states qualify for the class.

Beginning in 2018, several MacBook owners in seven states filed suits against Apple claiming the company knew the butterfly-style switches were defective. In an order (PDF), made public on Friday, Judge Edward J. Davila of US District Court for the Northern District of California agreed to grant class-action status to the suit. All customers residing in California, New York, Florida, Illinois, New Jersey, Michigan, or Washington state who purchased a 2015-2017 MacBook, a 2016-2019 MacBook Pro, or a 2018-2019 MacBook Air now qualify for the class.
