Apple is yet again facing a class-action lawsuit and this time it is because of its super-thin MacBook keyboards.

Current laptops of Apple, including the MacBook and the MacBook Pro, have started to get users complaining about their ‘butterfly’ keyboards, first introduced in 2015, that get jammed easily when faced with minor dust or debris and are also loud to type on. This issue has led to users sue the company, first spotted by Apple Insider.

Many users complained about the keyboard. There was even a parody song about those keyboards that gathered over 150,000 views. A San Francisco-based law firm Girard Gibbs has now filed a class-action lawsuit against Apple on behalf of two users Zlxuan Rao and Kyle Barbaro.

The complaint read, “This action is brought on behalf of individuals who purchased model year 2015 or later Apple MacBook laptops and model year 2016 or later MacBook Pro laptops. The MacBook Pro is marketed and sold as top of the line—the 15-inch model’s starting price is $2,399. But the MacBook is defective: its ‘butterfly’ keyboard is prone to fail. Thousands of consumers have experienced this defect. When the MacBook’s butterfly keyboard fails, the keys stick and no longer register keystrokes. As a result, the user cannot type.”

The lawsuit also states that Apple’s own troubleshooting that involves turning the laptop horizontally and blasting it with compressed air, doesn’t work either. Also, the lawsuit read that the keyboards aren’t being properly handled under warranty, as per Business Insider.

According to 9to5Mac, the lawsuit goes on to claim that Apple ‘knew that the MacBook is defective at or before’ the release. The lawsuit seeks damages, legal fees and also calls for Apple to disclose the keyboard flaws and replace the defective units, including reimbursements for the initial laptop purchase.
