An ultra-thin keyboard from Apple for its MacBook laptops starting in 2015. Users have experienced problems with the keyboard, including poorly responsive "sticky" keys, repeating characters or characters not appearing on screen. As a result, in 2018, Apple created a Keyboard Service Program to resolve issues in its own repair centers or to reimburse users who sometimes paid several hundred dollars to have their keyboards fixed. A class-action lawsuit for financial compensation from Apple is pending in seven states. In 2019, Apple reverted to its previous keyboard design.
