It’s not exactly a secret that Apple’s updated MacBook and MacBook Pro have keyboard issues. The butterfly style switches — which Apple first introduced with the 12-inch MacBook in 2015, and then brought over to the MacBook Pro lineup with the 2016 redesign — are famously problematic, with the issue really coming into the spotlight after Casey Johnston wrote about them at The Outline. The new key switches have the unfortunate tendency to fail completely after just a single spec of dust or two manages to find its way under the keys, with a delicate design that makes removing them to clear out the offending dust a dangerous proposition that can destroy your keyboard if done incorrectly.

According to a report from AppleInsider, the 2016 MacBook Pro keyboards are more than twice as likely to fail than the older switches on Apple’s previous Retina MacBook Pro design, and there’s currently a pair of proposed class action lawsuits against Apple over the keyboard.
