A lawsuit filed in federal court claims that the keyboard used in all the MacBook Pros and MacBooks made in the past few years is defective. The plaintiffs request that this be made into a class-action lawsuit, and that Apple be required to replace all the affected keyboards at no cost to users.

The lawsuit also requests punitive damages because, as the plaintiffs claim, Apple continued to build and sell laptops with the “butterfly” keyboard even though the company knew it was defective.

The butterfly keyboard in recent MacBooks draws frequent complaints. And these have now escalated to the point where an online petition is requesting that Apple recall every MacBook Pro released since 2016.

These laptops are super-slim, and so are their keyboards. Reducing the thickness left room for very little key travel, resulting in accusations that even a small speck of dust underneath one of the keys can cause it to stop functioning.

Imagine an iPad Air sliced in half. The top half peels up to reveal a pin-sharp high-res screen. The other half has a full-size keyboard that’s almost flat.

This is the new MacBook. As usual, Apple’s latest crazy-thin laptop is dividing the tech punditsphere.

Because it comes with only one port, some think this machine is too radical, too new. It’s been called a glorified netbook — short on features, and, to really rub it in, high on price.

But I’m smitten. We have one in here at the Cult of Mac offices, and I’ve been putting it through its paces. Here’s what I found.
