Why Apple Butterfly Keyboards Are So Bad

The Apple butterfly keyboard, used in MacBooks from 2015 to 2019, is widely considered a major design failure due to its high failure rate, uncomfortable typing feel, and susceptibility to dust and debris. The mechanism was prone to sticking, repeating keystrokes, and failing entirely, leading to multiple lawsuits and Apple’s eventual return to a scissor-switch design.

Background: How the Butterfly Keyboard Came to Be

In 2015, Apple introduced the 12-inch MacBook with a radical new keyboard design. The goal was to make the laptop thinner and lighter. The butterfly mechanism, named for its shape, was flatter and more stable than the traditional scissor switch, allowing for a thinner profile. Apple touted it as a major engineering achievement, claiming it was 40% thinner and offered four times more stability than previous keyboards. However, this design sacrificed key travel (the distance a key moves when pressed) and, more critically, reliability.

How the Butterfly Mechanism Works

A traditional scissor-switch keyboard uses two interlocking plastic pieces that form an X shape. When you press a key, the scissors hinge, allowing the keycap to move down and up. The butterfly mechanism, in contrast, uses a single piece that pivots from the center, like a seesaw. This design is flatter and more stable, but it has a critical flaw: it leaves very little room for the keycap to move and no space for debris to escape. The mechanism is also more delicate and prone to breaking if even a tiny speck of dust or a crumb gets underneath.

Common Problems and Failure Modes

The butterfly keyboard suffered from a range of issues, many of which were widely reported by users and covered by the media:

• Sticking keys: Keys would get stuck in the down position, requiring a hard press or a tap to release them.
• Repeating keystrokes: A single press might register multiple times, or a key might repeat continuously without being pressed.
• Unresponsive keys: Some keys would stop working entirely, requiring a restart or a firm press to function again.
• Dust and debris sensitivity: Even a tiny particle could cause the mechanism to fail. Apple’s own repair program acknowledged this, offering free repairs for affected models.
• Noise and feel: The keys were loud and had a shallow, harsh feel, which many typists found uncomfortable and fatiguing.

Apple’s Response and the Repair Program

In 2018, Apple launched a repair program for butterfly keyboards, covering MacBook and MacBook Pro models sold between 2015 and 2017. The program offered free repairs for affected keyboards, but it was not a recall. In 2019, Apple introduced a new version of the butterfly keyboard with a silicone membrane designed to prevent debris from entering. However, this did not fully solve the problem, and the design was still widely criticized. Finally, in late 2019, Apple discontinued the butterfly keyboard and returned to a scissor-switch design in the 16-inch MacBook Pro, and later in all new models.

Comparison: Butterfly vs. Scissor Switch

The return to scissor switches was a tacit admission of failure. Here’s how the two designs compare:

• Reliability: Scissor switches are far more robust and less prone to failure from dust and debris.
• Key travel: Scissor switches offer more key travel (typically 1mm to 1.5mm), which feels more comfortable and natural to most typists.
• Stability: Butterfly keys were more stable at the edges, but this did not compensate for the other drawbacks.
• Repairability: Butterfly keyboards were notoriously difficult to repair, often requiring the entire top case to be replaced. Scissor switches are easier to service, though still not user-replaceable in most modern MacBooks.

Cost and Impact on Users

The butterfly keyboard’s failures had significant costs for users. Out-of-warranty repairs could cost hundreds of dollars, and even with the repair program, many users experienced repeated failures. The design also hurt Apple’s reputation for quality, leading to a class-action lawsuit that was settled in 2022, with Apple paying $50 million to affected customers. For those who could not afford repairs, the keyboard made the laptop virtually unusable, as the built-in keyboard is essential for a laptop.

Alternatives and the Current State

If you are looking for a MacBook today, all current models use the scissor-switch Magic Keyboard, which is a significant improvement. For those who still own a butterfly-keyboard MacBook, options include using an external keyboard, cleaning the keyboard carefully with compressed air, or taking advantage of Apple’s repair program if still applicable. Some users have also had success with DIY repairs, but this is not recommended for most people due to the complexity and risk of further damage.

Frequently Asked Questions

Are all butterfly keyboards bad?

Not every single butterfly keyboard failed, but the failure rate was significantly higher than typical keyboards. The design was inherently flawed, and even the later versions with the silicone membrane did not fully solve the problem. Many users had no issues, but a large number experienced at least one failure.

How do I know if my MacBook has a butterfly keyboard?

Butterfly keyboards were used in MacBook (2015-2017), MacBook Pro (2016-2019), and some MacBook Air (2018-2019) models. You can identify them by the very flat keycaps and the lack of a visible hinge mechanism. Apple’s repair program page lists the specific models covered.

Can I fix a sticky butterfly key myself?

Sometimes, using compressed air to blow out debris can temporarily fix a sticky key. However, this is not a permanent solution, and the problem often recurs. If a key is completely unresponsive, you may need to replace the entire top case, which is expensive and not recommended for most users.

Is the Magic Keyboard (scissor switch) really better?

Yes, the Magic Keyboard is a significant improvement in both reliability and typing comfort. It has more key travel, is quieter, and is far less prone to dust-related failures. Most users find it much more pleasant to type on.

Why did Apple stick with the butterfly design for so long?

Apple likely stuck with the design because it allowed for thinner laptops, which was a key design goal. The company also believed it could fix the issues with revisions, but the fundamental design was flawed. The public backlash and lawsuits eventually forced a change.
