MacBook Keyboard Troubleshooting Guide

Apple's Butterfly keyboard and how it works?

Every gadget manufacturer wants to have the thinnest and lightest device. In 2015, Apple introduced the 12-inch MacBook, which uses ultra-thin keys for "innovation." These buttons feature a "butterfly" switch, named after a pair of delicate "wings" in the key, which are much shorter than traditional scissor keyboards.

Apple continues to use these switches in all MacBook Pro and MacBook Air released in 2015 to improve stability or reduce noise.

What complaints about Butterfly keyboard?

For some, though, the MacBook’s keyboards are facing another issue entirely. Instead of keys no longer working, certain keys — such as the E key and the spacebar — have been inserting two E's or spaces for each click. Dual class action lawsuits (1, 2) have accused Apple of using these keyboards despite knowing their inherent issues.

How to fix the keys stuck in MacBook?

First of all, you'll need to hold the MacBook in the air, with its keyboard deck at a 75-degree angle, so it's almost vertical, but leaning slightly away from you. Then (after attaching the can of compressed air's straw into its nozzle), spray the stuck or affected keys from left to right.

Repeat the above steps while holding the left side of the MacBook and holding the right side of the MacBook again.

In the summer of 2018, Apple introduced a keyboard service program for MacBook and MacBook Pro to provide free service and repair for the affected keyboard.
