If you’re a MacBook Air user, you know the sinking feeling that accompanies a malfunctioning keyboard. In a world where typing is part of our daily routine, having a key or two that just won’t respond can be incredibly frustrating. But fear not! In this comprehensive guide, we will delve into the various reasons why your MacBook Air keys might not be working, along with effective solutions to resolve the issue.
Common Reasons Keys on MacBook Air Are Not Working
Understanding the underlying causes of why keys are misbehaving on your MacBook Air is crucial for a quick resolution. Here are some of the most common reasons:
