The MacBook Air is renowned for its sleek design, lightweight build, and powerful performance. However, one common frustration that users face is when the keys on their MacBook Air stop working. This issue can be infuriating and may impede productivity. In this article, we will explore the potential causes of malfunctioning keys on a MacBook Air and provide comprehensive solutions to help you get back on track.
Understanding the Problem: Common Symptoms of Keyboard Malfunction
When the keys on your MacBook Air don’t respond as expected, it can manifest in various ways:
