MacBook Pro Stage Light? Taming That Pesky Screen Glitch

Seeing strange vertical bars or a "stage light" effect on your MacBook Pro screen? You're not alone! This frustrating issue, often manifesting as bright, uneven illumination, can be caused by various factors, primarily related to the display cable or the graphics processing unit (GPU).

First, try a simple restart. Sounds basic, but it can sometimes resolve temporary software glitches. If that doesn't work, consider updating your macOS to the latest version, as software updates often include fixes for display-related problems. If the issue persists, it's likely a hardware problem.

Unfortunately, a failing display cable is a common culprit, especially on older models. In this case, a repair is necessary. Consult an Apple Authorized Service Provider or a reputable repair shop. They can diagnose the exact cause and provide a repair estimate. While a DIY repair might seem tempting, MacBook Pro screens are delicate, and professional intervention is often the safest bet to avoid further damage. Getting your MacBook Pro looked at by a professional is always the best decision.
