The current generation of MacBook Pro laptops uses flexible ribbon cables to connect the display to a display controller board beneath the Touch Bar. These cables wrap over the board, where they’re secured by a pair of spring-loaded covers—and they’re subjected to the stress of bending with every opening and closure of the laptop. Within a seemingly short time, those cables are starting to fatigue and tear. The backlight cable is generally the first to go, producing the infamous “stage light” symptoms, and eventually giving out entirely when the laptop is opened more than about 40°.


In July 2021, the class-action lawsuit was dismissed by US District Judge Edward Davila, who concluded the plaintiffs failed to prove the defect was a safety hazard and that Apple had concealed knowledge of the problem, Law360 reported.

The plaintiffs appealed against that ruling in hopes of reviving their case, claiming it violated California’s Consumer Legal Remedies Act and Unfair Competition Law. It also alleged fraudulent concealment under common law theory and deceptive trade statutes in Washington, Florida, New Jersey, Michigan, Alaska, Missouri, Massachusetts, and Texas. The Ninth Circuit has now sided with Apple, determining the company has no duty to disclose the flaw.
