A US federal judge has ruled in a lawsuit alleging that Apple sold faulty MacBook Pro laptops despite being aware of quality issues. Called flexgate in some circles, the problem is with MacBook Pro machines sold since 2016 that have notoriously brittle flexible display cables that apparently start to wear out after just a short period of use. This results in weird display anomalies, including the "stage light" effect, when too much backlight leaks through the bottom bezel of the panel. In the lawsuit, the plaintiffs allege that Apple's numerous preliminary tests, which allegedly included stress tests, should have brought the cable issue to the company's attention. "The court finds that the prepublication testing allegations combined with the allegations of substantial customer complaints are sufficient to show that Apple had sole knowledge of the alleged defect," Judge Edward Davila wrote in his order.
