Apple has slightly lengthened a cable in the 2018 MacBook Pro, that was said to be responsible for the “stage lighting” problem in the 2016 and 2017 MacBook Pro.
Some MacBook Pro users have previously complained about a problem with the display, where the backlight to illuminate the screen would illuminate improperly as a result of damage to the cable, and show a “stage light” effect at the bottom of the display. The problem, which affected models produced in 2016 and 2017 and at the time of original report was said to impact the 2018 model as well, was narrowed down to a thin flex cable that connected the motherboard to the display wearing down over time.
According to iFixit, Apple has seemingly fixed the issue in its 2018 models, by lengthening the cable. A comparison of the 2018 and 2016 models found the cable had been extended by just 2 millimeters. As it was found to have been changed in the 15-inch MacBook Pro disassembled by the venue as well as in other customers’ 13-inch model, it is likely that Apple made it a general design change to all variants.
“This is significant because it gives the backlight cable more room to wrap around the board and not come into contact with the board as the laptop is opened past 90 degrees,” advised iFixit teardown engineer Taylor Dixon.
