If you were an early adopter of Apple's slimmed-down MacBook, then this may apply to you. According to the company, a "limited number" of laptops sold between its launch in April of 2015 and June 2015 have USB-C cables that could fail due to an unspecified "design issue." You can identify the faulty cables that need replacing by reading the label, which says "Designed by Apple in California. Assembled in China." without a serial number after that. The MacBook was one of the first devices to support the new standard when it arrived last year, and since then we've come to learn that finding quality cables is both harder and more important than ever.
