TechThis free Mac app reveals the truth about your mystery USB-C cables

A free Mac app offers an intuitive way to find out what an unidentified USB-C cable can actually do. A previously highlighted $8 cable tester could quickly indicate whether a cable was likely fast, slow, powerful, or weak, but that device has since been discontinued. For people with a Mac powered by Apple Silicon chips, the app provides a new way to assess their cables without relying on that discontinued gadget.
