A free Mac app called WhatCable solves the biggest problem with USB-C cables: They all look alike, but they are not all the same.
Plug a USB-C cable into your Mac, and WhatCable can tell you how much power it can deliver, how fast it can transfer data and more. And a pro version for power users serves up even more data about the cables in your collection. The app’s earning accolades online (and hit No. 4 on ProductHunt), so I decided to put it to the test.
