Free Mac App Tests USB-C Cables Effortlessly

For those of us who've ever wrestled with a questionable USB-C cable, the search for a reliable and affordable tester has been a long one. About three years ago, a fantastic $8 cable tester emerged, offering a quick way to determine if a USB-C cable was fast, slow, powerful, or weak. Unfortunately, that gadget has since been discontinued, leaving a void for many tech enthusiasts.

But for Mac users with Apple Silicon chips, there's now an even more impressive and, best of all, free solution: WhatCable. This innovative app works by tapping into the data your Mac already collects about connected USB devices. Apple typically doesn't expose this information to users, but WhatCable brings it to your fingertips.

Simply by clicking a small widget residing in your Mac's menu bar, you can instantly view detailed information about every USB-C cable and device connected to your system. This means no more guesswork or relying on flimsy indicators. Whether you need to confirm if a new cable supports high-speed data transfer or if a charger is delivering the expected power, WhatCable seems to be the go-to tool.

While the original hardware tester was a great find, its discontinuation left many looking for alternatives. WhatCable appears to fill that gap perfectly for the Mac ecosystem, offering a powerful diagnostic tool that's both intuitive and accessible. This development is a welcome one for anyone invested in the USB-C standard and looking to ensure their accessories are performing optimally.
