π° What Happened
A free Mac app called WhatCable can tell you the truth about your USB-C cables. Many USB-C cables look the same but work very differently. Some charge fast, some are slow. Some can transfer data at high speeds, others cannot. WhatCable reads the data your Mac already collects about plugged-in cables and shows it to you. The app works on Macs with Apple Silicon chips. A similar hardware tester was discontinued, so this software approach is a handy replacement. It is free to download and easy to use.
π The Backstory
USB-C is the standard connector for most modern gadgets, from phones to laptops. But not all USB-C cables are the same. Some support fast charging and high-speed data. Others only do basic charging. Manufacturers do not always label their cables clearly. So people end up with a drawer full of cables and no idea which does what. A cable tester used to cost $8 but was discontinued. WhatCable solves this problem for free. It gives users the information they need to pick the right cable for the job without buying extra hardware.
π― Why It Matters
Most people have tangled piles of USB-C cables and no clue which ones are good. This app saves time and money by helping you use the right cable for charging or transferring files.
