A new application called WhatCable allows Mac users with Apple Silicon to assess the performance of their USB-C cables for free. The app utilizes data already collected by the Mac's port controller chip to provide insights into cable capabilities, such as speed and power delivery, without requiring root access.
WhatCable can help users identify issues with their cables by displaying real-time performance metrics and compatibility information. While it offers a free version, a paid Pro version is available for additional features, and the developer is also considering a Linux version.
WhatCable empowers Mac users to optimize their USB-C connections by revealing real-time performance data. Keep an eye on upcoming updates, including potential Linux support and the Pro version features, which promise enhanced diagnostics for power users.
