A simple cable management tray can significantly declutter a Mac office space. By mounting a Thunderbolt dock under the desk using such a tray, users can conceal the dock and its associated cables, leaving the desk surface cleaner and more organized. This setup is particularly beneficial for those working from home with a MacBook Pro and external display, as it reduces the visible cable clutter associated with connecting peripherals. The cable management tray provides a practical solution for maintaining a tidy workspace.
