There have been several reports from Mac users who say they have connected USB-C hubs and docks to their machines, resulting in their Mac becoming non-functional. The affected Macs’ screens go blank and unresponsive after connecting the dock. Many of the users reporting issues apparently bought hubs and docks from fly-by-night firms.
