A:Answer If your iMac has a USB-C/Thunderbolt 3 or 4 port, the Mini Dock will work. This device is Plug-and-play, no driver installation is required. However, please keep in mind Bus-powered USB hubs only draw power from the connected device such as your computer's USB port. If you are connecting high-powered devices like printers, scanners, or external hard drives, we recommend a USB hub with external power.
