We know that our customers will want to know about compatibility between the new M1-based Macs and CalDigit’s docking solutions.
All of CalDigit’s docks are fully compatible with the new M1-based Macs including the ability to charge a laptop and more. However, the only limitation is that the new M1-based Macs cannot support dual “Extended” displays through their Thunderbolt 3 ports. This means that when using any dock, users cannot extend their desktop over two displays, and will be limited to either dual “Mirrored” displays or 1 external display depending on the dock.
Users with Intel based Macs, and Windows PC users can still benefit from dual “Extended” displays when using CalDigit docks.
This is not a limitation of CalDigit’s Thunderbolt or USB-C docks, but of the Thunderbolt 3 ports on the new M1-based Macs.
All other functionality of our docks including laptop charging will work as normal.
