I use my aged MacBook Pro to run Carbide Create plugged into the Shapeoko 3 on USB, all I did was put an old magsafe PSU in the Shapeoko bench so it doesn’t go to sleep whilst running the machine.
When I go to the shed I plug in the USB, power up the Shapeoko and tell CC to connect to the machine, not had any issues with that.
You could also consider just running CC on an Raspberry Pi and sending your jobs over the network to that, there’s a whole thread about that option
