MacOS, it seems, has messed up a fairly critical function in the USB driver used to talk to the chip that the Ruida uses. The best option you have at the moment is to use a network cable, connected between the Apple Ethernet adapter and the Ruida controller. It takes a little more effort to set it up, but it’s not horrible.
We’re working on something that will allow you to use WIFI instead, with a small hardware add-on at the laser, but it’s going to take a little longer before we can start rolling it out.
