It appears that the serial driver on MacOS used to talk to the chip in Ruida devices is broken - there's a feature called 'flow control' that allows the Ruida to ask the PC to slow down if it's sending too fast, and on Mac (and Mac only) enabling this feature is rejected by the OS.
This release of LightBurn has built-in data rate throttling to keep it under the maximum rate supported by the Ruida. This fixes the communication issue for nearly every Mac user we've gotten early feedback from.
We're also working on another option - it's still being tested, but should be available soon, and will allow you to use WIFI to talk to a Ruida controller without any communication dropouts: https://lightburnsoftware.github.io/NewDocs/LightBurnBridge.html
