I can't get my computer to recognise my laser

Ah, I didn’t catch that you were running Mac. There are a lot of issues with USB on Mac. There is a lot of info in this thread: Macbook doesn't recognize my ruida machine - #19 by LightBurn

In the end, it might behoove you to switch to Ethernet. It’s way more stable, and a lot faster in the end. USB and Mac have had issues for a long time. (Mac issues, not LightBurn caused)
