Hi, thanks for your feedback. I actually have read the troubleshooting tips but they didn't help me so far. But I checked with a windows laptop and there the lidar is still working. I still don't know my issue with macOS, but will update you when I could figure out.
Update: earlier than expected I can tell you already that the lidar is working again with my MacBook without any changes done. Only thing I did was to plug it in on my Windows laptop and run an example script.
