Mac-version 10.12.6

Which OS?

Also, you may have an issue with conflicting drivers, as discussed here:

OS X and Connecting to an GRBL board

Thanx so much for that Link. Not exactly my problem, but it reminded me to look for drivers for a 340 Chipset, then I found this link : (discussion about 340 Drivers and OS X) which led me to this file on GitHub OS X 340 Drivers I had a chance to install and reboot, then sprint downstairs to test. All seems well, at least Y axis moved 10cm. I did have to delete and redefine a device, but then it allowed me to select a new USB port. I’ll post more results when i get more of a chance to play…
