@johnson Can you get the customer to send in the cura-lulzbot.log? It will help determine what the issue is.

@Yahuba Please Can you flash a Mini 2 on High Sierra 10.13.6 and see if you have any issues?

@karrad I was able to flash a Mini 2 with a 0.5mm toolhead on High Sierra 10.13.6 with no issues.
Steps I took:
Uninstalled instance of Cura LE and cleared cache
installed Cura 10.6.20
At launch, selected Mini 2 with 0.5 toolhead when prompted
Connected to printer
Navigated to printer settings and auto-flashed FW
Flash completed succesfully.

Also repeated the same steps but without connecting to printer first and was still able to successfully flash without crashing.

@johnson We are able to confirm flashing successfully on high sierra 10.13.6 w/o issue. I would suspect some security measures are in place preventing communication. See if you can gather information on what they have security packages they have installed or their IT team might have installed.
