Has anyone gotten an arduino working on high sierra?
I got it to show up in the usb section of system report but it doesn't show up in the com port of the arduino editor.

I figured out what was going on with my Chinese Arduino clone. I needed ch340g drivers.

I deleted anything called “usbserial.kext” in /Library/

Find them with:

Code: Select all

find /Library -type d -name usbserial.kext

Then installed the ch34* drivers from the manufacturer:

When prompted to reboot I force killed the installer.

Then I ran:

Code: Select all

kextload /Library/Extensions/usbserial.kext

Then it showed up in Arduino!
