CH340 Drivers for Mac OS 10.12 Sierra

If you are using an Apple computer with the latest OS (10.12 Sierra) you may find that plugging in a CH340 chip based Arduinos (used to control the Sienci Mill One) may cause your computer to crash. Luckily there is a driver that makes everything work thanks to Adrian Mihalko.

You can find a link to drivers at I have tried this on my Macbook Air and have been able to connect the CH340 based Arduinos with no issues.

If you are a Windows user, there should be no driver issues. Plug your Arduino in, and if you don’t already have the drivers installed, the computer will auto-download them over your internet connection.
