MacOS CH340 Driver info and files
Latest macOS Sierra/High Sierra-compatible driver for devices using the CH340G, CH34G or CH34X chipset. This chipset is used in several Arduino-compatible clones and serial-to-USB cables.
Do not install if you have the current macOS Mojave 10.14 or later. macOS Mojave 10.14 (released in October 2018) includes a CH34x driver by Apple. If both Apple's and the OEM driver are installed, they will create conflicting non-functional serial ports.
