"Arduino" is an open source series of hardware platforms, combining a specific microcontroller with various communication interfaces and pin connectors. The term "open source" means the original designer has put the design specifications into public domain; and grants use to anyone. Anyone is allowed to manufacturer Arduino systemboards using the original technical drawings and specifications.
Open-source Arduino systemboard manufacturers, are starting to make systems with the CH340G and CH341G Serial/USB controller IC circuit (a communication interface). This blog entry, offers a guide to using the controllers with Mac OS X computer operating system.
CH340G/CH341G Serial/USB Chip?
The CH340G and CH341G controllers require software drivers be installed in the computer used to write software for Arduino systems with the controllers. The software drives are developed and offered free from various Internet resources.
MAC OS X
Mac OS X 'Sierra' software driver for devices using the CH340G, CH34G or CH34X IC interface/controller. This communication interface/controller is used in several open-source Arduino systemboards and serial-to-USB Adapter cables.
2017: Version 1.3 (2016-09-27) of the OEM driver, for the CH34x controller (IC chip), currently causes a "kernel panic" (software "crash") when installed on MAC OS X 'Sierra'. To resolve this issue, try the latest release of this software-driver:
