## What it is
A macOS kernel driver package for USB-to-serial adapters based on the WCH CH340G/CH34G/CH34X chipset, commonly found in Arduino clones and serial cables. It distributes signed OEM driver versions and installation/removal instructions, including a Homebrew cask.

## Use cases
- get ch340 usb serial adapter working on mac
- fix serial port for arduino clone on macos
- install ch34x driver via homebrew
- remove conflicting ch340 drivers causing kernel panic
- connect usb-to-ttl serial cable to mac

## When to choose
- you use a CH34x-based USB serial device on macOS Sierra or High Sierra
- you need to clean up conflicting OEM drivers before installing
- you want a Homebrew-managed driver install

## When to avoid
- you run macOS Mojave 10.14 or later, which ships Apple's built-in CH34x driver
- you need serial drivers on Linux or Windows
- you need a driver for other USB-serial chipsets like CP210x or FTDI
