ch340g-ch34g-ch34x-mac-os-x-driver

Ultima versión del driver compatible macOS Sierra para dispositivos que emplean el chipset CH340G, CH34G o CH34X. Este chipset es empleado en varios clones de Arduino-compatible y en cables serial-to-USB.

Introduction

Version 1.4 (2017-01-11) of the OEM driver for the CH34x chipset.

Version 1.3 (2016-09-27) of the OEM driver causes a kernel panic (a.k.a. crash) when installed on macOS Sierra.

Installation

  • Remove the old driver by issuing one of the following commands (depending on your installation):
    • sudo rm -rf /System/Library/Extensions/usb.kext
    • sudo rm -rf /Library/Extensions/usbserial.kext
  • Restart your Mac.
  • Double-click on the CH34x_Install_V1.3.pkg file.
  • Restart your Mac.
  • Plug in your device. It should now be listed under the /dev directory. Examples:
  • /dev/cu.wchusbserial1410
  • /dev/cu.wchusbserial1420

Installation with Homebrew-Cask

  • Install the driver by the following commands:
    • brew tap mengbo/ch340g-ch34g-ch34x-mac-os-x-driver https://github.com/mengbo/ch340g-ch34g-ch34x-mac-os-x-driver
    • brew cask install wch-ch34x-usb-serial-driver

Troubleshooting

Note: disabling System Integrity Protection is no longer necessary, as the current drivers are properly signed by the OEM. If you're having problems, they're almost certainly not related to SIP. The instructions below are left only for reference purposes. If you had previously disabled it (especially if you did so completely), you are strongly encouraged to fully re-enable SIP.

If, and only if, the device is not recognized after the installation (or you cannot install the driver), please disable System Integrity Protection:

  • Reboot your Mac into Recovery Mode by restarting your computer and holding down Command+R until the Apple logo appears on screen.
  • Open the Terminal (Applications > Utilities > Terminal).
  • In the Terminal window, type in csrutil enable --without kext (or to fully disable: csrutil disable) and press Enter.
  • Restart your Mac.
