Usb Ch340 Driver For Mac

I am running Mac Sierra, and after following your instructions, installing the driver and running the boot command 'csrutil enable --without kext' listed below, my Mac now kernel panics and reboots when plugging the Arduino Nano into the USB port. Download drivers for CH340 IC for windows 7, windows 8, windows 10 and also for MAC users. Check out how to install drivers for Arduino UNO, NODE MCU and Arduino Nano which have ch340g usb to serial converter IC. Like under Yosemite, any CH340 or CH341 based usb to serial adapter will not install because El Capitan enforces kext driver signing. Since no updated and signed drivers came from WCH the only way to install them is to disable kext signing verification on both Yosemite and El Capitan.

UPDATE 4 Jan 2016
I have seen this driver reported as working without disabling kext signing Signed CH340 Driver

Thanks Björn.
I have not tested it as i have already done the below and am fine with it but you can give it a try. Hit me up on @tzapulica if it doesn’t work.

There are a lot of devices using a CH340, CH340G or CH341 serial adapter that no longer work under El Capitan. NodeMCU 0.9, WeMos D1 Mini and a lot of Arduino clones use these chips. You might have discovered that your Arduino IDE can no longer find a serial port in El Capitan.

Like under Yosemite, any CH340 or CH341 based usb to serial adapter will not install because El Capitan enforces kext driver signing.

Since no updated and signed drivers came from WCH the only way to install them is to disable kext signing verification on both Yosemite and El Capitan. Unfortunately this leave your system a bit less secure than Apple intended but if you need to play…you need to play. Just use your own head before deciding to do this.

Under OS X 10.11 El Capitan Apple change the way kext signing can be disabled by introducing “System Integrity Protection” and a new cli util “csrutil”.

To disable kext signing you will need to do the following:

Reboot and press CMD+R immediately after the chime to enter Recovery Mode
Open Terminal from Recovery mode
run the command csrutil enable --without kext
reboot

You should now be able to install the serial adapter drivers from WCH Chinese CH340 CH340G CH341 Drivers

You can also inspect the status of the System Integrity Protection with

csrutil status

from terminal. Output will be something like:

System Integrity Protection status: enabled (Custom Configuration).

Configuration:
Apple Internal: disabled
Kext Signing: disabled
Filesystem Protections: enabled
Debugging Restrictions: enabled
DTrace Restrictions: enabled
NVRAM Protections: enabled

This is an unsupported configuration, likely to break in the future and leave your machine in an unknown state.

More info about System Integrity Protection that i found useful.

I have tested this on a Retina MBP with El Capitan GM trying to get a NodeMCU board working with Arduino IDE. It worked !!! I could see my CH340 based device under the Tools/Port in Arduino IDE.

I hope it’s useful for someone as I couldn t find all the info in one place.

Introduction

Version 1.5 (2018-07-05) of the OEM driver for the CH34x chipset.

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

Unplug any CH34* devices.
Unload the old drivers if running:
- sudo kextunload /Library/Extensions/usbserial.kext
- sudo kextunload /System/Library/Extensions/usb.kext
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
Double-click on the CH34x_Install_V1.5.pkg file and install (no need to reboot)
Instead of rebooting, you can force quit Installer after it completes.
Load the new driver:
- sudo kextload /Library/Extensions/usbserial.kext
Plug in your device. It should now be listed under the /dev directory. Examples:
- /dev/cu.wchusbserial1410
- /dev/tty.wchusbserial14210 (driver version 1.5)

Installation with Homebrew-Cask

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

Troubleshooting

If the device doesn't show up under /dev, check the section 'Security and Privacy' in System Preferences for any notices about blocked software.

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.

Arduino Uno Ch340 Driver

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.
