Nov 30, 2016 CH340 Drivers for Mac OS 10.12 Sierra Posted on November 30, 2016 May 28, 2020 by siencilabs If you are using an Apple computer with the latest OS (10.12 Sierra) you may find that plugging in a CH340 chip based Arduinos (used to control the Sienci Mill One) may cause your computer to crash. Mar 20, 2019 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.

The CH340 chip is used by a number of Arduino compatible boards to provide USB connectivity, you may need to install a driver, don’t panic, it’s easier than falling off a log, and much less painful.

Apple's macOS Mojave is a great software update for most users. But, it isn't for those who are using an Nvidia graphics card in their Mac Pro or inside of an external GPU enclosure, so let's talk.
May 06, 2019 2-3 weeks? I think you are a little optimistic. Remember that the last time Nvidia released new graphics cards (the current 10xx series) it took Nvidia more than 10 months to release drivers for MacOS Sierra and then High Sierra. Even if Nvidia were to start work now I believe it will take at least months before Mojave drivers are available.
So, I have Arduino Nano CH340x working on Mac OS (Mojave), Ubuntu 18.04, Elementary Linux (forget version) and openSuSE Leap 42.3 Malachite. It was not at all necessary to install drivers or make them on the Linux machines - but I did install them for the Mac. Downloaded from the Chinese site.

Download the Windows CH340 Driver
Unzip the file
Run the installer which you unzipped
In the Arduino IDE when the CH340 is connected you will see a COM Port in the Tools > Serial Port menu, the COM number for your device may vary depending on your system.

Older Windows Driver Version and Instructions

~~Download the Windows CH340 Driver~~
~~Unzip the folder.~~
If you are running a 64Bit Windows: – run the SETUP_64.EXE installer.
If you are running a 32Bit Windows: – run the SETUP_32.EXE installer.
~~If you don’t know, try the 64 bit and if it doesn’t work, the 32 bit.~~

Ch340g Driver Mac Os Mojave 8

The following github has up to day pkg files for 1.3, 1.4 and 1.5 at time of writing, thanks to Joshua Wallis for bringing this to my attention…

Direct Download Links (from the github repo above):

See the github link above for installation instructions if you need them.

Previous macinstosh downloads if the above doesn’t work for you…

~~(V1.3) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11) and Sierra (10.12)~~ Windows remote apps on mac.

~~Inside the zip file you will find a PDF and a “pkg” file, short version, double click the pkg file, the PDF has some extra information.~~

~~OSX Sierra (10.12) Note~~

~~A kindly user, Maarten Segers reports~~

~~FYI, the driver documented here WILL crash on OSX Sierra.~~

~~Make sure to use this one instead: https://github.com/MPParsley/ch340g-ch34g-ch34x-mac-os-x-driver~~

~~I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go.~~

~~See uninstalling information at the bottom of the page if the driver causes problems for you.~~

~~Here is an older version of the Mac driver, NOT FOR 10.12 Sierra~~

Ch340g Datasheet

Drivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. If not you can download the Linux CH340 Driver (but I’d recommend just upgrading your Linux install so that you get the “built in” one).

Uninstalling From Macinstosh

A couple of Mac users have said “the driver crashes my mac Sierra how do I uninstall”.

B5 used to split reinvestments into two transactions: a credit to the account followed by a buy, so that the cash balance correctly remained the same. Best personal financial management software for mac. My comment above about B6’s lack of significant digits making my B6 records disagree with my brokerage statements I now regard as trivial; there is a much more serious problem: reinvested dividends.

Ch340g Driver For Windows 7

Firstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. You could download it directly from the Manufacturers Website in case they have issued an update since I wrote this page.

Secondly a quick google search reveals that this is how you uninstall:

Ch340g Driver Mac Os Mojave Update

Open a terminal and type: cd /Library/Extensions/
Verify that the .kext file is present: ls | grep usbserial.kext
Output should be: usbserial.kext
Then type: sudo rm -R usbserial.kext
Verify that the .kext file has been removed: ls | grep usbserial.kext
Output should be empty.
After you should remove the files stored in receipts folder: cd /private/var/db/receipts/
Find the enties: ls | grep usbserial*
Output should be: codebender.cc.ch34xinstaller.usbserial.pkg.bom codebender.cc.ch34xinstaller.usbserial.pkg.plist
Remove each one of the files of the above list: sudo rm -r filename`
