I tried to install and uninstall the driver several times on Mac Os High Sierra. When I tried the above commands I got no results neither. To be honest, I dont know what else try. I have attached a couple of sceen shots.

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.
I have a Hackingtosh macOS High Sierra 10.13.6 and I want to use a 802.11n WiFi USB stick and I tried some drivers found on the internet but nothing helps.
Up until the last High Sierra security update 10.13.2, my Canon LBP6670 (with the existing driver setup) worked perfectly. I connect the printer directly via USB to my 2017 iMac 27' 5k computer. Since the update it reported that 'The printer is off line', which it wasn't? So, I deleted the driver (using the - in the printer system preference).

USB 2.0 gigabit adapters are limited to maximum speeds of 480 Mbps by the USB 2.0 bus, while USB 3.0 bus allows the USB3-E1000 to realize the full potential of a Gigabit network, since it isn’t.

Update - Feb 2020

These instructions are no longer required for macOS Mojave 10.14 or later. Updating to the latest macOS version should be enough to make Nanos based on CH340G chipset work. In fact, installing these drivers on macOS Mojave 10.14 or later could cause OS issues!

Original Post

I recently bought some really cheap Arduino Nanos. These were based on the CH340G chipset. Unfortunately, when I loaded the Arduino editor and tried to push code onto one of them, I discovered that there was no USB serial driver available to select.

The Mac already has Arduino USB drivers pre-installed and I’ve not had problems uploading code before. It turns out that some of the really cheap nano clones use different serial loaders to those used by genuine arduinos (or more expensive clones). My guess is that this is done to reduce licensing costs.

The Nano clones I bought cost me less than £3 each so I can’t really complain if I need to mess about a bit to get them working.

There have also been reports that plugging in a nano clone that is based on any of the CH340 chipsets causes the kernel to panic in macOS Sierra. This appears to be the case if you have installed compatible drivers on a previous version of macOS.

It turned out to be really easy to get these cheap nanos working by installing a compatible USB serial driver. The hardest part was finding a working driver that is compatible with macOS Sierra. The driver I ended up using can be downloaded freely from this GitHub repository

Warning: Do not install if you have the current macOS Mojave 10.14 orlater.

The instructions in the above repo explain how to install the drivers. In my case, I didn’t have any kernel panic issue to resolve so I didn’t need to manually delete any drivers. I simply ran the pkg file and rebooted my MacBook.

After installing the new driver I was able to upload code to both the CH340G based nano clone and the standard nano.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Learn how to upgrade to macOS Big Sur, the latest version of macOS.

Check compatibility

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.

If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.

These installers from the App Store open automatically after you download them:

macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion

Your web browser downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

Install macOS

Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

You might also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.
