Ch340 Driver Mac Os Catalina
In some Mac OS, the original driver from factory might not work well. In that case, please inform us your detail MacOS version. We will send you proper driver. Please contact us :William@wemacro.com
After receiving the driver from us, please follow steps by steps as below.
Installing NodeMCU driver on MAC The NodeMCU is using USB 2 Serial Communication called CH340, you can download the driver at the link below, you have to install the driver package as you used the NodeMCU on Mac. After you install the CH340 driver you need to test the serial communication by filtering using a bash command see it below. Most Creality Printers use a FTDI F232R USB to Serial adapter chip for them to use USB. If you have a V1.1.4 board you will want to use the CH340 Driver instead. If you are having issues communicating with your board try installing one of the drivers below. I recently upgraded my MacBook Pro to Mojave. Now I'm not able to connect to my Arduino board with ch340g usb-to-serial chip. It is a Arduino board with AtMega 328 and ESP8266 integrated. I downloaded the drivers from the Chinese website for the ch340 and also removed old installations, like some tutorials tell me. Under the pop-up menu, you’ll see Select the OS X installer. (macOS used to be called OS X.) If you have only the Catalina installer on your Mac, Install Disk Creator will automatically.
1,Remove the original driver. /samsung-frp-bypass-tool-for-mac.html.

Please press “command + shift + G”, Type “/Library/Extensions/”, go to the Extensions folder.
Sorry for the slow reply on this one. This seems to be an issue between the CH552 programmable USB microcontroller used by M5Stack for the serial interface, and the relevant driver in Mac OS X Catalina. The serial control signals used by esptool.py for auto-reset were not getting through to the hardware. I have several low-cost development boards that use the CH340/CH341 usb-to-serial chip for usb communication. Unfortunately, with OSX Sierra, the official CH340 driver cause a Kernel Panic (freeze + reboot) of the Mac when a device is connected. The reason is that the drivers are not signed correctly.
/windows-10-altum-pro-iso-download.html. It this folder you will find “usbserial.kext” if you had installed the original driver from chip factory. Select this kext and move it to trash.
2,Install the driver we send to you. Meanwhile, please make sure you are using the latest version of WeMacro Mac software. Restart the Mac after installation of driver. If you are using Helicon Remote, please also make sure it’s at least 3.9.7.
Select the device list in wemacro control program,press “connect”,(please notice only press connect button once.)Press “Save”. It will show “save done”. Then it will work.
After installing your new, shiny, macOS update you might have found out like me that plugging in any device that relies on a CH340/CH340G/CH341 device (like the ESP8266 based Wemos D1 Mini) immediately throws a kernel panic. Not ideal…
So far, I did not find a solution to making it work, but read below for the solution to avoid getting kernel panics.
I will update this post once I have a working solution.
What you need to do is to remve the problematic kext/driver that is throwing the kernel panic. This kext should be mentioned in the log you can find in /Library/Logs/DiagnosticReports with a .panic extension.
In my case it was: last loaded kext at 6898626041: wch.usb.usb
You will then need to find where this kext is, in my case is was under /System/Library/Extensions with the name usb.kext. Your names and locations might differ unfortunately.
I was able to confirm it was indeed the driver by doing a cat usb.kext/Contents/Info.plist grep wch.usb.usb and seeing if it returns anything.
I then removed this and can plug a Wemos D1 Mini without my computer panicking on me.
Using the adapter
As mentioned here, the previously working signed driver does the same thing, so I have no free solution yet to using these serial adapters on macOS Sierra. I will update this post when I i find a solution.
Thanks to our old pal Björn (original drivers post on his blog) and to @sebastianAPW that told me about it, we now have a free, working solution for CH340, CH341 on macOS 10.12 Sierra
Winchiphead signed drivers for CH340-CH341, OS X 10.9 to macOS 10.12
Pay for drivers
One of my readers (thanks Lee) let me know that he tested a paid for driver that worked for him. I have not tested it, as it will remove any motivation of finding a free solution 😛

I thought you may like to know that https://www.mac-usb-serial.com/ (costs €7.90) seems to work if you unpack the installation packages and manually kextload the driver 🙂
