This is CH340G USB To TTL(Serial) Converter, USB to TTL / USB-TTL /STC microcontroller programmer / PL2303 in nine upgrades plate with a transparent cover Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc. This USB–TTL converter is based on CH340G USB to Serial TTL converter chip. The module can be used for 3.3V logic level signals. Updated cask file with new URL, checksum, version. Removed no-longer-relevant warning.Updated readme with new version info and attempted to reword some NLA sections / strongly encouraged people to re-enable SIP and included a link to Apple documentation.
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…

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 🙂
