Very nice - Works perfectly on macOS with driver install
For Fused FTDI-free USB to UART adapter (5V, M180v3)
I bought a couple of these adapters in an effort to find something simple, inexpensive, and FDTI-free that would work with my Mac. (Shipping took a while, but that's to be expected from China to the US.) The adapters seem to be well constructed, much better quality than the typical Chinese stuff you find on eBay. Documentation is quite good.
When I first plugged it into my Mac, no new serial ports showed up in any of my serial terminal apps. I went to the documentation link on the Tindie product page, and under the installation section for OS X I found a link to download the required driver:

Installation Summary for macOS 10.13 "High Sierra": Download and install driver. Allow kernel extension under System Preferences -> Security & Privacy when prompted. Reboot. Re-install driver. Reboot. Done.
Helpful Installation Notes: I really don't like disabling system integrity protection (SIP) to get drivers working, but I was pleasantly surprised to discover that on macOS 10.13 "High Sierra", you actually get prompted to allow the kernel extension under System Preferences -> Security & Privacy, rather than being forced to disable SIP, which can be a real pain to do, and also a security risk. After reboot nothing showed up, so I decided to give the installer another go. After the final reboot, everything worked! I did not need to disable SIP. :)
Finally, a macOS USB-to-serial converter that works!
