OSX includes terminal emulation software that you can use from the command line, so we only need to install the USB drivers for the cable.
Install Drivers
Next, install the latest drivers for the cable chipset.
There's two possible chipsets. The older cables use Prolific brand, the newer cables (as of 2017) use SiLabs brand. If you're not sure which you have, just install both drivers! There's no risk and the cable will work no matter what
Prolific Chipset
For the "Prolific Chipset" cable, grab the drivers from here
And if you're using an older version of Mac OS X (10.8-10.6) then try this Prolific driver version 1.5.1.
SiLabs CP210X Drivers
If you are running Mac OS X , please use the SiLabs drivers here
If you are using Mac OS 10.12.6 (Sierra) and you cannot upload with the latest Mac OS VCP driver, please try the legacy v4 driver below. Note you will need to uninstall the v5 driver using uninstall.sh (in the driver package)
