It’s showing up in my system report as “FT232R USB UART”
So is it possible for the board to be defective, even considering it worked from a Windows machine?
find /Library/Extensions/ /System/Library/Extensions/ -iname "*FTDI*.kext"
/Library/Extensions//FTDIUSBSerialDriver.kext /System/Library/Extensions//AppleUSBFTDI.kext
kextstat | grep FTDI

FTDI Driver Installation manual
Since 10.9 (Mavericks), OS X has included built-in partial support for some FTDI devices in VCP mode. Starting with 10.11 (El Capitan), Apple’s own driver seems to be sufficiently comprehensive that many customers will not need to install FTDI’s own VCP unless they wish to use its advanced features such as baud-rate aliasing and configurable latency times.

I’m wondering if this CH34x driver is causing issues somewhere, since I don't know how to uninstall it (or remember when and if I even installed it in the first place!)Quote
The printer kit you have is the new EG-1 v2. It uses the ZRIB control board. You should not need to install anything other than the Arduino IDE software (latest version). It includes the necessary drivers. You can manually install the FTDI drivers found here: [goo.gl]

As for when it works when booting the Mac, well that makes senses, since when booting the Mac in is power user mode(root) in the background and loads up the drivers FTDI correctly with theses permissions. But if you unplug the printer, then upon re-connection your user does not have proper permission to load the FTDI drivers correctly.

An ownership or permissions problem is preventing the system from making the device accessible. Check that the driver is owned by root and wheel. The most common symptom is the group for FTDIUSBSerialDriver is not wheel. To change the group, login as root and perform the following script in a Terminal window
cd /system/library/extensions
chgrp -R wheel FTDIUSBSerialDriver.kext
drwxr-xr-x@ 3 root wheel 102 19 Oct 23:57 AppleUSBFTDI.kext
