Hi Nic - on any Linux system - and the Mac is Linux based - try typing
in a terminal window.
dmesg
This might require root privilege
At the end of the of output in the terminal window will be the device
and system port being used.
For example, in the case where you unplug the device and plug it back
in, on my system it prints out
[755460.454330] ftdi_sio 1-1.3:1.0: FTDI USB Serial Device converter
detected
[755460.455664] usb 1-1.3: Detected FT232RL
[755460.459439] usb 1-1.3: Number of endpoints 2
[755460.463865] usb 1-1.3: Endpoint 1 MaxPacketSize 64
[755460.468770] usb 1-1.3: Endpoint 2 MaxPacketSize 64
[755460.473483] usb 1-1.3: Setting MaxPacketSize 64
[755460.478739] usb 1-1.3: FTDI USB Serial Device converter now attached
to ttyUSB0

That is possible.
Windows and linux identified my chip as made by FTDI. I wasn't sure
how to check on mac.
I was/am using a CT-1 from ttl2usb dot com.
Hard to tell if ttl2usb dot com sourced a bad chip or not.
I have had this serial device for quite a few years. But the last time
I used it I was using windows 7.

What data lead were you using? If it uses a Prolific USB-Serial
bridge, it may be an old type of chip, or a clone. Either way
Windows
(and many Mac systems) will not use them. (Without compromising the
security of your system by blocking automatic updates and then
manually
installing an earlier driver suite.)
But Linux (even recent distro's) use them just fine, regardless. Had
similar issues locally, with a group that uses dozens of Baofeng
radios. All the interface leads used "hookey" chipsets. A
Windows box
and a Mac, both failed. My old Dell running Mint, "just worked"...
Counterfeit IC's are rife in that part of the gadget after market.
Take care.
