COM ports not appearing under Mac OS

I'm using an ST-Link V2 with an STM32 (Blue Pill). I connect it to a Mac running High Sierra and the device correctly shows up under USB in the System Report:

STM32 STLink:

 Product ID: 0x3748

 Vendor ID: 0x0483 (STMicroelectronics)

 Version: 1.00

 Serial Number: Qÿm?IpIIX"?‡

 Speed: Up to 12 Mb/sec

 Manufacturer: STMicroelectronics

 Location ID: 0x14200000 / 18

 Current Available (mA): 500

 Current Required (mA): 100

 Extra Operating Current (mA): 0

But there're no /dev/tty.usbxxxxx or /dev/cu.usbxxxx ports, so the device doesn't show up under Arduino IDE or other environments.

Any idea what's going on? I know for a fact that I used this ST Link a few months ago to program the same STM32 and I got it to work. I also just tested it on another Mac laptop and got the same results.

Is there anything I need to install or I need to do in order for those COM ports to appear correctly?

Thanks.
