MacOS can't find my NUCLEO-L433RC-P

Hi all! I bought a NUCLEO-L433RC-P, and have been trying to experiment with it. Unfortunately, I haven't got very far because MacOS doesn't seem to be recognizing that it's connected to my computer. It is plugged in with a simple USB cable.

I've tried multiple different cables, two different MacBook Pros, and all available USB ports on each MacBook. I have not modified the jumpers at all. When plugged in, the Nucleo's LD3 LED is lit green and not flashing, the LD4 LED is green and flashing quickly, and the LD1 LED is red and flashing slowly.

I was hoping to try MBed, but have also tried stlink and openocd to make sure that it wasn't a software problem. Neither tool could find the Nucleo - output of each is below.

Any idea what is going wrong here?
