I have the ESP32 board with Silicon Labs CP2102 controller. When I connect it to my MacBook, I can get the details about this device using the command
system_profiler SPUSBDataType , but it is not listed in /dev as a virtual serial port - so I can't communicate with it.

I'm using the official driver downloaded from https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.
Any ideas how to make it visible in
/dev ? I have also Windows installed on the same computer where it works fine, so the HW and the USB cable are OK.

To use the CP2102 on a computer running Mac OS X, you should download and install the CP210x USB to UART Bridge VCP Drivers from Silicon Labs for Mac OS X. Additionally, we have older drivers that other customers have used successfully on both PowerPC- and Intel-based Macs running OS X version 10.3.9 or later, but these probably will not work on version 10.7 or later. I can confirm, the SILabs CP210x driver definitely does not work in Windows 10. I'm an embedded systems developer using this chip as the serial console for our SBC, and Windows 10 definitely does not recognize the device.

I found that macOS High Sierra has blocked the SiLabs kernel extension.
Here are steps to allow this extension: Minolta qms 2300dl drivers for mac.

The Allow button did not work for me, so I had to disable checking altogether:
