Hi, 

Anyone knows how to use STM32 USB as virtual com port under MAC OS? Do ST provide official driver for this?

MacOSX recognizes CDC(-ACM) devices (ie. virtual COM port) without ANY extra driver. Just plug in the device.

You'll see two objects under /dev for the single CDC device, for example.

/dev/cu.usbmodem001

/dev/tty.usbmodem001

You may use either one. As of the difference of cu. and tty. refer to this link
