Arduino nano 33 sense board does not connect in MAC (2013 BookAir, Catalina)

I've just received my new nano 33 sense BLE board. Got it shipped all the from US to INDIA
I've installed the library "Arduino nRF528x Boards" with the IDE.
I've reboot my computer but my nano is not detected in the Manager , no serial port found.
The led power is on the board. Yellow LED blinks each sec.


Make sure the USB cable is completely plugged into both the Arduino board and the PC.

You may have a damaged/defective or charge-only USB cable. Try a different cable.

I just got the board (shipped from US to India) was excited to some ML. But, I'm so disappointed, not even able to connect to the board. "Port" Just shows only "BlueTooth Incoming" ports, there is no other option. Any idea? When I connect with USB cable, one LED is solid and other LED (Yellow) is blinks every second.
