Bluno Nano - Arduino IDE

I just purchased a Bluno Nano recently and try to program it with Arduino IDE using Macbook pro. I could not find it in the port selection. I have replaced a bunch of micro usb but it din't work. I have also downloaded a firmware driver for Mac. The Arduino IDE works fine when I connect it to Nano BLE with the same micro usb. What is going on with the Bluno Nano and what can be done?
