What operating system are you using?
What Arduino device are you trying to connect to?

If you are running Windows, does the device show under Device Manager?

You may have a look at this just in case the driver is not behaving

If you are running Linux, if you type 'dmesg' you should see some similar to the following:
NOTE: This is with Ubuntu 16.04.6 LTS

If you have the Arduino IDE installed locally, is the board seen there?

I have MacBook Pro, Funduino MEGA2560 = Arduino MEGA 2560

In my experience, it is hit and miss when dealing with knock off Arduino boards.  It's best to stick with the Arduino branded boards.

However, have you looked at the output of system.log either from the command line or from the Console option?

Ex:
tail -f /var/log/system.log

I am not sure if any other driver is require for the Mac OS but you could try installing the Arduino IDE and see if it picks up the board from that.
