Q: Airtel 4G Huawei dongle not working in Mac 10.11 el capitan [Solved]

I recently purchase Macbook air installed with mac 10.11 el capitan and also an airtel 4G dongle with huawei make and model number E3372. As i tried to install airtel 4G huawei dongle, the screen read

no software to install

I then was on google searching for solutions. I found many websites recommending to switch off rootless in Mac by turning on recovery mode to install the airtel 4G drivers and dongle. I suppose that is not necessary here.

Solution is documented in the below link
