Hi All! I purchased an Airtel 4g Dongle and the installer provided with it does NOT work on Mac OS X 10.11 (also known as El Capitan). The Dongle I have is a Huawei 3372h-607. I've posted step by step instructions here for others.
The same procedure should help most other Huawei USB Dongles. Here is a list of supported devices
