How to increase charging current on OSX computers when using USB 2.0 from 500mA to 2000mA?

Authenticated Apple devices can charge at up to 2100mA x 5V. Apple-non-fast-charging and non-Apple devices are relegated to much slower 500mA x 5V charging. Thus, while my OnePlus One phone itself supports a 5V charging current of up to 2000mA, it is not possible to charge at higher than 500mA. Does a method exist to increase the available "Extra Operating Current (mA)" from 0 to the max value possible? I am interested in both OSX and Android related solutions.
