The difference is in the fan setting for the blower and (on many cars) changing the system so that it recirculates the cabin air rather than cooling outside air.
The compresser runs all the time, unless you have the belt disconnected, so there is some loss of mileage inherent in that. However the load is greater when it is working - so that turning on your AC does reduce mileage. How much? Depends on the car, various studies estimate from as little as 1 to as much as 3 mpg. Bigger engines have more torque to spare and it makes less of a difference.
As to changing the setting from Norm to Max (I thought they both used to be characters on Cheers...) the difference is probably too small to measure unless you're using the passenger cabin to cool your adult beverages.

I think generally the Max A/C in a car recirculates the cabin air to cool better. Unless the compressor is actually loaded down more in the Max A/C mode, you might expect even a negligible gain in fuel efficiency in the Max mode due to the reduced aerodynamic drag of the closed fresh air intake.

"Max A/C" is just another name for what is recirculate on other cars. There is no difference, in fact if anything it probably uses less gas because the air doesn't have to run through the filter and takes less work to cool. But the difference is only marginal. Having your A/C on only wastes gas in SUVs at higher speeds; otherwise, a more fuel-efficient car will keep you from having to sweat it.
