I haven't tried it myself from Cocoa, but I would think you can use a
mixture of Quartz and Cocoa.

When you are drawing with Cocoa, you can get the current CGContext
using:

CGContextRef currentContext = (CGContextRef) [[NSGraphicsContext
currentContext] graphicsPort];

From there you should be able to use:

CGContextSetRenderingIntent(currentContext, <whichever
CGColorRenderingIntent you care to use>);
