another option, which uses the color space of one of the colors:
BOOL equal = [color1 isEqual:[color2 colorUsingColorSpaceName:[color1 colorSpaceName]];

Not sure if that would be the best thing to do if say color one was in NSCalibratedBlackColorSpace or color2 was made using NSPatternColorSpace.

I only mention this because I've had many issues in the past when trying to convert color spaces like this.

NSColor *rgb1 = [color1 colorUsingColorSpaceName:NSCalibratedRGBColorSpace];
NSColor *rgb2 = [color2 colorUsingColorSpaceName:NSCalibratedRGBColorSpace];
BOOL equal = rgb1 && rgb2 && [rgb1 isEqual:rgb2];

I'd personally go for this one.
