The problem is that the Apples color profile is apparently missing the conversion matrices required for the conversion to the profile. Essentially that means you can convert from the Apple Wide Color Sharing Profile, but you cannot convert to it. See LittleCMS issue #188 [1]. If the input images have the same profile, enblend keeps the profile for the output, too. The enblend itself operates in the CIELUV colorspace when the input images use the same profile, so it needs to convert both from and to the original profile. Because of the limitation of the Apple profile this is not possible in your case. I think the best option regarding keeping the color information correct is to convert the input images to a different profile that has similar or larger color coverage. I can't find the coverage of the "Apple Wide Color Sharing Profile" so I can't tell what standard color profile would be best, but I would start with the "Adobe Wide Gamut RGB".
