Update
Spoke to the head of Software at Hasselblad and there is indeed a problem at Apples end. The workaround is to remove the Hasselblad RGB profile from user/library/colorsync/profiles AND library/colorsync/profiles before booting aperture for the first time, once you have done this you can safely put them back.
