FWIW, I dtopped using Nikon software a long time ago. It was always slow, buggy, and broke every time Apple even issued a minor update ot the OS. But, beyond that, Nikon's software always installed dozens (or even more) files all over the operating system for no obvious reason. Some of these insinuated themselves deep into the operating system and were very difficult to find and eliminate. I think it's a better idea to keep that software off your Mac, but that's just my observation.
In a comment above one user indicated that Apple is a "bit slower" than Adobe supporting the D4s, and compares the (still unready) support from Apple to Adobe's April 8 release date of their support. This is misleading, since for a long time before the official release Adobe made the beta software available to D4s users to they could use the Adobe products with the new camera. Obviously, they understand the needs of these customera and have done everything they can to support them.
Apple, on the other hand, still does not support Nikon's current flagship camera, months after it has been released. They haven't made any effort to get beta software to anyone or help in any other way. They not only don't support the camera but provide no information whatsoever to their users as to when the support will be forthcoming. This is not a professional way to treat their customers, and it doesn't make it look they like are particularly concerned about those customer or with providing reasonable competition for Lightroom.
