I use Aperture. I bought a Nikon D7100. I work in Raw, but I can not use Aperture. jpg. is no problem. Is there an update? In Lightroom 7 I have the same problem.

You'll have to wait for the next raw support update.
The camera is not yet supported in Aperture, but usually Apple is pretty quick to support the latest Nikon and Canon cameras.
The list of curently supported cameras is here: Apple - Aperture - Technical Specifications - RAW Support
