First 10.12 broke Nikon Transfer such that the CF card in my D810 (or any dual-card body) wouldn't show up. OK, so I made the SD card primary. With 10.12.2, RAW files don't transfer properly; the copy on the Mac is damaged (or incomplete) and unusable. Just to make sure, I did some transfers to my MBP running 10.12.1, and the NEF files transferred correctly. Other methods of transferring from the card work properly. The issue for me is that my workflow over the last 4 years has depended on Nikon Transfer for making folders named as I want them and placed where I want them, and renaming the files as they're transferred. I can do all these things manually, of course. Anybody else notice this?
