NEF Files Locked After Transfer


I just bought a D750 (and love it). When I transfer NEF files from the SD card to my mac (OSX 10.11.6), the files appear in the finder as "Locked".  In preview, I can't edit them in any way unless I duplicate them as a TIF file.

In another post, someone said, go into Nikon's view software, right click, and go to "Protect Files" change from 'protect' to 'Unprotect'. I did this both in NX View 2 and in ViewNX-i and when I go to 'protect' its as if the file is NOT protected, as the only I option highlighted for me is "PROTECT" (as the file is not already protected). ("Unprotect" is greyed out.)

Note that in ViewNX-i, I can indeed open the file and look at the image.

When I open the filed in photoshop it seems to open without issue.

So is this just a Preview issue? Is the photo not really 'locked'?  My concern is, I don't want to transfer 1,000s of images into meticulous folders and have issues later like a year from now when I know longer have the files on the SD as I will have reused them by then.

Also note the image is not "locked" on the camera and also the SD card is not in the locked position either. And I just updated my OS software and Nikon software just to be sure, but the issue remains.

Please help!

I know there's a similar thread on this topic, and I tried everything on there, and it didn't work--and my situation is slightly different, so I entered a new question. Thanks in advance for all your help!
