Problems importing into Lightroom classic

[deb_9184]

Hopefully someone can help or point me in the right direction. 
I got a new MacBook Pro and loaded the current version of lightroom classic. 
The problem is when I import photos into Lightroom (either using a card reader or directly from the camera) - the photos are NEF in Lightroom but on the hard drive they have shown up as Topaz Denoise. I deleted that to see if that would make any difference. 
But when I imported again - Lightroom had NEF but the hard drive had NX this time. 
I’m not tech so I have no idea how to fix this. 
I'm importing  COPY with copies going to designated spot on my hard drive. 
Thanks for any help as I’m really frustrated.

I suggest it is simply a 'File Association' matter that can easily be changed.

For your NEF files-  You might set the app to open NEF files as Photoshop.  (Why Photoshop?-  Lightroom-Classic can not 'open' image files- it can only open Catalog .LRCAT files.)

"NX" may be a file association with the Nikon app (Nikon Studio-NX).

Ultimately if you Import your photos to Lightroom-Classic it does not matter which File Association is set for your photo files.

I find the "Kind" displayed in Mac Finder ("Topaz Denoise", "NX") often misleading and unhelpful, as your example shows.

You may find it simpler to set FInder to show the file extension that's at the end of every file name (.NEF, .TXT, .JPG, etc.) and ignore the Kind column entirely.  To do that, in Finder do the menu command Finder > Settings, and select Show All Filename Extensions.

Many (most?) expert computer users end up doing this sooner or later.
