I have been running Linux since 1999. When I started digital, in 2001, my Coolpix 995 only produced .jpg and .tif, so it was easy to do pp with Gimp. By the time I got my D200 in 2006, I had already started using Bibble. The transition to AfterShot was easy, and they do support my D500, and they have started supporting Z bodies. Unfortunately, Corel keeps relying on deprecated libraries to make new builds of Aftershot, so for now I run it on a machine which I keep at an old version of Linux, but that has its limits. I can't keep an otherwise modern machine with an old OS on it, and drag down the rest of my environment with that. That is annoying, because they do provide updates for recent Nikon machines
On the other hand, I am able to run a VM. Which got me to try Windows 10 in a VM with 4 cores and 8 GB of RAM. I am still testing Aftershot, Lightroom and Nikon NX in that sandbox. But I can say that if I am forced to run anything Windows, in the context of working Nikon RAW files, I am leaning towards Nikon NX, which is sure to support all new Nikon cameras.
Meanwhile, I am prepared to run AfterShot in a VM with my older version of Linux.
