Digital Negative Redux

It's been a couple years since I was begining to learn how to make inkjet negs. I wasn't using one of the commercial books. I was pointed to a couple online articles explaining how to set up Photoshop, and print test wedges to calibrate for your process.
Well, I want to get back into it. As a start Cyanotype (classic and new), Gum, and eventually Ambrotype.
I have both Mac and PC. Is one better to use for diginegs? Is a certain PS version better?
I still have a good supply of Pictorico. Are there any updated sites (free) with instructions and info on making the best diginegs?
