Nuke61 - yes I agree with this. It seems that Capture NX2 is just engineered to work faster on Windows.
You, my friend, have a devious and crooked mind. You need healing. I would suggest this for you:

It costs under $4 and will heal your mind. Learn to take statements at face value. That is exactly what I was doing. Stating that I'm enjoying and love my Mac. No intention of bashing Mac - just saying that 1 out of the 12 things I do on my Mac is done better on Windows. Grow up, man.
You raise a very valid point. Somehow, I forgot to mention in my original note. Yes, it did take much, much longer to run this on a Mac. The same task would have been done on Windows in 2/3s of the time. BUT, Windows PC is very noisy - there's usually a 'roar' when it executes tough batch jobs like these... the Mac just purrs.
