I've always avoided using Wine apps on OSX to avoid frustration. For Plotter, I always just used an old Windows machine. I came across my install CD the other day, so I thought I'd try to install it using Wineskin. It was so easy and it works so well I can't believe it. Even printing appears to be perfect. I have only found one very small issue. Bringing in reciprocity values from the included xml file does not work. Just look up the values and type them in. Two characters.
Now, using ExpoDev is much easier and I can dump my old Windows machine.
