NEDIVER

I also have a macbook pro, some things to consider;

A lot of these programs have you buy a copy of windows and install it. This takes up A LOT of extra space just to run a dive planner.

Some good things about Fusion is that it can make a "fusion friendly" version of your old PC and transfer it to your new Mac (if you are just switching to Mac, at OP stated).

All in all, my buddies have all run Apple Boot Camp, Fusion and Parallels. All of them say that Parallels is the most functional and problem free. But all of them said that they all have problems!

I choose not to install or run any of the window programs on my mac and currently use my old PC for Dive Plan software until the rest of the world realizes that Mac is the new standard. Especially for us photographers (Aperture software rocks!), and those who like to make videos.

So, my humble recommendation is use your PC as an "expedition notebook" for dives until you have found the right software for you.
