(I'm not sure whether this was really necessary the crashing still kept happening until I did step 2. Macfusion brings servers from across the internet directly to your Mac's desktop Complete rewrite of Macfusion / Macfusion2 Mount files and documents as a 'Volume' in the Mac OS X Finder Work with your files using your favorite Mac OS X applications directly. I'm just reporting it for completeness.) In VMware Fusion, go to Virtual Machine -> Settings -> Advanced, and set 'Hard disk buffering' to Disabled. If your Fusion Drive is causing slowness/crashing issues or appears as two drives instead of one in the Finder, its no longer working as a Fusion Drive. I would also tend to agree that it is probably hardware and I am thinking that it is video. I have to say though that this is kinda strange because, lots of Macs out there are really not upgradeable in the video card department. I can't upgrade the video card as far as I know and yet, I think this is the source of the problem. My point in saying that is that VMWare fusion was created specifically to run windows and other OS's on a mac and if the crashes are due to a video problem or some other hardware problem that causes the Whole Mac to crash, not just the windows 7 VM then what does that mean? Anyway, whatever the problem is, it happens often enough that I am going to have to stop using Fusion to do any of my critical work.

I'll have to use boot camp to make a clean windows partition and run that way.

A bit of a pain switching back and forth, but if I'm not crashing then I can live with it.
