Quicken has been a load of crap for 25 years. There are bugs in Quicken 2007 that have been there for more than 10 years, through succeeding paid releases of the software, without being fixed. Intuit got their start with products for the Mac, yet they always treated it as the bastard stepchild. It was always inconceivable to me that their Mac and PC software shared neither capabilities nor a common file format. In fact, for years, if you wanted to convert Quicken for Mac data to the PC (or vice-versa) the only option was a paid service where you paid them something like $200 for the privilege of migrating your data. (Would that it were even POSSIBLE to migrate mine.)
The fact that they failed to adapt Quicken for the Intel CPU architecture despite having years and years to do so... well, they are completely undeserving of our business. Even QuickBooks (which I, too, use for different financial stuff) was orphaned and then resurrected a few years later. And all this time, Intuit CEO Bill Campbell sits on Apple's board of directors. It's a travesty.
Anyway... I gleaned info on getting Snow Leopard to run under Parallels/VMware from a variety of sites, but the basic info here:
http://hints.macworld.com/article.php?story=20081031054054546 is probably as good a synopsis as you'll find. It talks about Tiger, but the same technique works for SL. Here's another very useful post:
http://blog.rectalogic.com/2008/08/virtualizing-mac-os-x-leopard-client.htmlI found that, inexplicably, after modifying a disk image of the SL Installer DVD, I couldn't boot the Virtual Machine using that virtual image (Parallels would always complain that it wasn't OS X Server.) So I burned that same image to a DVD and then set Parallels to boot from the DVD drive, and then the SL Installer booted up just fine. Not sure why it wouldn't boot from the image, but this may save you some frustration.
Make sure that immediately after installation, you go and fix the ServerVersion.plist file on the virtual HDD. I found that I had to do it BEFORE I left the installer (when the installation finishes, DON'T click to continue; instead go up and choose Terminal from the menu and go fix that file, or you won't be able to boot.) It should be possible to fix the file from the host OS by mounting the virtual HDD and accessing its system files, but I couldn't get Parallels to mount the client drive. This is an important step, I ended up having to install SL three separate times before I got it right.
Good luck!
