There’s a nice introduction to virtual computers in Eastman’s Online Genealogy Newsletter. The article informs the reader that virtual computers are made possible by software that lets you to run another operating system (OS), like Windows, while simultaneously running the host OS, in our case, Mac OS X. All this techie talk simply means that with the help of another piece of Mac software, like Parallels Desktop 6 for Mac or VMware Fusion 3, and a copy of Microsoft Windows 7
you can run Windows programs without leaving the comfort of your familiar Mac.
I have a copy of both, so if there is interest I can write more about them or make some videos. Contact me using the form on the “Contact” page with what you’d like to see. You could also post your questions about virtual computers in the comments on this article.
