This post was published 4 years 6 months 6 days ago. Therefore, it may well be out of date. Do not reply on the contents of this post being accurate. Boot Camp and Parallels are two ways of running Windows (and other OSs) on an Intel Mac. Now, there’s a third way, Fusion, from VMWare.
It’s currently available as a free Beta download. There’s also an option to purchase a license for $39.99 (half what the RRP will be), which will be valid for all version 1 release candidates.
I’ll be trying this soon and comparing it to Parallels v3, which I’m currently using.
