A Parallels Desktop virtual machine (VM) is an ideal environment for using a beta release of an operating system. By its very nature, a beta OS will contain bugs, unfinished features, and other 'gotchas' that might play havoc with your documents or your work. A VM isolates those issues in a sandbox-like environment so that any such issue will not damage anything. I have been using VMs like this for years, and I have written up bugs in beta OSes released both for Apple and for Microsoft so that the final OS release will be free of these issues.
