Parallels Desktop is designed to run a variety of operating systems in virtual machines beyond just Windows. In addition to Windows, users can install and run various distributions of Linux, such as Ubuntu, Fedora, and CentOS. Parallels also supports other operating systems like macOS, which allows users to test different versions or run older applications that may not be compatible with the latest macOS release.
Moreover, users can create virtual machines for additional platforms, including older versions of operating systems for legacy software needs. One of the advantages of Parallels is its ability to provide seamless integration between the host macOS and the guest operating systems, enabling users to share files and perform actions as if they are running natively.
For the most current list of supported operating systems and specific details on installation, it is always a good idea to check the official Parallels website, as it frequently updates information regarding compatibility and features.
