CrossOver is an application that allows users to run Windows and other applications on different platforms such as macOS, Linux, and Chrome OS. It provides an easy way to install, manage, and run Windows apps on these platforms without needing to install a separate Windows license or virtualize the entire OS. CrossOver also offers a wide range of features, such as seamless integration of Windows apps with the host OS, support for Microsoft Office, compatibility with thousands of Windows games, easy app installation, and a streamlined user interface. It is a great tool for users who need access to Windows-only software on other platforms.
CrossOver emulates the windows application layer. parallels creates a fully virtualized machine and requires the installation of Windows, as if it were a physical computer.
