Overview
CrossOver is a Microsoft Windows compatibility layer available for Linux, macOS, and ChromeOS. This compatibility layer enables many Windows-based applications to run on Linux operating systems, macOS, or ChromeOS.
CrossOver is developed by CodeWeavers and based on Wine, an open-source Windows compatibility layer. CodeWeavers modifies the Wine source code, applies compatibility patches, adds configuration tools that are more user-friendly, automated installation scripts, and provides technical support. All changes made to the Wine source code are covered by the LGPL and publicly available. CodeWeavers maintains an online database listing how well various Windows applications perform under CrossOver.
Versions
CrossOver Linux
CrossOver Linux is the original version of CrossOver. It aims to properly integrate with the GNOME and KDE desktop environments so that Windows applications will run seamlessly on Linux distributions. Before version 6, it was called CrossOver Mac Office. CrossOver Linux was originally offered in Standard and Professional editions. CrossOver Linux Standard was designed for a single user account on a machine. CrossOver Linux Professional provided enhanced deployment and management features for corporate users and multiple user accounts per machine. With the release of CrossOver Linux 11 in 2012, these different editions merged into a single CrossOver Linux product.
