CodeWeavers Inc. on Wednesday announced plans to support Intel-based Macs. CodeWeavers makes CrossOver and CrossOver Office. The software allows Linux users to use software designed to work on Windows operating systems without needing to have Windows installed. What's more, CodeWeavers offers custom software porting services based on CrossOver.
CodeWeavers is a corporate backer of Wine, open source software that lets Windows applications run on Linux systems not through emulation, but by implementing a compatibility layer that provides implementations of the Dynamically Linked Libraries (DLLs) Windows application depend on. (Wine itself is a recursive acronym that stands for "Wine Is Not an Emulator.) CrossOver is a proprietary version of Wine.
