CodeWeavers has announced that CrossOver Mac will be arriving this year in late July or early August 2006. Pricing will be at $59.95 for single-user licenses, with volume and educational discounts available. CrossOver Mac will support a number of Windows applications to run natively within Mac OS X using Wine, enabling the user to run Windows applications without having a copy of Windows installed on their system.
"Wine is an Open Source implementation of the Windows API on top of X and Unix.
Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, Mac OS X, and Solaris.
More information can be read in the articles Why Wine is so important, and Debunking Wine Myths. If you are wondering how well a particular application works in Wine, please examine the Applications Database. For installation instructions and step-by-step help with running Wine, take a look at the User Guide.
Wine is free software. The licensing terms are the GNU Lesser General Public License."
