Word 5.1 for the Macintosh, released in 1992, was a very popular word processor due to its elegance, relative ease of use, and feature set. However, version 6.0 for the Macintosh, released in 1994, was widely derided, unlike the Windows version. It was the first version of Word based on a common codebase between the Windows and Mac versions; many accused it of being slow, clumsy and memory intensive. In response to user requests, Microsoft offered a free "downgrade" to Word 5.1 for dissatisfied Word 6.0 purchasers. The equivalent Windows version was also numbered 6.0 to coordinate product naming across platforms, despite the fact that the previous version was Word for Windows 2.0.
