WinMac is a free program that allows Windows 95, 98, NT4, 2000, Me, and XP users to add a Macintosh-style menu bar to their system. WinMac is written in Visual Basic v5.0 by Michael Mallory. It is currently capable of mimicking System 7, Mac OS 8 and 9, Mac OS X Server, and Mac OS X Aqua menu bars. WinMac also includes a user-requested custom Mac OS Brushed Metal bar.

The WinMac project began in 1996 when Ritchie Chow set out to create a Macintosh Menu Bar for Windows 95 and NT. He was able to produce a very impressive product for its time, offering Windows users a Mac OS Platinum (v8.x, 9.x) Menu Bar months before Mac OS v8.0 was even released. However, Ritchie became unable to continue updating the WinMac project, so development stalled, albeit just temporarily.

In 1998, Ritchie Chow transferred the rights of the WinMac Project to Michael Mallory. He picked up right where Ritchie left off, making major code optimizations, adding Aqua Support (again, before the actual release of Mac OS X), and making WinMac better able to report information about the computer on which it runs.
