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.
