The original operating system for the Apple [http://www.apple.com/] Macintosh Computer
(which was not the first computer from Apple - it was actually a fourth or more generation computer).

These days, most Macs are coming with [MacOS X] installed.

Note however that [Daniel Steffen] and others continue to provide
[Tcl], [Tk], and even [Tclkit] in formats suitable for MacOS (both 68k and Power PC!).
