MacTcl is the name the community has used over time for a version of Tcl that runs on MacOS operating systems.
The focus of this page is to provide pointers and brief tips on building Tcl/Tk (and extensions for it) on MacOS 7, 8, 9, and X.
For pointers on using Tcl on the Mac, including notes on installation of pre-built binaries, go to Apple Macintosh and Tcl/Tk instead.
