What are some “must have” Mac OS X programs?
What are the must-have programs to install on a Mac with Macports? One per answer please...
Or, if you prefer not to use macports, please indicate so and why.....
The programs you find you need to use.
I know that sounds like a smart-ass answer, but I install programs from MacPorts (or any programs) as I need them.
mipadi gave the proper answer: install what you need.
That said, the main MacPort I've installed is GraphViz (the Mac version doesn't integrate as nicely into the command line). Its a graph drawing app that operates based on a list of commands (think LaTeX).
