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.....
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
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).
